At 8 p.m. on Thursday officers responded to a possible shooting call near Southern Avenue and Mesa Drive and found a 31-year-old man dead at the scene. The woman was treated for her injuries and released.
Four people were killed in less than half a day in suburbs east of Phoenix, police in two cities said.

Police say they are still looking for a suspect in that homicide case.
The other man, a 19-year-old, died early Friday near Stapley Drive and USA 60.
No suspects were found and the investigation is ongoing.
