The Tennessee Bureau of Investigation has a secret weapon when it comes to sniffing out the cause of fires.

Meet Faith, the TBI's "accelerant sniffing" dog.

She is specially trained to identify certain types of chemicals, like lighter fluid, that may indicate that a fire was started on purpose.

The TBI said she has assisted in investigations across the state and has already helped solve cases since joining the bureau last December.

On Tuesday, TBI's acting director presented Faith with her official badge to wear on her harness along with a special flashing blue light.
