The Kansas Supreme Court has ruled that firearms dealers must use the "highest standard of care" to prevent selling guns to felons. The court reversed a lower court ruling holding that the owners of the Baxter Springs Gun and Pawn Shop were not liable for selling a firearm that was later used by Russell Graham to shoot himself and his son, Zeus. Graham, who had a criminal history with convictions for attempted kidnapping and attempted rape, was initially denied the sale of the gun. The gun was then sold to Graham's grandmother, Imogene Glass, who was with him. The case now goes back to district court for further proceedings.
