A local forensic pathologist whose autopsy files are under review is linked to a double murder investigation in Nebraska.

CTV News has learned Dr. Michael Belenky is connected to an unsolved double homicide in Omaha nearly three years ago, and that cold case investigators from Omaha had come to Calgary.

Belenky is not a suspect, but investigators say they are following all leads in the case.

Belenky was a pathologist at the Creighton University Medical School in Omaha before coming to Calgary to be an assistant medical examiner.

His supervisor was Dr. William Hunter.

In March of 2008, Hunter discovered the bodies of his 11-year-old son Thomas Hunter and housekeeper Shirlee Sherman in the family home.

Both had been stabbed to death.

The news comes a day after Alberta Justice announced all of Belenky's autopsy files are under review.

They say inconsistencies in one autopsy report sparked an investigation.

The news sent shockwaves through the criminal justice community.

Veteran defence attorney Allan Fay has a number of murder cases coming up where Belenky was the medical examiner.

"The thought that some people are spending time in jail on serious matters… medical examiners shouldn't be involved unless there was a death. People convicted of manslaughter, second-degree murder, that sort of thing, based on the possibility of flawed reports," he said.

Belenky left the medical examiner's office in Calgary in January.

He was let go from his role as an assistant professor of pathology at the University of Calgary Tuesday, a role he had held since 2008.

Criminal justice experts say investigators have to be careful in how they proceed with this case.

"The first thing to do is make sure we don't rush to a judgment that this is a recurring pattern or maliciousness is involved," said Doug King with Mount Royal University.

"If it's a one-time only honest mistake, mistakes happen and will have no ramifications on the criminal justice system. If it's a pattern because of incompetence, making errors, maliciousness, this brings criminal justice into disrepute."
