Bush and Lucy reportedly previously met online because Bush was looking for a job, and Lucy picked her up in a tan pickup truck at the Handi-Mart in Maysville to drive her to a job interview in Bentonville.
At 3 p.m. on Oct. 31, Bush reportedly texted Lucy to say she was on her way to the Handi-Mart, and she had not been heard from or seen since.
Bush was 31 weeks pregnant.
On Thursday, Nov. 3, Benton County Sheriff Shawn Holloway and Benton County District Attorney Nathan Smith spoke at a press conference and announced Bush and her child, Valkyrie Grace Willis, were found deceased.
Detectives reportedly located Valkyrie on Wednesday, Nov. 2, and Bush Nov. 3. They were both found in Missouri. Autopsies are pending, but Holloway believes the manner of the death will be gun-related.
According to Smith, the case covers several jurisdictions because Bush traveled from Arkansas and she and her child were reportedly killed in Missouri. They are facing federal charges but could also be charged locally.
The U.S. Attorney's Office said Amber used the name "Lucy" to lure Bush.
Amber reportedly told law enforcement officials she went into labor on Oct. 31 and said she delivered a stillborn. Jamie reportedly told detectives believed blood evidence found in the tan pickup truck was because of Amber going into labor.
According to the U.S. Attorney's Office, Amber kidnapped Bush and killed her "in order to claim her unborn child as her own."
