The plaintiffs appeal the district court's grant of summary judgment. This case arises from a workplace shooting by a deranged employee who went on a violent rampage at work, killing and wounding coworkers before turning the gun on himself. The case requires us to interpret Mississippi state workers’ compensation law and decide whether the plaintiffs’ state law tort claims are barred by the Mississippi workers’ compensation law’s exclusive remedy. However, we addressed this issue in Tanks v. Lockheed Martin Corp., a case which arose from the same incident and is factually and legally indistinguishable from the case here. 417 F.3d 456 (5th Cir. 2005). In Tanks, we disagreed with the district court’s interpretation of competing lines of Mississippi cases on the subject and reversed, holding that the assaults were exclusively compensable by state workers’ compensation law. Id. at 468. Therefore, for the reasons listed in Tanks, we AFFIRM the grant of summary judgment by the district court.
