A stray bullet tragically upended a holiday party in Miami when it struck and killed a father-of-two in front of a group of panicked partygoers, dramatic video shows.

Cellphone video obtained by America TeVe shows 40-year-old Yemil Arguelles touching his chest and painfully reaching for a man sitting next to him before abruptly collapsing from a patio chair in a buddy’s backyard.

Confused guests rushed to help the man, later telling cops they thought he was going into cardiac arrest.

Arguelles was pronounced dead at Kendall Regional Medical Center.

Miami-Dade police said no one at the party fired the bullet and are still trying to figure out what happened. Detective Zubair Kahn said the bullet could have come from someone cleaning his or her gun nearby or from a random shot up into the air.

“At this point, we are basically looking at all possibilities as to how and why this could have happened,” Kahn told The Daily Mail.

Stray bullets are not unheard of in the area, a neighbor told America TeVe, saying his own house has been hit multiple times in the last few years.

“You can’t go outside at night because you can get shot,” Leonel Cobas said.
