Katz battled alcoholism for years. The earliest known arrest occurred in 1991. About a year later, Katz was again convicted of drunk driving. Between 1994 and September 1999, Katz was arrested five times for operating after suspension or revocation of his driver's license.
Before his death, Ozaukee County Sheriff's Department had several outstanding warrants against Katz, including jumping bail and the automobile operation charges Operating While Intoxicated and Operating After Revocation.
On April 14, 2000, at the age of 37, Katz was found dead in a hotel room with an empty bottle of peppermint schnapps in his hand. A coroner's report stated his death was a result of acute pancreatic bleeding caused by chronic alcoholism.
