On Monday, Trail and Boswell were charged with first-degree murder and abandoning of human skeletal remains, and on Tuesday prosecutors released court documents detailing Loofe's disappearance and the investigation of her death.
During a February interview with the Omaha World-Herald Trail said that Loofe was a willing participant in a sexual fantasy with himself and two other women. And the purchase was made hours before Loofe's death, while she was still at work and unaware of the grisly fate that awaited her.
Loofe, 24, had met Boswell on the dating app Tinder.
Prosecutors in the case include Saline County Attorney Tad Eickmann and special appointed prosecutors from the Nebraska Attorney General's Office, Michael Guinan and Corey O'Brien.
Sydney Loofe just had to get through her shift at Menards and then it would be date night.
Police say Sydney was abused and strangled to death with an extension cord before her body was chopped up and dumped.
Partial remains of Loofe were found in Clay County, December 4.
Both Trail and Boswell were persons of interest early on in Loofe's disappearance and arrested on November 30, the Journal-Star reported.
But on November 16, Loofe didn't show up for work at Menard's in north Lincoln or respond to family members who attempted to contact her, the Lincoln Journal-Star reported.
The last message Boswell sent through Tinder to Loofe was on the 15th at 6:54 p.m., telling Loofe she was at her home.
Her body was discovered by the Federal Bureau of Investigation on December 5, and meanwhile Boswell and Trail are accused of handling stolen goods.
The released court documents say Trail told an Federal Bureau of Investigation special agent that he strangled Loofe with an extension cord, KETV reported.
In court documents, investigators also said a security video from a Lincoln Home Depot show Trail and Boswell buying tools that were used to dismember Loofe, according to KETV.
Two suspects in the death of Sydney Loofe, of Lincoln, today were ordered held without bond by Saline County Judge Linda Bauer.
He told the Omaha World-Herald: 'It wasn't supposed to go to the extreme it went, of course not. "It wasn't meant that she was to die".
"A life for a life - that's the rules in my world", Trail told the World-Herald in January.
During Trail and Boswell's first court appearance, however, more information regarding Loofe's murder was given, including that she had been strangled with an extension cord and her body had been dismembered and found in several places. That happened hours before Loofe was seen leaving her job at Menards on November 15. Boswell said in the video she and Loofe did drugs at her house before she dropped Loofe off at a friend's house.
