Just unsealed court documents from a deposition given by Casey Anthony prior to her trial show she supposedly became pregnant with her daughter Caylee at a party.

Jeff Danzinger, the psychiatrist who interviewed Anthony, noted in November 2010 Anthony told him she passed out at a party after having a beers and was given a drug.  She woke up and had her daughter 9 months later.  According to the deposition, she does not know who the father is.   Danzinger also noted Anthony was surprisingly pleasant and upbeat, considering her circumstances of being accused of killing her daughter.   He said most cases if the person believes they are being falsely accused, they would not be so happy, or able to spend time reading.   The depositions had been sealed, but the Orlando Sentinel newspaper asked they be opened, and a judge obliged.
