- Authorities in Phoenix say former pro wrestler The Ultimate Warrior died of cardiovascular disease.

Maricopa County spokeswoman Cari Gerchick said that's the finding from an autopsy conducted Thursday by the county Medical Examiner's Office.

The 54-year-old wrestler's given name was James Hellwig. He legally changed his name to his wrestling moniker in 1993.

He collapsed on April 8 while walking with his wife to their car at a Scottsdale hotel and was pronounced dead at a hospital.

Three days earlier, Warrior had been inducted into the WWE Hall of Fame at a ceremony in New Orleans. He made his first appearance on Monday Night Raw in 18 years the night before he died.

Scottsdale police have said there were no signs of foul play.

Warrior was one of pro wrestling's biggest stars in the late 1980s and early '90s. He defeated Hulk Hogan for the then WWF world title at Wrestlemania in 1990.
