Sheriff's detectives work closely with patrol deputies, other law enforcement agencies, and Ada County citizens to investigate crimes such as theft, fraud, burglary, sexual assaults, robbery and murder. The success of an investigation relies heavily on the detailed collection of physical evidence and on intelligence gathering.

In this high-tech age, computer crimes such as "hacking," counterfeiting, identity theft, creating false identification, Internet fraud and child pornography have created a new challenge to law enforcement. The Sheriff's Office has provided focused resources in this area to better understand the technical complexities and solve Internet crime.
