A Colorado man has been charged in connection with the killing of his pregnant wife and two young daughters after the mother and their little girls went missing earlier this week. Shanann Watts, who was 15 weeks pregnant, and the couple’s daughters, Celeste, 3, and Bella, 4, were reported missing Monday by a family friend, according to police in Frederick, about 35 miles north of Denver. The FBI and the Colorado Bureau of Investigation joined local police on the missing persons case, and authorities Wednesday night announced the arrest of Watts’ husband, Chris Watts. Family friends who stood by the husband said they were shocked to hear of his arrest. Chris Watts had initially told reporters that his wife, 34, disappeared without a trace, leaving her purse and keys at home. Yesterday he confessed to killing all three of them and told authorities he could take them to where he buried the bodies. The bodies of all three females have been recovered and identified. Chris Watts, 33, was booked on three counts each of first-degree murder and tampering with physical evidence.
