Cooke County Sheriff’s Office
Criminal Investigations Division


The Criminal Investigation Division, commonly known as CID, provides professional investigative services to the unincorporated areas of Cooke County, and cities in Cooke County by request. CID is responsible for the supervision of all Cooke County Sheriff’s Office investigations of serious crimes. CID Sergeant Investigators primarily investigate felony-level crimes and provide criminal investigative support to the Patrol Division. CID conducts a broad spectrum of criminal investigations to include deaths, sexual assaults, offenses against children, arson, armed robbery, burglaries, fraud, computer crimes and identity theft. CID searches out the full facts of a situation, organizes the facts into a logical summary of investigative data, and presents this data to the District Attorney’s or County Attorney’s Office. CID coordinates with Abigail’s Arms, Child Protective Services and other groups and agencies to help fight child physical, emotional and sexual abuse. CID works closely with other local, state and federal law enforcement agencies to counter and investigate the most serious crimes.
