The Baltimore County teen who admitted to opening fire inside Perry Hall High School on the first day of classes in August was sentenced Monday.

The judge handed 15-year-old Robert Gladden Jr. a sentence of life and suspended all but 35 years in court on Monday. The judge also called school shootings national modern-day plagues and wanted to send a message that, for those wishing to participate in similar behavior, the consequences are severe.

Gladden admitted to firing a shotgun inside a crowded cafeteria, hitting special-needs student Daniel Borowy in the back on Aug. 27, 2012 -- the first day of school.

Gladden said he was trying to make a statement that the world was messed up and he wanted to killed himself and take others with him. Gladden told the judge that taking a gun to school was "the dumbest and stupidest decision I've ever made in my life."

In court Monday, Gladden called his action senseless, begged for forgiveness and accepted the consequences. He said he did not intentionally target Borowy.
