By Paul DentonAbandoned in the 1980s, Rick Singer was found dead in his cell in a maximum-security prison in Alabama in February 1980.

The coroner’s report stated that Singer died of asphyxiation.

The cause of death was ruled as “natural causes,” but Singer’s lawyers say he was beaten and tortured by corrections officers.

Singer’s parents, Bob and Nancy Singer, are still fighting for justice for their son, who was born into slavery.

Bob Singer told CNN that his son was tortured by his guards.

“They beat him so badly he could barely breathe, and he was in a cell that was so small and so cold that he was barely breathing,” Bob Singer said.

“He was locked up for 24 hours a day for 24 days straight.”

Nancy Singer told the Washington Post that her son was beaten for weeks at a time.

“The first day I met him, he had bruises on his face and body and he said that he felt like he was dying,” she said.

“Rick was in there for three days straight, but he was never able to breathe for two of those days.”

After his release, Rick was placed in a juvenile facility for his own protection, where he spent a year and a half.

The singer died of natural causes in prison in 1987, but his parents say they are still trying to uncover the truth.

“When I think of the truth, I don’t want to believe it, but when I think about the fact that we lost him, I just feel that it’s the right thing to do,” Bob said.
