A Missouri woman charged with the fatal kidnapping of a pregnant woman whose baby she allegedly planned to claim as her own has been charged with the death of the fetus, federal court records show.
A grand jury has charged Amber Waterman, 43, with kidnapping resulting in the death of Valkyrie Grace Willis, according to an indictment filed Tuesday in U.S. District Court in Missouri.
Waterman was charged in November with the fatal kidnapping of 33-year-old Ashley Bush. Bush, of Benton County, Arkansas, was 31 weeks pregnant when she was found dead Nov. 3.
Authorities said Bush appeared to have been shot. Her remains were discovered in Missouri, in a different location from the fetus.
Waterman’s husband, Jamie Waterman, 43, has already been charged with one count of aiding his wife in the alleged kidnapping and preventing her arrest.
Amber Waterman faces life in prison if convicted. Her husband faces a maximum prison sentence of 15 years. Both pleaded not guilty.
The Watermans’ attorneys did not immediately respond to requests for comment.
Federal authorities said Amber Waterman, of Pineville, Missouri, posed as a woman named “Lucy” and allegedly tricked Bush into believing she was meeting with a work supervisor on Oct. 31.
Prior to her arrest, Amber Waterman denied knowing Bush, according to an affidavit in support of her arrest. In an interview with authorities at her home, she said she gave birth to a stillborn baby on October 31, the day Bush was reported missing, according to the affidavit.
Jamie Waterman told authorities his wife burned Bush’s body at a fire pit and confessed to the murder, the affidavit states. Jamie Waterman added that she later blamed the death on Lucy, who she described as a former co-worker at Walmart, according to the affidavit.
