Mahnomen County Sheriff Doug Krier reported Friday morning that at 2:18 p.m. Thursday, July 8, his office received a 911 cell phone call from a road construction site in northeast Mahnomen County.
The caller reported that Timothy Henneman, 28, of Ashby, Minn., was trapped in a trench about 12 feet below road level, and workers on the scene were trying to free him.
When deputies and paramedics arrived, Henneman had been released from the soil, which had partially buried him. He suffered serious leg injuries. Workers on the scene said Henneman was trapped when a 4-foot-diameter clay ball rolled back into the trench striking and pinning him.
Henneman is an employee of Minnerath Construction of Cold Spring, Minn., the company conducting the road project for Mahnomen County.
Henneman was stabilized at the accident site and airlifted to MeritCare-Sanford Health in Fargo, N.D., by Lifeflight. Henneman's condition was unavailable Friday, but the sheriff's office reported that his injuries were believed to be non-life threatening.
Responders to the accident were Mahnomen County Sheriff's Office, White Earth Ambulance Serivice, Lengby Rescue, First Care Ambulance of Fosston, White Earth Department of Natural Resources and Lifeflight.
