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

Maricopa County spokeswoman Cari Gerchick says 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 collapsed April 8 while walking with his wife to their car at a Scottsdale hotel and was pronounced dead at a hospital.

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

The Ultimate Warrior was one of pro wrestling’s biggest stars in the late 1980s.
