Willie DeWayne Clark's attorney indicated that her client is a suspect in the slaying of Denver Broncos player Darrent Williams, and she needs help representing him. Alaurice Tafoya-Modi filed a motion Friday asking for co-counsel assistance because the case is "extremely difficult." But U.S. District Court Judge Boyd N. Boland denied it Monday, calling the request premature. Denver police sources have said that Clark was inside the white Chevrolet Tahoe from which the shots were fired that killed Williams in a New Year's Day drive-by. But Denver police officials have only said Clark is a "person of interest" in the Williams case and have never publicly named him as a suspect in the homicide.
