Cold Cases

Introduction

The investigations of the disappearance of Crystal Arensdorf and the death of Kenny Joe Johnson still remain a part of CID. Investigators continue to follow up on any new leads that emerge over the years and re-examine archives, with the goal of bringing justice and closure to the families. 

Crystal Arensdorf

Crystal Ann Arensdorf, date of birth 02/01/81, was last seen during the early morning hours of July 4th, 2001 at Knicker’s Saloon, 2186 Central Avenue in Dubuque, Iowa. Earlier in the evening Crystal watched the annual fireworks display by the river, then went to Knicker’s with several friends. Family members became concerned when Crystal was not seen or heard from later in the day, which was completely out of character for her.

A missing person investigation began, which led to the follow up of hundreds of leads in the tri-state area.  All patrons in Knicker’s were identified and interviewed, and several polygraph exams were administered.  The investigation remains open.

Anyone with information about this case is urged to contact Inv Dave Randall at 563-589-4429 (email) or Inv Nick Schlosser at 563-587-3813 (email).
