In late November 1988, 30‑year‑old Deborah “Debe” Atrops disappeared after a hair appointment in Tigard, Oregon. Her estranged husband, Robert “Bob” Atrops, reported her missing. Two days later, police found Debe’s body in the trunk of her car at a construction site near Beaverton. She had been strangled; she was not sexually assaulted. The discovery launched a homicide investigation that ultimately went cold for decades.
Detectives initially focused on Bob. He had reported Debe missing that night, saying she was three hours late returning from an appointment. He called police multiple times that night and later searched the route where she might have driven. Officers who found the car at the scene noticed the license plates were removed and the keys were inside; Debe’s body was in the trunk, positioned as if placed there. Bob consented to a search of the car. Investigators photographed mud on Debe’s coat and shoes and took soil samples from Bob’s driveway and lawn, but early forensic technology was limited and the case stalled.
Debe had left Bob months earlier and was living in Salem. She was dating several men after the separation, including an old boyfriend, Jeff Freeburg, and a man named John Pearson whom she met at work. Friends and family described Debe as warm and fun, but they also said her relationships were sometimes troubled. Some friends recall Debe confiding that she feared Bob and that she worried he would react violently if he discovered she was in another relationship.
Bob’s behavior after Debe’s disappearance attracted suspicion. Some witnesses described him as unusually calm the day police found the car. Detectives questioned inconsistencies in his account of phone calls he said he made the night Debe disappeared—calls that his phone bill did not show. Detectives attempted to place him at pay phones and sought corroborating evidence, but early efforts failed to produce enough to charge him. Bob declined a polygraph and later hired an attorney.
The case lay dormant until a cold case team reopened it in the early 2020s. Advances in forensic science allowed renewed testing. In 2022 the FBI analyzed DNA swabs taken from the collar and shoulder of Debe’s coat, collected in 1988. The results showed a mixture of DNA; John Pearson and Jeff Freeburg were excluded as contributors. The lab said the mixture provided “moderate support” that Bob could not be excluded as a contributor. Investigators also had the car’s tire mud analyzed: the FBI reported the tire mud did not match the site where Debe’s car was found but was indistinguishable from the soil from Bob’s front lawn in composition, color, and texture. Prosecutors viewed those results as supportive of Bob’s involvement.
Detectives re‑interviewed witnesses and Bob himself. In a 2022 interview, Bob gave different explanations for the missing long‑distance calls than he had in 1988, telling investigators he used an MCI calling card from home—something prosecutors say did not fit the facts and would have been illogical if he were frantically searching for his missing wife. Investigators also revisited evidence of their tumultuous marriage: friends told the cold case team Debe had feared Bob and that he had been violent during their relationship.
Prosecutors, led by Senior Deputy District Attorney Allison Brown and attorney Chris Lewman, assembled a case built on contemporaneous investigative leads, the DNA testing of Debe’s coat, the soil analysis linking mud on the car to Bob’s yard, and Bob’s inconsistent statements over the years. They charged Bob with murder; a grand jury indicted him in 2023.
At trial in spring 2025 in Washington County, prosecutors portrayed a pattern of domestic violence, motive linked to jealousy over Debe’s new relationships, and physical evidence placing Bob in contact with Debe near the time of her death. They played interviews and emphasized the DNA on Debe’s coat and the soil match as corroborating evidence. Bob pleaded not guilty and testified through counsel; his daughter, Rhianna Stephens, publicly defended him, describing him as a devoted father and grandfather.
The defense challenged the forensic findings. Attorneys argued the DNA on Debe’s coat was a tiny quantity—about six skin cells—and could represent transfer DNA from normal contact, not proof of strangulation by Bob. They pointed to other men in Debe’s life, especially John Pearson, as having motive and opportunity. Defense investigators noted that semen recovered at Debe’s autopsy matched Pearson, and they highlighted that Pearson had been evasive when contacted by the cold case team. Pearson, who had separated from his wife and had two young boys, was located in Arizona in 2025 shortly before hatched trial dates and took his own life; the defense argued his suicide raised questions about his role and the investigation’s completeness.
Prosecutors disputed those arguments, saying Pearson had been fully interviewed and investigated back in 1988 and found not to be involved; they described his later suicide as unrelated. They urged the jury to view the totality of evidence—motive, means, opportunity, the DNA and soil testing, and Bob’s contradictory accounts—as pointing to Bob’s guilt. They also raised Debe’s own statements in 1988 to friends that she feared Bob might kill her if he found out about her new relationship.
After about six hours of jury deliberation on April 17, 2025, the jury found Robert Elmer Atrops guilty of second‑degree murder. The verdict came 37 years after Debe’s death. Prosecutors called the outcome justice for Debe and her family. At sentencing in July 2025, the judge imposed life with the possibility of parole after 25 years.
Rhianna Stephens, Debe’s daughter, who was eight months old when her mother was killed, maintained her belief in her father’s innocence and read an emotional plea for leniency at sentencing, describing her need for her father in her life. The defense continued to argue that evidence was insufficient to prove guilt beyond a reasonable doubt and emphasized alternative explanations, including Debe’s relationships and the presence of other men in her life.
The case illustrates how cold case investigations can be revived by modern forensics and persistent review of older evidence and testimony, and how decades‑old crimes can produce contested scientific and testimonial disputes in court. It also underscores the enduring pain and complexity for families left behind—Rhianna grew up without her mother and now faces a criminal conviction of the man who raised her—leaving questions and grief that have shaped lives for more than three decades.
