The truck driver killed when a train derailed and collapsed a bridge over Interstate 25 in Colorado has been identified as a California man. The Pueblo County coroner says the victim was 60-year-old Lafollette Henderson, of Compton. The National Transportation Safety Board announced preliminary findings Tuesday that a broken rail caused Sunday's derailment of 30 cars from a BNSF Railway train hauling coal. Coal and mangled rail cars spilled onto the highway, and the bridge collapsed as Henderson was driving underneath. I-25 is the main north-south route through Colorado. It is expected to remain closed for several more days as crews clear debris from the site.
