The sudden disappearance of a Riverland teen still unsolved 44-years on

Posted on 20/09/2019

The 21st of September 2019 marks the 44-year anniversary since the mysterious disappearance of Moorook teenager, Marilyn Qualmann.

The 14-year old had lived at Birrallee Hostel at Berri and attended Glossop High School.

On the weekends, she would return home to her parent’s home at Moorook – which is a small regional township about 8kms from Kingston-on-Murray.

On Sunday 21 September 1975, she was last seen at about 9am by her sister at their home on Moorook Rd and was reported missing the next day.

At first, there were suggestions that Marilyn had simply run away from home – she had a history of running away from home and was usually located at neighbours’ homes.

On this occasion, however, a search of the local area and subsequent widespread investigations failed to provide any indication as to her whereabouts.

There was also an exhaustive search of the River Murray at Moorook which did not assist with locating Marilyn.

Although there were some unconfirmed sightings of Marilyn at the time, there has been no contact from her since that fateful Sunday.

Likewise, no further evidence has been discovered, and police believe Marilyn may have been murdered.

A reward of up to $1,000,000 remains on offer to anyone who either provides information leading to the recovery of her remains or information leading to a conviction in the case.

Anyone with information is asked to contact Crime Stoppers on 1800 333 000 or at
