HOUSTON --The parents of a boy who killed himself over bullying has filed a lawsuit against the Cy-Fair Independent School District. The lawsuit filed by Asher Brown's parents claimed the 13-year-old killed himself in September after repeated bullying at Hamilton Middle School. The suit accuses Cy-Fair ISD and the school of failing to protect Brown and not punishing teachers or students who bully students. The lawsuit also says the school destroyed evidence that shows Brown's father went to the school to discuss the bullying. The suit also requests "that the school adopt a policy known as Asher's Rule whereby students will be able to report issues of bullying and harassment confidentially; that the school provide a marker designating Asher's Place in the school library, where books and other materials would be made available to students dealing with bullying harassment." We called the school district for comment, but they have not returned our call.
