Police said a 50-year-old woman, identified by her neighbors as Loretta Traynor, the mother of three, was recovering in hospital after being seriously injured in the attack.
A close family friend told CTV News Toronto on Saturday that the couple’s only surviving son, Sam, was absent from college at the time of the shooting.
Police were called to the quiet area at around 1:20 a.m. Friday after many residents called police to report gunshots and screaming coming from a house.
Several officers rushed into the area, including members of the tactical unit, and when they arrived at the scene, police said gunshots could still be heard coming from the house.
Police later discovered the bodies of four members of the Traynor family.
The suspected gunman, later identified by police as Mitchell Lapa, 48, of Winnipeg, was also found dead inside the home on Friday morning after sustaining a self-inflicted gunshot wound, investigators said .
Police said Lapa was an “uninvited person” at the house and his white Ford pickup was seen parked outside the residence early Friday morning. Lapa is believed to be Loretta’s brother.
The homicide unit, police said, is still investigating the motive for the shooting.
“Investigators also want to speak to anyone who knew the sole attacker, Mitchell Lapa, as they seek to understand the motivation and reasons for this attack,” police said in a press release.
Friends, neighbors and colleagues paid tribute to the family members who were killed. A memorial grows in front of the house.
