A 25-year-old La Crosse man is going to prison for 10 years for hitting a police investigator with his car.  The incident happened last year in Holmen.  Brandon Ritter entered guilty pleas to charges of manufacturing and delivering meth, and second-degree recklessly endangering safety.  Police Investigator James Mancuso suffered minor injuries in the incident.  He fired four shots into Ritter’s car shortly before the impact.
