A high school sophomore has been sentenced to 35 years in prison for a Maryland high school cafeteria shooting that injured a student with Down syndrome.

Deputy State's Attorney John Cox said 15-year-old Robert Gladden Jr. was sentenced Monday for the shooting at Perry Hall High School outside Baltimore last year.

Gladden pleaded guilty last week to attempted first-degree murder as part of a deal with prosecutors.

Gladden also pleaded guilty to using a firearm in a crime of violence.

Seventeen-year-old Daniel Borowy was hit in the back with a shotgun blast on the first day of classes Aug. 27. He missed more than two months of school while recuperating from his injuries.
