A body found in the Sheyenne River south of Warwick, North Dakota Tuesday is believed to be a 36-year-old woman missing since last fall.
Amanda Engst last had contact with her family in Breckenridge, Minnesota on Oct. 27, according to a Facebook post, which had her mother and other family members "extremely concerned." She was last seen in Warwick.
On Wednesday, authorities said the body pulled from the Sheyenne River is believed to be Engst, the Grand Forks Herald reports. A coroner will make an official identification.
Eddy County Sheriff Paul Lies said that her death appeared to be "unnatural," according to the Herald, though he did not offer more details.
Just in the past week, authorities said Engst's car was connected to robberies in Minnesota, Valley News Live reports.
It was found in the possession of Billy Joe Herman and Crystal Marie Herman, who were sentenced last month in connection with an Oct. 30 bar robbery in Buxton, North Dakota, WDAZ reported.
They couple still faces multiple charges in other robberies or burglaries at businesses in Perley, Minnesota and Grandin, North Dakota, according to the Grand Forks Herald.
Norman County Sheriff Jeremy Thornton said authorities have no reason to believe that Engst might have been involved in the robberies, according to reports, but was acquaintances with the duo, Valley News Live says.
