ST. GEORGE — A Farmington couple involved in a motorcycle crash Friday morning both have been hospitalized in critical condition.

The 62-year-old man and his 64-year-old wife were traveling south on I-15 through St. George en route to California around 10 a.m. when the accident occurred, Utah Highway Patrol Sgt. Ted Tingey said. Witnesses reported that the motorcycle was traveling in the left lane and drifted into the center median.

"The driver lost control and flipped and rolled the bike," Tingey said.

The man sustained severe internal injuries and was transported to Dixie Regional Medical Center for treatment. The woman suffered serious head trauma and was taken to University Medical Center in Las Vegas.

The driver was wearing a helmet at the time, Tingey said. It was unclear if his wife was, though a second helmet was found at the scene of the crash.

The motorcycle was the only motor vehicle involved in the accident, despite early reports that a car might also be involved. Tingey said a number of witnesses to the crash stopped to render aid and were initially believed to be part of a pile-up caused by the crash.

The incident is currently under investigation.
