Robert Gladden Jr., 15, stands accused of opening fire at Perry Hall High School in August, wounding a 17-year-old special needs student.
Gladden’s attorneys attempted to get the case moved to juvenile court, but the judge denied the motion.
Gladden will face 29 charges as an adult, including first-degree attempted murder.
The announcement came at the conclusion of a three-day juvenile waiver hearing that had been postponed twice. A criminal trial for Gladden in adult court remains scheduled to begin on February 19.
During closing arguments, Gladden pleaded with the court, stating that he was remorseful, that had been bullied, and that he would be best served in the juvenile system.
“My name is Bobby Gladden. I am 15 years old. I’m here today because I made the dumbest, stupidest mistake … I was not myself and I was out of my mind … people talked about me behind my back and called me a freak and a weirdo … I know that is not excuse for what I did and I am truly sorry … I want to be able to move on and I want help … I just want to make the best for myself. I know I can change. Please give me one more chance. I’m not a risk to anyone,” Gladden said.
Gladded added that he would like to meet the shooting victim and apologize to him, according to the Perry Hall Patch.
