Authorities have confirmed the body of Lisa Skovholt, 30, of Mooreton, North Dakota was found in Antelope Creek.
The Richland County sheriff's office said aerial surveillance, cell phone triangulation, on the ground searches and a tip from the Galchutt area all assisted with the investigation.
Skovholt's family says she was driving from Fargo, ND, home to Mooreton Friday night and was expected to arrive around 6:30 p.m. but never showed up.
The last cell phone contact was made when she was north of Galchutt, ND, but when she didn't arrive at home, a large search effort began, which included the sheriff's office, highway patrol, and fire departments from Great Bend, Dwight, and Mooreton.
Skovholt's 2001 beige Pontiac Grand Am was found in the Antelope Creek Saturday afternoon. Richland County sheriff's office are still investigating whether a medical condition may have been involved.
