A federal judge ordered the parents of a Aurora, Colorado, theater shooting victim to pay court costs and attorney fees as a result of a lawsuit filed last year, and the defendants in the case say the family owes around a quarter of a million dollars.

According to court documents filed April 10, in a combined sum, Lucky Gunner and Sportsman Guide paid roughly $224,600 to fight allegations that they failed to properly vet the gunman who used their products to kill 12 people and injure 70 others during a screening of The Dark Knight Rises in July 2012.

BulkAmmo.com, more commonly known as Lucky Gunner, requested $151,574.70 in attorney and travel fees. And Sportsman Guide requested $73,037.87 on similar expenses.

Brian Platt, owner of BTP Arms, an online retailer that sold the gunman tear gas, has also requested $23,714.99 for attorney fees and $33,569.89 in relief.

The other defendant named in the suit, Gold Strike E Commerce LLC, an online retailer that sells body armor, has yet to file a motion.

The lawsuit was part a larger effort by the Brady Campaign to Prevent Gun Violence to expose unscrupulous gun dealers that ignore obvious warning signs and sell to customers with malicious intentions.

The plaintiffs, Sandy and Lonnie Phillips, whose daughter, 24-year-old Jessica Ghawi, was killed in the shooting, filed suit in September, but a senior district judge dismissed the claims last month.

The judge cited the Protection of Lawful Commerce in Arms Act in the ruling, a law passed in 2005 to shield gun makers and retailers from liability for injuries caused by a third party with their products.

The Brady Campaign declined Guns.com’s request for comment about paying court costs and the dismissal.
