El Dorado County Sheriff's Office 2019 Annual Report | Page 27

Crime Scene Investigation

Crime Scene Investigators are a key piece to providing total care to the EL Dorado County Community. This team is a group of ten Deputies whose scope and training focuses on the proper preservation, collection and processing of vital evidence.

CSI is a collateral assignment, meaning everyone on the team is a full time Deputy Sheriff who are called to perform CSI duties in addition to their assignments. This team is comprised of ten individuals who are subject to be called out to a scene at any time of day, in any weather, around the clock. The team prides themselves on a meticulous work ethic as they strive to process scenes with the utmost detail, in the interest of justice.

The team regularly takes part in trainings to keep their skills sharp. Trainings include blood spatter analysis, photography and crime scene processing which, alone is a five-day course, and so much more. These trainings are conducted both in-house and by surrounding agencies and training entities. Crime Scene Investigation is a field that is constantly evolving with new science and technology and the CSI Team understands the importance of keeping up to date with these techniques and resources.

CSI responds to scenes such as homicides, suspicious deaths, robberies and other violent crimes. They often find themselves in some of the most sensitive and high profile cases in the community.

In 2019, CSI responded to 36 crime scenes. While investigating those 36 cases, the team took 99,583 photographs and collected 1,506 evidentiary items. That is an average of three call outs a month, 2,766 photographs a case, and 41 evidentiary items per investigation.

Time spent on a crime scene by the CSI Team ranged anywhere from four hours to four days. Those hours don’t include the additional time that is then spent in the CSI Lab processing and logging evidence and running additional tests to provide the best product for accurate closure of an investigation.
