A retired Putnam County Sheriff's K9 has passed away. 10-year old Duncan retired from Putnam County Sheriff’s Office in 2016 after 8 years of service. K9 Duncan was a certified patrol, tracking and narcotics dog, credited with over 300 narcotics arrests and solving over two dozen property related crimes. Among her numerous tracks to locate missing persons, was finding a two-year old in the wooded Roaring Brook area of Putnam Valley. She heard the faint cry of a child who was then found behind a tree-- safe but scared. K9 Duncan's End of Watch was yesterday.
