At 6:47 a.m. Sunday, emergency responders were dispatched to I-84 near the Northeast 43rd Avenue exit and the overpass of Cesar E. Chavez Boulevard.

When police arrived, they found the driver of a tow truck laying on the pavement, injured, in front of his truck. Officers say they learned that the driver had just finished loading a vehicle when he was struck by a passing vehicle, believed to be another tow truck.

The suspect vehicle continued driving and has not been located.

The injured driver, a 27-year-old man, was taken to a local hospital with serious injuries, including a broken arm and a broken leg.

The suspect vehicle is described as a Ford tow truck with a wheel lift mechanism on the back. Police say there are conflicting accounts of what color it is.

If anyone saw the crash, has video of the suspect’s truck or has information about the driver involved, you are asked to email Portland Police at crimetips@police.portlandoregon.gov
