​Uniform Patrol

The uniformed patrol section is responsible for 24/7 emergency and nonemergency response throughout the city of Ann Arbor. Officers are deployed on three 12-hour shifts and are assigned to one of four geographical areas of the city. The patrol section is responsible for traffic enforcement as well as the enforcement of the laws of the State of Michigan and local ordinances. Patrol officers also attend community events and respond to traffic crashes and numerous other noncriminal situations. Officers assigned to patrol have varied experience and training, including traffic enforcement, criminal investigations, crime scene management, accident investigation as well as undercover and tactical operations. The patrol division also has 14 evidence technicians who are primarily responsible for collecting and preserving evidence at crime scenes. There are two officers assigned to transport prisoners to and from the jail, two K9 officers and two officers assigned to the Ann Arbor Area Transportation Authority. In total, there are over 60 officers and 11 sergeants assigned to patrol. 

Lt. Colleen McCarthy, cmccarthy@a2gov.org, and Lt. Patrick Maguire,  pmaguire@a2gov.org​, run the day-to-day operations on either the day or night shift. 

K9 Unit

The AAPD currently has two police service dogs (PSD) in service. These teams are led by Officer Jeff Shafer (K-9 Flex) and Officer Robyn Gillen (K-9 Jocko).  Their assigned specially trained canines use their keen odor-discrimination ability to assist the police department in many tasks. PSDs are used to track criminal suspects from crime scenes, search buildings and other areas for hidden suspects, locate evidence or drugs and search for lost or missing persons. They also protect their police partners and assist the department in investigating criminal activity.  AAPD canine teams work collaboratively with the teams from other agencies in Washtenaw County (WCSO, YPD, UMDPS) to support each other in meeting the often high demand for specially trained PSD teams.


The AAPD is a participating agency in the Washtenaw Metro SWAT and CNT teams.  These are collaborative teams that have been formed with other law enforcement agencies in Washtenaw County.  Members of these units have received advanced training in special weapons and tactics (SWAT) and crisis negotiations (CNT).  These teams are typically activated when there are tactical or negotiation needs that exceed the capabilities of an agency's normal resources.
