Administrative Investigation Division

Office: 213-473-4340

Administrative Investigation Division is commanded by Captain III David Grimes and is responsible for investigating complaints of misconduct that are primarily administrative in nature. Investigators assigned to AID collect and preserve evidence, interview complainants and witnesses, and ensure other investigative approaches are conducted or considered such as photographs, drawings, and records research. The accused employee is interviewed, and a report is assembled and submitted to the AID Commanding Officer. The final report is sent up the chain of command, and ultimately arrives at the Chief of Police, who has the final word on discipline within the Police Department.

Administrative Investigation Division is comprised of four investigative sections, each led by a Officer in Charge (Lieutenant II) and an Assistant Officer in Charge (Detective III), with several investigators (Sergeants II and Detectives II):
