A motorcyclist suffered life-threatening injuries Friday night in a crash on Tucson's southwest side, an official said.
Shortly before 8:30 p.m., the single-vehicle crash occurred in the southbound lanes of Mission Road at Irvington Place, said Deputy Daniel Jelineo, a Pima County Sheriff's Department spokesman.
Detectives have not determined if speed or impairments were factors in the crash, Jelineo said.
No further information has been released.
