At approximately 5:50 a.m. on April 6, 1985, South Sioux City, Neb., police located a 1984 Chevy Cavalier, registered to a Ronald Zellmer, age 31, parked on the south end of the Veterans Memorial Bridge. The vehicle was left unattended with the motor running.
Sioux City Police were called to check Zellmer’s residence at 1003 Pierce Street, Apt. B-3, and found it empty with nothing unusual within the apartment.
Later the following day, Ronald’s mother Lucille was asked to come to the Sioux City Police Station where she filed a missing persons report.
Ronald was described as a 5-foot-10 white male weighing 170 pounds, with blond hair and blue eyes. He may have a mustache.
The Iowa Department of Public Safety’s Missing Person Information Clearinghouse lists his status as an involuntary disappearance.
According to family members, Ronald Zellmer was very depressed and had suffered from depression for years. A search of the Missouri River proved unsuccessful in retrieving Zellmer’s body.
The case remains open.
