Appeal focuses on Newtown officials' actions before shooting

HARTFORD, Conn. (AP) -- A Connecticut appeals court is set to hear arguments in a lawsuit alleging Sandy Hook Elementary School officials failed to order a lockdown that could have saved lives before a gunman killed 20 first-graders and six educators in 2012.

The hearing before the state Appellate Court is scheduled for Wednesday afternoon.

The parents of two children killed at the Newtown school are appealing the dismissal of their lawsuit by a trial court judge, who ruled school officials were immune from being sued and security protocols were discretionary. The parents are seeking undisclosed damages and hope the case results in safety procedures being followed in the future.

A lawyer for the town and school district has said there is no evidence school officials did anything wrong.
