''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''
''They used a hydro-excavator as "a large vacuum" and a magnet to locate any "suspicious metals," a source said. They then took the gathered contents to a work yard and combed through the material, looking for anything that could be considered as evidence.
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.''
