Police have arrested Keith Little, a hospital employee, for allegedly killing Roosevelt Brockington, who was found in a basement boiler room at Suburban Hospital in Bethesda, Md., the Washington Post reports. Investigators caught a break in the case when one hospital worker saw Little using chemically treated water and a bucket to wash a pair of black gloves and a ski mask. Little, who is being held without bond in a county jail, had recently received a poor performance review from Brockington, whom he allegedly stabbed many times. The review prevented him from getting a raise. Article
