The CBC's Linda Ward reports from outside a home in Oshawa, Ont., where five people are dead after gunshots were fired overnight.

"They were a family that cared for each other quite a bit," she said. "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," hesaid. "It'll be towed away, and we'll probably get a search warrant to look inside."

Herouxsaid she had never seen the truck before.
