DANBURY, Conn. (AP) — The parents of two children killed in the Sandy Hook Elementary School shooting massacre are offering to settle their wrongful death lawsuit against Newtown, Connecticut, and its school system for $5.5 million apiece.

The parents of Jesse Lewis and Noah Pozner filed the settlement offers Monday in Danbury Superior Court. A lawyer for the town and the school board declined to comment Tuesday.

The lawsuit alleges security measures at the school weren’t adequate when Adam Lanza fatally shot 20 first-graders and six educators in 2012. The other victims’ parents aren’t part of the lawsuit.

In another lawsuit, the families of nine victims and a teacher who survived are suing Madison, North Carolina-based Remington Arms, the parent company of Bushmaster Firearms, which made the semi-automatic rifle used in the shootings.
