WILLISTON, N.D. — A man who was attacked outside the entrance of a Williston strip club has died from his injuries, investigators said Tuesday.
Dean Niederklopfer, 25, was taken off life support at a Minot hospital late Monday, almost four days after he was attacked, Williston Detective David Peterson said. A man and woman facing charges related to the attack are jailed in South Dakota, where authorities say the pair fled after the beating outside Whispers bar.
"Dean was an innocent victim," Peterson said.
Kyle Siler, a 29-year-old former bouncer at the club, faces an aggravated assault charge, while his girlfriend, 30-year-old Jessica Gibson, faces a charge of hindering law enforcement. It wasn't immediately clear if additional charges would be filed in light of Niederklopfer's death.
Officers found Niederklopfer unconscious after being called to the scene just after midnight Friday. Witnesses told investigators that Siler had gone out his way to punch Niederklopfer. Part of the incident was caught on a security video, which also showed Gibson recording the incident on her cellphone, according to police.
Peterson declined to say what may have led up to the attack.
Local prosecutors declined comment about additional charges, and the clerk of courts said it had not yet received additional documents in the case. Siler is originally from California, but police haven't said where Gibson or Niederklopfer are from.
Siler and Gibson were arrested Friday night by a highway patrolman near Belle Fourche, South Dakota. The couple was still being held Tuesday at Meade County Jail in Sturgis as they await extradition, Peterson said.
Court documents don't list attorneys for either Siler or Gibson, and prosecutors declined to say if they had yet retained attorneys. No publicly listed phone numbers could be found for the couple.
Niederklopfer's death marked the second death stemming from violent confrontations in front of the oil boomtown's two neighboring strip clubs in the last year and a half. In March 2013, a 28-year-old Williston man was shot on the sidewalk outside the clubs after an argument. Jonathan Horvath, 46, of Idaho, was convicted in the death.
