MILWAUKEE (WKOW) -- More than 16 years after being beaten at Summerfest, 49-year-old Joseph Hetzel has died.
Hetzel died at a rehabilitation center in Fond du Lac February 28. The Milwaukee County medical examiner has ruled his death a homicide.
Hetzel's brother, Todd, told an investigator his brother was beaten by about five men in a parking lot fight at Milwaukee's Summerfest in 1996. No arrests were ever made.
Joseph Hetzel was left paralyzed on one side and had a severe brain injury. Todd says his brother suffered another brain injury when he fell down some stairs in Hartford in 2009.
The medical examiner ruled Hetzel died of complications of blunt force injuries to his head.
