UPDATE: Neal Pinkston, Executive Assistant District Attorney, confirms District Attorney Bill Cox was briefed Wednesday morning on an investigation involving the Chattanooga Police property division.

Following the briefing, General Cox contacted the Tennessee Bureau of Investigation to request assistance with the investigation.

A Chattanooga police officer is on administrative leave and multiple sources within the department tell Channel 3 Eyewitness News that drugs and guns are missing from the evidence property room.

Channel 3 can confirm that the officer is Chattanooga Police Sgt. Kevin Kincer.

Channel 3 has also learned that internal affairs detectives are doing inventory to determine the extent of the missing evidence.

So far, sources say, a "significant" amount of drugs is unaccounted for, including drugs seized during arrests and those collected from prescription pill drop-off containers. The officer placed on administrative leave is a property crimes investigator.

Mayor Andy Berke's spokesperson, Lacie Stone, referred questions to the CPD's spokesperson. Sgt Wayne Jefferson, the department's Public Information Officer, told Channel 3 he is unaware of any ongoing investigation and would only be informed of such an investigation once it is complete.
