Barry Sherman, a billionaire businessman and philanthropist, was found dead alongside his wife Honey in their Toronto mansion Friday morning, police sources told the Sun. Officially, Toronto Police aren’t commenting on the tragedy — other than to call the deaths of one of Canada’s richest couples “suspicious.” However, sources say police were working Friday night on the theory the demise of the billionaire Apotex founder and his wife, which has stunned the city and those who knew them, may have been a murder-suicide.
