On a typical case, he might have to decide whether a child had been shaken to death or accidentally fallen from a highchair.
Dr. Charles Smith was once considered top-notch in his field of forensic child pathology. In 1999, a Fifth Estate documentary singled him out as one of four Canadians with this rare expertise.

For 24 years, Smith worked at Toronto's Hospital for Sick Children. In the hospital's pediatric forensic pathology unit, he conducted more than 1,000 child autopsies.
But Smith no longer practises pathology. An Ontario coroner's inquiry reviewed 45 child autopsies in which Smith had concluded the cause of death was either homicide or criminally suspicious.
The coroner's review found that Smith made questionable conclusions of foul play in 20 of the cases — 13 of which had resulted in criminal convictions. After the review's findings were made public in April 2007, Ontario's government ordered a public inquiry into the doctor's practices.
Some have accused Smith of taking on a role larger than pathologist. The lawyer for Brenda Waudby said he was on a crusade and acted more like a prosecutor. Waudby was convicted in the murder of her daughter after Smith analyzed the case.
A pubic-like hair found on her daughter went missing during Smith's investigation. It was discovered he had kept the hair in his office before police found it five years later. In the end, Waudby's charges were dropped and the child's babysitter was convicted.
Smith said he had a passion for uncovering the truth in child deaths. The Ontario pathologist told media lampooning him he had "a thing against people who hurt children." He welled up when speaking about a mother looking for the cause of her baby's death.
Smith had been in search of his own personal truths. He was born in a Toronto Salvation Army hospital where he was put up for adoption three months later. After years of looking for his biological mother, he called her on her 65th birthday. But she refused to take his call.
Smith's adoptive family moved often. His father's job in the Canadian Forces took them throughout Canada and to Germany. He attended high school in Ottawa, and graduated from medical school at the University of Saskatchewan in 1975.
Sick Kids tenure
Hired by Toronto's Hospital for Sick Children in 1979, Smith worked in surgery for a year and then moved on to pathology training. A pathologist studies diseases and illnesses by assessing matter such as cells, tissues, organs and fluids. Pathologists also examine biopsy material, and give a subsequent diagnosis.
When it comes to autopsy reports, the field of pathology can be a subjective one. It's based on research and opinion, and it's especially controversial in Canada, where there is no formal training or certification process. Only a handful of practitioners in Ontario are entrusted with the job — and they've learned by doing.
With child victims, forensic analysis is rarely cut and dried. It can take an infant up to 24 hours to die of a shaking incident, which is a crime that doesn't leave evidence the way a regular killing might.
After his initial training at Sick Kids, as the Toronto hospital is known, Smith began conducting child autopsies in 1981. He started with children who had died of accidental and natural causes. By the late '90s, Smith saw more forensic child cases than any other pathologist across the country.
Smith's unit used arrest warrants to reinvestigate cases of sudden infant death syndrome (SIDS). He oversaw the autopsies of exhumed babies that led to new murder charges.
In one such case, Smith appeared before a court in the death of six-month-old Sara Podniewicz. He concluded she had been dead for up to 15 hours before her parents reported the death. The parents had told a 911 operator the girl had died just moments before. Smith's analysis led to second-degree murder charges.
In 1991, a family in Timmins, Ont., was the first to raise questions about Smith's work. He had concluded their one-year-old baby had died from being shaken. The child had been under the care of a babysitter who said the baby had fallen down stairs.
In court, experts challenged Smith's opinion, which had resulted in the babysitter's charge of manslaughter. The judge in the case stated Smith should have taken other causes into consideration.
Once the most prolific pathologist, Smith began getting a reputation for late cases, and his disorderly desk produced samples that had gone missing.
In 2002, he received a caution from the Ontario College of Physicians and Surgeons. The college said he was being "overly dogmatic" and had a "tendency towards overstatement."
In June 2005, Dr. Barry McLellan, Ontario's chief coroner, started the review of 45 child autopsies conducted by Smith between 1991 and 2002. The review, released in April 2007, found that Smith had made mistakes in 20 cases involving the deaths of children. The review cast doubt on criminal convictions in 13 of the cases.
"I am very surprised with the overall results of the review, and concerned," McLellan said. "In a number of cases, the reviewers felt that Dr. Smith had provided an opinion regarding the cause of death that was not reasonably supported by the materials available for review."
The chief coroner said the results of the review were being shared with defence and Crown attorneys involved in all of the relevant criminal cases.
After resigning from Sick Kids in 2005, Smith accepted a pathology position in Saskatoon. He was fired after three months. A tribunal later reinstated him, but without a licence, Smith was unable to practise.
Smith told media his marriage ended in light of stress from the highly publicized events. He had lived with his wife and two children on a farm north of Newmarket, Ont.
As a member of the Christian and Missionary Alliance, Smith says he has been fuelled by his life's purpose — finding out the truth for parents who have lost babies.
