Investigators continue to comb the murder scene at the Jefferson City prison as two inmates suspected of killing a third are held away from the general prison population. Cole County Sheriff John Hemeyer says that even though this investigation is being conducted within the walls of a prison, it still involves the solid police work needed in any murder investigation, which means gathering physical evidence and interviewing people. Guards found the body of Toby Viles in the prison ice house. The two suspected of killing him, inmates Chris Sims and Shannon Phillips, were found four days later hiding in a hole covered by a peg board.
