DUBUQUE, Iowa. (KWWL) --- Investigators with the Iowa state's Major Crime Unit confirmed to KWWL Monday morning that members had conducted a search at Knicker's Saloon in Dubuque on Tuesday.
Mike Krapfl, Special Agent in Charge with the Iowa Department of Criminal Investigation, said the search was part of an "ongoing investigation." No additional details are being released at this time.
Two bar employees confirmed to KWWL that investigators searched the basement of the establishment.
Knicker's Saloon issued a statement Thursday, writing in part "we have nothing to hide here." Read the full statement below:
Curtis Gerhard, a former owner of Knicker's Saloon, declined KWWL's request for comment Monday, as did one of the Saloon's two current owners. The latter referred KWWL to the Facebook statement above.
Notably, Knicker's Saloon was the last known whereabouts of Crystal Arensdorf, the subject of a prominent "cold case" that dates back to 2001.
Police say Arensdorf was last seen at the bar during the early morning hours on July 4, 2001. After she disappeared, Knicker's had been a focal point of previous investigations into what may have happened to Arensdorf.
No direct link has been made by investigators between Tuesday's search and the Arensdorf case at this time. Authorities maintain that it's an ongoing investigation, and are not releasing any additional details.
Neither state authorities, the Dubuque Police Department, nor the owners or former owners specifically ruled out the possibility that the Arensdorf case is the subject of the ongoing investigation.
