A teenager who killed a stranger with a martial arts-style kick to the head high-fived one of his friends as they ran away, leaving the man unconscious on the street. Mark Nagel, 19, was sentenced to jail today for the manslaughter of Anthony Kelly. In court, Kelly’s son expressed the pain of losing his father and the things they would never be able to do together. The family made the difficult decision to turn off Kelly’s life support, and they spoke to him while he was in a coma, not knowing if he could hear them. Nagel’s actions have caused immeasurable pain and suffering to the family, and they will never be able to reconcile with Kelly or tell him they love him again. The court heard that Nagel and his friends confronted Kelly after believing he had taken photos of them. Kelly tried to walk away, but Nagel kicked him in the face with a martial arts-style kick, causing him to lose consciousness and ultimately leading to his death. Nagel admitted to the attack and expressed remorse for his actions. The judge sentenced him to two years in prison, with the possibility of home detention. Kelly’s family released a statement remembering him as a loving father, brother, and friend, and expressing their deep loss. The community also mourns the loss of a man who gave generously of his time and was loved and respected by all who knew him.
