The Lake Ozark Police Department reported this morning that Mark Johnson, 55, originally from Colorado, died Sept. 29, as the result of the stab wounds and head trauma.

John J. Powell, 39, was originally charged by the Miller County Prosecutor with three counts of assault in the first degree (Class A felonies) and three counts of armed criminal action. Powell also had a warrant from probation and parole.

Additional charges against him are anticipated in the wake of the victim's death.

At approximately 1:35 a.m. on Friday, Sept. 22, the Lake Ozark Police Department received a call of an unconscious man at the campgrounds below the dam who had possibly been assaulted and dragged behind a car.

Officers arrived on scene and found the unconscious male near the bathhouse at the campground. CPR was initiated and the subject was transported by Lake Ozark Fire Department ambulance to Lake Regional and then transferred to University of Missouri Hospital in Columbia with life threatening injuries.

Investigation at the scene indicates that two male subjects staying at the campground had gotten into a physical altercation. Powell was standing over the victim and covered in blood as officers arrived. Powell made an admission to officers on scene that he had assaulted the victim.

Initial investigation indicates that the victim was physically beaten, stabbed several times in the head, arms and hands and was then dragged behind a vehicle through the campground for several hundred feet.

Powell and his wife had been tent camping at the campground for at least two weeks and the victim had just met them that day while also staying at the campground.
