District of North Dakota Chief Judge Daniel Hovland has denied Red Fawn Fallis' request to return to a Fargo halfway house after a pretrial release violation last month.
His order came Friday, noting that Fallis was unaccounted for during an entire day and refused to answer questions about her whereabouts in that time.
Since late October, she had resided at the halfway house without incident. She is now held at the Heart of America Correctional & Treatment Center in Rugby.
She will be sentenced in late May after pleading guilty last month to federal charges of civil disorder and possession of a firearm and ammunition by a convicted felon.
As part of a plea agreement, prosecutors will move to dismiss discharge of a firearm in relation to a felony crime of violence and recommend no more than seven years at her sentencing hearing in federal court in Bismarck.
Fallis, 38, was accused of firing a handgun as officers tried to arrest her for disorderly behavior during protest activities of the Dakota Access Pipeline on Oct. 27, 2016, in southern Morton County.
