A 79-year-old man was killed when his vehicle drifted off the right side of southbound Interstate 15 in Kaysville and struck the concrete support pillar of the Shepard Lane overpass, the Utah Highway Patrol says.
The victim, Byron Munsee, of Woods Cross, was the only one in the 1990 Toyota Camry when the accident occurred at 1:12 p.m. Monday.
Investigators believe, due to the circumstances of the crash, that a medical condition may have contributed to the accident.
