Horrifying new video shows moment Patriots fan, 53, leaps into the stand to confront Miami Dolphins supporter before being thumped in the side of the head and collapsing and dying

Horrifying new footage shows the moment a New England Patriots fan jumped into the stands to confront a Miami Dolphins supporter just before he was hit in the side of the head, collapsed and died.

Dale Mooney, 53, died after approaching a group of Dolphins fans who his friends said “verbally taunted” him and then punched him Sunday night at Gillette Stadium.

It all happened in the 300-story section of the stadium when something prompted Mooney to run from the aisle toward the seats and fight with other fans.

In the video, he is seen inserting himself into the crowd as some tried to break it up and others distanced themselves.

As he fought his way through, the fight broke out when Mooney’s Patriots hat fell off just before he was struck in the temple and collapsed to the ground.

Several witnesses saw Mooney struggle and collapse from a brutal punch to the temple area.

The prosecutor’s office reported that police and firefighters responded to the area where Mooney needed medical attention around 10:57 p.m.

He never returned home to his distraught wife Lisa, and she told WCVB, “Numb. I just feel numb. I can’t even believe it’s real’

Mooney, who was a season ticket holder for 30 years, was then taken to Sturdy Memorial Hospital in Attleboro, where he was pronounced dead.

He never returned home to his distraught wife Lisa, and she said WCVB: ‘Numb. I just feel numb. I can’t even believe this is real.

Lisa added: “It takes a lot to make him angry, and he has the patience of a saint. I just don’t understand what happened.

The father of two attended the game with three friends on Sunday evening.

At the stadium, first responders performed CPR on Mooney while witness Keith Noonan and his son watched it all happen.

“That’s where we got a firsthand view of these heroes doing everything they could to try to save this man’s life,” Noonan said.

In 2009, Mooney risked his life when he spotted a little girl stuck between rocks near a pier in Hampton Beach and rushed to save her.

He said Seacoastonline: ‘The waves were hitting her and she couldn’t even stand.’

The child was trying to retrieve his bodyboard, when Mooney, then 39, told the girl to jump on his shoulders as they returned to shore safely.

Gillette Stadium officials said they were heartbroken to learn what happened to the devoted fan.

“We continue to work with local authorities to assist them with their ongoing investigation. We extend our deepest sympathies and deepest condolences to Dale’s family and all those who are mourning his loss,” the stadium said in a statement.

Massachusetts State Police assigned to the Norfolk District Attorney’s Office were assigned the investigation.

Autopsy results were expected to be available Tuesday but have not yet been made public. No charges have been filed.
