Embry McLean-Bernard, born six weeks premature in Mississippi, weighed less than five kilograms when doctors sent her home. She did not cry or eat, her mother said, and it was not two days before she began to gasp. Jocelyn McLean took her daughter to the nearest emergency room, but the baby is already turning blue.
The medical team went straight to code the blue, pumping air into the baby’s lungs, trying to draw an intravenous line into Emberley’s neck and scalp, pushing her with a rectal thermometer – but her vital signs continued to fail. After four hours, they gave up.
A state forensic doctor concluded that the death was not due to a medical problem, but was a homicide resulting from a “blunt force injury with signs of suffocation.”
Ms. McLean, a 29-year-old black mother with two other young children, was charged with murder.
Mrs. McLean was stunned. The emergency room doctor who tried to save the baby was shocked. But Dr. Joy Carter, a forensic pathologist wiretapped by the defense to review the case, saw a very familiar pattern: a forensic pathologist who made a decision without talking to the doctor or even reviewing hospital records. Supervisors who signed his decision. A criminal justice system that all too often sends black people to prison based on evidence that someone else may not have convicted. In court, Ms. McLean and her lawyer recalled, Ms. McLean was called a “monster.”
She spent more than a year in prison before reviewing Dr. Carter’s autopsy forced the state forensic court and prosecutor to admit that the baby’s injuries could be explained by desperate attempts to save her that night.
“I am grateful that this woman did not kill her child,” said Stephen Jubera, assistant district attorney in Talahachi County, after the charges were dropped. “But the other side of it is, ‘My God, I imprisoned a woman.'”
The National Death Investigation System, a collection of forensic doctors, freelance experts and selected forensic doctors who may not have a medical degree, is responsible for investigating suspicious and unexplained deaths. Wrapped in a mantle of scientific authority, its practitioners translate the complexity of disease, decomposition, toxicology, and physics into simple categories such as accident, homicide, or death by natural causes, driving the worst cases of the legal system and having a huge impact on jurors.
And yet these experts are far from infallible. Because forensic science of all kinds is facing a test of its reliability, with blood splatter patterns, hair matches, and even fingerprints no longer considered irrefutable evidence as it once was, the science of death has been shaken in recent years by questions about whether the work of forensic doctors is affected by racial bias, prejudices and the powerful influence of law enforcement agencies.
A study published last year by the Journal of Forensic Sciences found evidence of cognitive bias when 133 forensic scientists were presented with identical medical evidence in hypothetical cases involving the death of children. Deaths are more likely to be declared an accident if the child is white and the caregiver is a grandmother; they were more often defined as murder when the child was black and cared for by the mother’s friend.
The study, authored by Dr. Carter, touched on the very essence of the heated debate over forensic pathology. He showed, his authors said, that judgments that must be based on science can be clouded by prejudice when medical experts allow their findings to be influenced by non-medical information. But many leaders in the field insist that forensic doctors must look at the whole case before them – including statistics showing that boyfriends are more likely than blood relatives to abuse children.
The new study was met with an explosive reaction. The National Association of Medical Experts complained that the study was poorly designed and conducted incorrectly. One member of the association filed an ethical complaint against Dr. Carter and three other forensic pathologists cited as authors, arguing that the document would cause “incalculable harm to our profession.”
One of the authors suggested withdrawing the article, just to end the dispute. “I can’t even sleep at night because of all the hatred and rage I’ve received,” he wrote in an email to The Times. Disappointed, 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 say the continued police burden on Mr Floyd is not the cause of his death – have catapulted the debate over bias in the public arena.
Dr Andrew Baker, a chief medical examiner in Minneapolis who will continue to perform the official autopsy on the Floyd case, admitted in an address to the American Academy of Forensic Sciences in 2015 that “blatant failures of the system have led to tragic consequences for the innocent. defendants’.
But he attributes the failures of bad apples to the profession, not the inability to take precautions against mistakes. “Open failures – such as incompetence, dishonesty, fraud and corruption – are not cognitive biases,” he said.
Dan Simon, a law and psychology professor who has worked for six years on the federal committee tasked with creating better forensic standards, said forensic doctors have been uniquely resilient to reform. “They stand out for their disobedience,” he said. “And that’s a serious problem.”
Wrong autopsies and wrongful sentences
Critics say the reluctance to allow for the possibility of bias, combined with a lack of diversity in the profession and traditionally cozy relationships with law enforcement, can increase the chances of racial differences when medical experts make mistakes. A number of blacks and Latinos have been released in recent years, some of whom have been sentenced to death after autopsy findings that helped convict them have been refuted.
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 so brutally that it killed her. Mr Benavides was released in 2018 after experts said the cause of death presented in the trial was anatomically impossible.
Before intervening in the case of Emberley’s death in Mississippi, Dr. Carter spent much of her career working on racial bias in the forensic profession.
She attended medical school at Howard University, then the only historic black school with a residency in pathology, and in 1992 became the first black woman to head the forensic office in Washington. She realized that there was virtually no pipeline for training and recruiting whites in her profession, although more than half of the country’s homicide victims were black.
She later heard absurd allegations from fellow forensic doctors, including that black people were impenetrable to pain and that no bruises could be found on dark skin. She began to believe that the lack of intercultural learning caused mistakes with great consequences.
Some of these ramifications became apparent during her residency in forensics in the 1980s, when she was the only black pathologist in a Miami forensic pathologist’s office.
A series of poor black women appeared dead in gloomy conditions – cheap hotels, abandoned buildings, open fields. Although the women were found in similar positions, the deputy forensic doctor believes that their death was caused by a combination of cocaine use and voluntary sex. Almost all were classified as drug-related accidents.
Dr. Carter pushed away. The victim she examined had a serious habit of cracking, but Dr. Carter refused to call the death an accident.
She was right – after a public protest, the autopsy was examined; injuries were found that were ignored or dismissed, and all deaths were reclassified as homicides. A man with previous convictions of rape has become the prime suspect in 32 murders in nearly a decade. He died before being tried.
Over the years, the most frequently cited source of bias in forensic pathology has been the influence of law enforcement, in part because police detectives are routinely present at autopsies in some places.
In the case of Mississippi, it may have been the other way around: the prosecutor, Mr. Jubera, said there was no doubt about dishonesty in Emberley’s death until the pathologist called it murder. That remains, he said, only one suspect: her mother.
Emberley’s autopsy
For months after Emberley’s death, Jocelyn McLean called the district investigator and the state medical tribunal for an explanation as to why her daughter had died, worried she had missed a warning sign or that the hospital had released the baby too soon.
She had no answers. The forensic office was far behind, forcing families, police and courts across the state to wait long periods for autopsy reports.
But unlike many jurisdictions, Mississippi medical experts have been certified by a board of forensic pathologists working in a state-of-the-art laboratory. However, 15 months passed before the local prosecutor was notified by the pathologist in the case, Dr. J. Brent Davis that death is murder.
Ms. McLean, who lived near Atlanta and was visiting Mississippi when the birth began, saw the first signs of trouble in December 2017 when she received a Facebook message from a Georgia Family and Child Services staffer warning that if Ms. McLean’s two living children are not seen by the agency within 48 hours, they will be …
