A woman died and a man was in critical condition after their motorcycle collided with a car making a left-hand turn into their path Saturday in northern Utah's Box Elder County.

Killed was motorcycle passenger Heidi Thomas, 47, of Layton. She suffered severe head injuries and was pronounced dead at Tremonton Hospital, the Utah Highway Patrol reported Monday.

The motorcycle driver, Brett Thomas, 49, of Layton, was flown by helicopter to McKay-Dee Hospital in Ogden, where he remained Monday.

The motorcycle was southbound on State Route 38 near Deweyville at 6:15 p.m. Saturday, when a northbound car turned in front of the bike at the intersection with SR-102. The collision propelled both victims from the bike and onto the asphalt.

The UHP said it appeared that both the motorcycle driver and passenger were wearing helmets, but they were not full head helmets.

The driver of the car, a 50-year-old Kearns man, suffered minor injuries along with his 13-year-old son. Both treated and released at the scene. The crash, which remained under investigation, will be screened with the Box Elder County Attorney's office, UHP said.
