A Colorado man was charged Monday with first-degree murder in the killings of his pregnant wife and their two young daughters, according to court papers.
Chris Watts is charged in the deaths of Shanann Watts, 34, and daughters, Bella, 4, and Celeste, 3.
Watts also faces three counts of tampering with a body, and a count of first-degree unlawful termination of a pregnancy, according to court filings in Weld County.
Officials were planning an afternoon news conference in the case.
Watts, 33, is being held without bond, with his next court appearance scheduled for Tuesday.

Shanann, Bella and Celeste were reported missing last Monday from their home in Frederick, a town of about 8,600 people 30 miles north of Denver.
Their bodies were found Thursday at the site of a petroleum and natural gas company where Chris Watts had worked, authorities said.
A court filing by prosecutors says Shanann Watts’ body was “recovered from a shallow grave near an oil tank,” and that “law enforcement recovered the bodies of defendant’s two daughters from inside oil tanks located near the grave of their mother.”
Prosecutors have not provided a motive in the killings.
A judge sealed the arrest affidavit, which might provide information about why Chris Watts was arrested and other details.
