CCSO Sgt. Doherty and K-9 Rino (CCSO photo) The Charlotte County Sheriff’s Office on Monday announced that one of its K-9s has died. K-9 Rino was diagnosed with bone cancer and retired April 28 after four and a half years with the agency. “His love for his work was evident in his successful apprehensions, removal of illegal narcotics off the street, and most importantly, keeping his partner Sergeant Doherty, safe. His work ethic was unmatched, and his connection with his partner is irreplaceable,” CCSO said in a Facebook post. “His fight ended peacefully June 19th with his partner by his side. We’ll take it from here.” Rino was recently included in a collectible set of K-9 trading cards being handed out by CCSO deputies. The K-9 made headlines in August 2018 when he tracked a fleeing suspect into heavy brush in Punta Gorda.
