Remembering K-9 Deputy Diesel who just passed on September 23. Everybody is thankful for K-9 Diesel's 6 years of faithful service in the Fulton County Sheriff's Office. Hear more from Fulton County Sheriff Patrick "Pat" Labat. Diesel's been a stalwart in our K-9 unit making sure that he has apprehended or going after bad guys all the time. So for us to be able to celebrate the K-9 just as we would any other member of our department; I mean he's family.
