The Investigative and Analytical Department (ACS) is headed by Colonel Andrei Gromov. Employees of the department are engaged in the search for criminals and forensic examination. They study evidence, build an evidence base, interview witnesses, and conduct face-to-face interviews in a high-tech office equipped with the latest technology. Agents can find at the crime scene not only fingerprints, but also traces of electronic devices that were in the area at the time of the murder. In this, the ACS staff is assisted by a mobile "Scanner" laboratory with access to cell towers.
