MOSES LAKE, Wash. (AP) — Authorities say a Washington woman suffered severe burns after gasoline fumes ignited when gas was being pumped into a garbage can in a car's backseat.

KOMO-TV reports the Grant County Sheriff's Office says the woman, who was a passenger early Saturday morning at a Cascade Valley Grocery convenience store, was smoking a cigarette, which ignited the flames.

Deputies later found a large amount of marijuana in the car's trunk.

A bystander took the woman to Samaritan Healthcare in Moses Lake.

The male driver who was pumping the gas ran away.
