Investigations
The Investigations Unit is part of the Operations Division of the Sheriff's Office. The unit consists of twenty-three full-time detectives, a crime analyst, two sergeants, and one lieutenant. The Investigations Unit puts in the long hours investigating the most complex crimes, keeping the patrol deputies available to respond to calls for service.
Investigators specialize in a variety of assignments, including Property Crimes, Elder Abuse, Financial Crimes, Hi-Tech Crimes, Sexual Assault, Persons Crimes, Homicide, Narcotics, and Cold Case Crimes.
These investigations typically involve felony-level crimes that may require a substantial time and resources to resolve. It is the highest priority of the Sheriff's Office Investigations Unit to discover all evidence and bring closure to cases in support of the Sheriff's Office vision of total care, total enforcement, and total professionalism.
When a large-scale, complex investigation or critical incident occurs, detectives collaborate as a full unit to investigate these events. To better serve the community and victims of crimes, the Investigations Unit collaborates with other law enforcement entities throughout the county, region, and state. The Investigations Unit has many partnerships with government and community-based organizations.
The Investigations Unit is located at 200 Industrial Drive, Placerville, CA 95667. If you have questions regarding an ongoing case or if you have information pertaining to an active case, please call (530) 642-4703.
Crime Scene Investigation (CSI)
The Crime Scene Investigation (CSI) Unit comprises eleven Deputy Sheriffs and is a collateral assignment within the Operations Division. CSI works directly with detectives in investigating major crime scenes such as homicides, any deaths with suspicious circumstances, officer-involved shootings, armed robberies, large-scale burglaries, and more.
The CSI Unit is responsible for searching crime scenes for evidence and preserving them through thorough examination, documentation, and evidence collection. The scene is documented using various methods, including detailed reports, video, photography, DNA collection, UAS overhead video, and laser diagramming equipment and software.
The CSI Unit also analyzes evidence collected by patrol deputies from burglaries, assaults, and stolen vehicles. This evidence is often processed for fingerprints and DNA evidence. Criminal evidence processing is performed in the CSI lab. The CSI Unit responds to callouts 24 hours a day and are prepared to process any scene.
