Portland Police spokesman Sgt. Pete Simpson said Brock hit the back of the city truck, which hit a Subaru, which hit another Subaru, which likely hit a fifth car that left the scene perhaps not knowing it had been tapped.

Brock told police he had fallen asleep at the wheel. He was evaluated for signs of intoxication, which responding officers couldn't confirm.

There were no signs of Brock being otherwise impaired, so police cited him for careless driving.

Simpson said there were no serious injuries and that the investigation is closed.
