Michele Cossey pleaded guilty to endangering the welfare of a child after being arrested for buying her 14-year-old son guns and bomb-making material.
Police found three guns and a couple of home-made bombs in the boy's bedroom after being tipped off by the parents of one of his friends. That friend claimed her son tried to recruit him to carry out a "Columbine-style" attack on his school to get revenge on the people who bullied him over his weight.
Her son, Dillon Cossey, is sentenced to stay at a juvenile treatment facility until his 21st birthday.
As for Michele, she won't be sentenced until after a psychiatric evaluation.
