Investigators are still searching for the gunmen who opened fire at a crowded basketball court in the Bronx Sunday night, wounding two men and killing a 4-year-old boy who was in the adjacent playground. The boy's grieving mother, Shianne Norman, spoke to reporters yesterday and urged witnesses to cooperate with police. “There were entirely too many people outside to not know who pulled the trigger," Norman told the Post. "Please, please, there’s no snitching when it’s a 4-year-old boy."

There were over 100 people at the basketball court for the game when gunfire erupted around 9:30 p.m. The game was organized as the “First Annual Ghetto Angels Basketball Tournament" and intended as a memorial for a 15-year-old girl who was stabbed to death one year ago—as it happens, one of the men shot, Courtney Kelly, 27, is the stabbing victim's brother. Kelly was shot in the stomach and is hospitalized in stable condition, but the Post also reports that he's been placed under his arrest for a parole violation.

No other arrests have been made, and police sources say the shooting was prompted as retaliation for a previous shooting. "A massive amount of shots just out of the blue, and then another massive amount of shots out of the blue, and then my baby was gone," the dead boy's mother tells NBC New York. Asked today about the investigation, Bloomberg told reporters, "Ray Kelly is doing his job so hopefully we’ll find out who it was. But let me point out that nothing is going to bring back the life of that child."

At a rally against violence at the basketball court yesterday, Assemblyman Erik Stevenson said the incident made him rethink his criticism to stop-and-frisk. He's now proposing legislation requiring police officers to carry metal-detecting wands, which he believes will make stop-and-frisk less invasive. "You know, when you go into a courthouse or airport, they have hand wands that do body searches, that detect metal right away, which guns are made of metal," Stevenson tells NY1. "So I think it would be better if they don't put hands on people and use these metal wands."
