"It's very early in our investigation," she said. "I'm not sure how it occurred. We're investigating it now. I don't know if they were all outside standing, some in a car, some not in a car. I don't know that yet."

The station reports police set up at least 37 markers indicating bullet casings on the street and on a staircase of the complex.

Some victims walked into the hospital on their own, Burden said. "We have some that were driven by friends and some that were actually transported by fire and rescue," she said.

Miami Fire Rescue Lt. Ignatius Carroll told reporters a large crowd was at the scene when rescue units arrived. He described an "emotional scene outside with family members crowding around."

There was no word on a motive in the shooting, the conditions of the injured or possible arrests.
