Disappearance of Trudie Adams

Trudie Jeanette Adams disappeared in the early hours of 25 June 1978 after attending a dance at the Newport Surf Life Saving Club, New South Wales, Australia. She left the event early before hitchhiking home, at which point she entered a vehicle on Barrenjoey Road and has not been seen since. Her disappearance is significant in that it sparked New South Wales' biggest missing person search at the time, sparked extensive and ongoing national media attention, and eventually a A$250,000 reward.

Trudie Adams' parents and ex-boyfriend, Steven Norris, reported her missing on 25 June 1978 after she failed to arrive home from the dance. Although police initially believed that the car she entered was a green Kombi van, Norris, as the main eyewitness, stated that he saw her enter a light-coloured 1977 Holden panel van. Police who investigated the case originally cast suspicion on Norris. Eventually he was cleared, and suspicion widened to those involved in the drug scene.

In the days after the attacks, a number of female rape victims, who had been assaulted by two disguised men, began to report a series of then-unknown crimes to police. Investigators then suspected that Adams' disappearance was linked to the 14 now-known violent rapes that had occurred in the Northern Beaches between 1971 and 1978, and may also be related to an attempted attack on a hitchhiker earlier on the evening of Adams' disappearance. On 16 August 1978, a reward of A$20,000 was offered by the New South Wales government, and over the years her suspected murder has been investigated by police four times.
