Student’s mother pleads guilty in plot at Plymouth Whitemarsh High School:

Michele Cossey pleaded guilty in court yesterday to charges of endangering the welfare of children. Cossey was arrested for supplying her son, Dillon Cossey, with illegal firearms that she purchased.

Dillon Cossey was arrested last year for plotting an attack against Plymouth-Whitemarsh High School outside of Philadelphia even though he had been homeschooled for over a year.

A sentencing date has not been set yet.
