2. In OWEN EQUIPMENT & ERECTION CO. v. KROGER, 437 U.S. 365, 98 S.Ct. 2396, 57 L.Ed.2d 274 (1978), Kroger, a citizen of Iowa, brought a diversity action in Nebraska against Omaha Public Power District (OPPD), a Nebraska corporation, for the wrongful death of her husband, who was electrocuted when the beam of a steel crane, next to which he was walking, came too close to a high-tension electric line. OPPD filed a third-party claim under Federal Rule 14

(a) against the owner-operator of the crane, Owen Equipment and Erection Company, alleging that it was Owen’s negligence that had been the proximate cause.
