The Criminal Investigations Division, commanded by Captain Dale Long, is tasked with investigating reports of criminal acts, as well as taking proactive measures to prevent crimes from occurring. Investigators are responsible for case development activities, including locating and recovering stolen property, gathering and processing forensic evidence from crime scenes, and interrogating criminal suspects. Investigators then compile and organize this information before presenting it to the courts for prosecution.
The Hall County Sheriff's Office has developed partnerships with local and federal agencies to provide a unified response to certain illegal activities. Currently there are investigators assigned to an FBI task force to combat gang activity and to a Drug Enforcement Administration task force to focus on drug related crimes.
