A close friend to a police officer who vanished into thin air has revealed the final conversation she had with him before he was declared missing. Popular cop Jay Notaro, from Queensland, Australia , disappeared off the coast of Broken Head Beach in Byron Bay, just one day after his 45th birthday. His loved ones were left in mourning after the cop vanished on March 25. His surfboard was discovered with the leg rope attached at the beach - with his car being located a mere 500 metres away in the car park. Dozens of theories have emerged, but there is still no concrete answer as to what happened to him. On Friday, a heartfelt memorial service was held by Queensland Police in Brisbane, where his friend Claire Campbell spoke about her last words with Mr Notaro. She had phoned him to sing happy birthday, before forwarding videos of her two sons playing touch footy, a type of league rugby, reports News AU . Mr Notaro, who played for the Queensland Police Service Rugby League side, responded to the footage with one word. His pal revealed: “Jay’s last ever text message in response to those clips was just one word: ‘FLYING!!’ “The next day, we learned that Jay too, was flying sky high, heaven-bound to rest in peace forevermore." She added: "And just as we said to Jay at the end of that birthday call, the last call that he ever answered today we say Jay, we love you. We miss you.” QPS Chaplin Jeff Baills, who led the service, said: “I have heard many scenarios, reasons, hypotheses, explanations, as to why this happened. What we do know that happened is where his Apple watch last pinged and where his surfboard was found. Everything else is speculation. We may never actually know for certain how this happened.”
