The BIPD’s investigations unit is comprised of a detective sergeant and two detectives that investigate major crimes occurring in the community and perform follow-up investigations on cases initially handled by patrol officers with regard to property crimes and crimes against persons. Detectives interview suspects and victims, take witness statements, collect and process crime scene evidence, and testify in court. Additionally, detectives conduct background investigations of agency applicants, represent the department at local meetings and committees, and fill in for patrol during shift shortages.
