The Pima County Sheriff's Department wants to question a man after finding a woman dead on Tucson's south side last night.
Deputies are searching for 29-year-old Stephen J. Malone.
Deputies responded to a report of shots fired in the 4900 Block of East Butterweed Drive, near I-10 and Valencia.
25-year-old Augustina Soto was found dead inside a vehicle.
Investigators say a female passenger, who neighbors say was Soto's sister was in the vehicle and suffered non-life-threatening injuries.
Neighbors who knew Soto and Malone say they had been in a relationship since high school and have three children together.
If you know where Malone is, or if you saw anything suspicious on Butterweed Drive last night, you are urged to call 911 or 88-CRIME.
