Lansing Police Department Crime Scene Investigations Unit

CSIVanThe Lansing Police Department’s Crime Scene Investigations (CSI) Unit has been developed to work in conjunction with the Criminal Investigations Division (CID) on all major investigations within the Village of Lansing, Illinois. The proper collection of evidence assists CID in the successful identification and prosecution of criminal offenders.

The CSI Unit primarily responds to death investigations, armed robberies, major burglaries, fatal vehicle crashes, crimes against persons, or other types of investigations that may benefit from the collection and preservation of evidence from the crime scene.

The LPD CSI Unit currently has seven specially trained officers available 24 hours a day to respond to and investigate crime scenes. Those officers have all gone through a 40 hour crime scene investigations course, in which they are trained in digital forensic photography; evidence identification, processing, collection, and preservation; and scene diagramming and documentation. Many of the officers in the unit have also had advanced training in latent print recovery, chemical processing, accident scene investigations, blood stain/spatter analysis, forensic computer analysis, and death investigations.

When LPD CSI personnel are dispatched to a scene, they respond in the Special Response Unit (SRU), a custom converted ambulance, which is outfitted with specialized gear to process any type of crime scene. The SRU is equipped with a wide variety of equipment including a portable generator, high intensity lights, ladders, and an assortment of tools to assist investigators. Other high tech equipment such as an electrostatic dust print lifter, forensic alternate light sources, impression casting materials and an array of various fingerprint powders are also readily available in the SRU. The SRU can also be utilized as a mobile command center should the need arise.

One of the most important aspects of evidence collection and preservation is protecting the crime scene. This is to keep the pertinent evidence uncontaminated until it can be recorded and collected. The successful prosecution of a case can hinge on the state of the physical evidence at the time it is collected. The protection of the scene begins before arrival of the first police officer at the scene and ends when the scene is released from police custody. If you are the victim of a crime, it is just as important for you to help protect the crime scene as it is for the police officers when they arrive. You can assist by disturbing as little as possible and taking careful note of what you changed in the scene from the way it was when you discovered it. Don’t be surprised when a Crime Scene Investigator asks to take your fingerprints too, this is to help eliminate any fingerprints you may have left on an object and lets the investigators focus on those prints that aren’t yours. These are called “elimination prints” and are invaluable to investigators.
