Portland authorities are hunting for the driver of a white pickup truck that fatally struck a woman who had been riding in the vehicle just seconds before.

Police, in connection with Crime Stoppers of Oregon, said Tuesday they would offer a $2,500 reward for information that leads to a suspect in the Nov. 11 hit-and-run that killed Stephanie Diane Marcortt in the Pearl District.

Marcortt, 54, was riding in the pickup along Northwest Ninth Avenue near Glisan Street around 2:20 a.m. when, for unknown reasons, she exited through the passenger door and was run over by the truck, police said.

The truck, a white crew cab pickup, was last seen driving north along Ninth Avenue, according to investigators.

Anyone with information is asked to call 503-823-4357 or submit a tip online.
