Columbia County Detectives

The Columbia County Sheriff's Office currently has five detective sergeants and a detective lieutenant on staff. The primary mission of the Detective Bureau is to investigate criminal activity in and around Columbia County.

The Sheriff's Detective Sergeants are Deputies that have been promoted to the position. The Detectives are called upon to investigate crime scenes, which include all categories of crimes including but not limited to homicides, sexual assaults, battery and abuse, juvenile, and other crimes against persons as well as robbery, burglary, theft, drug violations and other property crimes.  Sheriff's Deputies typically begin the investigation and often complete the investigation without calling a detective. However when the investigation will be time consuming and require additional evidence collection and interview techniques a detective is needed.
