ST. CLOUD (WJON News) -- A St. Joseph man has pleaded guilty to driving a jet ski while under the influence of alcohol and seriously hurting two boys on a tube he was pulling.

The incident happened in July when 43-year-old Ryan Willis was pulling the boys on a tube and they hit a dock on Watab Lake.

According to the charges, one of the boys was airlifted to Children's Hospital with an apparent skull fracture, a large cut on his head, and a bruised lung. Records show the other boy had concussion symptoms and body pain. He was brought to St. Cloud Hospital for treatment.
