(JTA) — The family of a Jewish boy killed in the 2012 Sandy Hook Elementary School massacre is one of two families suing Newtown, Conn., and its school board for alleged lax security.

The parents of Noah Pozner, as well as Jesse Lewis, filed the lawsuit last month, the Hartford Courant reported Monday. It reportedly is seeking more than $15,000 in damages, as is standard.

According to the suit, the school board and the town were negligent in not having classroom doors that could be locked from the inside and because the school did not have a more secure entranceway, including bulletproof glass on the front windows. The lawsuit also alleges a lack of security in the parking lot.

Noah Pozner, 6, was the youngest victim of the December 2012 massacre. Twenty children and six school employees were killed when Adam Lanza, 20, forced his way into the school building and opened fire. Lanza killed himself at the school.

Prior to the school shootings Lanza, who had attended the Sandy Hook school, killed his mother, Nancy, in the Newtown home they shared.

Ten of the families, including the Pozners and Lewises, also are involved in a lawsuit against the manufacturer of the gun used in the attack, according to the Courant. The families claim that the Bushmaster AR-15 should not be sold to the public because it is a military assault weapon designed for war.
