A former Hennepin County corrections officer indicted on weapons charges surrendered Thursday to authorities at the U.S. Courthouse in Minneapolis.

Jacquelyn Burnes, 29, who was indicted Wednesday on charges that she illegally bought guns for Twin Cities gang members, turned herself in to agents from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) a day after arrest warrants were issued for her and four others named in the straw purchase investigation.

An unidentified attorney acting on Burnes’ behalf told federal authorities on Wednesday evening that Burnes, whose whereabouts were unknown, was prepared to turn herself in Thursday. She was being held in the Ramsey County jail and will make her first court appearance Friday.

A federal indictment unsealed Wednesday accuses Burnes of buying at least three guns for Twin Cities gang members starting last winter. Within a month, one of the guns traced to Burnes was used in a shooting inside a downtown Minneapolis nightclub, according to court documents.

In addition to Burnes, the indictment names Angela Carter, 32, a Minneapolis schools employee, and three men alleged to belong to a Twin Cities gang. The federal charges include making illegal gun purchases and giving false information to a gun dealer.

On Wednesday, agents arrested Carter and two of three gang members named in the alleged conspiracy. But when they served a warrant at the home of Burnes’ parents in Osseo, agents found that Burnes had disappeared and she was declared a fugitive.

The third man indicted, Diondre Hill, 21, was already being held in the Hennepin County jail on charges related to a shooting this week that left an 8-year-old girl in critical condition. That child is the daughter of Carter, who allegedly acted in concert with Burnes to buy the guns for the gang.

Burnes, who began work as a guard at the county correctional facility last July, met Hill while he was incarcerated there, records show. By the time he was released in December, Hill and Burnes had developed a romantic relationship and Burnes started to buy the guns for him and two of his associates, according to court documents filed by federal investigators. Burnes was fired in late March after her county supervisors were notified of the investigation.
