WILLISTON, N.D. — Prosecutors charged a man with an assault that left another man so severely injured that police said he may be declared brain-dead.
Kyle Siler was charged Saturday with aggravated assault in the beating of Dean Neiderklopfer in the early Friday morning hours in the oil boomtown of Williston, according to court documents. Police said Neiderklopfer is at Minot’s Trinity Hospital and was expected to be declared brain-dead.
Jessica Gibson, who traveled with Siler and was believed to be his girlfriend, was charged with hindering law enforcement, according to court documents.
A police affidavit said witnesses told officers that they saw Siler striking Neiderklopfer with a closed fist. Video footage seen by authorities showed Siler preparing to strike Neiderklopfer and returning to the video rubbing his hand. Witnesses told police Siler was “strutting and smirking” after the incident.
The video seen by police also showed Gibson recording the incident on her
cellphone, according to the affidavit.
Siler and Gibson fled North Dakota after the incident and were apprehended near Belle Fourche, S.D., late Friday night, according to Butte County Sheriff Fred Lamphere.
Police had tracked their cellphones going south out of North Dakota toward Belle Fourche.
Lamphere said authorities in western South Dakota were told to be on the lookout for the pair for “suspected involvement in aggravated assault and possibly a murder.” He added a highway patrolman stopped the vehicle as it was traveling south.
Lamphere said the two are about 30 years old. He added that they are being held at the Meade County Jail in Sturgis and are awaiting extradition to North Dakota.
According to the Williston police affidavit, the incident occurred on South Main Street, which is home to the town’s Amtrak station and its two strip clubs. In March 2013, a man was shot and killed in front of the side-by-side strip clubs.
Williston police did not respond to requests for information about the incident beyond what was outlined in the affidavit.
