On Sunday afternoon, the man said he spoke with another person who was also concerned about the family’s welfare because they hadn’t been answering their phones or their door. The neighbour said the person smashed a window with a propane tank and went inside, where they found the bodies. The person also removed the family’s St. Bernard dog from the house to care for.

Officers were dispatched to the home at approximately 6:30 p.m. on Sunday in relation to what police referred to as an “unknown trouble.”

They entered the home, “as there were immediate concerns for the person’s well-being,” police said in a media release. Upon entering the home, officers located three deceased people.

Detectives from Greater Sudbury Police’s Criminal Investigation Division are working in collaboration with the Coroner’s Office on the investigation.

The Ontario Forensic Pathology Service will conduct the post-mortem exams on behalf of the Office of the Chief Coroners Office to determine final cause of death and assist in this investigation.
