Zack is one of the hardest-working canines in the Squad. Detective Ryan and Zack were certified as a narcotics detection team approximately two years ago. In December 1989, the Narcotic Division K-9 Squad was formed and Officer Parham was selected as one of the original handlers. In March of 1997, Officer Parham was promoted to the position of head trainer for the K-9 Squad. The Los Angeles Police Department purchased Arrow in June 1995.
Arrow is one of the largest and friendliest canines in the squad.
Officer Parham and Arrow were certified as a narcotics detection team at the beginning of this year. Officer Graciano is a 13-year veteran with the Los Angeles Police Department. He has worked a variety of assignments including patrol and narcotics enforcement. In June 1994, he was selected to the K-9 Squad. Due to his expertise and ability to speak Spanish, Officer Graciano was chosen to travel the country of Paraguay to train their narcotic canine handlers and canines at the request of the Paraguay government.
