PHILADELPHIA—A Taiwanese exchange student accused of threatening to carry out a shooting at his suburban Philadelphia high school pleaded guilty to a federal firearms charge on Tuesday.
An-Tso Sun was arraigned in federal court, where he entered the guilty plea. A judge scheduled sentencing for December, but Sun’s attorney Robert Keller asked that the date be moved up once the pre-sentencing report is finished.
