A new report from The Toronto Star says private investigators looking into the deaths of billionaire philanthropist couple Barry and Honey Sherman believe they were murdered.
The Star says evidence obtained by the team hired by the Sherman family say the pair were the victims of a double murder, not a murder-suicide.
75-year-old Barry Sherman and his wife, 70-year-old Honey Sherman were found dead in their North York mansion December 15.
Police say an autopsy found the cause of death to be "ligature neck compression" and the investigation is ongoing.
The Star chief investigative reporter Kevin Donovan, who wrote the story, spoke with CP24 about the new information they learned.
"Some of the new information that's being revealed relates to marks found on their wrists indicating that their hands were bound," he said.
Newstalk 1010's crime specialist Mark Mendelson, who was a detective with Toronto Police for 14 years, says that is something he believes police would have known about from the first autopsy.
"I've been to hundreds of forensic autopsies and there's no way in the world you're going to miss markings indicative of bindings on the wrist at an autopsy. It's there, you can't miss it, so police have had that information since homicide has taken over."
"At the end of the day it's when someone from homicide is going to get up in front of a lectern at police headquarters and they will make the official determination of what this is." Mendelson said.
Donovan told CP24 "it's really going to be up to the police, more than the private investigation team to solve this case."
Toronto police have been at the family’s home since the couple was found dead continuing to investigate.
Toronto police spokesperson Mark Pugash told the Star on Friday that the deaths remain classified as "suspicious." He said when "we are in a position to release more information we will do so."
