The families of nine of the 26 people killed and a teacher injured at the Sandy Hook Elementary School filed a lawsuit against the manufacturer, distributor and seller of the rifle used in the shooting.
The negligence and wrongful death lawsuit, filed in Bridgeport Superior Court, asserts that the Bushmaster AR-15 rifle should not have been made publicly available because it is a military weapon unsuited for hunting or home defense, said an AP report.
"The AR-15 was specifically engineered for the United States Military to meet the needs of changing warfare," attorney Josh Koskoff said in a release. "In fact, one of the Army's specifications for the AR-15 was that it has the capability to penetrate a steel helmet."
"In addition to Bushmaster, the families have named Camfour, a firearm distributor, and Riverview Gun Sales, the store where the Bushmaster rifle was purchased in 2010," AP said.
The plaintiffs include the families of Vicki Soto, Dylan Hockley, Noah Pozner, Lauren Rousseau, Benjamin Wheeler, Jesse Lewis, Daniel Barden, Rachel P'Avino and teacher Natalie Hammond, who was injured in the shooting.
