Aubrey Trail, 51, and Bailey Boswell, 23, are facing charges of first-degree murder and improper disposal of human skeletal remains in connection to the disappearance and murder of 24-year-old Sydney Loofe, according to the Omaha World-Herald.
Trail is representing himself.
Trail and Boswell appeared in Saline County Court on Tuesday.
In the unsealed arrest affidavit, though, investigators said Trail and Boswell were captured on video at a Home Depot in Lincoln on November 15 buying tools used to dismember Loofe, hours before her death and while she was still at work.
Despite their claims, the district attorney's office ultimately chose to charge Trail and Boswell with premeditated murder as opposed to an accidental death. She had told family members that she was planning on meeting someone she had "met online" and had reportedly spent the night with Boswell, who she had met on Tinder.
The 24-year-old's dismembered body was found stuffed in a number of garbage bags in December, three weeks after her disappearance.
Court documents reveal Trail told Federal Bureau of Investigation agents he had strangled the girl with an extension cord.
As CrimeOnline previously reported, Loofe's body was discovered in rural Clay County in early December.
Federal agents tracked down Trail and Boswell at a hotel on November 30 near Branson, Missouri, and brought them back to Nebraska on fraud indictments in a separate case. They've been held in the Saline County jail since then.
Authorities haven't suggested a motive for the killing.
Both have been charged with first degree murder and prosecutors are considering seeking the death penalty should they be found guilty. Nine days later, on February 6, he called the same reporter and told him how Loofe died: "It was suffocation", he said. Boswell also claimed the pair went on two dates which both entailed smoking marijuana together before she dropped Loofe off.
"She took to Tinder to look for that person and unfortunately, found someone that had nothing but evil plans for her."
"I haven't heard from her since", she said in a video since deleted from Facebook.
She was at his apartment, he claimed, to partake in a sexual fantasy he had about being with two women.
'It wasn't supposed to go to the extreme it went, of course not.
Before he was formally charged, Trail began calling reporters at the Omaha World-Herald, telling the story piece by piece and even expressing frustration that authorities hadn't charged him yet.
'It wasn't meant that she was to die'.
'A life for a life - that's the rules in my world.
'I should be put to death'.
