Rio Tinto Kennecott Copper · Struck by falling object
All we know is a call came 10/29/08 about 8:00 a.m. that we had a fatal accident at Kennecott; our driver was killed by a pipe falling off the top of load on trailer. All Bob Orton Trucking does is haul the load (this load from WL Plastics Corp, Cedar City, Utah). We do not load or unload product.
