3 members of a B.C. family are dead, one is in critical condition and a 16 year old boy wasn't seriously hurt.

Dead is the 47 year old driver of the car, his two daughters, aged 19 and 13 and the 42 year old wife is in critical condition.

Two men in another vehicle were also hurt, one of them seriously when two vehicles collided near Rosetown yesterday (Sun) afternoon.

Investigators say the crash happened in a rainstorm when spray from a large truck may have obscured the road, just as the car carrying the B.C. family pulled out to pass.
