Moby has been used and has been able to detect illegal narcotics secretly hidden within vehicles and houses.
Officer Mansfield and Moby often can be found at many island events conducting demonstrations to show how they work. Recently, they have been at The Island Fair, Star Program, Nantucket New School and have marched in the Memorial Day parade.
