A man who was shot in the lower back and his girlfriend were dropped off on South Third Avenue in South Tucson Thursday afternoon.
The girlfriend called 911 on her cellphone shortly after 3 p.m. to report the shooting, said South Tucson Police Chief Michael Ford.
Police and paramedics found the man on Third, between 30th and 29th streets, where paramedics treated the man before he was taken to a hospital, Ford said.
He was undergoing surgery Thursday night, said Ford. The man's condition was not known, he said.
A preliminary investigation revealed that the man and his girlfriend were in a car and there was a traffic altercation with another vehicle. At some point shots were fired, and the wounded man and his girlfriend were then dropped off on Third Avenue, Ford said.
He said it was not known where the traffic altercation took place.
Investigators ask that anyone with information call 911 or 88-CRIME.
