A single-vehicle crash on eastbound Interstate 80 in Tooele County early Monday morning killed one man and critically injured another.
Utah Highway Patrol troopers said that about 4 a.m., 22-year-old Jeffrey Pacheaco and his 25-year-old brother, Jacob Pacheaco, were eastbound on I-80 about 20 miles west of Tooele when they lost control of their Isuzu Rodeo, which was towing a U-Haul trailer.
The Isuzu drifted off the left shoulder and then swerved back onto the road, where it began to fishtail and then rolled several times, the UHP reported.
Jeffrey Pacheaco was ejected and pronounced dead at the scene, officials said. Jacob Pacheaco also was ejected, and was flown by medical helicopter to a Salt Lake hospital in critical condition.
Neither man was wearing a seat belt, said UHP Cpl. Todd Johnson, and the investigation is ongoing as to who was driving the vehicle.
Officials have determined excessive speed was not the cause of the crash, but impaired driving is a possibility.
In the rear seat of the vehicle, a woman, Alexiss Danner, 23, and a 1-year-old child, were wearing restraints and suffered minor injuries. They also were transported to a Salt Lake hospital.
Johnson said he did not know where the group was from.
Also, the relationship between Danner and the Pacheacos was not immediately known.
