Was Kevin Cooper Framed for Murder? | True Crime Recaps

He is 100% guilty.

Wow boooo Kamala Harris she had the chance to help and refused

Yes, Kamela Harris then a prosecutor, denied the request for the DNA Testing on his behalf! Google it!

This case is insane. Mr. Cooper is getting a raw deal. I loved your image of how ridiculous it could have been for Mr. Cooper to have sat in all 3 seats at one time. I think you did a great job explaining the case, as I just heard of it, since Madam Vice President Harris has entered the race for President, and her so-called "Pro-law enforcement and Pro death penalty" opponents are using this case against her .

Who was the attorney general of the state of California as at this time?

Did Uhhhhh..Kamala Harris prosecute this case ?? Hmmm yeah yeah I think she didn.. she's a corrupt cop.. don't VOTE FOR HER 😡😡😡😡😡😡

This is so sad. Kamala had DNA evidence that could have tested to exonerate Mr Cooper, but she kept the evidence until it was too old to be tested.

Remember the good ol days when homophobia was normal? The world was a much safer place.

So the sole surviving victim still fingers Kevin and he does that because of racism?

I have some honest questions for the people who think Cooper is guilty:

1.) How do you explain away the blue bloody shirt that was found? The log in which it was referenced describe it as not only being a different color, but state that it was found on a different day (June 6th) in a different location (south of the canyon corral bar) from the tan shirt (which was found on June 7th NORTH Of the canyon corral bar.) Moreover, the log in which the shirt is referenced is only ever filled out if someone calls the department and they have to send someone to collect it. Since the tan shirt at trial was found by an officer as part of a search, there would have been no practical need to use the dispatch log.

The state's claim that there was only one shirt makes no damn sense no matter how you spin it.

2.) If Cooper entered the Ryen House to get their car keys, why didn't he ransack the place? It's literally what he did the last time he broke into someone's house to steal car keys (the Lori Stahl incident), and the only reason he'd even go inside is if he didn't know that the keys were in the ignition.

3.) If Cooper needed money, why didn't he take the valuables in plain sight? If the state's theory is true and he did it, he lingered long enough to grab a beer from the fridge, so he'd have definitely seen all the cash, credit cards and other valuables. The fact that he called his girlfriend hours before the murders asking for money shows he needed it, and in the aforementioned Lori Stahl incident he ALSO took the time to loot the place even though his primary objective was car keys.

Despite this the only things missing were a beer can, a hand towel found with the hatchet, and the station wagon. No money, and no sign he even looked for the keys despite that LITERALLY being the reason he supposedly would have entered.

4.) How did the victim's station wagon end up in Long beach? According to eyewitness testimony and prints on the car hood, the station wagon had literally been left there a short while before it was found on June 11th. Cooper had been unambiguously in Mexico since June 5th, and wouldn't leave until that day, when he boarded the sailboat of Owen Handy. If he had accomplices, how did he communicate with them and make arrangements? None of his known friends had ties to Long Beach, and cell phones weren't a thing back then.

5.) If Cooper washed himself off in the shower like the Prosecution argued, why was there blood on THREE different seats (the front seat, passenger seat, and back seat)?

6.) Why, after claiming multiple times that Pro Ked Dudes were unique to prisons, did the state backtrack once the defense provided airtight evidence this wasn't the case, and why did Judges Huff and Rymer parrot the state's claims despite it being contradicted by the trial record?

7.) If Josh was supposedly confusing three Mexican men who came looking for work with the killers, why did he tell Donald Gamundoy (the social worker who interviewed him before anyone else did) that the attackers were NOT Mexican (Gamundoy was often mistaken for Mexican so he asked "did whoever attack you look like me?" Josh pointed to "No" on the communication board, but Yes when asked if they were white.)

I've noticed that a lot of people who insist Cooper is guilty don't understand things like "chain of custody". IF the chain of custody is intact and verifiable than accusations of tampering can be shut down. They seem to think police shouldn't have to answer difficult questions about how evidence is handled

I've noticed that none of the people advocating Cooper's guilt have actually addressed the points in the video; the blue shirt and tan shirt in particular are quite damning. They also don't address things like "chain of custody" or the miraculous morphing evidence. DNA is good but it's only good if the chain of custody is reliable or the people doing it are honest.

The people insisting on guilt seem to think the police are beyond reproach and should NEVER be questioned

Thank you for the post. I just learned about this during this election period and Kamala.

As for VV-2; they tested it. It was only Kevin....but it was also drained completely save for residue at the bottom. Two of Cooper's experts have said that there was NO way testing in 1983 required that much blood. And the blood swatch having blood from another person is still bizarre.

The law firm royally botched it; they failed to examine undisclosed documents which would have clarified things. They seemed more intent on upholding the verdict and not making people question law enforcement.

Corrupt cops are rife in some of these murders .

Another thing that really should be mentioned: When Lee Furrow gave up DNA evidence he essentially admitted that he believed Cooper was framed. He refused to give up blood and his reason was "I'm not doing blood work and winding up on evidence like whatever they did to Kevin Cooper." That's....essentially an admission that he believes cooper is innocent. Moreover, he was unaware he was being recorded when he said it, implying it was a more spontaneous moment. As with the A-41 analysis I'd really like to hear people try to explain it .

Kevin Cooper killed that family. This video sucks.

I've noticed that none of the people who think Cooper did it have actually addressed the points in the video. They just throw poo around.

But why didn't they check the blood on the top that the wife took to the cops

This was while Harris was DA … this is where we have gotten cartoon to explain what happened?

In 2024 , “they and them” don’t indicate a number …. Sorry woke rules apply

My theory is that it started out with a few racist officers locking onto Cooper (they knew Cooper was on the run even before the crimes) and planting evidence, and the rest of the department roled with it due to incompetence/prejudice/a desire to avoid being called out on their other scandals. And once they realized the case was bullshit they were in to deep.

Most of the opposition to Cooper being innocent comes from the people who blindly trust the cops and judges; even the independent investigation naively tried to play down clear instances of incompetence (not even corruption just incompetence.)

* So let me get this straight.. Kevin Cooper happened to break out of jail only days before and broke into another house down the road from the family.
Kevin Cooper was previously convicted of burglary and rape.
His footprints and blood are at the crime scene.
His shirt had his blood AND the victim's blood ("true crime" didn't mention that...)
His DNA is on the cigarettes in the stolen car (didn't mention that either).
The surviving kid saw one man with big, bushy hair.
He fled the country and raped a woman in Mexico.

And all you "true crime" fans are gung-ho to release a psychopath who butchered a family.

All the evidence above points towards him. The man needed money and a car. He just escaped from prison. He needed their stuff. It makes sense.

Look at Cooper's rap sheet.

Read Josh Ryen's account, as the sole survivor. Truly chilling. Enraging.

Thanks, R...

Kevin Cooper escaped prison and it just so happened that right after that, and a short distance from the prison is where a family was murdered in cold blood and yall have the nerve to say it must be someone else. It couldnt of been cooper? Why? Because hes a good guy? Yalls white guilt makes me sick! Yall are pathetic!

My theory is that it started out with a few racist officers locking onto Cooper (they knew Cooper was on the run even before the crimes) and planting evidence, and the rest of the department roled with it due to incompetence/prejudice/a desire to avoid being called out on their other scandals. And once they realized the case was bullshit they were in to deep.

Whether Cooper did it or not the police DID Forge evidence and tamper with it; and to believe otherwise is to believe the sun goes around the earth.

You absolute degenerates lying about obviously guilty Cooper. Completely immoral and spits in the face of his victims. The evidence you omitted overwhelmingly points to Cooper as the culprit. Such an insult to that poor family.

cooper found innocent through ÐNA test !!!! go figure

Black have murdered over 100,000 white since emancipation.

At this point only a fool would trust the verdict without hesitation. It's telling that pretty much everything arguing his guilt has either sidestepped issues or lied outright. The blue shirt exists despite the fact that the independent investigation lied outright (they also tried to lie about how accurate testimony was and ignored a clear instance where Gregonis perjured himself about opening A-41 because that would mean admitting that he was a corrupt liar and that A-41 was worthless.)

At this point most of the people who think he did it are dishonoring the victims.

I notice that a lot of people hide behind the Morrison Foerster report: first off, at least a few of the things they said are lies (the blue shirt DID exist, and Laurel Epler's memory was corroborated by the log, so if a blue bloody shirt existed it backed Cooper up. They also claimed that Deputy Duffy's Pretrial testimony wasn't contradicted by his trial testimony....even though his trial testimony was literally the exact opposite. They also claimed Dan Gregonis initialling and dating the seal of the bindle containing A-41 wasn't proof he opened it, even though when you look at lab protocol it kind of is proof.) They also tried to play down real issues (David Stockwell's incompetence), and openly refused to subpoena documents from the state despite admitting it was important, while openly subpoenaing the defense (who were all too happy to cooperate and didn't need it.) The four experts they relied on weren't that credible. Three had close personal and professional ties with either the San Bernardino Sheriff's Department or individuals who stood to loose everything if Cooper was cleared. The fourth outright lied about a few things (he omitted the first person to speak to Josh about the attack, probably because what that guy said undermined his theory that Josh never actually saw his attacker)

Alan Keel got some very basic facts about degredation wrong, had personal ties with two people who stood to be badly humiliated if Cooper was exonerated, and has a history of cutting corners (Jane Dorotik spent 20 years in jail because of this and she's suing his worthless ass). Mark Lillienfield and Paul Delhauer also misrepresented things, both likely had friends in the San Bernardino Sheriff's department (the group accused of misconduct) and Lilienfield was a dirty cop who was indicted in several scandals. Even Mitchell Eisen said two things that point blank were not true (he said Deputy Dale Sharp was the first person to speak to Josh about what happened when it was actually Don Gamundoy. He also claimed Josh never stated he saw the attackers when in fact Josh did; Gamundoy, who was often confused for being Mexican asked "did they look like me?" Josh pointed to the word "NO", and did the same when asked if the attackers were black. He pointed to "Yes" when asked if the attackers were white.) No matter how you spin it, Eisen flat out lied by omitting Gamundoy (although even he conceded Josh's later memories were influenced.)

Honestly the only thing that keeps me from unreservedly declaring him innocent is some of the pretrial testing for A-41 and even THAT can be explained (for most of the results Blake would have relied on Gregonis, and given that Gregonis is both corrupt AND incompetent I don't trust him. For the one Blake was involved Gregonis could have planted cooper's blood at any point in 3-5 days prior to Blake showing up.....or the degraded size and shape of the sample/random fluctuations was enough to bamboozle Dr. Blake

I've noticed that the blue shirt, the blood on three seats, the fact that Gregonis checked A-41 out and opened it despite saying he didn't never gets addressed by guilters. They just fling poo and come up with absurd conspiracy theories. None of Fletcher or Kristof's points have REALLY been rebutted (except for the fact the blood vial had only Kevin's blood but even that doesn't change that a.) the vial was still empty, which is bizarre and b.) the card still had two people's blood in it)

You sir are a complete and total hack.
Josh never changed his story and never said there was “3 white guys”. Funny how you don’t mention that Kevin raped a woman on a boat when he was on his little trip down to Mexico. Kevin’s blood was found at the crime scene along with prints from his prison issued shoes, the tan shirt had Kevin’s blood and the victims blood on it, his dna was found on cigarette butts in the car he stole from the Ryan’s. The multiple dna tests they’ve done has directly linked Kevin Cooper to the murders and has further proven he is guilty. Your disturbing and weird animation is a slap in the face of this horrific crime and the family that was murdered by Kevin Cooper.

Kevin Cooper has movie stars and Jesse Jackson holding rallies for him, people carrying signs, lighting candles, saying prayers. To them and you I say:

I was 8 when he slit my throat,
It was dark and I couldn't see.

Through the night and day I laid there,
trying to get up and flee.

He killed my mother, father, sister, friend,
And started stalking me.

I try to run and flee from him but cannot get away,
While he demands petitions and claims, some fresh absurdity.

Justice has no ear for me nor cares about my plight,
while crowds pray for the killer and light candles in the night.

To those who long for justice and love truth which sets men free, When you pray your prayers tonight, please remember me.
- Josh Ryan

I notice that the people who think Cooper did it just flat out lie and ignore glaring holes.
Gregonis has been credibly accused of forging evidence in other cases, and he would have had at least enough practical experience to know that adding a few nanoliters of Cooper's blood to A-41 would likely obscure any original enzymes to the point even Dr. Blake would be fooled. In many ways it would have been disgustingly easy (just use a capillary tube) since Gregonis had 5 years practical experience despite gaps in his knowledge, and he would have also had an opening (Blake didn't arrive in the lab until October 3rd, a monday. He'd need to arrange travel time, so it's possible Gregonis got the results on Wednesday the 28th or Thursday the 29th.....meaning he would have had those days, Friday the 30th and possibly Sunday the 2nd to pull it off.) Standards were also such that scientists (even brilliant ones) would often give the benefit of the doubt despite clear improbabilities. So yeah, it would have been QUITE doable to plant Cooper's blood on A-41 without changing the overall volume and appearance, and Gregonis's willingness to forge evidence in the Bill Richards case show he absolutely was enough of a shithead that he'd do so without question (the department as a whole was also filthier then a pig in shit.)

Even if was assume that A-41 went through no tampering it would have (between June 6th and October 3rd) been depleted from a 1/4 inch wide and elongated drop to around 200 nanoliters spread across a few thin smears of blood on various paint flakes.....and would have gone through AT LEAST 5 freeze thaw cycles during all of this. It would have also a.) been left in a hallway for 24 hours prior to collection b.) collected by gouging chips out of the will and c.) gone through about 3 extended freeze periods (between the third freeze and third thaw it was 15 days, between the fourth freeze and fourth thaw it was 35 days, and, assuming no tampering, 60 days between the fifth freezing and fifth thaw). The chances of even hardy enzymes like transferrin being readable at that point are laughably tiny, and yet Dr. Blake didn't see any ambiguities at all (which is odd given that he tended to not make definitive calls if there were ambiguities). In that light adding a few nanoliters of cooper's blood actually makes sense, since even a tiny amount of fresher blood will likely dominate the electrophoresis process compared to a degraded blood sample

I notice that the comments of those who think Cooper did it don't really address the following points:

1.) Blue Shirt: Like it or not this unambiguously existed no ifs ands or buts. The log mentioning it was only ever filled out if someone called the department to get them to send someone, and since the shirt at trial was found by an officer there would be no practical reason to use the dispatch log for it. Moreover, the shirt in the log is not only said to be a different color from the tan shirt, it was said to be found on a different day in a different location on a different side of the road. And while the memory of Laurel Epler (who the log reports as having found it) 21 years later was somewhat foggy, the log made AT THE TIME not only said that she reported the shirt as blue, they also said EVIDENCE PICKED UP. So there was a blue shirt with possible blood found that was never turned over, no ifs ands or buts about it.

When Josh initially described multiple attackers he said one had a blue shirt on, and one of the men in the bar might have had a blue shirt on too.

2.) Blood on three seats of the car: The state claimed that Cooper washed himself off in the shower of his hideout before driving away....which would make it impossible for there to be blood on three seats. Even if we assume that he didn't wash off in the shower there are some other gaping holes; firstly, THREE people who saw the car that night either identified a WHITE driver or multiple occupants of the car. Since these accounts were made BEFORE Cooper was a suspect they're untainted and thus more accurate than any later recollections. One of these people was their neighbor and the likelihood she'd mistake a 25 year old black guy who was 5'7 for a 41 year old and 6'2 white man she knew personally is.....well bullshit. Secondly, the ONLY reason Cooper would have gone to Long Beach was to seek out a possible acquaintance, Herbert Gordon Mims. Otherwise Cooper had absolutely no ties to Long Beach and no reason to go there instead of to San Ysidro (and if he went to San Ysidro getting a friend from LA to come down and pick it up would be a logistical nightmare considering this was all pre cellphones). If Cooper had sought out Mims....wouldn't he have knocked on the door and rested inside rather then waiting

3.) Donald Gamundoy's testimony: Gamundoy was the VERY first person to speak to Josh about what happened and ask questions, and he got pretty accurate answers for basic questions when he used a communication board (Josh was able to accurately give his name, address and phone number) while the staff said he was at the highest alertness setting possible for a trauma patient. Gamundoy was often mistaken for being Hispanic (he's Hawaiin) and so he not only asked if there were multiple attackers he asked "did they look like me?" Josh pointed to NO on the board, but to YES when asked if they were white.

That pretty much proves that the "he was confusing three Mexicans who came by looking for work" is a lie after the fact. In his earliest (and thus most untainted memories) Josh not only indicated three people, he said they were NOT Mexican in the slightest (or at the very least they weren't obviously Dark Skinned Mexicans). It was only when Dale Sharp used an inept hand squeeze system that Josh started to get confused. Either way, Josh's earliest memories show that he thought there were three WHITE male attackers.

4.) Button and sheathe: First of all, the report made the day Cooper escaped (before the murders even happened) stated he was wearing a BROWN jacket, while the button was from a GREEN Jacket. Moreover, the fingerprints of Officer Steven Moran were found in the closet where Cooper had his sleeping nest, despite his claims he never entered. It was also determined (based on when the prints were pulled on June 8th) that the ONLY time he could have left those prints was on June 6th......the same day he supposedly didn't see anything. So either Moran was blind as a bat and didn't see the stuff lying on the floor.....or he put it there afterwards.

5.) Cigarettes in the Car: Again, this one doesn't really hold up. While the initial report mentions OTHER cigarettes were found in the ashtray (and which mysteriously vanish into the ether afterwards) the two cigarettes (V-12 and V-17) don't get a mention. And considering that other tiny items (like electric tape and punctures) were in the same location as the cigarettes and noted, the odds of them not being noticed are small. More importantly, V-12 and V-17 only appear AFTER multiple cigarettes from Cooper's hideout failed to be processed into evidence....and the same officers who "found" V-12 and V-17 were the same guys who lost those cigarettes. Mechanically, taking a few cigarettes from Cooper's hideout and dumping them in the car (while getting rid of the cigarettes already in the ashtray) would be pathetically easy and not at ALL difficult to pull off, so the only reason to dispute this is a puppyish belief the cops wouldn't do that.

6

The only thing keeping me from unreservedly declaring Cooper innocent is that the transferrin results (when looked at on the plate) supposedly matched Cooper and was rare. From what I read it may have been possible (albeit somewhat difficult) to plant Cooper's blood on A-41 so that his transferrin would overshadow the original transferrin. Gregonis's 5 years practical experience meant it would have conceivably been within his capabilities to pull it off without being noticed as long as he had a microcapillary tube, a microscope, glass slides and the air conditioner on, and Gregonis was definitely enough of a corrupt snake that he WOULD have done it if he felt there was a need to do so. The pressure of the case means he might well have (and the fact he did lie under oath about not opening A-41's glassine envelope just makes the doubt bigger....well that and the blue shirt.)

Regrettably the only way to know for certain is to review all the undisclosed documents in the state's possession. If a review finds that such a thing weren't possible with the capabilities of the day then Cooper is guilty; if it shows that such a thing were possible then the other evidence means he likely didn't do it.

Note: this would involve knowing exactly what equipment was in the lab at the time, as well as protocols. Theoretically a micro capillary tube could have been used to gather a tiny amount (1-20 nanoliters) and distribute it. If Gregonis lied about how much he used in testing (very possible given all the other lies he's told) it's possible that even after early August there was either no blood left or not enough to test....which would mean Gregonis would just need to generate a 1,000 nanoliter blood drop, let most of it evaporate under a microscope until it was small enough (100-200 nanoliters) and add it to the paint chips. The same method could have also worked even with existing smears (just let it evaporate to 1-20 nanoliters THEN collect).

The one thing that is clear is that there was misconduct and incompetence. Even if Cooper did it the sentence should be commuted to life in prison just on that.

All told this is a good video even if the animation is weird at times; it does sum up the oddities and the fact that the people commenting just to say Kevin did it do nothing but fling shit or make emotional appeals is telling

Read Judge William Fletcher's dissent; it goes into detail about the EDTA testing and how the Judge was a biased moron

there's hard evidence A-41 was tampered with; Gregonis checked it out for 24 hours without telling the defense even though he was supposedly just verifying it could be tested; while he denied opening it his initials AND the date he returned it were on it (which pretty much proves he DID open it because lab procedure is that you NEVER initial and date a container unless you open it) and his stated purpose means that what he testified to doing (looking through the glassine to verify the pillbox) would not have worked. So no, Gregonis lied under oath about not opening A-41 no ifs ands or buts about it and the only reasons are a.) he planted Cooper's blood or b.) He fucked up so badly the DNA was worthless. Given that he kept the evidence out for 24 hours and the other items like the blue shirt option a is the only logical choice.

Wait how did Kevin make phone calls from an Abandoned house?? There were NO cell phones in 80s I mean where the Hell did he get access to a phone in the abandoned house?? After escaping prison it didn't mention him going to use a payphone? Strange

For those who keep insisting that Cooper is guilty and that this video is just misinformation.....None of what is said is wrong:

1.) Dispatch logs show that there was a second shirt found; since dispatch logs are only ever filled out if someone calls the department to request collection the tan shirt at trial wouldn't have been mentioned since it was found by an officer during an official search. The shirt in the logs was also said to be a different color AND to have been found on a different day. And while the woman who found the shirt in the first place had a foggy memory 21 years later, the log made AT THE TIME not only said she reported the shirt as blue but said "evidence picked up" without contradicting her.

A blue shirt with possible blood was found near the canyon corral bar, no ifs ands or buts about it. That the only response the state can give is "nu uh" shows that they have no leg to stand on.

2.) Blood on three seats: The state has consistently claimed Cooper washed himself off in the shower before driving away. If that's the case, how the hell did he leave blood on three seats? A small cut is not going to be able to leave blood on the driver seat, backseat, passenger seat, AND passenger floor compartment. Now, the fact that the shower had luminol on the floor or around the drain implies there was no washing off at all, but that just raises the question why none of the three people who reported seeing the car in the first few days uniformly described multiple occupants or a white driver.

3.) Button: Again, the records clearly show that Cooper was wearing a BROWN jacket, not a green one. Moreover, the fact that Officer Moran's fingerprints were found in the closet when he swore he never entered it, and that the only time he could have left them was on June 6th (i.e. the same day he reported nothing) are also in the trial transcripts. None of this has ever been rebutted by the state no matter how hard they try. Whether Cooper did it or not, that button was planted. The rope was also likely planted; Kathy Bilbia said the ropes were kept in the breeding area of the ranch rather then in the house, and the nature of the attack (a blitz attack lasting at MOST 4 minutes) means that a rope wouldn't have been used. Even the blood on that was only ever found to be type A....which is a pretty large chunk of the population.

4.) Hatchet: Again, this was found on the passenger side of the road; the car was moving at high speed earlier on the road, so it would have been easier to chuck i

5.) Cigarettes: While the initial inventory mentioned OTHER cigarettes in the Ashtray, the two cigarettes later tied to Cooper (V-12 and V-17) flat out don't get mentioned. Curiously, the report that first mentions V-12 and V-17 does NOT mention the ashtray cigarettes despite them having been in plain sight (and far more visible then V-12 and V-17 would have been).

6.) A-41: Dan Gregonis DID in fact go back to change his results on A-41 when he realized they excluded Cooper; more accurately he misread Cooper's EAP enzyme as type B and declared that A-41 was also type B. When he learned Cooper was an rB he changed A-41 so that it would match Cooper's EAP (as well as updating Kevin's profile). He literally admitted during trial that he only did it after realizing his initial results would clear Cooper, and the fact he was trying to get verification a week before the trial shows that he wasn't acting in good faith

7.) Don Gamundoy: He DID testify that Josh denied the attackers were mexican or black. This isn't conjecture. He literally said that according to Josh the attackers were white. Whether you believe Josh's recollection was accurate he DID Tell that to Gamundoy, and the only response is to pretend he never exist

One thing the video forgot to include; A-41 was checked out for 24 hours without the defense being told. While the criminalist denied opening it during those 24 hours he initialed and dated the seal, which you ONLY do when you open it. Either Gregonis forgot basic protocol or he lied under oath, there's no middle ground. Pretty much every response from people who think Cooper did it is to a.) lie (Alan Keel tried to claim the photo was of the outer bag and ignored it clearly shows a small envelope with A-41 on it) b.) downplay (the investigation claimed Gregonis dating and initialing it doesn't PROVE he opened it....even though it actually does according to lab protocol) or c.) ignore it entirely. That this is all they can do shows they kind of know it's a weak argument

Cooper is an example of someone who was NOT a nice person (I believe he raped both Lori Stahl and Deborah Englehart) but was likely innocent of the crime for which he was sentenced to die. Someone can be a complete asshole and still be accused of something they didn't do, and given the dodgy dna testing and the blue shirt the idea that cooper did it is....laughable to say the least. At the very least he didn't get a fair trial so if he just spends the rest of his life in stockton that would be acceptable if he truly is guilty

At this point the only thing the state really has left is pretrial serology, and if Gregonis had certain equipment even THAT could have been manipulated. About 6 serology markers are probably legitimate but those ones are dirt common to the point 41 MILLION people in the country likely had those same six enzymes. The others are

Peptidase A: Gregonis knew 2 weeks in advance Cooper had a rare Peptidase A type, and Dr. Blake was only ever going to see a photograph rather then the actual plate. Photos are generally piss poor substitutes for actually seeing it so if Gregonis fucked with the testing process (either during the testing or even just manipulating the staining during the closing he could have bullshat Dr. Blake.)

Transferrin: Dr. Blake only got to look at the plate 2 months after Gregonis actually got Cooper's blood. If Gregonis had precision syringes or a Gilson Pipetman pipette, he could have generated a drop in the 200-500 nanoliter range, and combined it with things like minutien pins or microcapillary tubes to flat out replace the original blood in A-41 with Cooper's. There wasn't much blood left in the pillbox by September 28th or so (when Gregonis learned Cooper had a rare transferrin), minutien pins and microcapillary tubes would be quite easy for a five year veteran to use as long as the overall amount of blood in the liquid was tiny enough.) Moreover, they'd been publicly committed for months due to both the nature of the case and the racial elements. If anything excluded Cooper while the defense was watching, they faced at best massive embarrassment and at worst possible ruin. So in that situation even something as radical as replacing the tiny thin smears of blood in the original pillbox with the suspect's actually makes perverse sense when you're that desperate.

Haptoglobin: Same issue as the Transferrin. Notably Gregonis tried to call it DESPITE the fact there was a sample well spillage.

Gc: Same as Transferrin and Haptoglobin. In addition the Gc was inconclusive and couldn't be called at the time

EAP: Gregonis initially called this as a type B and was pretty adamant. It was only AFTER he learned Cooper was rB that he changed it; he claimed he made the change after getting feedback from others, but he also admitted that he made the change after and as little as 1 week before trial began he asked for help determining the EAP through an isoelectric plate. This implies that he only made the change to cover his own rear.

Notably the Peptidase A Transferrin and Haptoglobin were the only TRULY unique enzymes in Cooper's profile, with his EAP being somewhat rarer then many.

In terms of character Gregonis ABSOLUTELY was corrupt enough that he would have that (Just ask Bill Richards), there was a desperate need to tie A-41 to Cooper because they'd already publicly committed, and the department as a whole was racist corrupt and inept.

The only issue is whether it was physically doable and as long as he had a precision syringes and flame pressed microcapillary tubes/minutien pins yeah it was doable.

One thing they left out that helps Cooper; Gregonis initialed and dated the seal of the bindle holding a-41 when he checked it out. Per protocol you NEVER do that unless you open it....but Dan Gregonis denied opening it. So either he forgot the most basic rule or he lied. No middle ground there

Edit: To elaborate. Basically you initial and date an outer container when you open it to examine the contents. It maintains custody. If Gregonis had just felt the bindle and looked through it like he claimed there would be no need to initial and date the bindle because the envelope holding the bindle was itself initialed and dated. And yet he did.
