Two men were killed and one injured when their vehicle rolled off the road about 5:30 a.m. Friday in Natrona County.
Brandon Calliham, 22, of Casper, and Justin R. Steele, 25, of Wichita, Kan., died, according to a Wyoming Highway Patrol media release issued Monday. Christopher Mott, 32, of Douglas, was hospitalized at the Wyoming Medical Center.
Investigators say the driver of the 1997 Ford Explorer, Steele, was coming around a curve on the Interstate 25 frontage road 8.7 miles north of Casper when the vehicle went off the road and flipped multiple times.
Steele and Mott weren't wearing seat belts. Calliham was wearing his seat belt, though not correctly, according to the release.
Investigators are looking into whether excessive speed or alcohol use played a role in the crash.
