Witnesses told police that a party of eight was arguing with the waitress over their food being cold and refused to pay. When the waitress threatened to call the police, the party walked out of the restaurant — and the waitress followed them. Arguello-Rios and another person who was seated nearby followed them outside to defend the waitress.

A witness said there was a fight — and Arguello-Rios confronted an armed woman, and tried to grab the gun.

“He was transported to an area hospital were tragically he succumbed to his injuries a short time later,” investigators stated.
