A 14-year-old boy accused of plotting a Columbine-style attack on a Philadelphia high school today admitted illegally stockpiling weapons.

Dillon Cossey admitted three charges in juvenile court and was placed in custody until his 21st birthday.

Cossey was arrested earlier this month after trying to recruit another boy in the plan, which included chaining the doors shut at Plymouth Whitemarsh High School.

He had amassed a series of weapons, including a 9 mm semiautomatic rifle, about 30 air-powered guns modelled to look like higher-powered weapons, swords, knives, a bomb-making book, videos of the infamous 1999 Columbine high school attack in Colorado and violence-filled notebooks.

Authorities accused Cossey’s mother, Michele, of helping him build his weapons cache. She is charged with illegally buying her son a .22-calibre handgun, a .22-calibre rifle and a 9 mm semiautomatic rifle with a laser scope.
