FAWN, Pa. (AP) — A high school student who struck and seriously injured a younger teen with a crowbar after the other boy struck him with it first must stand trial on attempted homicide and aggravated assault charges. A judge made the decision Wednesday after prosecutors argued that the 17-year-old student crossed a line between self-defense and attempted homicide when he didn’t stop the March 3 street brawl in Fawn after disarming the 14-year-old. His public defender had argued his client’s actions did not rise to that level where those charges were warranted. Authorities have not said what the two boys were arguing about.
