MARR UnitThe King County Sheriff’s Office Major Accident Response and Reconstruction (MARR) Unit is responsible for responding to all fatal and critical injury collisions in our jurisdiction. The unit also investigates felony hit and run collisions and assists the Major Crimes Unit in diagramming crime scenes. Upon request the unit is available to assist other agencies with these specialized skills.

Our MARR detectives use state-of-the-art specialized equipment to reconstruct motor vehicle collisions and major crime scenes, with two- and three-dimensional computer imaging. The work requires significant on-going training and regular use of equipment and computer software to maintain proficiency. Their efforts to reconstruct collisions, photograph scenes, and analyze data are used in both criminal and tort cases (e.g., those related to road design).

The unit includes one sergeant, six investigators, and one clerk. The detectives and sergeant are available 24 hours per day, 7 days per week.
