Four armed men with white bandannas covering their faces opened fire at a party early Sunday, killing two people and injuring five others, police said.
Authorities were searching for the suspects, and the shootings were believed to be gang related, police said.
About 300 people were attending the graduation and birthday party that began Saturday night and continued into the early morning at the Polish American Club in Miami.
At about 1 a.m., the four gunmen entered the party and began arguing with people, police said. They then started shooting, hitting people ages 15 to 20, police said.
A 16-year-old and a 20-year-old died inside the rented hall, The Miami Herald reported. The other injured guests were taken to hospitals. One was listed in critical condition Sunday. The rest were in stable condition, police said.
Kevin Garvey, a club employee, said he saw a young man lying in a pool of blood by the bathroom and two more wounded teens on the dance floor — a boy shot in the abdomen and a girl shot in the back.
“It was complete pandemonium. Everyone was ducking and hitting the ground,” Garvey said. “There were chairs flying in the air, and people screaming. I have never seen anything like that in my life.”
Miami police did not immediately return a phone call to The Associated Press on Sunday night.
