A couple who adored diving, a beautiful sunny day and a once in a lifetime dive in the great barrier reef.

It was a picture perfect Sunday for Tom and Eileen Lonergan. They had no idea that when they left the dock in a boat on the 25th January 1998, they would never return. 

Their diving gear began washing ashore weeks later, and a terrifying message was found.

We’re left with no witnesses. No bodies. Just questions.

This is the haunting story of the Lonergans.
