New 'theory' on drowned doctor's last moments
PREMILINARY autopsy results of Gemma Diessel's body have returned more than a week after she was found dead on Dicky Beach.
Caloundra CIB Detective Senior Constable Russell Connor said the early results delivered to police showed "nothing suspicious".
"It's an ongoing investigation, but the results weren't alarming," he said.
"We are also awaiting further toxicology results which could be weeks away," he said.
Dr Diessel, 27, was just four weeks into her new career as a doctor of medicine at the Sunshine Coast University Hospital when she was found by a surfer at Dicky Beach, Caloundra on February 14.
Police believe she drowned after getting into trouble during a midnight swim. Dr Diessel reportedly loved Dicky Beach.
Her car and belongings were found unlocked 500m from where her body was found.
Police were still searching for her phone, a black Samsung S9 which may hold the key to her final movements.
Det Snr Cst Connor said while there were no sign of the phone, police had another theory.
"We have been doing our own electronic checks," he said.
"We have a theory that she has taken the towel and phone down to the beach and the tide has taken it away as it rose through the night."
Her sister, Tanya Diessel paid tribute to her saying she was the was the best little sister that anyone could have.
"She achieved more than what most people achieve in their whole life," Tanya said.
