Dental records have confirmed that a youth's body discovered northeast of Barrie, Ont. is that of Brandon Crisp, the teen who ran away from his home on Thanksgiving Day.

However, the post-mortem examination, which began Friday morning and went for seven hours, might not be fully completed until Saturday.

Steve and Angelika Crisp, Brandon's parents, will be the first to learn of the findings, CTV Toronto's Jim Junkin reports.

They have asked for privacy.

Brandon left home after he got into an argument with his parents about his constant Xbox video game playing on Oct. 13. His family never heard from him again.

Police launched boat, helicopter and foot searches in the areas where they thought Brandon may have headed, including to the rail trail where he was last seen alive. Volunteers supplemented the police search by expanding the area.

Police also restarted the search last weekend, canvassing drivers and others in the area where Brandon was last seen to see if anyone knew something that might help find the youth.

On Wednesday, locals out deer hunting stumbled upon a body matching Brandon's description in a wooded area east of Barrie, more than three weeks after he first disappeared.

They say they don't think it had been there for three weeks.

The hope is that forensic experts will be able to determine exactly when and how Brandon died.
