When Should I Call the Non-Emergency Line?

The Investigations Bureau falls under the direction of a Deputy Chief and is divided into two distinct categories. With oversight from a division Captain, members of the Forensics Unit, Property Crimes and Violent Crimes details work to investigate criminal cases. A second division Captain oversees the Organized Crime Unit, Special Crimes Unit and the Internet Crimes Against Children Task Force.

Crime Scene investigators work cooperatively with the Field Operations officers and investigators in collecting evidence at crime scenes. Depending on the evidence, they work with the ID unit and fingerprint examiners to make positive identifications. When guns and ammunition are used in a crime, forensic examinations are conducted by ballistic experts who have received specialized training.
Property Crimes detectives make up specialty teams investigating Burglary & Larceny, Auto Theft, Forgery and Fraud cases. The Pawn Shop detail works to support theft investigations while Polygraph Examiners are committed to confirming the truth. The responsibility of handling criminal summons’ and Sex Offender Registry falls under the Violent Crimes Unit. 
The Organized Crime Unit is comprised of investigators who are assigned to narcotics, intelligence, gangs, and the Drug Related Death Task Force. Additional teams under the Special Crimes Unit include those who investigate domestic violence, elder abuse, human trafficking, juvenile crimes and missing persons. While officers from these units focus on crimes relating to their assignments, investigations oftentimes bring them together to pool their areas of expertise.

The Internet Crimes Against Children (ICAC) Task Force consists of investigators and electronic evidence forensic examiners. The Knoxville Police Department is the lead agency for the Tennessee ICAC Task Force and assists law enforcement agencies from across central and east Tennessee in investigating child exploitation.
