Cockrum v C.H. Murphy/Clark-Ullman Inc. Jeffrey Cockrum and his wife sued Howmet Aerospace claiming Cockrum’s mesothelioma was caused by asbestos exposure during his employment at an Aloca plant. The trial court dismissed the Cockrums’ action because it found Howmet did not have actual knowledge that injury was certain to occur. COA #851829. King County Superior Court #22-2-12092-4 KNT.
