One man is dead and another injured after their vehicle collided with a tree early this morning.

The Snohomish County Sheriff’s Office responded to reports of an accident in the 18500 block of 51st Avenue Southeast around 4 a.m., prompting them to close the road until around 8:30 a.m.

A sheriff’s spokeswoman said they are unsure if the tree was in the road, or if the vehicle left the road, struck the tree and returned to the roadway.

The driver died at the scene and the passenger was transported to a hospital. The identities, ages and hometowns of both victims have not been disclosed.
