The Utah Highway Patrol has identified two victims killed in a head-on collision that occurred on SR-112 Thursday morning.

Michael Haydon, 54, of Grantsville, and Alan Carlson, 83, of Lake Point, were traveling in a red Chevy Corsica in the westbound lane of the state road just after 11 a.m. when an eastbound Ford F-350, driven by 30-year-old Adam Smart, of Tooele, veered into their lane of travel. Witnesses said the pickup had been driving erratically. As it neared the Corsica, the Corsica tried to maneuver into the other lane of traffic to avoid hitting the pickup, but in doing so locked its breaks. At that point, the pickup swerved back into the correct lane and slammed into the Corsica head-on.

The impact left the Corsica severely mangled. Haydon, who was in the driver’s seat, was killed. Carlson, a passenger, was transported by ambulance to Mountain West Medical Center in critical condition. He later died.

The pickup went off the south side of the road and overturned. Smart, a volunteer firefighter with the Tooele City Fire Department, sustained neck and back injuries. He was transported to Mountain West and then to Intermountain Medical Center in Salt Lake City.

Lt. Troy Marx of the Utah Highway Patrol said his office is still investigating the accident, but believes alcohol to be a contributing factor in the crash. An investigating trooper reported smelling alcohol on Smart’s breath.

“There was alcohol all over the scene, but we don’t know for sure who was drinking,” Marx said. “We are waiting for blood results from both drivers.”

Marx said it usually takes a few weeks to get such blood results back from the state crime lab.
