K-9 Unit

K-9 Structure

The K-9 Unit is part of the Field Services Division. Deputy Jackson Bradley with partner Thor, Deputy Shane Roelofs with partner Jocko and Deputy Kyler Rosin with partner Kalo are currently assigned as K-9 officers.  Our K-9 units are on call 24 hours a day, 7 days a week, 365 days a year to serve the needs of the citizens and visitors of Grand Traverse County.  
 

Function of K-9 Units

With over 400 calls for service a year, the Grand Traverse County Sheriff's Office K-9 units are one of the busiest in the State. All three dogs are trained to track and apprehend criminal suspects, locate lost or missing persons, conduct building searches, and can locate stolen property or articles discarded by criminal suspects. Along with these functions each is also trained as a detection dog. Our explosive detection dog, Thor, is used to search for explosives in a wide variety of circumstances. Narcotics detection is assigned to K-9s Cade and Kalo.  They can search for illegal drugs on traffic stops, drug raids, prison searches, and any other place where drugs can be hidden.  Our dogs have had hundreds of hours of continuing in-service training.

History of K-9 Program

The Grand Traverse County Sheriff's office Canine Unit has had a long and distinguished history that dates back to the 1960's when Sergeant Roy Strait and his partner "Luger" became the first to serve the department. After a very successful career, the department realized what an asset a good K-9 team could be to the department. Since the first team went into service, the Sheriff's Office has had many great dogs with 3 currently in service.

Current Handlers

The current handlers are Deputy Jackson Bradley, Deputy Shane Roelofs and Deputy Kyler Rosin, all are working to provide a continuum of excellence that has been a standard in Grand Traverse County since the beginning of the K-9 program.
