For 15 years, Tasmania Police said the matter was investigated.

Now, after months of Right to Information requests, Badge of Betrayal has obtained 61 pages of internal investigation files that have never been publicly examined in full.

Inside those documents are admissions from police officers who contacted escort services, records showing one officer made 34 contacts with prostitutes over a two-month period, evidence that an officer lied during the investigation, and an Integrity Commission intervention that forced Tasmania Police to reopen the case.

Then, in a Badge of Betrayal exclusive, a former correctional officer who worked inside Risdon Prison speaks publicly for the first time. After listening to this podcast, they contacted us with an account of conversations they say they had with Gary Devine while he was behind bars information they reported through official prison channels years ago but have never shared publicly until now.

This is one of the most significant episodes we've released.
