MESQUITE, Nev. — A stretch of Interstate 15 in northwest Arizona has been reopened after it was closed in an investigation into possible hazardous materials in a vehicle that a man carjacked and then killed himself in after robbing a Nevada bank.
The closure had shut down I-15 in both directions between Mesquite, Nev., and St. George, Utah, the Deseret News reported.
The Arizona Department of Public Safety says a man robbed a Mesquite bank on Tuesday while claiming to have a bomb.
The unidentified man drove into Arizona on I-15 but was pulled over by a state trooper.
As the trooper approached the vehicle, the suspect shot himself in the head. He died at the scene.
Authorities say the trooper noticed boxes in the car that appeared to contain hazardous materials.
