LOUISVILLE, Ill. (AP) — A central Illinois sheriff’s department has started a K-9 unit for the first time in 20 years due to fears of a heroin epidemic. The Effingham Daily News reports the Clay County Sheriff’s Department recently launched the unit after Deputy Cory Heuerman and a 2-year-old Malinois named Fallax received certifications. The department says the dog is the “office’s proactive response to the fear of a heroin epidemic.”
