Investigators believe a driver who hit a woman in a Gresham crosswalk was smoking marijuana just seconds before the collision, according to the Gresham Police Department.
Emergency crews responded to Northeast 181st Avenue and Burnside Street at 8:09 a.m. Monday.
Investigators said a 2008 Toyota Prius was heading eastbound on Burnside when it struck a woman in a marked crosswalk.
Police said the 46-year-old woman was unconscious when paramedics arrived, but she is expected to survive. However, she sustained significant injuries including a broken arm, compound fractures to her leg, a broken pelvis, a spinal fracture and head injuries.
The woman is a three-time kidney transplant recipient, according to officers.
The driver, identified as 27-year-old Jacob Walters of Portland, remained at the scene and cooperated with the investigation.
Witness statements and the initial investigation indicated Walters was smoking marijuana seconds before the crash, according to police.
The degree to which potential marijuana consumption was a factor is still under investigation.
Detectives determined speed was not a contributing factor to the crash.
Walters was arrested and booked at the Multnomah County Jail on charges of fourth-degree assault, reckless driving and reckless endangerment.
He was later released from jail and will appear in court Tuesday afternoon .
