NORRISTOWN — A troubled teenager accused of plotting a school attack built up a stash of weapons with the help of his mother, authorities said.

Michele Cossey, 46, was arrested Friday on charges of illegally buying her home-schooled son, Dillon, a .22-caliber handgun, a .22-caliber rifle and a 9 mm semiautomatic rifle with a laser scope.

The parents were indulging the boy's interests because he was unhappy, not knowingly aiding a school assault, Montgomery County District Attorney Bruce Castor said Friday. The parents didn't know of the teen's plans, but "by virtue of her indulgence, she enabled him to get in this position," Castor said.
