SOUTH OGDEN — A 93-year-old man was killed and three others were injured Sunday after two cars collided on Harrison Boulevard.

The accident happened shortly after 4 p.m. at the intersection of U.S. 89 and Harrison Boulevard, where the highway transitions into Washington Boulevard. A southbound Toyota was trying to turn east on Highway 89 when a westbound Saturn crashed into the vehicle, according to South Ogden Police Sgt. Dave Labbe.

Medical personnel were stopped at the red light across the street when the accident occurred. The driver of the Saturn, a 93-year-old man, died at the scene, Labbe said. The passenger in the Saturn, a woman, 92, was critically injured and taken to a local hospital. The driver of the Toyota, a 54-year-old man, and a passenger, a 52-year-old woman, were hospitalized with injuries that did not appear to be life-threatening, Labbe said.

Investigators received reports that the driver of the Saturn had run a red light, but were not able to confirm that information, Labbe said. Police do not think that alcohol or drugs played a role in the crash. The investigation is ongoing.

Police have not yet released the names of those involved in the accident.
