OMAHA, Neb. (AP) – Prosecutors say a man and woman were caught on store video buying tools that police believe they later used to dismember a Nebraska woman.

Court documents unsealed Tuesday say 51-year-old Aubrey Trail told investigators that he strangled 24-year-old Sydney Loofe of Lincoln with an extension cord on Nov. 15.

Investigators believe 23-year-old Bailey Boswell helped Trail dismember Loofe, stuff her body parts in trash bags and dump them in a field near Edgar, about 90 miles southwest of Lincoln.

Loofe’s remains were found in December.

Authorities say Loofe met Boswell on an online dating app in November and they went on at least one date.

Trail and Boswell were quickly named as people of interest in the case and were arrested in late November in Branson, Missouri, on unrelated fraud charges. They have been held in the Saline County jail since then, though the charges in Loofe’s death weren’t announced until Monday.

Trail and Boswell appeared in Saline County Court on Tuesday. Each is charged with first-degree murder and improper disposal of human skeletal remains.

Authorities haven’t suggested a motive for the killing. The Nebraska Attorney General’s office, which is prosecuting the case, said it is considering seeking the death penalty.

In May, Boswell pleaded guilty in an unrelated gold coin scheme in Kansas.
