UPPER DARBY, Pa. (WTXF/AP) - A Taiwanese exchange student accused of threatening a shooting at his high school is facing a federal firearms charge.
18-year-old An-Tso Sun pleaded guilty Monday in state court to terroristic threats and was sentenced to 4 to 23 months behind bars. He immediately was paroled to federal authorities, who announced Wednesday he was charged with felony possession of ammunition while in the country on a non-immigrant visa.
School authorities were alerted in March that Sun talked about a May 1 shooting at Monsignor Bonner and Archbishop Prendergast High School, warning a friend not to go to school that day. Sun called it a joke, but prosecutors said ammunition and weapons were found in his home.
Defense attorney Robert Keller says Sun has cooperated fully and he hopes to move the case through the system quickly so Sun can return to Taiwan.
