RIESEL, Texas - The body of a man reported missing in Omaha was discovered this week in a load of coal delivered by rail to Texas from Wyoming.

Workers at the Sandy Creek Energy Station in Riesel, Texas alerted authorities after they discovered the body of 25-year-old Mitchell Jackson around 10:00 a.m. Wednesday. They discovered Jackson's body while offloading coal.

Investigators say Jackson's body had fallen onto a device that filters and conveys offloaded coal.

Deputies in McLennan County, Texas used drones to search the 140-car train but found no additional evidence.

Jackson’s body was clothed and intact, and for now, the incident is being investigated as a questionable death. That could change pending the results of an autopsy.

Investigators believe Jackson had been dead for several days. The coal train left Wyoming on June 5.

Jackson had been missing since March.
