The shooter in Monday night's violent attack in Sault Ste. Marie, Ont., had been involved in several prior intimate partner violence investigations, police say.

The 44-year-old male gunman shot and killed four people, including three children, in a murder-suicide at two different homes in the northern Ontario community, Sault Ste. Marie Police Service said Tuesday.

A 41-year-old was found deceased at a home on Tancred Street first after a 911 call about someone breaking into the home.

Minutes later officers found a 45-year-old with gunshot wounds at a home on Second Line East and sent them to hospital.

Inside the second home was where the bodies of the children – ages 6, 7 and 12 – were found along with the gunman, who died of a self-inflicted gunshot wound.

Detectives continue to investigate both scenes.

"After obtaining a search warrant for the residences, officers located and seized two firearms inside the home on Second Line East: one long gun and one handgun," Sault police said in a news release Wednesday.

"Forensic analysis, ballistics analysis and the post-mortem report will be required to determine how the firearms were used."

The Ontario coroner's office is assisting with the investigation, providing forensic analysis.
