Jail Call: Missing Girl's Grandma, Mother Argue

The mother of a missing 2-year-old Orlando girl told family that she didn't know the whereabouts of her child in a contentious telephone call from jail released Friday.

A new report released today revealed that authorities discovered a heart shape sticker and children's clothes near the body of Caylee Anthony, who was found dead in December 2008.

Casey Anthony, 22, is being held on $500,000 bond after investigators said she lied to them and did not report daughter Caylee Marie Anthony missing for more than a month.

In the July 16 call released by the Orange County Corrections Department, Caylee's grandmother, Cindy Anthony, complained to her daughter that she wasn't telling her where the toddler was. Casey Anthony responded angrily that she didn't know where the girl was.

"Are you kidding me?" Casey Anthony said.

Cindy Anthony responded, "Don't waste your call to scream and holler at me."

She added that her daughter's incarceration is her own fault.

"You're blaming me that you're sitting in the jail? Blame yourself for telling lies," Cindy Anthony said.

Missing Florida Toddler Spotted?

Prosecutors said in court earlier this week that Casey Anthony is a person of interest in what is beginning to look like a homicide investigation, though she has not been charged. Sheriff's deputies testified that her car smelled of decomposition and a cadaver-trained dog noted a smell of human remains there.

Casey Anthony has been charged with child neglect, making false official statements and obstructing a criminal investigation.

In the same call, Casey Anthony said calling her family was a waste of time and told an unidentified female the family isn't supporting her.

"Nobody in my own family is on my side ... They just want Caylee back. That's all they're worried about right now is getting Caylee back and you know what, that's all I care about right now," she said.

A telephone message left after business hours at the office of Casey Anthony's attorney, Jose Baez, wasn't immediately returned.

Cindy Anthony called 911 on July 15. In one call, she asked police to arrest Casey Anthony for stealing a car and money.
