An incoming USC freshman was killed during a hit-and-run incident on Interstate 110 Saturday, according to a California Highway Patrol report.

CHP responded to a call of the traffic collision on the southbound side of the freeway, north of 37th Street at 2:43 a.m, where Matthew Olson was walking between FasTrak lanes and initially struck by a passing Toyota, and then was hit again by another vehicle in the first lane.

The first driver “stopped to render assistance” but the second driver, who is yet to be identified, “did not stop and continued on,” according to the report. The victim was pronounced dead at the scene by Los Angeles Fire Department Paramedics at 2:58 a.m.

CHP Officer Ramberto Salcido said the reason why the student was on the freeway is still unknown as of Monday.

Olson, a recent graduate from Corona del Mar High School, intended to major in business administration at USC. Throughout his high school years, he was a member of the 2018 National Championship volleyball team. Andy Read, one of the volleyball coaches who worked with Olson for a year, said that he was going to miss him in an email to Annenberg Media.

“Matt was all about the team,” Read wrote. “He never put himself first, he put his teammates and the success of the team ahead of his own personal goals or agenda … That is what I will miss most, the pure joy and enthusiasm he brought on and off the court. Those memories and images are etched on my heart and in my head forever.”

Olson also earned the Coach’s Award for Hardest Working Player and participated in Best Buddies, a nonprofit organization to help create friendships with people who have developmental and intellectual disabilities, according to a statement from the university.

“Our heartfelt condolences are with Matt’s parents, family and friends as they mourn this terrible loss,” the USC statement added.
