The Baltimore County teenage who opened fire inside Perry Hall High School on the first day of school in August was sentenced on Monday.
The judge sentenced 15-year-old Robert Gladden Jr. to life in prison, and suspended all but 35 years.
Last Gladden pleaded guilty to adult charges of first-degree attempted murder.
Gladden admitted to firing a gun inside the school’s crowded cafeteria, hitting special needs student Daniel Borowy in the back.
The teen told the judge during the hearing that taking a gun to school was, “The dumbest and stupidest decision I’ve ever made in my life.”
