An investigation is underway into what led to a shootout at an Opa-locka party Saturday night where two were killed and more than 30 shots were fired.

The shooting began at around 10:45 p.m. in the area of Northwest 151st Street and 18th Avenue, said Antonio Sanchez, a deputy chief with the Opa-locka police.

Sanchez said officers arrived to a chaotic scene.

“We encountered multiple gunshot victims,” Sanchez said. Two victims died at the scene; four others were wounded.

According to witnesses, a crowd had gathered to remember a friend who had died and celebrate another’s birthday. One female partygoer said the celebration was underway when the first shots rang out.

“Everybody started running, we didn’t know who was shooting or why they were shooting...it was just crazy,” said the woman who did not give her name to Miami Herald newspartner CBS4-Miami.

The woman said she heard between 30 to 40 gunshots fired in a span of 10 and 15 minutes. She took cover under a car until the shooting stopped.

The area where the shooting took place is inside “The Triangle” where a number of shootings have occurred over the last two decades.

Police have not released the names of the dead or the wounded.
