(AP Photo/Steve Ruark) (Newser) – Prosecutors have charged a 15-year-old with attempted first-degree murder and assault, and intend to try him as an adult in yesterday's shooting at Baltimore's Perry Hall School. Robert Wayne Gladden Jr. allegedly shot 17-year-old Daniel Borowy in the back in the cafeteria yesterday, before being tackled by school counselor Jesse Wasmer, the Baltimore Sun reports. "I turned around and a teacher had a kid pinned up against the vending machine," one student tells NBC Washington. "He grabbed the gun from the kid." Daniel is currently in critical condition at the Maryland Shock Trauma Center, the AP reports. About 150 students showed up for a prayer vigil on the school grounds, some wearing shirts saying, "Pray for Daniel" and "Team Wasmer." Robert allegedly brought the 12-guage shotgun to school disassembled and hidden in his backpack, sources tell WBAL 11, and he had 20 rounds of ammunition. On his Facebook page, he'd written, "First day of school, last day of my life. [Expletive] the world." His father says he was bullied.
