Mackay detectives have today renewed their appeal for public assistance in the investigation into the 1972 disappearance and death of Marilyn Wallman in Mackay.
In 1974 a skull was located at Mt Martin, 42 kilometers from where Marilyn was last seen.
In 2014, as a result of new scientific technology, the skull was determined to be that of Marilyn Wallman and was returned to the family in January 2015.
Last week Scientific Officers, with the assistance of scientists from Brisbane and Sydney conducted an examination of the land where the remains were found, including an old privately used dump. The scientists are considering the outcome of the examinations and will provide their reports to police once completed.
Currently detectives want to speak to anyone with information relating to a motor vehicle and a watch which Marilyn was wearing when she disappeared.
Officers are seeking information in relation to the motor vehicle which was the same car determined to be of interest to police in 1972. The vehicle was described as a two-tone aqua and white HD or HR model Holden sedan (pictured).
Investigators would also like to speak to anyone with information regarding the person likely to have been using this vehicle on the morning of March 21, 1972 in the area of Wallmans Road, Eimeo and in the area of Mirani-Mt Ossa Road.
The watch Marilyn was wearing at the time of her disappearance is described as a Felicia brand wrist watch (pictured). Police are appealing to any person who may have seen a watch similar to this around the time of Marilyn’s disappearance.
Anyone with information which could assist in relation to either of these items or any other piece of information in relation to the investigation is urged to contact Crime Stoppers on 1800 333 000.
