A Duncan man accused of killing his 64-year-old roommate pleaded guilty to a manslaughter charge Tuesday. Prosecutors say James King killed Cecil Jackson in April of last year. According to Jackson's family, King was homeless, and Jackson let him and King's friend stay with him. In a written confession, King told investigators he got into a fight with Jackson and hit him two times, which led to his death. He said he then put his body in a trash can.
