New information has surfaced that a law-enforcement program under investigation by the state was run by a Minnesota state trooper who’s faced multiple internal complaints about his behavior on the job. The Department of Public Safety is investigating the state’s Drug Recognition Evaluator program after allegations that officers gave people illegal drugs. A new reports released Friday says that prior to leading the program, Sergeant Rick Munoz was the subject of 9 internal complaints about his conduct during eight years with the state police, and was found in violation in 6 of them. The program in question aims to teach officers to spot if someone is using drugs, but has led to allegations of officers giving drugs to people. A Hutchinson police officer is among those facing possible charges. The State Patrol has not commented on the allegations against Munoz or the drug recognition program.
