A march in Brooklyn to protest gun violence Saturday preceded a night full of violence.
The 4th annual Not in My Hood rally marked the beginning of Gun Violence Awareness Month across the city.
Organizers say the march is meant to teach people to take action to prevent shootings.
"The people, once they see us come through the community, through the neighborhood, it brings a sense of empowerment, that they can make a difference and make a change," said Chris Foye, whose son was killed by a stray bullet.
"We have resources inside that we hope the young people will participate in, take advantage of," said City Councilman Jumaane Williams of Brooklyn.
Among those who attended the march was Gama Droiville.
The 13-year-old was hit in the eye by a bullet as he waited for a bus back in April. Police say he was not the intended target.
A 21-year-old faces charges in connection with that shooting.
In the hours after the rally, two teens were shot in the Brownsville section of Brooklyn and four more people were shot at a block party in Crown Heights.
Police say five other shootings took place around the city overnight.
