A shootout at a house party early Saturday left one man dead, eight people wounded and a block-long trail of bloodstains that ended in front of a public school.
"It was chaos," said Stanley Davis, who lives around the corner and awoke to the sound of police helicopters hovering overhead.
Several news sites said the party in Brooklyn's East New York neighborhood was advertised on Facebook as "Freaky Friday" and had a $5 cover charge. As many as 100 people attended, neighbors said.
Police believe the shooting began just after 3 a.m. when two people who were already in a fight bumped into each other. The gunbattle then spilled out into the street.
Wanda Ortiz, who lives a few doors from the shooting scene, said the gunshots woke her up. "About 15 in the middle of the night," Ortiz said. "I was scared, and I hit the floor."
Nine people were shot, including a 20-year-old man who was killed. Police said five shooting victims were in stable condition at area hospitals Saturday, while three were treated and released. None of the victims' names was released.
Several suspects were being questioned Saturday, police said.
