A local pathologist performed an autopsy on Valin. Then "consultation reports" were sought from Smith and four other specialists, based on tissue samples and other evidence from the autopsy. Smith was the only consultant to conclude Valin was sexually assaulted at the time of death. That contradicted the defence's point that Valin, who had a history of vomiting in bed, might have died of natural causes. The jury convicted, which the Ontario Court of Appeal upheld in 1996. The Supreme Court of Canada dismissed a further appeal in 1998.
