Kevin Cooper (born Richard Goodman; January 8, 1958)[1] is an American man currently imprisoned at San Quentin State Prison's death row.[2] Cooper was found guilty of four murders in the Chino Hills area of California in 1983.Cooper's conviction has garnered repeated attention from both Nicholas Kristof in the New York Times and Erin Moriarty on the CBS News program "48 Hours."[3] There have been accusations that Cooper received an inadequate defense, as well as prosecutorial misconduct such as destruction of evidence, withholding exculpatory evidence from the defense, planting of evidence, brainwashing to witnesses, and perjured testimony by the Sheriff's Department. There have also been practical questions raised, such as how Cooper, at 155 pounds, and allegedly acting alone, overpowered a 6-foot, 2-inch ex-military policeman and his athletic wife, both of whom had loaded firearms close at hand. It has also been questioned why a single perpetrator would use 3 or 4 different weapons to commit the murders, and why none of the victims were able to run away while the others were being attacked.

Cooper's habeas corpus petitions have been denied. The evidence in the case of the original trial has been reviewed by the California Supreme Court, by the United States District Court and by the Ninth Circuit Court of Appeals.

In 2007, two judges of the United States Court of Appeals for the Ninth Circuit wrote that "As the district court and all state courts, have repeatedly found, evidence of Cooper's guilt was overwhelming. The tests for which he asked to show his innocence 'once and for all' show nothing of the sort." In a concurring opinion, however, Judge Margaret McKeown said she was troubled that the court could not resolve the question of Cooper's guilt "once and for all" and noted that significant evidence bearing on Cooper's culpability has been lost, destroyed or left unpursued. In a lecture, a distinguished federal appeals court judge, William A. Fletcher, declared "the San Bernardino Sheriff's Department framed him".[4]

In a dissenting opinion, written in 2009, Judge Fletcher began by stating: "The State of California may be about to execute an innocent man." Fletcher wrote that the police may have tampered with the evidence and that the Ninth Circuit Court should have reheard the case en banc and should have "ordered the district judge to give Cooper the fair hearing he has never had." Five federal circuit court judges joined in Fletcher's dissent and five more stated that Cooper has never had a fair hearing to determine his innocence.

Early life

Cooper was born Richard Goodman on January 8, 1958, near Pittsburgh, Pennsylvania. When he was two months old, his mother placed him in an orphanage. At the age of six months, he was adopted by Melvin and Esther Cooper, who renamed him Kevin Cooper. As a child, Kevin Cooper was subjected to physical abuse and ran away from home numerous times. As an adolescent, he was sent to juvenile custody numerous times.[1]

Previous criminal record

Cooper had a criminal past that included theft and burglary. He was sentenced to a one-to-two-year prison term in 1977 for burglarizing a home in Pittsburgh, Pennsylvania. Cooper was never tried but later stipulated to kidnapping and raping a minor female who interrupted him during a burglary in Pennsylvania.[5] Cooper agreed to the stipulation on the advice of his lawyer who mistakenly believed this admission would help Cooper avoid the death penalty in the Chino Hills case.[5] During the purported crime, he threatened to kill the teen-age victim.[6] Over the next five years, he was convicted and sentenced to jail twice for burglaries and was released on probation in 1982.[7] He escaped from custodial settings in Pennsylvania 11 times.[5] In late 1982, Cooper fled to California after escaping from a Pennsylvania psychiatric facility.[8] In California, Cooper was soon convicted of two burglaries in the Los Angeles area. He began serving a four-year sentence under the alias David Trautman[9] at the California Institution for Men (CIM) in Chino on April 29, 1983, where he was assigned to the minimum security section.[10] On June 2, 1983, Cooper climbed through a hole in the prison fence[11] and walked away from the prison across an open field.[11] [12]

Chino Hills murders and arrest

On the morning of June 5, 1983, Bill Hughes arrived at a semi-rural home in Chino Hills, California, where his 11-year-old son Christopher had spent the night. Inside, he found Douglas and Peggy Ryen, their 10-year-old daughter Jessica and his own son dead. They had been chopped with a hatchet, sliced with a knife, and stabbed with an ice-pick. Josh Ryen, the 8-year-old son of Douglas and Peggy, had survived. His throat had been cut. Mrs. Ryen's purse was in plain sight on the kitchen counter, but no money had been taken. The family station wagon was gone; it was discovered several days later in Long Beach, California, about 50 miles southwest of Chino Hills.

The San Bernardino County Sheriff's Department deputies who responded to the call identified Kevin Cooper as the likely killer. He had admittedly hidden out in the vacant house next door, the Lease house, 125 yards away, for two days. He had made repeated calls from this house to two female friends asking for money to help with his escape, but they had refused. Cooper testified at trial that he had left that house as soon as it got dark on June 4 and had hitchhiked to Mexico. It was established that Cooper checked into a hotel in Tijuana, about 130 miles south of Chino Hills, at 4:30 pm on June 5.

There, Cooper befriended an American couple who owned a sailboat. He hitched a ride on the boat with them as a crew member cruising the Baja and Southern California coasts.

Seven weeks later, while still staying on the couple's boat, Cooper was accused of raping a woman at knifepoint on a boat docked nearby.[13] While visiting the sheriff's office to report the crime, the rape victim saw a wanted poster with Cooper's photograph and identified him as the rapist. Deputies and coast guard personnel detained him as he tried to swim ashore.[14] Cooper was never charged with rape or assault in this matter.

Evidence

There is disagreement about Cooper's guilt and the evidence supporting it.[15] The evidence used to convict Cooper includes the following.

Trial

On Cooper's motion, the court changed the venue of the trial from San Bernardino County to San Diego County. Cooper pleaded guilty to the charge of escape from prison.[9]

In videotaped testimony, Josh Ryen said that the evening before the murders, just before the family left for the Blade barbecue, three Mexican men came to the Ryen home looking for work. Ryen did not identify the killer, but said in an audiotape with his treating psychiatrist that he saw the back of a single man attacking his mother. Ryen told a sheriff he thought three men had done it because "I thought it was them. And, you know, like they stopped up that night," but he did not actually see three people during the incident.[9]

Cooper testified in his own defense. He admitted escaping from CIM, hiding out and sleeping at the Lease house, but denied committing the murders or being in the Ryen house. Cooper said he left the Lease house on foot, hitchhiked, stole a purse, and eventually made his way to Mexico. The defense pointed out the inconsistencies in Ryen's testimony, presented evidence of other events apparently not involving Cooper that might have had something to do with the killings, and presented an expert witness that criticized the forensic investigation.[9]

A jury convicted Cooper of four counts of first degree murder and one count of attempted murder with the intentional infliction of great bodily injury, and then imposed the death penalty.[9]

During the penalty phase of Cooper's trial, a stipulation was entered that “Kevin Cooper was the man who abducted (the female minor) on October 8th of 1982 from the Heath residence, kidnapped her, and later raped her in Frock Park."[5] Cooper agreed to the stipulation on the advice of his lawyer who mistakenly believed this admission would help Cooper avoid the death penalty in this case.

Possible manipulation of evidence

Cooper has consistently denied any involvement in the crimes for almost 30 years. Some arguments supporting his innocence include:

An alternate suspect

Over the years, the defense has raised the possibility that a man named Lee Furrow (who had previously murdered Mary Sue Kitts on behalf of Clarence Ray Allen) was the actual killer.

Arguments in favor of the alternate suspect theory

Arguments against the alternate suspect theory

According to the Ninth Circuit, Roper's allegations “lack credibility.” Roper was abusing drugs and hallucinating the night she says she saw Furrow.[34] She also had a motive to disparage Furrow because he left her on the night of the murders and began a sexual relationship with her childhood friend.

Furrow provided his DNA for testing.[35] A law firm appointed by the governor of California to review the case concluded that no DNA evidence points to any person other than Kevin Cooper.[36]

Post-trial DNA testing

In 2001, Cooper became the first death row inmate in California to successfully request post-conviction DNA testing of evidence. The results of those DNA tests failed to exonerate him of the 1983 murders and indicated (1) Cooper's DNA was present both at the crime scene and in the stolen station wagon, (2) hairs found on three of the victims were likely their own, and (3) no DNA belonging to other assailants was present.[5] [37]

Blood testing

DNA testing confirmed that Cooper's blood was at the crime scene.[5] However, it was later found that a blood vial containing Cooper's blood possibly contained a second individual's blood; Judge Huff would block any attempt to pursue the matter during the hearings and the vial itself would later be found empty when the defense won the right to retest it in 2019. More importantly, prosecution expert Daniel Gregonis had checked Cooper's blood out for 24 hours without informing Cooper's attorneys (alongside his saliva and the bloodstain recovered from the house). This is significant because of two key pieces of evidence that relied on blood from Cooper:

EDTA testing

After the blood test results came back supporting Cooper's guilt he claimed that the blood had been planted and asked that the T-shirt be tested for presence of EDTA, a preservative. High levels of EDTA would show that the blood came from a vial rather than directly from Cooper.[41] The EDTA testing was conducted by Cooper's chosen expert Dr. Ballard but failed to show elevated levels of EDTA.[42] While Judge Huff would claim that the blood stain had levels of EDTA lower than most controls on the T-shirt and “dramatically lower than the level of EDTA expected in a tampering scenario involving blood from a purple-topped tube", Judge William Fletcher pointed to DNA testing done by the state's expert Terry Lee as proof that the controls actually had DNA in them and were thus not legitimate controls at all. He also used a graph to argue that the EDTA corresponded with the DNA in each of the stains and accused Judge Huff of intentionally sabotaging the tests against Cooper.[17] Additional testing by Dr. Gary Suizdak on ten specimens[43] found significant levels of EDTA. However, according to both Suizdak and the state's expert Dr. Terry Lee, the samples were most likely contaminated by EDTA present in Suizdak's lab.[44] This claim has been disputed, and when Cooper's attorneys asked to see Dr. Siuzdak's notes to verify the claim they were denied access by Judge Huff.[17]

Hair testing

According to Dr. Terry Melton, the hairs obtained from Jessica Ryen's hand were either animal hairs or human hairs that came from herself or someone maternally related to her. Other hairs selected by Cooper's expert Dr. Peter DeForest came from domestic dogs.[45] Nevertheless, Judge Huff had also limited testing to hair without Antigen roots, essentially guaranteeing a negative result.

Cigarette testing

When Cooper's hideout was searched multiple cigarettes were not processed into evidence. Officers Craig Ogino and David Stockwell (the officers who processed the hideout) were also the officers who discovered the cigarettes later tied to Cooper in the car. One of the cigarettes (V-12) was also listed as consumed prior to the trial. According to Dr Ed Blake's notes the Cigarettes were 4 mm long and yellow in color. When the cigarettes were examined in 2001, they were white and had grown to 7 mm. Notably, when Daniel Gregonis checked out A-41 he also checked out Cooper's saliva as well as a known blood sample.

Assessment by courts, governors and independent groups

California Supreme Court

The Supreme Court of California upheld Cooper's conviction in May 1991.[46]

Cooper was scheduled to be executed on February 10, 2004, but on February 8, 2004, a three judge panel consisting of Judges Pamela Rymer, Ronald Gould and James Browning heard Cooper's petition and rejected it by a vote of 2–1.

Judge Browning, the lone dissenter, was able to assemble enough judges to get an en banc ruling blocking the execution to allow further DNA testing. Ultimately, the US Supreme Court unanimously upheld the stay, effectively making it impossible to carry out the death warrant.

The postponement followed a campaign by various groups in the Bay Area and around the country, such as the Campaign to End the Death Penalty, the ACLU, Death Penalty Focus and The Mobilization to Free Mumia Abu-Jamal.

Denial of clemency by California Governor Schwarzenegger

On January 30, 2004, the office of Governor of California Arnold Schwarzenegger issued the following statement regarding his decision not to grant clemency to Kevin Cooper:

On December 17, 2010, Cooper filed a second clemency petition to Governor Schwarzenegger. This petition laid out new developments in the evidence that were not known when the first one was denied in 2004.[47] The second clemency petition also cited the conclusions and observations of twelve appellate judges of the Ninth Circuit Court of Appeals, including the fact that blood taken from Cooper after he was arrested was contaminated with the DNA of another person,[48] that a sheriff's deputy had lied at Cooper's trial about destruction of key evidence,[49] and that three witnesses, never interviewed by the prosecution, had come forward with strong evidence of other possible perpetrators.[50] Just before Governor Schwarzenegger left office in January 2011, his office wrote a letter to Cooper's lawyer stating that the application "raises many evidentiary concerns which deserve a thorough and careful review of voluminous records."[51] The letter further stated that since the Governor had only two weeks left in office, he had decided to leave the matter for Governor-elect Jerry Brown's determination.

U.S. Ninth Circuit Court and U.S Supreme Court deny appeals

Cooper has filed multiple appeals and applications for a writ of habeas corpus, all of which have been denied. On December 4, 2007, the Ninth Circuit Court of Appeals denied Cooper's third federal petition for a writ of habeas corpus. The panel concluded: "As the district court, and all state courts, have repeatedly found, evidence of Cooper's guilt was overwhelming. The tests that he asked for to show his innocence 'once and for all' show nothing of the sort."[52] While Judge McKeown concurred, she expressed doubts about the certainty of Cooper's guilt, saying that critical evidence had been lost due to mishandling by the investigators.

On May 11, 2009, the Ninth Circuit denied Cooper's request for a rehearing en banc of the 2007 panel decision. Four judges (Fletcher, Wardlaw, Fisher, and Reinhardt) filed dissents, indicating that they disagreed with the decision. Judge Fletcher stated that there was a strong likelihood that the police tampered with the evidence and accused Judge Huff of deliberately ignoring the Court's instructions to perform proper testing, while Judge Wardlaw stated "as far as due process is concerned 25 years of flawed proceedings are as good as no proceedings at all." Eleven judges joined the dissents (fourteen votes were required to grant the request for a rehearing), though Judge Stephen Reinhardt hinted that the gap may have been closer.[17] Judge Rymer, who authored the original panel decision, filed a concurrence defending both the original decision and the decision to deny an en banc hearing.

Cooper's petition for certiorari to the United States Supreme Court was denied on November 30, 2009.

Inter-American Commission on Human Rights recommends a review

In April 2011 Cooper filed a petition with the Inter-American Commission on Human Rights (IACHR) alleging that his human rights had been violated in multiple respects by his prosecution, conviction and death sentence. The IACHR concluded that the United States had violated Articles I, II, XVIII and XXVI of the American Declaration of the Rights and Duties of Man. The Commission found eight instances where Cooper's due process rights had been violated, that Cooper had received ineffective assistance of trial counsel, and that there were serious questions about racial discrimination in Cooper's prosecution. The IACHR recommended that Cooper be granted "effective relief, including the review of his trial and sentence."[53]

American Bar Association recommendation for clemency

On Saturday, March 19, 2016, the president of the American Bar Association (ABA), Paulette Brown, submitted a letter to Governor of California Jerry Brown, suggesting that Cooper be granted clemency due to claims of racial bias, police misconduct, evidence tampering and poor-quality defense counsel. "We recommend that this investigation include testing of forensic evidence still available to be analyzed to put to rest the questions that continue to plague his death sentence. This is the only course of action that can ensure that Mr. Cooper receives due process and the protection of his rights under the Constitution," Ms. Brown wrote.[54]

New DNA testing order by California Governor Brown

In May 2018, Nicholas Kristof wrote an article in The New York Times highlighting the case, arguing that the truth could be determined by doing advanced testing on the bloodstained t-shirt, the hatchet handle and the hand towel used by the murderer and including diagrams showing both that Lee Furrow's stepmother lived close to where the victim's car was recovered and that Officer Steven Moran most likely planted evidence to frame Cooper. Soon afterward, Kamala Harris (who refused to allow the testing when she was the Attorney General of California[55]) and Dianne Feinstein both publicly called for advanced DNA testing. In response, DA Michael Ramos submitted a response to Cooper's petition, calling for the petition to be refused. Ramos would also file to have Cooper executed following his failed attempt to be re-elected.

On July 3, California Governor Jerry Brown hinted that he might be willing to approve DNA testing, sending Cooper's attorneys a list of questions. On August 17, the defense submitted their response, revealing that they had managed to acquire Lee Furrow's DNA for testing. On October 6, Nick Kristof wrote a follow-up in which he reported that Lee Furrow had told him that he was now open for testing to "clear his name."

In December 2018, outgoing Gov. Brown ordered new DNA testing in the Cooper case.[56] The testing has since been revealed; insufficient DNA was recovered from the shirt but a profile that was neither Cooper or Furrow was recovered from a hand towel taken from the victim's house. While Vial VV-2 only had Cooper's profile, it was also found drained of blood save for residue at the bottom, which was described as "unusual" by DNA expert Bicka Barlow.

Independent investigation order by California Governor Newsom

On May 28, 2021, governor Gavin Newsom signed an executive order appointing the law firm Morrison & Foerster[57] to "launch an independent investigation of death row inmate Kevin Cooper’s case as part of the evaluation of Cooper’s application for clemency. The investigation will review trial and appellate records in the case, the facts underlying the conviction and all available evidence, including the results of the recently conducted DNA tests previously ordered by the Governor to examine additional evidence in the case using the latest, most scientifically reliable forensic testing."[58] The investigation would ultimately reject Cooper's claim, but acknowledged that it had not fully evaluated claims of prosecutorial and law enforcement misconduct "except in instances in which they determined that they were relevant to Cooper's claim of innocence." The investigation also acknowledged that it had not evaluated claims that Cooper's trial and the verdict had been influenced by racial prejudice, and also failed to examine previously undisclosed documents. Cooper's attorneys responded the following day, arguing that the investigation was "demonstrably incomplete" and that the investigators had "failed to follow the basic steps taken by all innocence investigations that have led to so many exonerations of the wrongfully convicted."[59]

Cooper's attorneys would release another response to the Special Counsel on October 26, 2023, claiming that the investigation had been fatally compromised by only reviewing prosecution documents that had been presented at trial despite Morrison Foerster having earlier requested all documents in the prosecution's possession. They also argued that Alan Keel (the DNA expert used by Morrison Foerster to assess the evidence) was unreliable due to having professional ties with both Daniel Gregonis (who was accused of forging evidence) and Ed Blake (who had been involved in the 2002 DNA testing and disputed the idea tampering occurred), alleged misconduct in the Jane Dorotik case (Dorotik was exonerated in 2022), and perceived scientific errors in made in his assessment (Keel tried to guess a sample's age based on how degraded it was even though the rate of degradation depends on environmental factors like heat, light and moisture).[60]

On December 14, 2023, ABA President Mary Smith would write a letter to the Governor urging further investigation, arguing that that the failure to examine the undisclosed documents in the state's possession made it impossible to have confidence in the accuracy of the verdict.[61]
