The national spotlight has been turned on a horse trainer in Collierville facing federal charges of abuse.
Four people are charged with violation of the federal Horse Protection Act.
The Humane Society of the United States released video today of Tennessee Walking Horses being abused.
The video was taken in 2011 at Whitter Stables in Collierville owned by prominent trainer Jackie McConnell.
It shows horses at his stabled undergoing soring.
According to the Humane Society, soring is a banned practice of using chemicals and chains to train the horses to perform a high-stepping gait for shows and competitions.
Basically, a chemical is put on the horses ankle which creates pain and an open sore.
Chains are then places on the open sore so when the horse is galloping, the chains cause pain which causes the horse to raise its leg up creating the signature Walking Horse gate.
McConnell has agreed to plead guilty to one count of conspiracy to violate the Horse Protection Act, according to court records.
The above video is part of a Nightline report aired Wednesday night.
