LOS ANGELES — Autopsy reports rarely come with barbed comments. So eyebrows rose when the autopsy results of 14-year-old Celeste Rivas Hernandez were released with a statement from the Los Angeles County chief medical examiner saying it was “unfathomable” her grieving parents had to wait months to learn how their daughter died.
The autopsy performed on the dismembered body found in a Tesla in the Hollywood Hills had been sealed by a court order in the investigation that led to murder charges for singer D4vd. Dr. Odey Ukpo’s comment with the report was his most pointed effort yet to emphasize his office’s independence from police and prosecutors, as well as his desire to make as much death information public as soon as possible.
D4vd, who has pleaded not guilty, this week faces a crucial preliminary hearing to determine whether there is enough evidence for a trial. Ukpo’s agency, which determined Rivas Hernandez died from stab wounds, plays a major role, as it has in other prominent cases, including following the death of “Friends” star Matthew Perry and the killings of director Rob Reiner and his wife, photographer Michele Singer Reiner.
Ukpo, 46, sat for a recent interview with The Associated Press in the building where he performed autopsies for nearly a decade before getting the head role in 2023. He has always welcomed the celebrity cases that Los Angeles brings, saying the scrutiny they receive and the likelihood of misinformation spreading are strong incentives to do careful, irrefutable work. And they provide an opportunity to show what his office does and what kind of dangers the community may face.
“I should be able to anticipate the strongest arguments or the most interesting questions by the work that I’ve done,” he said. “If I haven’t, then something’s missing.”
“Life is complicated, but death is simple,” Ukpo said.
Ukpo doesn’t believe sealing autopsy reports helps police investigations, including in the killing of Celeste.
“That goes completely against our mission,” he said. “It’s so important for us to release the information that she did not die from something natural, she did not die from drugs, she was stabbed. And then we start to look back at what made her vulnerable to be in that situation.”
A court-ordered security hold still seals the Reiner autopsies. Authorities said immediately after their deaths that they had been stabbed by their son, who has pleaded not guilty, but little information has followed. Ukpo said he would discuss the findings — if he was allowed.
“The Reiners’ case is one that’s straightforward,” he said. “It’s unclear to me what sort of information we have that would ruin the case.”
Sometimes there is no good reason for secrecy, he said.
“People say: ‘Why would they get the information out there? Because then the case is just going to go awry.’ But awry? How? What information?” he said, adding: “The killer knows what they did.”
The LA County Sheriff’s Department said in a statement that security holds “are rarely requested and are carefully reviewed on a case-by-case basis to determine whether temporarily withholding the autopsy report is necessary to preserve sensitive investigative information.” It said the reports can contain details “that only the person responsible would know,” meaning detectives can use that knowledge to assess the credibility of witness statements and uncover false confessions.
The Los Angeles Police Department, which handled the D4vd and Reiner cases, did not respond to a request for comment, and the district attorney’s office declined comment.
Ukpo was appointed chief medical examiner-coroner in 2023, becoming the agency’s first Black leader since it was founded in 1850. His staff responds to about 13,000 sudden, unexpected and premature deaths per year.
The “coroner” part of his title was dropped soon after his appointment and Ukpo supported that change, saying a coroner is usually an elected official — often also the county sheriff — but not a doctor.
“’Coroner’ just kind of confused our purpose and suggested that we were within a law enforcement agency,” Ukpo said. “It’s so important to establish our independence.”
Andrew Bernstein, a longtime New York criminal defense attorney who is not involved in any of Ukpo’s cases, said “buddy-buddy” relationships can easily develop between medical examiners and law enforcement.
“They’re dealing with the cops all the time,” he said. “They’re using the same language.”
That relationship can hurt a prosecutor’s case, he said, because “jurors pick up on that all the time” and may perceive a testifying medical examiner as biased.
But, Bernstein said, “you don’t want so much independence” that the medical examiner makes decisions regardless of the wants and needs of police and prosecutors.
“You don’t want a rock star chief medical examiner,” he said.
At age 6, Ukpo — who grew up in Anaheim not far from Disneyland — had wanted to be a homicide detective.
But when he met his family physician, he “thought it was really cool how he would work with his hands, do dirty work, work with blood” but “could be very professional in his office, in a suit, in a tie.”
“There you go, that’s the formula for a forensic pathologist,” he said.
Very few medical students want to make autopsies their life’s work. He said with a laugh that declaring his intentions “made for interesting medical school interviews.”
His education included stints at Loyola University in Chicago, at the Mayo Clinic in Rochester, Minnesota, and with the medical examiner in Albuquerque, New Mexico.
Ukpo performed autopsies on rapper Mac Miller, actor Tommy Lister Jr., and model and actor Kim Porter, the former longtime partner of Sean “Diddy” Combs.
Perry died within months of Ukpo getting the top job, and his office determined the primary cause of death was acute ketamine toxicity.
“Matthew Perry was really an important one to notify people that ketamine is not harmless,” he said.
He said this and all his work is driven by his desire to first and foremost serve the public.
“What I’m trying to shift during my leadership here is to try to focus on community first,” he said. “Death doesn’t just happen for the family, for the individual. When a death happens, it reverberates.”
