tomorrow classes at richneck elementary school resume for the first time since a 6-year-old student shot his teacher more than three weeks ago. they'll be restarting without their principal, their assistant principal and the school district superintendent. the principal has been reassigned and the other two have been forced out or quit since the shooting. and the environment will look a bit different when students arrive in the morning. the administration is asking parents to send their kids to school without a backpack. they'll be given a clear one instead. if a student brings their lunch, officials say all items will run through a metal detector. strict visitor protocols are already in place and even parents walking their children to school are subject to search. the school's newly assigned administrator says a police presence will be on campus to assist with this transition.
