A Florida man's ex-wife used a stun gun on him, tied him to a truck bumper and dragged him for half a mile before he escaped, the Volusia County Sheriff's Office reported.

Robert Hall, 54, is being treated in the surgical intensive care unit of Halifax Health Medical Center in Daytona Beach. He suffered broken pelvis, broken facial bones and bleeding in his brain, according to the sheriff's office.

His ex-wife, Jeanette Morris, 61, is under arrest.

The attack took place in a rural part of New Smyrna Beach where Hall stayed at the home of his ex-wife while she was away working as a truck driver.

Morris suspected that Hall had allowed his girlfriend in the house and arranged for a deputy to escort her when she returned to her home in order to avoid a confrontation, the sheriff's report said. The deputy left the house after Morris told him she would spend the night at her brother's house.

Instead, Morris and her brother, Harold Anderson, 63, and a woman named Joan Hobart, 46, began drinking vodka with Hall. The three then turned on him, shocked him three times with a stun gun, punched him in the face and put a gun to his head.

They tied Hall's hands behind his back then tied his ankles together and attached the rope to the bumper of the pickup truck and dragged him for half a mile. After the truck stopped, the three tossed Hall into the truck bed, cut off some of his hair and talked about scalping him and looking for a hole to bury him.

As the truck was driven off again, Hall leaped out and ran to a house for help.

Morris, Anderson and Hobart are each charged with attempted murder, conspiracy to commit murder, false imprisonment, aggravated battery and aggravated assault.
