At 6:27 a.m. on his first day as a sophomore at Perry Hall High School in the Baltimore suburbs, Robert Wayne Gladden Jr. updated his Facebook status.
"First day of school, last day of my life," he wrote. He then typed a symbol resembling a person with two middle fingers extended before adding "f--- the world."
Gladden, a pale youth with long, dark hair who turned 15 just three weeks ago, has been charged as an adult in the shooting of a 17-year-old classmate, who was hit in the back with a shotgun blast in the school's cafeteria Monday morning. The victim, Daniel Borowy, remained in critical condition Tuesday afternoon.
