Staff at a Gold Coast hotel are assisting police investigating the death of a man whose ex-girlfriend was found dead in Sydney this week.
Police were about to arrest Elliot Coulson, 32, when he fell 26 floors to his death at the Surfers Paradise Marriott Resort and Spa shortly after midday local time on Wednesday.
A routine investigation by the ethical standards command overseen by the coroner is believed to be underway because of police officers' proximity to the death.
Coulson, a combat systems officer with the Australian Navy, was wanted for questioning over the suspicious death of Kate Malonyay, 32, found dead in her Mosman unit on Monday.
It is not clear if Coulson intended to fall or was trying to move to another floor to evade police. Police have confirmed he was in Sydney in recent days.
