ORLANDO, Fla. (AP) -- A South Carolina inmate has filed a petition against Casey Anthony seeking a DNA test to determine if he was the father of her 2-year-old toddler.
Christopher Umberger filed the petition in Orlando against Anthony, who was acquitted earlier this month of killing her daughter, Caylee.
Prison officials say Umberger was behind bars when she was conceived.
Umberger made the claim in court documents this week, but federal prisons spokesman Chris Burke says he was in prison between 2001 and 2009 for heroin trafficking. Umberger violated his supervised release and is in a South Carolina prison.
Caylee was born in August 2005. It's not clear who Caylee's father is or how she died. Her mother, Casey Anthony, was acquitted of killing Caylee last week.
Meanwhile, a hearing to determine if Anthony can be deposed for a defamation lawsuit before she leaves jail Sunday ended when the judge recused himself. Zenaida Gonzalez says her reputation was damaged when Anthony claimed a baby sitter with her name kidnapped Caylee.
Anthony is set to be released from jail on Sunday.
Umberger says in the court filing that he intends to sue Anthony for Caylee's death. He provided no details to back up his claim.
The hearing adjourned after only a few minutes when Judge Jose Rodriguez said he was recusing himself. He didn't explain why.
