HERNANDO, MS - The federal Occupational Safety and Health Administration is helping investigate the collapse of six concrete steel-reinforced beams that killed a man in Mississippi.
The beams, 98 feet long and weighing 40,000 pounds each, fell Monday. They crushed 20-year-old Jerrell Robinson's vehicle and killed him instantly.
A trackhoe, operated by 38-year-old Marty Rakestraw of Dumas, may have knocked into the beams and sent them tumbling. Rakestraw worked for a contractor on the project, Memphis-based Ronald S. Terry Construction.
The Mississippi Department of Transportation is not conducting a separate investigation, says Danny Walker, a district construction engineer.
The beams were resting on top of two columns on each side of U.S. 51. They were not secured at this stage of construction.
