Source: Dead Prison Inmate Was Castrated

BUCKEYE, Ariz. -- CBS 5 News has learned that an Arizona prison inmate who was found dead on Friday was castrated by his cell mate.

Shannon Palmer died from his injuries Friday at Lewis Prison in Buckeye, according to prison officials, who would neither confirm nor deny that he was castrated.

His cell mate, convicted murderer Jasper Rushing, is believed to have castrated Palmer, someone with knowledge of the incident told CBS 5 News.

Palmer was serving a three-year sentence for criminal damage out of Maricopa County. It was the fourth time Palmer was in prison, according to a Department of Corrections spokesman. The spokesman said that an investigation is ongoing

Inmate Claims He Knows Who Killed Caylee Anthony

WFTV.COM- A Florida prison inmate wrote a letter concerning the Casey Anthony case in July 2009 and Eyewitness News obtained a copy Monday (read it).

Jerry Jackson is a 21-year-old inmate (see mug) behind bars since 2004 on a 30-year sentence for crimes committed in 2002, including sexual battery with a weapon, armed burglary and kidnapping.

The letter, written on July 22, 2009 and addressed to "whom ever is representing Ms. Anthony," suggests that Jackson knows who killed Caylee Anthony and claims it was not Casey. The letter was mailed to the Clerk of Courts and added the Casey file.

"I happen to know for a fact who killed her in which who is not Casey Anthony," Jackson wrote in the letter. "The person that killed her was a guy whose name I will not reveal at this time."

Jackson wrote, if no one responded by August 15, he'd take the information to his grave. Jackson has received mental health treatment and has told Eyewitness News in the past he's committed unsolved crimes that police say is not true.

Jail officials said Jackson never told anyone at Union Correctional Prison in Raiford, Fla. that he had the information and neither law enforcement involved in case nor Casey's defense has visited him.

In April 2006, a then 18-year-old Jackson claimed in a letter written from behind bars that he kidnapped missing 13-year-old Ashani Creighton and killed her. However, his claims were dismissed amid a history of mental illness.
