A man died after being pinned between two semitrailer trucks in southwestern Nebraska over the weekend, authorities there said. The accident happened Sunday in Wauneta, killing Brian Stute, 54, of Benkelman, the Omaha World-Herald reported. The Nebraska State Patrol said Stute had parked his semi at a grain elevator to unload and was at the rear of the trailer when the driver of another semi parked behind his. When the other driver got out to talk to Stute, the rig rolled down a slope and pinned Stute, investigators said. Stute was taken to a nearby hospital, where he was pronounced dead. The patrol is investigating.
