The defence lawyer in the Norman Larue murder trial in Whitehorse questioned the identity of the victim Thursday in court.
Lawyer Ray Dieno suggested the evidence used to identify the body of Gordon Seybold could not be trusted.
When Seybold’s home burned down in 2008, investigators could not be sure whose charred body they found inside.
Forensic pathologist Charles Lee testified he had very little to work with, and what he did have was so severely burned, he couldn't identify the man, nor determine cause of death.
Dr. James Severs, a forensic dentist, was called in to identify the body through dental records.
Severs has helped identify hundreds of severely damaged corpses over the years and was part of a B.C.-Yukon forensic odontology team sent to Thailand eight years ago to help identify tsunami victims.
He told the court identifying Seybold’s body using dental records was fairly straightforward.
Defence lawyer Dieno questioned Severs’ credentials and his credibility. He suggested the Seybold ID was nothing more than "a best guess."
This week jurors also heard Seybold was a reclusive marijuana grower who sold to friends on the honour system.
RCMP investigator Kirk Gale testified Seybold’s grow-op wasn't necessarily the biggest they've seen, but described it as the cleanest and most sophisticated he's come across in the territory.
The trial resumes Monday.
