It's a case that has yet to be solved.
On December 15, 2017, the bodies of Apotex chairman and CEO Barry Sherman and his wife, Honey, were found on the deck of their indoor swimming pool at their North York home.
The couple was found strangled by belts that had been looped around their necks.
Originally ruled a murder-suicide, Toronto Police later said it was a double murder. However, very few details about the investigation have been released.
What we do know is that the Sherman family undertook a separate, private investigation and that a $10 million reward was put on the table for information leading to the suspect or suspects in the case.
Now, on the one-year anniversary of their violent deaths, the public still hasn't learned much about what police have uncovered over the past 12 months.
However, that doesn't mean that things haven't been done.
"We know there's been a lot of search warrants and different processes occur," said public safety analyst and NEWSTALK1010 contributor Chris Lewis. "I'm still confident someday we'll know what happened."
In fact, Lewis says it's a blessing in disguise that details have not been leaked to the public.
"That does nothing to help an investigation and it also becomes things that investigators have to fight later at a trial - just stupid rumours that are in the community or on social media."
He says plenty of additional evidence was gathered by those who undertook the private investigation.
However, he lauded the Toronto Police as one of the best police forces around, and if their detectives can't solve it, then it may never be solved.
"I think when we find out, we'll say 'wow'," he added. "This will be one there will be books and movies about [...] because it's just so complicated and so high profile."
