Security video first uncovered by NewsChannel 5 Investigates has now become evidence in the TBI's investigation of Mayor Megan Barry.
Agents obtained the video Friday after seeing NewsChannel 5's story.
That video shows the mayor's SUV repeatedly driving into the Nashville City Cemetery in the early morning hours.
She was driven there by the police bodyguard with whom she was having an affair.
After NewsChannel 5's report on Thursday, TBI agents showed up Friday at the business where the cameras were located to add to their investigation of Barry.
