The Clay County Sheriff's Office is investigating an apparent fatal workplace accident in Randolph, MO.

Deputies were dispatched on a medical call at 4:58 pm, Monday, January 30, to Martin Marietta Materials located at 401 Randolph Road. An employee of the business, 42-year-old Bobby Joe Allen of Gladstone, MO, had fallen three to four stories from a catwalk, landing on rocks. Allen was unresponsive after the fall.

EMS arrived on scene shortly before deputies and declared Allen deceased. Deputies were not able to locate any witnesses to the fall, so they were not able to initially determine exactly when or how it occurred. There does not appear to be any evidence of foul play at this point.

Detectives are investigating further and have requested the Occupational Safety and Health Administration to conduct an investigation.
