Tewksburyâs Police Department just added a new officer, though unlike most of the other ones this one walks on four legs (and barks). Thanks to a grant from the Stanton Foundation, Tewksbury received the funding to add a second K-9 to its police ranks. Logan will now join K-9 Leo on the force after recently completing a 14-week basic training program at the Boston Police Academy along with his new handler, officer Stephen Quinn. It was officer Quinn who came to new Police Chief Ryan Columbus with the idea to add a second K-9. The officer said he always wanted to do it, even though he admitted to having little experience with a working dog (though he did say he has experience with dogs in general).
