A Huachuca City woman was killed and a Sierra Vista man remains in a hospital after a head-on vehicle crash in Sierra Vista Tuesday, police say.
At about 6 a.m., Sierra Vista police officers responded to a collision on Highway 90 at Airport Road, where two vehicles with "extensive front-end damage" were blocking northbound travel.
Witnesses told police that a Pontiac minivan driven by Lisa Martinez, 40, crossed the center line and struck the man's Buick sedan, according to a police news release.
Martinez was pronounced dead at the scene and the 66-year-old man was flown to a Tucson hospital.
Detectives have not determined if impairments were a factor in the incident, the news release said.
The crash investigation is ongoing.
