A branch of the Homicide Unit, the Serious Collision Response Team is responsible for all criminal cases that involve motor vehicle crashes. SCRT is notified of all serious and fatal motor vehicle crashes in Mercer County and an on-call detective responds to the scene when needed. Duties at the scene include scene measurements, photographs and interviews. The unit also provides scale scene diagrams. In addition, SCRT detectives are trained in crash reconstruction and can provide speed estimates and full reconstructions of crashes.
