Police searching for driver two days after truck lands in B.C. river

HOUSTON, B.C. - Police and search and rescue volunteers are continuing to look for a man two days after his truck was found in a British Columbia river.

RCMP Cpl. Dave Tyreman says that early Tuesday morning, a passerby spotted the vehicle in the water near the northern Interior community of Houston.

He says police learned the vehicle left the forest service road, rolled down a steep embankment and ended up in the river.

The female passenger was rescued by first responders but the male driver is still missing.

Tyreman says alcohol is believed to be a factor in the accident.

No names have been released.
