Kevin Ellison, once one of the top defensive backs in the nation for the USC Trojans before being sidelined by a knee injury as a senior, has been arrested on federal arson charges after he reportedly told investigators he set his bed ablaze with a marijuana-filled cigar because "God" told him to. According to local media, Ellison confessed to starting a fire that engulfed an apartment early Thursday morning in Liberty Lake, Wash., near Spokane, after initially telling authorities he had been smoking in bed.
