Emberly McLean-Bernard, born six weeks prematurely in rural Mississippi, weighed less than five pounds when doctors sent her home. She didn’t cry and barely ate, her mother said, and it didn’t take two days for her to start breathing. Jocelyn McLean took her daughter to the nearest emergency room, but the baby was already turning blue.
The medical team went straight to coding the blue, pumping air into the baby’s lungs, trying to force an IV line into Emberly’s neck and scalp, pushing her with a rectal thermometer, but her vital signs continued to fail. . After four hours, they surrendered.
A forensic doctor in the state concluded that the death had not been caused by a medical problem, but had been a homicide, the result of “severe injuries with signs of strangulation.”
Ms McLean, a 29-year-old black mother with two other young children, was charged with manslaughter.
Mrs. McLean was surprised. The emergency doctor who had tried to save the baby was shocked. But Dr. Joye Carter, a forensic pathologist selected by the defense to review the case, saw an all-too-familiar pattern: a forensic doctor who made a decision without talking to the doctor or even examining the hospital records. Supervisors who signed their decision. A criminal justice system that too often sends blacks to jail with evidence that may not have convicted anyone else. In court, Ms. McLean and his attorney recalled that Ms. McLean called himself a “monster.”
He spent more than a year in prison before Dr. Carter’s autopsy review forced the forensic doctor and state prosecutor to acknowledge that the baby’s injuries could be explained by desperate attempts to save her. night.
“I am grateful that this woman did not kill her son,” Steven Jubera, Tallahatchie County Assistant District Attorney, said in an interview after the charges were dismissed. “But the other side is, ‘My God, I had a closed wife.'”
The country’s death investigation system, a mosaic of medical examiners, self-employed experts and elected forensic experts who may not have medical training, is responsible for examining suspicious and unexplained deaths. Wrapped in a mantle of scientific authority, their professionals translate the complexities of disease, decomposition, toxicology and physics into simple categories such as accident, homicide or death by natural causes, setting in motion the most serious cases in the legal system. and exerting an enormous influence on the jurors.
However, these experts are far from infallible. As forensic science of all kinds faces scrutiny over its reliability, with patterns of blood splatter, hair coincidence, and even fingerprints that are no longer considered the irrefutable evidence they once were, the science of death has been agitated over the past year with questions about whether forensic work is affected by racial prejudice, preconceived expectations, and the powerful influence of law enforcement.
A study published last year in the Journal of Forensic Sciences found evidence of cognitive bias when 133 forensic scientists received identical medical evidence in hypothetical cases of child deaths. Deaths were more likely to be considered an accident if the child was white and the caregiver was a grandmother; they were most often considered homicides when the child was black and cared for by the mother’s boyfriend.
The study, whose authors included Dr. Carter, touched on the very essence of the slow-moving debate on forensic pathology. He showed, according to its authors, that judgments that should be based on science can be overshadowed by prejudice when medical examiners allow their findings to be affected by information that is not medically relevant. But many leaders in the field insist that forensic doctors are required to consider the entire case before them, including statistics showing that boyfriends are more likely than blood relatives to commit child abuse.
The new investigation was met with an explosive reaction. The National Forensic Association complained that the study had been poorly designed and improperly conducted. A member of the association filed an ethics complaint against Dr. Carter and the other three forensic pathologists listed as perpetrators, alleging that the document would do “incalculable harm to our profession.”
One of the authors suggested that he withdraw from the document simply to end the controversy. “I can’t even sleep at night because of all the hatred and vitriol I’ve received,” he wrote in an email shared with The Times. In frustration, Dr. Carter, who had spent years trying to expand racial representation in the profession, resigned as head of the organization’s diversity committee.
Recent cases such as the death of George Floyd in Minneapolis, where some experts have argued that the prolonged burden of police officers on Mr. Floyd was not the cause of his death, have catapulted the public bias debate. .
Dr. Andrew Baker, the chief forensic doctor in Minneapolis who would perform the official autopsy on the Floyd case, acknowledged in an address to the American Academy of Forensic Sciences in 2015 that “the flagrant flaws in the system they have had tragic consequences for the innocent defendants. “
But he attributed the mistakes to rotten apples in the profession, not the lack of implementation of safeguards against error. “Obvious failures, such as incompetence, dishonesty, fraud and corruption, do not constitute a cognitive bias,” he said.
Dan Simon, a law and psychology professor who served for six years on the federal committee on creating better forensic standards, said forensic doctors have uniquely resisted reforms. “They stand out for their recalcitrance,” he said. “And it’s a serious problem.”
Defective autopsies and erroneous convictions
Critics say reluctance to admit the possibility of bias, combined with a lack of diversity in the profession and a traditionally welcoming relationship with law enforcement, can increase the chances of racial disparities when forensics are wrong. A number of black and Latino defendants have been released in recent years, some on death row, after the autopsy findings that had helped convict them were denied.
In one case in California, Vicente Benavides spent 25 years on death row on charges of raping and sodomizing his girlfriend’s 21-month-old daughter in such a brutal way that he killed her. Mr. Benavides was released in 2018 after experts said the cause of death presented at trial was anatomically impossible.
Prior to her involvement in Emberly’s death in Mississippi, Dr. Carter had spent much of her career dealing with racial prejudice in the forensic profession.
She attended medical school at Howard University, then the only historically black school with a pathology residency, and in 1992 became the first black woman to head a forensic doctor’s office. , in Washington. He noted that there was virtually no channel for training and recruiting non-white people in his profession, although more than half of the homicide victims in the country are black.
He later heard absurd claims from fellow forensics, including that blacks were impervious to pain and that no bruises on dark skin could be detected. He came to believe that the lack of intercultural training was causing mistakes with great consequences.
Some of these ramifications became apparent during her residency in forensic pathology, in the 1980s, when she was the only black pathologist in the forensic doctor’s office in Miami.
A number of poor black women were appearing dead in sad environments: cheap hotels, abandoned buildings, open fields. Although the women found themselves in similar positions, the assistant coroner believed their deaths had been caused by a combination of cocaine use and voluntary sex. Almost all were classified as drug-induced accidents.
Dr. Carter backed away. The victim he examined had a severe crack habit, but Dr. Carter refused to describe the death as an accident.
He was right: after a public outcry, the autopsies were reviewed; wounds were found that had been ignored or ruled out, and all deaths were reclassified as homicides. A man convicted of rape became the prime suspect in 32 murders for nearly a decade. He died before he could be tried.
Over the years, the most cited source of bias in forensic pathology has been the influence of law enforcement, in part because in some places police detectives are regularly present during autopsies.
In the case of Mississippi, it may have been the other way around: the prosecutor, Mr. Jubera, said there was no suspicion of foul play in Emberly’s death until the pathologist called it homicide. That left, he said, only one suspect: his mother.
Emberly’s autopsy
For months after Emberly’s death, Jocelyn McLean called the county forensic and the state’s forensic doctor’s office looking for an explanation for why her daughter had died, worried she had lost a warning sign. or that the hospital had released the baby too soon.
He received no answers. The coroner’s office had a massive backlog that forced families, police and courts across the state to wait long periods for autopsy reports.
But unlike many jurisdictions, Mississippi medical examiners were board-certified forensic pathologists working in a state-of-the-art laboratory. However, 15 months passed before the local prosecutor was notified by the case’s pathologist, Dr. J. Brent Davis, that the death was a homicide.
Ms. McLean, who lived near Atlanta and had been visiting Mississippi when she began giving birth, saw the first sign of trouble in December 2017, when she received a Facebook message from a social worker in the Division of Georgia Family and Child Services warned that if Ms. McLean’s two living children were not seen by the agency within 48 hours, they would be …
