SAN BERNARDINO (CBSLA) — One motorcyclist was shot and killed and a second has been hospitalized Friday after gunfire erupted on the 210 Freeway in San Bernardino, which has been closed until further notice.

Officers responding to the eastbound 210 Freeway at the 215 just before 4 a.m. discovered the two riders laying in lanes when they arrived. Shawn Fowler, 44, of Utah, was riding with his wife when they stopped for a mechanical problem.

Fowler was declared dead at the scene. His wife was not injured.

The second man was shot in the shoulder and was taken to a hospital in critical condition, but he is expected to survive.

The trio, who wore clothes with insignia indicating they were part of a motorcycle club, were reportedly on a road trip to Mexico. Investigators are looking into the possibility that they were part of an outlaw biker gang.

The eastbound lanes were shut down until about 11:15 a.m.
