The man who witnessed the abduction of Bronwynne Richardson and spent years trying to tell officers what he saw, fears police again aren't listening.
Wayne Leitch tried repeatedly to tell police what he saw on Smollett Street on October 12, 1973, but was effectively ignored, a 2011 coroner's inquest found.
Almost five decades on, Mr Leitch claims police still aren't listening.
When watching the airing of Crime, Lies and Alibis, Mr Leitch said he had a realisation about the significance of something he saw that night in 1973.

Mr Leitch said he contacted police and Crime Stoppers wanting to report what he realised by talking to investigators, but was left frustrated by the encounters.
He claims no one was interested in what he had to say and they had not passed his details on to investigators.
"What makes me so wild is they won't talk to me," he said.
"Why can't someone listen? I pleaded with them back then to listen, and I'm still doing it today - no one listened."
Crime Stoppers CEO Peter Price said information given to them is passed on to the operational police command to be investigated, but because the system is anonymous personal details are not passed to investigators.
He said people who wanted to provide their identity and have contact with investigators should use the non-emergency police reporting line 131 444.
NSW Police Media were contacted for comment and to verify Mr Leitch's claims, but did not respond.
Mr Leitch - who did not provide details of his revelation for fear if he does publicly it could jeopardise the police's case - said it was extremely frustrating to feel ignored by police, again.

Even after 46 years, Mr Leitch said he remembered October 12, 1973, "like yesterday" and was angry it took police so long to take him seriously.
He said moments before Bronwynne was taken, a car 'wailed' around the corner so fast he thought it might have been out of control.
"She looked at the driver and said 'oh it's you' when she recognised the driver," he said.
In the 2011 coroner's inquest into Bronwynne's death the police's response to Mr Leitch's attempts to make a statement was described as "pretty inappropriate".
He fears the new investigation might be headed in a similar direction.
