A Pullman man jumped out of a moving car and suffered a serious head injury on Wednesday around 6 p.m. on North Grand Avenue, said Pullman Police Cmdr. Jake Opgenorth.

The car was traveling northbound at 35 mph when the man, 24, jumped from the vehicle, he said.

The 26-year-old female driver and the passenger were allegedly arguing when the passenger jumped, Opgenorth said.

The driver did not stop after the man jumped out, witnesses say. She eventually returned to the scene. There were two children in the back seat, according to Pullman Radio News.

The passenger, who was left unconscious, was taken to a Spokane hospital, according to Pullman Radio News.

“There’s nothing criminal that occurred,” Opgenorth said. “For the person who jumped out of the car and the people who were in the car, nothing criminal happened.”

Pullman Police are still investigating and anyone with information can contact the tip line at (509)-334-2249.
