John \"J-Mac\" McCarthy of the Australian Football League\'s Port Adelaide Power died in a suspected fall from a Las Vegas hotel, a coroner\'s report said. McCarthy, a five-year veteran of the league, was in Las Vegas with 10 teammates, the Las Vegas Sun reported Tuesday. Flamingo Hotel security reported a person fell Sunday morning from a roof of the property onto a driveway, about 30 feet, a hotel spokeswoman said. The Clark County Coroner\'s Office said in a statement he died at University Medical Center and was positively identified, but said the cause and manner of death were still pending. The newspaper cited a source who said there were indications McCarthy may have jumped from the third floor of a Flamingo Hotel parking garage. \"This is a terrible tragedy for John\'s loved ones, and our deepest sympathies go out to them. It is a very sad day for the port Adelaide Football Club and the rest of the AFL industry to lose a young man in the prime of his life,\" said Andrew Demetriou, chief executive officer of the Australian Football League.
