A TriMet bus driving in Gresham fatally struck a pedestrian who walked out in front of it early Tuesday, police said.

The bus was out of service and heading south along Southeast 182nd Avenue when a man stepped off the sidewalk near Division Street and into its path, said Ben Costigan, a Gresham police spokesman.

The man, who has not been identified, died at the scene, police said.

Costigan said police are also investigating a second crash that occurred along Southeast 182nd Avenue on Monday night.

A speeding black Mercedes Benz SLS 550 flipped when it hit a curb near Yamhill Street around 9:25 p.m., smashing into a pole and fire hydrant and sending the engine of the luxury car out into the street, police said.

Police found a man in the passenger seat with life-threatening injuries and rushed him to a hospital, Costigan said. The driver fled the scene.

Anyone with information on the Mercedes crash is asked to call the Gresham Police Tip Line at 503-618-2719.
