Former professional wrestling star Jimmy “Superfly” Snuka has pleaded not guilty to third-degree murder charges in the death of his mistress more than three decades ago.

Snuka, 72, was arraigned Monday in Lehigh County Court in Allentown. His girlfriend, 23-year-old Nancy Argentino of New York, was found dead in May 1983 after authorities were called to a Whitehall Township hotel room she was sharing with Snuka. Defence attorney Robert Kirwan II has called her death an “unfortunate accident.”

At his court appearance, Snuka did not appear to know the day of the week, how to read or write english, or the location of the courthouse, according to to reports. His attorney said the the former entertainer has early-onset dementia and post-concussion syndrome. Snuka told the judge he can’t read or write English.

The judge issued a gag order in the case.
