A New England Patriots fan who died at a home game Sunday was punched in the head twice before the medical emergency, a witness mentioned Tuesday.

Massachusetts State Police have mentioned that Dale Mooney “suffered an apparent medical event” in the course of the fourth quarter of Sunday’s recreation towards the Miami Dolphins at Gillette Stadium in Foxborough, Mass.

“A fan in a Dolphins jersey reached over and just punched the victim twice in the face,” witness Joe Kilmartin mentioned.

Authorities had not launched a trigger or method of dying by Tuesday night time. The Norfolk District Attorney’s Office mentioned the matter stays below energetic investigation.

A spokesperson for the district lawyer’s workplace mentioned Tuesday night time there have been no arrests.

Mooney, 53, of Newmarket, New Hampshire, was a lifelong Patriots fan and a season ticket holder for 30 years, in keeping with the district lawyer’s workplace and a press release from Gillette Stadium.

“We continue to work with local authorities to assist them with their ongoing investigation,” stadium officers mentioned. “We extend our sincerest sympathies and heartfelt condolences to Dale’s family and to all those who are mourning his loss.”

An post-mortem can be carried out by the Office of the Chief Medical Examiner, Massachusetts State Police mentioned.

An NFL spokesman mentioned the group sends its deepest condolences to the family and friends of Mooney.

“Our top priority is the safety of the more than one million fans who attend games each week. We deplore the activities of a handful of fans who interfere with the enjoyment of others,” the spokesman mentioned in a press release.

The Patriots and Dolphins are in the identical division, the AFC East, and are rivals. The Dolphins received Sunday’s recreation, 24-17.
