More than two decades have passed since the coronial inquest into Mark Haines' death. The family have been forgotten about — until news reporter Allan Clarke arrives in Tamworth on a routine story and becomes convinced this is a major injustice.

Allan's reporting unearths fresh information. A mother comes forward with a story about her son's involvement.

Police aren't quick to follow up. But, after a flurry of protests and phone calls … the case finally starts to gain traction.

Blood on the Tracks is the first ever series we made for Unravel, back in 2018.

But we're re-releasing it now with a new episode because the NSW Deputy State Coroner is currently holding a fresh inquest into this case.

Keep listening to the end of this series to find out about the new information that's recently been revealed in the inquest hearings.

This season of Unravel is intended to be listened to as a whole. If you haven't heard all the episodes, you shouldn't draw any conclusions, because you haven't heard all the sides of this story.
