Rodney Reed is set to be executed in Texas, despite reports that a former prison inmate claims someone else confessed to the murder that sent Reed to prison.

Reed has spent more than 21 years on death row for the 1996 murder of Stacey Stites in Bastrop, Texas. According to the police, Reed assaulted, raped, and strangled Stites.

He is scheduled to be exected on Nov. 20th but continues to maintain his innocence.

Former inmate Arthur Snow Jr. filed an affidavit in court last week saying Stites' fiancé, Jimmy Fennell, confessed to the murder years ago per CNN.

Snow was serving a sentence for forgery at a DeWitt County, Texas, prison in 2010, when he made a deal with Fennell, who was seeking protection from other inmates, the document reads.

Snow was reportedly a member of the Aryan Brotherhood gang. In his affidavit, Snow alleged that he was with Fennell in the prison yard when Fennell started boasting about killing Stites.

"Jimmy said his fiancé had been sleeping around with a black man behind his back," Snow wrote.

"Toward the end of the conversation, Jimmy said confidently, 'I had to kill my n*****- loving fiancé,'" he added. "My impression was the Jimmy felt safe, even proud, sharing this information with me because I was a member of the Aryan Brotherhood. I think Jimmy assumed that his confession would impress me and earn him credibility with the Aryan Brotherhood."

"Mr. Reed's execution is less than one month away, meaning Texas is frighteningly close to executing an innocent man," Bryce Benjet, a senior staff attorney at the Innocence Project and Reed's lead counsel, said in a statement. Between the medical and scientific evidence, and multiple new, credible witnesses, the original case trial has been completely deconstructed and disproven."
