Mobile Crime Unit
The Mobile Crime Unit provides assistance in processing crime scenes throughout the county when requested. The unit is staffed with experienced scientists and is equipped to properly document scenes as well as properly recover and preserve any physical evidence.
The scenes encountered range from homicides to sexual assaults to burglaries. Types of evidence from these varying scenes include, for example, impressions such as tool marks and shoeprints, blood stain patterns, semen, hair, fibers, bullets, and cartridges.
The unit approaches each scene in an organized manner performing each general step: scene recognition, documentation, and evidence collection. Scene recognition includes an initial walk through with discovery of physical evidence and deciding the pertinence of it. The unit does extensive documentation of each scene by taking notes, sketching, and photographing as well as video documentation.
The most tedious and time consuming step of processing the scene is evidence collection and sometimes involves specific equipment such as alternative light sources (ALS), electrostatic lifters, and trajectory rods. Specific packaging techniques are also employed by the unit in order to properly preserve the evidence.
Proper recovery of physical evidence and documentation is crucial for an accurate reconstruction of the scene. The scientists also provide testimony, if needed, for the cases in which they processed the scene.
