TUCSON - A 17-year-old girl has died after being hit by a car.
The Pima county Sheriff's Department identified the victim as Ruby Martinez.
Martinez passed away from her injuries Saturday.
The accident happened Friday night.
Deputies found her lying at the intersection of Nebraska Street and San Joaquin Avenue on the southwest side, near Irvington and Mission.
Detectives believe 41-year-old Denise Torres hit the girl and then drove home.
Investigators say family members convinced Torres to return to the scene later.
Torres was arrested for "leaving the scene of an accident" with serious injury.
