Toronto Police release cause of death of Barry and Honey Sherman.

Toronto Police announced that  Homicide investigators are taking the lead in the case of billionaire couple Barry and Honey Sherman.

Police say they both died from ligature neck compression.

Sherman was the founder of pharmaceutical giant Apotex.

The Sherman family had released a statement before the cause revealed for a thorough and objective investigation by police and requested that media not report further on any cause of death until the investigation is complete.

Emergency crews were called to the mansion in the Bayview Avenue and Highway 401 area around 11:45 a.m. ET on Dec 15  for reports of a medical emergency, where Toronto police say a male and a female were pronounced dead.

On Saturday, police remained tight-lipped about the investigation. They have yet to confirm that the Shermans were the deceased, despite the family’s statement, and Apotex confirming that its founder Barry Sherman and his wife had died.

On Saturday, Const. David Hopkinson told CBC News police will combine the autopsy results with the findings of their investigation before coming to a conclusion about what happened.

The cause of the deaths are finally released today.

The Shermans were among Canada’s most generous philanthropists and also organized funding for charitable causes through the Apotex Foundation. The couple made numerous multimillion-dollar donations to hospitals, schools and charities and had buildings named in their honour.
