Police were searching Sunday for a gunman who opened fire the previous night by public housing in the Bedford-Stuyvesant section of Brooklyn, killing one teenager and injuring three others.
Authorities say the shooting happened at around 6:30 p.m. Saturday in front of the Marcy Houses, as a nearby youth basketball tournament was underway.
Officers arrived to find one of the tournament players, 18-year-old Mario Lopez, shot in the torso. He was pronounced dead at Woodhull Hospital.
A 13-year-old boy was shot in the neck, and by Sunday evening he was still in critical condition.
A 14-year-old boy and 15-year-old boy were in stable condition after being hit in the leg.
Andre Stephenson, the co-creator of the group Marcy On The Rise, had created the area basketball tournament three years ago to empower teens.
"I heard eight to 12 gunshots go off. I stopped everybody in the park from running out 'til we heard silence. Then you heard silence and hollering," Stephenson said. "Then I released the park, people came out to see if it was any family members of theirs that got hurt."
"I heard gunshots, a whole lot of gunshots. A young man was on the floor bleeding, one got shot in the leg, one in the neck," an eyewitness said.
Stephenson said shootings like the one on Saturday are the opposite of what his tournament stands for.
"We don't want that to be what we about here. We're doing better, we're doing what we have to do to save lives," Stephenson said.
Lopez's family members told NY1 off-camera that they were planning to celebrate Mario's graduating from high school, but now they have to plan his funeral.
A couple dozen candles were placed in the ground-floor windows of Lopez's apartment building at 24 Humboldt Street on Sunday.
Meanwhile, the father of the injured 13-year-old boy, who wished to remain anonymous, told NY1 that a bystander helped save his child's life.
"He got hit and he got up and ran, fell on the ground and somebody picked him up and put him in they car and took him to the hospital. And when they got to the hospital, he just jumped out the car holding his neck and ran in the hospital and said he was shot," the father said. "And to the person that picked him up and took him to the hospital: I love you, I appreciate you and anything I can do for you, I'm yours."
The father said his son is a fighter and will recover.
"He grabbed my wife's hand today, shook his feet. She told him that mommy's here and a tear came out his eye," the man said.
Neighbors spoke out against the senseless violence that affected four young lives.
"All this is genocide. It's wrong, this got to stop, man," one resident said.
By Sunday evening, there was still no word on a description of a suspect.
