LITTLE ROCK, Iowa — A Montana man sustained what deputies called “incapacitating” injuries after his semi and trailer hauling 6,000 gallons of manure rolled and trapped him inside.

According to the Osceola County, Iowa, Sheriff’s Office, Byron J. Sharp, 54, of Whitehall, Mont. was taken by ambulance to the Osceola Regional Health Center Tuesday afternoon after being mechanically removed from his semi by the fire department.

Deputies responded to Monroe Avenue and 140th Street east of Little Rockafter 3 p.m. Tuesday, where Sharp’s 2007 Volvo Semi registered to Jarmer Manure Tanking Service of Fulda was rolled over in the ditch.

According to the report, Sharp was turning northbound onto Monroe Avenue from 140th Street and failed to make a wide enough turn, which caused the trailer to roll into the intersection’s ditch. The power unit was also pulled into the ditch and rolled completely, resting on its passenger side.

An estimated 5,000 gallons of manure spilled into the ditch.

The semi sustained approximately $30,000 in damages. The crash caused approximately $1,000 damage to the road shoulder and ditch along Monroe Avenue.

The matter is still under investigation.

The sheriff’s office was assisted at the scene by the Iowa State Patrol, ambulances and fire departments from both Sibley and Little Rock.
