The Cyber Crime Unit operates within the Criminal Investigation Division. The unit assists all officers in the department and other law enforcement agencies in the investigation of any crime involving digital evidence (computers, cell phones, secure digital cards, thumb drives, or any other device that stores data.) In cases where digital evidence is a factor, cell phone records and records from electronic service providers enhance investigations and preserves the integrity of seized digital evidence. The unit investigates complex cases and provides assistance to officers and detectives with drafting search warrants that give legal authority to search for digital evidence. This unit provides assistance with gathering evidence from cell phone companies and online service providers. This technology provides detectives with the technology to complete their tasks and to provide assistance with obtaining video from video surveillance systems in businesses, homes, and vehicles. The unit is part of the United States Secret Service Cyber Fraud Task Force and Internet Crimes Against Children Task Force.



The investigation of crime and the prosecution of offenders requires that information be obtained through the application of scientific knowledge and methods. In order to effectively use laboratory support services, physical evidence must be identified, collected, preserved properly and transmitted to the laboratory. Physical evidence is of major importance in all cases, particularly in those cases that have no witnesses. The successful prosecution of a case often depends on the quality of the physical evidence that is collected and the manner in which it is presented.

Our evidence building allows us more space on the forensic side for processing of items for latent evidence through different chemical processes, i.e. Cyanoacrylate Fuming (Super Glue). A new lab offers a vented hood for the chemical processes like Ninhydrin. A Cyanoacrylate Fuming Chamber allows us to fume without breathing hazardous fumes, and a bullet trap allows us to fire rounds safely to collect shell casings to be sent to the ATF for entry into NIBIN (National Integrated Ballistic Information Network). The lab is also used for the weighing of controlled substances, macro photography used in latent processing, and a down flow hood used to dust items for prints.
