A man is dead after being hit by a vehicle Saturday night.
According to Sgt. Pete Dugan with the Tucson Police Department, the collision happened at South 6th Ave. and West Ohio St.
Detectives say the man was not in a crosswalk while walking eastbound across 6th Ave., just north of Ohio St.
The driver of the vehicle that hit the man pulled over, but before he could help, the man was hit by a second vehicle that fled the scene. The second vehicle is described as an unknown white Sedan.
Speed or impairments do not appear to have been a factor in the initial collision.
