Bailey Boswell, considered a person of interest in the death and disappearance of Sydney Loofe last year, pleaded not guilty Monday to a host of unrelated federal charges.
Her hearing at the federal courthouse in Lincoln marked Boswell's first appearance in open court since law enforcement officials named her and Aubrey Trail persons of interest in Loofe's death.
The pair have not been publicly accused of killing Loofe, but both face indictments accusing them in a scheme involving gold coins in which a Kansas couple were bilked out of $400,000.
In the coin scheme, Assistant U.S. Attorney Steven Russell says Trail used a pseudonym to approach his Kansas victims in November 2015, proposed they jointly buy a gold coin, sell it and share in the profits.
Trail, 51, asked the couple for money to arrange the deal for the coin that wasn't worth what he claimed, an indictment alleges.
Boswell, 23, introduced herself to the couple as a broker for the coin's sale, federal prosecutors allege.
On nine specific occasions, Trail and Boswell got the couple to drive from Hiawatha, Kansas, to Nebraska to give them gold bars and cash, according to the indictment.
Boswell faces nine felony counts, each carrying a penalty of up to 10 years imprisonment and a $250,000 fine.
Trail, who is Boswell's boyfriend, has said he expects they will also face charges in Loofe's death, although he has denied Boswell's involvement.
Investigators say Loofe, a 24-year-old who lived in Lincoln, went on a date with Boswell, whom she met on a dating app, Nov. 15.
They went back to the apartment Boswell and Trail shared in Wilber, the couple has said.
Loofe was reported missing the next day. Lincoln police named Boswell and Trail persons of interest in Loofe's disappearance in late November, and two days later, the FBI arrested them in Branson, Missouri.
Authorities found Loofe's body and evidence of foul play in rural Clay County Dec. 4.
Boswell remains in the Saline County jail in Wilber. Trail is being held in a federal prison in Leavenworth, Kansas.
Their trial is set for March 26.
