Martyn Tann, a diver and marine biologist who vanished after going for a swim at Mullaloo Beach in Perth in 2013, is believed to have been killed in a shark attack, a coroner tells an inquest. ABC Australia reports that Tann was last seen at Mullaloo Beach in 2013 and that the coroner’s evidence led to the view that he is dead and that a shark attack is the most likely explanation for his disappearance. The Daily Mail likewise says Tann was visiting relatives in Perth from New South Wales when he went to Mullaloo Beach and did not return. Both accounts describe the case as one in which Tann disappeared without confirmed recovery of remains, leaving the inquest to determine what likely happened. The coroner’s conclusion focuses on the likelihood of a shark-related fatality based on the circumstances presented during the proceedings, rather than on direct identification of remains.
