Deadly Dallas love triangle: 1 killed in Southeast Oak Cliff shooting

A deadly Dallas love triangle is thought to be the cause of a shooting in Dallas' Southeast Oak Cliff neighborhood on Tuesday afternoon, according to an arrest affidavit.

The shooting happened just after 3 p.m. in the parking lot of the Estelle Village Apartments in the 5900 block of Highland Village Drive. 

Multiple witnesses called police about the shooting and said the suspect left in a Silver Dodge Charger. When officers arrived, they found 36-year-old Quentin Brown shot and in the parking lot. He was taken to a nearby hospital where he died. 

The affidavit shows officers had contact with the suspect and Brown minutes before the shooting happened. During that contact, officers took down the license plate number. The suspect was then identified as 22-year-old Alonzo Green.
