CHATTANOOGA, Tennessee - February 3, 2010 - A sheriff in rural Tennessee has been accused of threatening a husband and wife by "blowing their heads off" and "inappropriately" touching the wife during an unwarranted traffic stop.

In a lawsuit filed in a federal court in Chattanooga, Shawn and Michelle Graham allege that a group of police deputies, wearing camouflage and not identifying themselves as law enforcement officers, stopped the Grahams' car in January 2009, pushed a gun through the window of the Grahams' Nissan and pointed it at the husband, "sometimes tapping his head with the barrel."

The officers ordered the couple out of the car, and frisked them while yelling "death threats and angry curses at the Grahams."

The Grahams say Sheriff Ronnie Hitchock of the Sequatchie County Sheriff Department personally carried out a pat down of Michelle Graham, during which he "reached inside the pockets of her clothing, making inappropriate contact with her breasts and groin areas. Handcuffed in the back of Sheriff Hitchcock's cruiser, Mr. Graham was forced to watch this unconstitutional spectacle."

The lawsuit states that even though the officers' search turned up "no weapons, no drugs and no contraband," the couple were taken to a police station and strip-searched. The Grahams were never charged with any crime.
