Audio of Casey Anthony's July 16 interview with investigators reveals deception, voice-analysis expert says Very very interesting. Must read! http://www.orlandosentinel.com/news/local/orange/orl-caylee1308sep13,0,6848116.story Investigator: Who exerts the most pressure on you? Anthony: Um, my mom does, absolutely. Why is this important? Friends told investigators that Anthony and her mother had problems in the past, including Anthony stealing money from her family. However, Cindy Anthony described her daughter as her "best friend" during an unusually detailed bond hearing in July. Constantine: "I am not convinced by Casey's tone in her voice that she felt controlled by her mom. A genuine emotion is lower and softer. Her words were not congruent with her vocal tone."
