RCMP slated to deliver update on missing six-year-old Alberta boy

RCMP are expected to give an update later today on the search for a six-year-old boy missing from the southern Alberta Rockies. Darius Macdougall was reported missing on Sept. 21 after he didn't return from a walk with six young relatives in the Crowsnest Pass area, where his family had been camping.

Mounties say his chances of survival in the mountainous terrain are slim, but that they won't scale back the search, noting there's been nothing to suggest foul play.

The boy's family says they're grateful to the searchers and won't rest until he's brought home. Hundreds of searchers have spent the last 11 days combing through the area with drones, helicopters and police dogs, navigating everything from elevation changes to deadfall.

The boy from Lethbridge, Alta., has autism, which rescuers say complicates the search because it may prevent him from responding to his name.
