Arrest made in I-5 rock throwing case

SUTHERLIN, Ore. -- A Sutherlin teen is behind bars after state troopers said he was involved in the November rock throwing incident that injured two University of Oregon students.

Oregon State Police troopers said on November 26, 2012, at about 10:40 p.m., Molly Grabill, 20, of Poway, Calif., and her passenger, Chris Brewer, 19, of Vista, Calif., were driving northbound on I-5 when a rock hit their car. Troopers said the rock was larger than a baseball.

Authorities said it was thrown from the overpass at Isadore Road.

Grabill, who was driving, was hit in the face and sustained serious injures.

Brewer grabbed the steering wheel but was unable to keep the car under control as it traveled onto the shoulder and rolled on the freeway. It came to a rest facing the opposite direction.

Detectives from OSP say the investigation and tips from the public led them to Sutherlin teen Matthew Logan McKinney, 19. Authorities say they arrested McKinney at his home following a meeting with detectives.

McKinney was taken to the Douglas County Jail and was charged with second and fourth degree assault, as well as throwing an object off an overpass, among others.

State police said other arrests are pending.

Grabill is a student athlete at the UO. After the incident, university athletic director Rob Mullens urged people with information about the case to contact police.
