The footage appears to have been filmed on a camera inside the police car on the night of February 18, 2002.
That night Michael David Carruth and Jimmy Lee Brooks had called in at the Bowyer house pretending to be narcotics officers.
Bowyer was reportedly targeted because of the large amounts of cash he kept in the house.
The pair told Bowyer he was under arrest for drug possession and loaded him in the car. The men then handcuffed Brett and put him in the car.
They took Bowyer's money, drove him out of the city and slit his throat. They threw him into a shallow grave where he pretended to be dead.
His son was then shot and thrown on top of him.
Bowyers dug his way out of the grave and crawled onto the highway where police found him.
Due to the evidence and testimony from Bowyer, Carruth and Brooks were arrested. They were also accused of killing a couple three weeks earlier.
Carruth was found guilty of the killings and sentenced to death. Brooks admitted the crimes and was also sentenced to die.
The men are still on death row in Alabama.
