Progress made in cold case

Detectives investigating the case said they had received a good response following the release last Friday of photographs of Ms Geertsema and her red Holden Torana Sunbird. Ms Geertsema was last seen leaving her family home around 10.30pm on Monday, October 23, 1978, in her 1977 red Holden Sunbird with registration AS4119.

Police believe it is unlikely the disappearance was voluntary and they can't rule out the possibility she was the victim of a crime.

Detective Senior Constable Felicity Boyd, of the Devonport Criminal Investigation Branch, said they appreciated the information provided by the public, particularly in relation to Ms Geertsema's vehicle.

Police have recently re-interviewed a number of people who were involved in Ms Geertsema's life.

Police will continue investigations and encourage anyone who has information relating to the disappearance of Ms Geertsema or about her vehicle to contact Devonport CIB on 6478 4036 or Crime Stoppers on 1800 333 000.
