Former NBA All-Star Shawn Kemp is being investigated for his possible involvement in a drive-by shooting.  Police responded to reports of shots fired at a Washington state mall where two groups of people were allegedly involved in an altercation.  The groups got into two separate vehicles when one of the drivers fired several rounds at the other car.  Officers believe Kemp was either the one who fired the gun or was in the vehicle when the shots were fired.  The former Sonics player was booked into a Pierce County jail on Wednesday afternoon as police continue to investigate.
