October 15, 2007 R. v. William Mullins-Johnson—first degree murder—Mr. Mullins-Johnson was exonerated by the Ontario Court of Appeal after twelve years of imprisonment having been wrongfully convicted of murdering his young niece, a conviction based in large part on the evidence of now discredited pathologist Dr. Charles Smith (with co-counsel James Lockyer).

Bill Mullins-Johnson Walks Free after 12 Years in Federal Prison “But in 2001, finally there was someone other than his mother, who was willing to listen to him and eventually come to believe Mullins-Johnson was innocent. “There was not a shred of forensic evidence linking Bill to the crime scene,” says David Bayliss, a lawyer with the Association in Defence of the Wrongfully Convicted. “This was an alleged sex-homicide. There was no semen. There was no blood. There was no saliva, no hair, no biological material whatsoever connected Billy to Valin or the bed where she was found dead.”

In September 2005, armed with the new medical findings, Bayliss headed back to court. The federal justice minister immediately ordered a full review of the case. After 12 years in federal prison, Bill Mullins-Johnson was released on bail pending the review. “When I finally stepped out the doors there I was looking up at the sky. I forgot how blue the sky can be,” says Mullins-Johnson.”
