On the late afternoon of September 24, 2017, 16-year-old Joseph Kuaffo was fatally shot in the chest inside a home on Warburton Avenue in Yonkers. Emergency services responded about 4:20 p.m.; Kuaffo was taken to a local hospital and pronounced dead.

Investigators say Kuaffo and a 17-year-old friend, Horace Allen of the Bronx, were in Kuaffo’s bedroom. Allen was reportedly showing a handgun and pointing it at a cellphone during a video call when the weapon discharged, striking the phone and Kuaffo. Allen fled the scene but later turned himself in after his mother contacted police. He was arrested and indicted on multiple felony counts, including second-degree manslaughter and weapons charges, and held without bail.

In March 2018 Allen pleaded guilty to second-degree manslaughter as part of a plea covering the other charges. Who knew Joseph or was in that neighborhood that afternoon and can shed light on what happened?
