Travis Parker, 13, was pinned to the ground by up to three staffers on April 20 after he protested when he was denied food as punishment, according to documents from the Human Resources Department.

The state human resources agency has fired an official responsible for training at the therapeutic wilderness camp where a 13-year-old boy was restrained for over an hour and died.

Sam Shoemaker, a 17-year veteran of the camp who rose from a counselor to camp director to his job overseeing training, was fired Aug. 18 after he refused to take a lie-detector test regarding the practices at the camp, officials said.

The Appalachian Wilderness Camp in North Georgia, has come under scrutiny following the April death of Travis Parker, who died after being restrained in a prone position for 1 1/2 hours. An autopsy determined the face-down restraint caused his death, and six camp counselors, ranging in age from 25 to 36, have been charged with murder in his death.

Shoemaker was in charge of ensuring training was consistent between the Appalachian camp and the other state-run camp for troubled youth in Warm Springs. Shoemaker was directed to take the lie-detector test as part of an internal investigation into the incident by the state Division of Mental Health, Developmental Disabilities and Addictive Diseases.

"He was terminated for his failure to cooperate with the investigation," said agency director Gwen Skinner.

Shoemaker could not be reached for comment.

Officials said they were hoping to resolve conflicting accounts of the practices at the camp. While Skinner has said that prone restraints were prohibited on campers, the counselors have said they were acting as they had been trained.

Shoemaker, according to the agency's investigative report dated May 27, had told investigators that the face down restraint had been used for at least 17 years.
