Michelle Cossey pleaded guilty to one count of child endangerment in September in Norristown, Pa., admitting that she had bought her son Dillon, 14, a rifle and gunpowder (which prosecutors say Dillon was planning to use in a Columbine-style attack on former classmates at Plymouth Whitemarsh High School). Michelle said she had no idea of his plans, but only wanted to help boost Dillon's "self-esteem," since he is severely overweight and had left school after the seventh-grade because of bullying.
