@nbcnewyork: A 12-year-old boy died after choking in the hallway of a Yonkers school, officials said, and now police are looking into whether it was linked to social media trend. School officials said Jacob Medina was on his way to his next class when he started showing signs of distress. The officials were not entirely sure what he was choking on, but it might have been a doughnut. The district superintendent said they tried the Heimlich maneuver, slapping his back, and eventually CPR. Nothing worked to dislodge what was in his throat, and Jacob died. Why he started choking was not immediately clear, though police were investigating whether Jacob was trying to complete a recent social media challenge. #yonkers #nbc4ny
