Family loses 'precious, much-loved man' A minute's silence at AFL semi-finals
Torn from bonds of mateship
Toxicology tests were done on McCarthy's body yesterday, although Mr Murphy stressed the results would never become public unless released by the player's immediate family.
Mr Murphy ruled out foul play as a cause of the 22-year-old's death.
"There is nothing that appears to be suspicious in nature, such as that there was no interaction in nature between two humans on this roof," he said.
"It does not appear he was with any other person."
McCarthy was found in the driveway of the Flamingo about 5.40am local time on Sunday.
Medical personnel transported him to a trauma centre where he was later pronounced dead.
