"This is a tragedy that snowballed out of control," Baez said. "This is not a murder case. This is not a manslaughter case ... this is a tragic accident that happened to some very disturbed people."  Anthony is accused of killing Caylee in 2008 and lying about it to investigators. The Orlando trial, which comes after nearly three years of legal twists, turns and delays, has garnered interest nationwide.  Anthony has pleaded not guilty, and denies harming her daughter or having anything to do with her disappearance. Baez has said that once all the facts are known, it will become clear his client is innocent.  In addition to capital murder, Anthony faces six other charges, including aggravated child abuse, aggravated manslaughter of a child and providing false information to authorities. If she is convicted by jurors -- seven women and five men along with five alternates -- she could face the death penalty.  Baez dropped another bombshell when explaining Anthony's behavior in the month before Caylee was reported missing on July 15 -- partying and lying about the child's whereabouts. "Casey did what she's been doing all her life, or most of it: hiding her pain," he said, adding that Casey Anthony had been sexually abused by her father starting at age 8.  Anthony was taught from an early age to behave as if nothing was wrong, he said, describing an incident where she went to school and behaved normally at age 13 after performing oral sex on her father. George Anthony sat stone-faced in the gallery as Baez made the allegations; Anthony put her head on the shoulder of another defense attorney and sobbed.  However, in his testimony, George Anthony -- the trial's first witness -- denied ever sexually abusing his daughter. He also said he was not at his home when Caylee died. "If I'd have known something happened to Caylee, we wouldn't be here today," he said as Casey Anthony shook her head.
