A snorkeller is feared to have died in a shark attack after his fins and badly-damaged wetsuit were found close to where he went missing. Victorian father Duncan Craw, who would have turned 33 today, went missing in waters off Surfers Way near Port MacDonnell in South Australia's south-east while on a camping trip with family on Thursday afternoon. A damaged wetsuit and flippers, believed to belong to the missing father, were found by PolAir and Police Water Operations members on Friday morning. Victorian father Duncan Craw is thought to have been the victim of a shark attack on Thursday 'It's impossible to fully explain the hole this will leave behind in the lives of all the relatives and friends who love Duncan,' Mr Craw's family wrote in a statement.
