Preliminary indications are that an icy section of roadway contributed to a crash that killed a 90-year-old Tremonton man.

Utah Highway Patrol Sgt. Todd Royce said Wednesday that troopers continued to investigate the Tuesday afternoon accident in Logan Canyon. However, motorists told UHP that the area of the Logan Canyon road where Gordon Larson's Buick LeSabre went out of control, near Temple Fork Road, was slippery at the time of the 4:20 p.m. crash.

"That's what we're going on right now, but we have no witnesses to the actual crash and so [have] no idea what happened prior to him going into the [Logan] River," Royce said.

Larson, who was heading down the canyon about 15 miles east of Logan, plunged down an embankment into the river, landing upside down.

Passers-by jumped into the river to rescue Larson, but he was already dead.

Royce said the cause of death — whether a possible medical event, the impact of the crash or perhaps drowning — was still undetermined.

Less than an hour earlier, a Honda Accord had crashed in the same location. That vehicle rolled off the road and struck a tree. Its two occupants escaped with minor injuries.
