Overview
- Martyn Edward Tann, 24, went missing from Mullaloo Beach during a solo swim on April 2, 2013, and a multi-day search found no trace of him.
- Witnesses reported unusual dolphin behaviour and a moving patch of 'bubbling' water about 100 metres offshore on the day he disappeared, which police presented to the court as part of the timeline.
- About two hours after Tann entered the water a kite surfer found an unattended backpack on the beach and lifesavers used contact details from the bag to alert his family.
- A white shirt recovered about a week later had jagged cuts that a shark expert said were consistent with shark bites but could not confirm the shirt was being worn when damaged.
- Acting State Coroner Sarah Linton told the inquest the evidence satisfies her that Tann is deceased and that a shark incident is a strong possibility, and WA Police will retest a 'dreadlock type' hair sample with advanced DNA methods as the criminal inquiry continues.
