Deschutes County 911 received a call from an Uber driver late Friday evening reporting she had just been attacked in her vehicle by a passenger she was transporting. Several Deschutes County Sheriff’s Office deputies responded to the area of Gateway Loop and Skyline Ranch Road, where the victim was waiting on scene, according to a press release.

Deputies learned the driver was transporting an intoxicated male, later identified as Mark Mastalir, 52, of Bend, to a residence on Skyline Ranch Road in Bend. The driver was not provided his specific address on Skyline Ranch Road, only a general area in which to transport Mastalir. She was told he could lead her to the correct address when they were close.

While en route, Mastalir allegedly attacked the driver by pulling her hair and grabbing her right arm, causing her vehicle to swerve dangerously into oncoming traffic and onto the shoulder of the road. Mastalir allegedly continued attacking the female driver after the vehicle had stopped, the report said.

As the alleged assault transitioned to outside the vehicle Mastalir began to slam the driver’s head on  the asphalt roadway.

The driver fought Mastalir off inside and outside of her vehicle with pepper spray, a handheld stun gun and a collapsible baton. She was treated on scene by medics from Bend Fire & Rescue and was later transported to St. Charles Bend by private vehicle. 

Deputies located Mastalir near the scene, and took him into custody. Mastalir suffered severe lacerations to his head, and was treated by medics on scene before being transported to St. Charles Bend. After his release from the hospital, deputies booked Mastalir into the Deschutes County jail on suspicion of second-degree kidnapping, second-degree assault,  unlawful use of a weapon, coercion, menacing, reckless endangering, first-degree criminal mischief and resisting arrest.
