The brand new season of hit true crime podcast, Unravel, is available now. 'What Became of Jack' investigates how a fit young man disappeared from a picnic spot, leaving a trail of strange clues behind him. The belongings he left behind are discarded in a way that seems nonsensical, and to some, even sinister. Is he missing, has he left town or has there been a crime? Concern turns to suspicion and online speculation as weeks turn into months, with no sign of Jack. Now, ABC journalist Rob Burgin investigates what became of Jack, tracing the fragments of that night through a web of small Queensland towns, where everyone knows everyone, everyone knows something, but no one can agree on what became of Jack.

What Became of Jack is the latest season of the ABC's award-winning true crime podcast, Unravel. Follow Unravel to be the first to get new episodes.
