2 brothers among 3 killed in shooting outside Glendale, Arizona, restaurant: Police
Three people -- including a teenage boy and his older brother -- were killed and five others were injured in a shooting outside a restaurant in Glendale, Arizona, according to police.
Suspects are still outstanding, Glendale police spokesperson Jose Santiago told reporters on Monday.
The Sunday evening shooting stemmed from a fight during a concert at the restaurant El Camaron Gigante, according to Glendale police.
The individuals -- who had a "history" of "bad blood" -- were escorted outside, and their fight escalated in the parking lot, Santiago said. Around 7:45 p.m., they began firing shots at each other, he said.
Three people died at the scene: a 17-year-old boy, his 29-year-old brother and a 21-year-old man, Santiago said.
Five others were injured: a 20-year-old woman, a 21-year-old woman, a 16-year-old boy, a 20-year-old man and a 23-year-old man, he said.
The 16-year-old boy was the most critically hurt; he underwent surgery overnight and is expected to recover, Santiago said.
The number of shooters was not clear but Santiago said there was more than one.
Santiago called the shooting an isolated incident and said there's no threat to the public.
