A 14-year-old boy planned a school attack with the help of his mother. Even if the police still don’t know if the woman knew what he was helping her son for, she was pleaded guilty for helping him build a weapon cache and of having bought a rifle and gunpowder for his troubled son.

On Tuesday in Montgomery County Court, Michele Cossey, 46, was charged of child endangerment. She admitted to have bought a rifle with a laser scope and gunpowder which her 14-year-old son used to make grenades. Dillon Cossey had a passion for the Columbine High School shooters that he decided to make an attack last year on Plymouth Whitemarsh High School.

Dillon left public school in the seventh grade because of his overweight and he was being home-schooled. His defense lawyer said that the violence which circulates over the Internet woke up the boy’s fantasies and he reached to wish for a school attack.

Christopher Parisi, Montgomery County Assistant District Attorney, said that what Michele Cossey had done was an “attempt to boost his self-esteem, and in some way help the child, as misplaced as those thoughts may have been." The woman will have to undergo a psychiatric evaluation and after three months she will be sentenced.

She may get from 3 years and a half to 7 years in prison, but her lawyer says she is possible to spend less than a year in jail. "If it were to come out that she knew he was planning an attack ... that would certainly increase the severity of the crime," Parisi said.
