Vital Statistics at Time of Disappearance
Details of Disappearance
Arensdorf was last seen at approximately 2:00 AM on July 4, 2001 in Dubuque, Iowa. She was at Knickers Saloon (occasionally called Knickers Tavern) in the 2180 block of Central Avenue. She was there with friends and trying to get a ride to East Dubuque, Ill. No one saw her leave the bar, and she left her car, her keys, and her money behind. She did not show up for work Thursday morning. She has never been heard from again.
Arensdorf’s family members said it was uncharacteristic of Crystal to leave without warning, and offered a $2,500 reward for information leading to her whereabouts. In October 2001 — three months after she went missing — investigators eliminated Arensdorf’s boyfriend, Tim Gerlieb, as a possible suspect in her disappearance.
Police investigated everyone who was at the bar that night. Investigators interviewed several people of interest, including a few who took and failed lie detector tests. But there has never been enough evidence to arrest anyone.
Steven and David Peacock — two former Dubuque brothers who resided in Mount Horeb, Wisconsin — were at the bar on July 4 and questioned several times in Arensdorf’s disappearance. The brothers agreed to polygraph exams in April 2002, and authorities also seized and searched David Peacock’s vehicle. The brothers were never charged in connection with Arensdorf’s case. Arensdorf has never been found. Foul play is suspected.
