Casey Anthony saga has new twist

Casey Anthony

ORLANDO, Fla. -- A Florida sheriff announced Tuesday that authorities were looking into witness tampering allegations during Casey Anthony's murder trial, even as he held a wide-ranging news conference with his top investigators in what he said was an effort to bring closure to a case that polarized the country.

Casey Anthony was acquitted a week ago on charges of killing her 2-year-old daughter Caylee in 2008. Anthony was found guilty on four charges of lying to law enforcement officers. She is to be released from jail Sunday.

Orange County Sheriff Jerry Demings held the news conference to defend his investigation and because his office had been besieged with interview requests since the verdict.

"The ultimate goal ... is that our personnel can get back to work doing the business of the taxpayers and residents of Orange County," he said. "This is the only way that we can move forward."

As for the alleged witness tampering, detective John Allen would only say the sheriff's office has interviewed some witnesses.

The investigators sat at a table alongside a large picture of Caylee. The sheriff said it was a reminder of what his investigators were pursuing during the three-year case. "This is what this was all about," Demings said. "It was about a missing child. That's what motivated our staff and our community."

Casey Anthony's mother will not face perjury charges. State attorney's office spokeswoman Danielle Tavernier said Tuesday that prosecutors have decided against charging Cindy Anthony. She initially told police she did not search for chloroform on the family computer, but at the trial she said she did.
