From Braiden's coroner report -

Between 5.00 and 6.00pm on 16 July 2017 Melody was at Braiden's unit when he informed her that he was ending their relationship. Melody left but later that evening attempted to make contact with Braiden via Facebook Messenger. He did not respond.
She also tried to phone him on the land line but he did not pick up.
The next morning Melody had concerns for Braiden when he had not contacted her.
Her mother drove her to Braiden's unit. He was not inside the residence. She then entered the garage and observed Braiden suspended on a rope from a beam. He was clearly deceased.
Officers of Tasmania Police attended. They were satisfied that no suspicious circumstances attached to the death.

Post-Mortem Examination
This was carried out by pathologist, Dr Ruchira Fernando. An associated toxicology test revealed the presence of MDMA (also known as ecstasy) and benzoylecgonine, a major metabolite of cocaine. Dr Fernando confirmed the cause of death to be asphyxia
by hanging.
