Ghost Gate Road

The clock is ticking and psychopath Vince O'Dempsey, after so many decades of freedom, is finally held accountable for murder. Justice may be served in the McCulkin case, but countless questions remain unanswered. What of the string of missing persons - from prostitutes and low-level criminals to drug crop cooks, female backpackers and even a four-year-old child - that police think may be linked to Vince? With Vince in his 80s, it's a race against time for cold case detectives to resolve these mysteries. And finally, have we found Vince's private graveyard, and the last resting place of Barbara, Vicki and Leanne McCulkin?

Episode 8: As homicide detectives get closer to arresting Vince, he disappears deep into the Australian bush, living off the land, hiding in caves and dug-outs in and around Ghost Gate Road. Vince is finally captured and charged with the McCulkin murders, as is his accomplice Shorty Dubois. But it's still a long road to a guilty verdict, and like a trapped wild animal, Vince starts making plans to eliminate some of the witnesses who plan to testify against him.

Episode 7: Vince and his de facto, Di Pritchard, are like Australia's version of Bonnie and Clyde, keeping one step ahead of the police for years after the McCulkin triple murder. Meanwhile, more details emerge of people around Vince who have vanished. After an inquest recommends that Vince be charged with the murders, the Queensland Government declines to pursue the case in court and, once again, Vince is set free. Then forty years to that day after the McCulkin killings, two tenacious detectives decide to crack the cold case once and for all, and they set their sights on Vince.

Episode 6: Stunning revelations emerge about the possible location of Vince's almost mythical private graveyard, where he has buried his victims and visits them when it takes his fancy. Meanwhile, Vince goes on the run after the McCulkin murders and unbelievably plots another hideous multiple murder. This time he wants the girls - who saw him and his mate Shorty with the McCulkins before they disappeared in Dorchester Street - liquidated.

Episode 5: In the aftermath of the Whiskey tragedy, to that point Australia's worst mass murder, two men are arrested and charged, but did police get all of the perpetrators? Shocking new details emerge about the planning behind the Whiskey attack, and the possible involvement of corrupt police and organised crime. And one of the country's most notorious police officers lets slip a tantalising clue about Vince and the firebombing. Within 10 months of the blaze, suburban mother Barbara McCulkin and her two young daughters are taken into bushland outside Warwick and brutally murdered and raped. Why? Did Barbara and the girls die because she knew the truth behind the Whiskey?
