Nine months after Mark's death, an inquest is held. The family are hopeful it will give them answers, but the police won't budge from their theory that he put himself on the tracks.

As the hearing unfolds, the family find out just how mediocre the initial investigation was.

One person is in the family's corner though. The railway worker who found Mark on the tracks is adamant the police and the forensic pathologist have it wrong. He's remained silent for the last thirty years but finally comes forward to set the record straight.

On the surface, Tamworth in 1988 is a typical Aussie town with rodeos, farmers and an active Country Women's Association. But beneath the friendly veneer, there's a thriving criminal underbelly. Large marijuana crops grow on the outskirts of town and there are reports of bikie gangs with links to corrupt cops on the take.

The police investigation into Mark's death has stalled, allowing gossip and innuendo to take hold. The family know Mark occasionally smoked marijuana, but now they're hearing whispers that he might've got on the wrong side of some serious criminals.

The family decide to confront a man rumoured to have been involved… with ugly consequences.

When Mark Haines dies, news of the teenager's death spreads quickly through Tamworth and beyond. His family are on summer holidays in different parts of the state and rush home to be together in grief.

While the family mourns and Mark's body is in the morgue, their town is in full party mode. The Tamworth Country Music Festival is on and Australia is celebrating 200 years of colonisation. For Mark's uncles, it feels like the death of a young Aboriginal boy is the last thing on anyone's mind.

The police come up with a theory that Mark might've killed himself … but the family aren't buying it. In the days and weeks ahead, his uncles return repeatedly to the train tracks looking for answers. They're worried the police have missed vital clues and they become convinced Mark met with foul play.

In their quest to disprove the police theory, the family find an unlikely ally. The railway worker who first found Mark's body on tracks is just as convinced the evidence out there on the tracks just doesn't add up.

Just outside Australia's country music capital, a young man's body is found on the train tracks, surrounded by shattered Christmas presents and discarded wrapping paper.

For decades, the mystery has haunted Tamworth. 

After Unravel's first season Blood on the Tracks brought national attention to the case and won a Walkley award, a new inquest was launched.

Now, Muruwari and Gomeroi journalist Allan Clarke returns to where it all began for Unravel, revisiting Tamworth and uncovering what's happened since, as the long-awaited final chapter of the story unfolds, and major new revelations are heard at the inquest.

But before then, let's return to episode one. We trace Mark's movements on the night before his death, as he hit the town on a big night out with a bunch of friends, dancing, drinking and having fun. Mark's friends and girlfriend say they left him in the early hours. Just after, a nearby resident hears voices on the street, what sounds like an argument, and a car driving dangerously.

But the next few hours remain a mystery. How did Mark end up on the tracks?

Back in 2018, our first season Blood on the Tracks investigated the suspicious death of 17-year-old Mark Haines, whose body was found on the railway line outside Tamworth in January 1988.

Since Allan Clarke first reported this story, there's been a fresh inquest, with new witnesses and explosive allegations.

Dive back into Blood on the Tracks. We're republishing the original series plus a brand new episode, where we delve into the latest from the new inquest.

Go behind the scenes of the podcast with reporter Alicia Bridges, who answers questions about how she investigated Mr Big.

Asking the hard questions is Rachael Brown, the host of the ABC's first true crime podcast, Trace.

They discuss some of the challenges and dilemmas around reporting on the story, how Alicia came across the case, and some of the things that didn't make it in to the podcast.

As Alicia Bridges investigates the beginnings of an epic deception, she finds it spans across continents. At the heart of the deception is an upside-down world of gang crime, and a series of dilemmas. What secrets should stay secret? How far would you go to catch a killer?

One man is in jail, convicted for murder. But are there other people behind bars who might be innocent, here or overseas? In Canada, a secret recording captures another man admitting to murder, and the same story begins again, but this time with a different ending.

In this case, Andy Rose is under suspicion for the murder of two German travellers, Andrea Scherpf and Bernd Göricke.

His lawyer Tania Chamberlain recounts her shock at the contents of a VHS tape that arrives at her office one day. Eventually, the issue ends up in the Canada's highest court, and one of the country's highest-profile litigators, Marie Heinen, gets involved.

Back in Melbourne, Mary Cook's daughters speak about what happened to their mother, and give their thoughts on everything that followed.

STATEMENT FROM VICTORIA POLICE:

Victoria Police stands behind the rigorous investigation which led to the conviction of Glen Weaven in relation to the 2008 death of Mary Lou Cook in Narre Warren. We consider this matter finalised and will not be commenting further.

Victoria Police does not comment on the specifics or application of covert methodology. Covert methodology is deployed in the investigation of the most serious and violent crimes, and it is incumbent on law enforcement to pursue strategies to seek justice for victims and their families. Community safety is at the forefront of all decision making.

Investigative strategies involving serious and organised crime whether covert or overt, are subject to significant planning and risk assessment processes. Victoria Police applies internal operating procedures to covert investigations, which include strict parameters and risk assessment processes including consideration of human rights. The deployments are also subject to formal reporting and oversight regimes to ensure they are employed appropriately and do not adversely impact future court proceedings or investigations.

Victoria Police monitors the use of covert strategies in other Australian jurisdictions and around the world, to ensure our methods remain contemporary and that they align with best practice. Victoria Police accepts that covert methods are and have been subject to public discussion and interest due to judicial proceedings and media reporting, however further publicity does not benefit current or future application of the strategies.

It is important to note that while the concepts of covert methods may be in the public realm at various times, the details pertaining to the practical application are not. All investigations whether covert or overt vary and the mechanisms employed change depending on the circumstances at the time.

Success or results in terms of covert strategies is difficult to quantify. The methodology is employed as an investigative strategy with the aim of seeking answers and to identify the person or persons responsible for serious criminal offending. The outcome may not result in a criminal conviction but that does not mean there is not a result.

STATEMENT FROM QUEENSLAND POLICE:

The Queensland Police Service is committed to high standards of behaviour, transparency and accountability.

Our purpose is to keep people, places and communities of Queensland safe through excellence in policing and community safety. To achieve this, investigators employ numerous lawful strategies for investigating and solving all crimes. These strategies can at times include covert methodologies to progress investigations, which under all circumstances should remain covert to protect their effectiveness.

As with every investigation, investigators continuously review current investigative strategies, techniques and emerging trends to ensure such methods do not impede the solving of a crime.
