Mark Duane Clewis, 41, was killed in a violent confrontation outside his Oklahoma City apartment in the spring of 2007. Known to friends and family as Doggie, he was standing and talking with two other people outside 6219 S. Independence Avenue on the evening of either April 19 or April 20 when an argument escalated into a brutal assault. Clewis was pistol-whipped, beaten, and shot, and he died at the scene.

Police identified a primary suspect, Fredrick L. Sanders, 34 at the time, and issued an arrest warrant for him; investigators also believed Sanders’s brother Marcus L. Sanders was present and that he was wanted on multiple felony warrants. Charges against a suspect that had been filed for first-degree murder were dropped on October 19, 2007, and no one else has been arrested. The Oklahoma City Police Department continues to seek information about the case.

If anyone knew Mark Clewis or has information about the events at 6219 S. Independence Avenue that night, please come forward to investigators.
