Investigators comb through sewers for clues to deaths of Barry and Honey Sherman
A source with knowledge of the investigation says that the move was done 'out of an abundance of caution'
Forensic investigators are now combing through sewers looking for clues into the deaths of a billionaire Canadian couple "out of an abundance of caution," a source close to the investigation has told CBC Toronto.
Apotex founder, Barry Sherman, 75, and his wife Honey, 70, were found dead in their North York home on Dec 15.
Investigators could be seen working with city employees Saturday to open up sewer grates near the house.
The team plans to comb through more sewers near the Sherman's mansion on 50 Old Colony Road, near Bayview and the 401 as soon as they can coordinate the operation with the city.
The forensics team were assisting homicide detectives who have officially taken the lead in the case although it remains a "suspicious death investigation," rather than a homicide. Post-mortem examinations have revealed that both Shermans died from "ligature neck compressions," meaning strangulation.
Police have remained tight-lipped about details of the investigations but a detective with the Toronto homicide squad, Brandon Price, previously said investigators found no signs of forced entry into the couple's house, and police were not "currently seeking or looking for an outstanding suspect."
Mourned by thousands
CBC News has learned that the Shermans were found by the pool in their basement and that investigators have found no security cameras inside or outside the home.
The Sherman's funeral, held Thursday, was attended by thousands including Prime Minister Justin Trudeau, Ontario Premier Kathleen Wynne, Ontario Health Minister Eric Hoskins and Toronto Mayor John Tory.
