Toronto police release cause of death of billionaires

TORONTO – Toronto homicide detectives have taken over the investigation of the deaths of billionaire Barry Sherman and his wife after autopsies showed they died from "ligature neck compression."

Police released a statement Sunday reporting the cause of death. Authorities also identified pharmaceutical magnate Sherman and his wife, Honey, as the two people found dead in a north Toronto mansion Friday.

Police call the deaths suspicious, but on Friday also said that there were no signs of forced entry and that they were not looking for any suspect.

The Sherman family issued a statement Saturday urging police to conduct a "thorough, intensive and objective criminal investigation" into the deaths and calling on the media to avoid speculating on the cause of the deaths.
