NEW YORK (CNN) -- A male New York Jets fan who punched a female New England Patriots fan following Sunday's overtime football game at MetLife Stadium spent three years in jail for stabbing a teenager to death in a fight nearly two decades ago.
A video of the incident made its way to YouTube and Deadspin, where it quickly made headlines. A commentator on Deadspin said the fight started over a rivalry between the fans of the opposing teams, the New York Post reported. The Jets won the game 30-27.
Kurt Paschke II, now 38, was convicted of negligent homicide in 1995 after fatally stabbing 17-year-old Henry Ferrer in a fight behind a pizzeria, according to records from the Suffolk County District Attorney's office. He's now a Long Island bartender.
Paschke was released after serving 3 years, and placed on parole. He has been arrested twice since then, both times for disorderly conduct.
Colleen Paschke told CNN affiliate WCBS that her son was "set up by a white supremacy group, and unfortunately, he ended up taking the blame for the stabbing of another youth."
The video of the altercation shows Paschke being pulled away from a fight. A blonde woman then steps forward to confront him, and Paschke punches her on the left side of her head. It also appears that a bystander hit Paschke in response.
The Jets said the matter has been turned over to authorities.
"We are aware of the situation and we do not tolerate that behavior," a team spokesman said. "Parties involved were detained and this matter is now in the hands of the New Jersey State Police."
Paschke's mother suggested the woman was the aggressor and he acted in self-defense.
"If the girl is going to be out of control like that, why can't a guy defend himself?" she told CNN affiliate News 12 Long Island. "These girls are today, they're really out of control. I really think that they think they are protected because they are girls and think they can get away with anything."
Paschke's mother also said that her son suffered a concussion and lacerations to his head after she hit him several times. The view of the brawl is obscured as the woman approaches Paschke.
