Unit Description

The successful prosecution of criminal cases requires a thorough and professional police investigation which frequently integrates the skills of personnel trained in evidence detection, preservation, collection, and analysis. This process, very often, begins at the crime scene. The Crime Scene Unit was established for the purpose of providing specialized and technical services to the entire Middlesex County law enforcement community. While the majority of responses are to homicide and suspicious death scenes, the Unit is regularly called upon to assist municipal law enforcement with the detection, preservation, collection, and analysis of evidence in a variety of criminal cases.
The MCPO entered into a partnership with the Somerset County Prosecutor’s Office Ballistic Laboratory.  An MCPO Detective is assigned to the lab to perform as a Firearms Examiner as part of a shared services agreement to fund and utilize the Brass Tracker 3 component of the Integrated Ballistics Identification System (IBIS). IBIS facilitates information sharing through the National Integrated Ballistic Information Network (NIBIN) as it relates to ballistics evidence.
The MCPO also enjoys a partnership with the Union County DNA Laboratory whereby an MCPO DNA Analyst is assigned to the lab.  As a result of this endeavor, DNA evidence related to major crimes in Middlesex County is now being processed in a more timely fashion, increasing the likelihood of a successful resolution to investigations and subsequent prosecutions.
