In this photo released by Las Vegas Metropolitan Police Dept. on Monday Aug. 1, 2011 showing Clark County Detention Center inmate Francesco Sanfilippo, 39, who was found dead with cuts on his neck and arms, and the Clark County coroner's office said he died of blunt force injuries to his head and abdomen. Suspect Carl Guilford, 18, of Las Vegas told police he killed his jail cellmate during a bloody assault with a pencil because the devil told him only one of the two men could live, according to an arrest report obtained Monday. Sanfilippo was stabbed and choked on Friday. (AP Photo/Las Vegas Metropolitan Police Dept.) less
