A fatal single-vehicle crash in Logan Canyon early Tuesday morning may have been intentional, although excessive speed and alcohol also are factors being probed, the Utah Highway Patrol confirms.

UHP Sgt. Todd Royce said the crash occurred about 12:40 a.m. on northbound Highway 89, near mile post 495, about five miles west of Garden City.

The male driver, identified as 24-year-old Matthew T. Anderson, of Logan, was not wearing a seat belt and was ejected as his Honda Accord went off a curve and smashed into the rock face of the canyon slope. Anderson was dead at the scene.

Troopers believe the Accord had crossed into the southbound lanes, apparently without trying to avoid the collision, and crashed into the rock before coming to rest on its top.

Troopers learned that the Accord and Anderson had been the subjects of an "attempt to locate" alert late Monday night.

"A call was received by law enforcement with concerns about the driver and his safety after he had called someone prior to the crash. Alcohol, speed and possible attempt to harm himself are all currently being investigated," Royce said.

No other vehicles were involved in the crash, which remained under investigation.
