A Colorado man was charged Monday with first-degree murder in the killings of his pregnant wife and their two young daughters, prosecutors said. Chris Watts is being held in the deaths of Shanann Watts, 34, and daughters Bella, 4, and Celeste, 3. Two additional first-degree murder charges accuse him of causing the death of a child under age 12. Watts also faces three counts of tampering with a body, and a count of first-degree unlawful termination of a pregnancy. Watts, 33, is being held without bond, with his next court appearance scheduled for Tuesday morning. Shanann, Bella and Celeste were reported missing August 13 from their home in Frederick, Colorado. Their bodies were found Thursday at the site of a petroleum and natural gas company where Chris Watts had worked.
