A Los Angeles man who attended Brigham Young University-Idaho died Saturday morning as a result of injuries he suffered in an Interstate 15 crash in Blackfoot the day before.

Dalen Graham, 22, was pronounced dead at Portneuf Medical Center in Pocatello, where he was airlifted after suffering severe injuries when the 1998 Chevrolet S10 pickup he was a passenger in overturned on Interstate 15 Friday afternoon.

The driver of the pickup, Mariah N. Graham, 18, also of Los Angeles, suffered minor injuries in the crash, state police said. Mariah is Dalen’s sister and Dalen was a student at Brigham Young University-Idaho in Rexburg.

The crash occurred around 2:30 p.m. Friday while Mariah and Dalen Graham were headed southbound on the interstate in their pickup.

State police said, “(Mariah) Graham drove off of the left shoulder of the road and then returned to the road, where her vehicle began to rotate. The vehicle overturned and came to rest on its roof off of the right side of the road.”

State police did not say what caused the pickup to initially leave the left shoulder of the interstate.

Dalen Graham was airlifted from the scene via emergency helicopter to PMC.

Both Mariah and Dalen Graham were wearing their seat belts when the crash occurred, state police said.

The wreck resulted in the temporary closure of Interstate 15’s southbound lanes.

An online fundraiser has been set up to help the Grahams pay for Dalen’s medical and funeral expenses. To donate visit
