In a video of a jailhouse visit played for jurors Friday, Casey Anthony grows noticeably exasperated as her parents press for answers about her missing daughter.
Near the beginning of the video, her mother Cindy Anthony suggests the possibility that her granddaughter Caylee
had died accidentally.
"They are saying Caylee drowned in the pool,"
"Surprise, surprise," Casey, 25, responds dismissively.
Two jurors in the Orlando courtroom took notes when they heard the exchange. The defense has claimed
that Caylee, 2, drowned accidentally
on June 16, 2008.
This jailhouse visit occurred nearly two months later, on Aug. 14.
As the visit continues, Casey Anthony bristles as Cindy asks her for information.
"I'm frustrated and I'm angry," Casey says. "This is the first time that I've truly, truly been angry this entire time, but I'm so beyond frustrated with all of this."
Anthony also snaps at her mom and father George for interrupting her.
"Nobody's letting me speak," she complains angrily. "Give me three seconds to say something. ... My entire life has been taken from me. Everything has been taken from me."
