Prosecutors say Anthony used chloroform on her daughter and then put duct tape on her nose and mouth to suffocate her. The Orlando woman's attorneys say Caylee drowned in the family pool on June 16, 2008. They say Anthony and her father panicked and covered up the death.  George Anthony denied the claim during his testimony last week.  The videotaped exchange, during which Anthony became agitated with her parents as they pressed her for details of Caylee's whereabouts, was one in a series shown to jurors the past two days.  "We need to have something to go on," Cindy Anthony pleaded during the visit.  "Mom, I'm sorry. I don't have anything," Casey Anthony angrily replied. 'I've been here a month. Do you understand how I feel?"  In the videos shown to jurors on Friday, Anthony repeatedly expresses frustration at being jailed and her inability to offer additional help in the search for her daughter.  "I'm not in control over any of this 'cause I don't know what's going on," she said in one exchange. "My entire life has been taken from me. You don't understand. I don't have any answers because I don't know what's going on. I can't even say anything to you guys. I want Caylee and that's not even getting put on the air, which it should be."  Then Cindy Anthony asks her daughter if searchers should be looking for anything in Lake County, Florida. That prompts Casey Anthony to threaten to hang up the phone.  "This is the first time I've truly been angry the entire time," she said. "I'm frustrated beyond belief."  She also complains about her isolation.  "You guys still have each other to lean on," Anthony told her parents. "I don't have anybody."  In another video that opened the day's evidence, Anthony praised her parents and said she just wanted to be home with them and her daughter.
