“Mostly vocal but I absolutely saw a guy throw one vicious punch that knocked the victim out. He was unresponsive for a good 4-5 minutes before medical arrived," they said. "They did compressions for at least 10 minutes before they transported him on a backboard. It was horrific to watch."
Mooney's wife Lisa told the outlet that “according to stadium footage Dale never threw a punch," and expressed that he was a lifelong fan of the Patriots and had been a season ticket holder for 30 years.
While speaking to WHDH, she added that Mooney was self-employed. As per his health, she shared that Mooney had no known heart conditions but had a father who "had issues with his heart."
