ORLANDO, Fla.  - An acquaintance of the father of a Florida mother charged with killing her 2-year-old toddler told investigators that she was told the little girl's death was an accident.

Cecelia Benhaida said during a police interview that George Anthony told her sister the death of his granddaughter, Caylee, was an accident. She said she didn't know any other details.

The interview with Benhaida was released Friday by the State Attorney's Office in Orlando. Benhaida says her sister, Krystal Holloway, had a close friendship with George Anthony.

George Anthony's attorney didn't immediately return a phone call seeking comment.

His daughter, 24-year-old Casey Anthony, has pleaded not guilty to first-degree murder and has said a baby sitter kidnapped her daughter, Caylee.
