Alleged shooter among 5 people found dead in Oshawa, Ont., home, police say

Five people were found dead in a home east of Toronto after an early morning shooting, police say, including the person believed to have carried out the killings.

Const. George Tudos, spokesperson for the Durham Regional Police Service, said multiple callers reported hearing gunshots inside the Oshawa, Ont., residence, located near the corner of Harmony Road and Parklane Avenue, around 1:20 a.m. ET.

Police said four males and one female were among the dead, and at least two of them were minors. Tudos said that police are awaiting confirmation on their ages from the coroner.

"Investigators believe the suspect died from a self-inflicted gunshot wound, and no other suspects are outstanding," said Durham police in a statement. 

Police also said the shooter and victims were "known to each other."

Investigators have not yet provided information about the alleged shooter's identity, age or gender.

Wounded woman taken to hospital

Officers also found a 50-year-old woman suffering from a gunshot wound to her leg, and she was taken to a local hospital for treatment. Her injuries are considered serious but non-life threatening, he said.

Durham police announced the discovery of an "unknown device" at the home shortly after 3 p.m. Friday and said they would secure the area to investigate.

Police are not looking for any more suspects, and there is no ongoing threat to community safety, Tudos said.

Family friends and neighbours said the residents of the home are Chris and Loretta Traynor, along with their four children, Sam, Brad, Adelaide and Joseph.

Neighbours describe hearing multiple gunshots

Michele Heroux, a nearby neighbour who has lived in the area for nearly 30 years, said she heard up to 10 gunshots and screaming coming from the home. 

Carol Gibson, who lives down the street from the crime scene, said she was startled awake by the shooting.

"The first shot woke me up, and then I heard about four or five more after that," Gibson said in an interview. "Then a woman screamed, and there were two shots after that."

Gibson said she had known the family in the house for around 20 years.

"They were a family that cared for each other quite a bit," said Gibson. "If they weren't playing baseball, hockey or shooting hoops on the driveway, they were out raking leaves, and they did it as a family. A very caring family."

A white pickup truck with Manitoba licence plates is still parked outside the residence, and Tudos said it is part of the investigation. 

"I know that vehicle is part of the crime scene, and it's being looked at by our forensics officers right now," Tudos said. "It'll be towed away, and we'll probably get a search warrant to look inside."

Heroux said she had never seen the truck before.
