A ride at the Sonoma-Marin Fair went horribly wrong Wednesday and young children and their parents were witnesses.
A worker at the fair had his leg severed below the knee on a roller coaster ride after he walked into the coasters path.
For some unknown reason, the man was on the track of the Wacky Worm ride around 2:30 p.m. The worker is an employee of the Midway of Fun, which operates the fair.
The fair had only been open for about 90 minutes when this happened. Children were on the ride at the time and saw what happened.
One witness said emergency crews wrapped the leg in ice and took it and the victim, who is said to be in his 30s, away in an ambulance.
He is now at Santa Rosa Memorial Hospital.
"Why the employee would do that, we have no idea. We are investigating it now," Midway of Fun CEO Harry Mason said in a statement.
Mason said there was no operator error or equipment malfunction. "That's why it's so baffling," Mason added. The injured man was not the operator of the ride.
The Wacky Worm was shut down for investigation, but other rides at the fair will be open through Sunday.
Wednesday was the first day of the Sonoma County fair.
The ride is a child's roller coaster that moves slowly in a figure eight pattern. Below is a YouTube video of a similar ride.
