Shocking video shows Connecticut dad Paul Kueker jumped to his death at a weekend concert at Madison Square Garden — with witnesses telling cops he appeared “intoxicated,’’ law-enforcement sources said Monday.

The 51-year-old married father of two, who was celebrating his 25th wedding anniversary with his wife at Saturday’s Goose concert, was  captured  in the footage taking a head-first dive from a balcony about 150 up — landing on fellow concertgoers below.

He “appeared intoxicated” and “under the influence’’ before he took the horrifying leap over the 4-foot glass barrier  from the seating section in the 300s  shortly before 10 p.m., law-enforcement sources said, quoting witnesses.

Several people who he landed on only suffered minor injuries, other sources said.

Kueker was “unconscious and unresponsive” after striking the ground, police said.

He was rushed to Bellevue Hospital, where he was pronounced dead.

Sources said Kueker’s wife was seated three sections away, in their assigned seats, when her husband jumped.

She was unaware of what happened until officials told her.

The tragic man’s wife thought her husband had gone to the bathroom, kin have said.

Kueker’s family declined comment to The Post at their home earlier Monday and did not return a call later seeking comment on the video and witness accounts.

The city  medical examiner’s office said Monday that the cause of Kueker’s death remains under investigation. It was conducting a toxicology report as part of its probe.

“While we await the police report on the tragedy at last night’s Goose concert, we are deeply saddened by the loss of a fan’s life at Madison Square Garden,” MSG said in a statement.

“Our hearts go out to the family and friends of the concertgoer.”

The incident is eerily similar to a 2022 incident during a performance by the jam band Phish, when a fan took a running start and a leap off a balcony.

The man survived but was left paralyzed.
