She went missing from a local nightclub.

Hales led undercover police officers to her remains four years after her disappearance.

The trial began in May and had been scheduled to run four weeks.

At the heart of the Crown's case is a confession that Hales gave police. His lawyer argued that Hales had been manipulated and intimidated by the undercover officers.

But the judge ruled that he gave the information voluntarily.

While testifying, Hales was asked about his past and the night Bosse went missing.
