Deputy in High-Profile DUI Stop Faces Investigation

A.J. Ross has a spotty disciplinary history

A Rutherford County Sheriff's deputy at the center of a controversy tied to a videotaped DUI checkpoint stop has in the past drawn the scrutiny of his superiors and once resigned from the office, a review of disciplinary records shows.

Deputy A.J. Ross was featured in a July 4 video posted by the Libertarian Party that depicted a verbal altercation between Ross and 21-year-old Chris Kalbaugh. The Middle Tennessee State University junior accuses Ross of violating his constitutional rights during a checkpoint stop.

Sheriff Robert Arnold's office has refused to comment on the video, other than to say Ross's actions are "currently under investigation."
