Authorities say a dispute in a Tempe mall's parking lot escalated into a shooting that left one woman with a minor injury. Police spokesman Michael Pooley says the shooting in the Arizona Mills mall lot Saturday started out as a dispute between 20 year old Voyee Smith and other males described as being in their late teens or early 20s. Pooley says Smith and another person began exchanging gunfire at a time when the lot was nearly full. A bullet grazed one of the arms of Smith's girlfriend. She refused to be taken to a hospital. No other injuries were reported. The shooting's cause is under investigation. The other suspects have not been located. Smith was taken into custody.
