Two other people were also struck by gunfire before the shooter escaped, according to police. What they're saying: Rochford's mother, Eden Rochford, told FOX 5 N.Y. that she is now preparing to bury her son while trying to stay strong for his surviving triplet siblings, Kye and Kairo. My biggest fear [was] when he [was going] to these tournaments…because these days, everybody's walking with a gun, Rochford said, recalling her final moments holding her son at the hospital. I hugged him and kissed him. At the time of his death, Rochford was working as an intake counselor for homeless families in Brooklyn with the Win organization, according to his mother. Kinu went above and beyond his duties as a Win coordinator, helping New Yorkers most in need find the path and will to build a brighter future, Win CEO Christine Quinn said in a statement. Kinu lived with purpose and his passion for helping others reached far beyond his role at Win, especially through his work across the city with children. Despite hundreds of people being present at the court when the gunfire erupted, police say few, if any, witnesses have come forward. #fox5ny #crimewatchnewyork
