Public outrage over young mother Casey Anthony's acquittal is peaking and trial observers are saying that her independence was enabled by holes in the state's forensic case.

Casey Anthony was charged with homicide in the death of her two-year-old daughter Caylee and was acquitted July 5. Cause of death was painstakingly difficult to determine because of the advanced state of decomposition of the body when it was found in December 2008 in a wooded area near the Anthony home.

Anthony consistently partied after the child became missing, acquiring a new tattoo with the Italian words for Beautiful Life and entering herself into a hot body contest.

Anthony's parents George and Cindy Anthony released the following statement: Despite the baseless defense chosen by Casey Anthony, the family believes that the jury made a fair decision based on the evidence.

Anthony, 25, who said that a nanny had kidnapped her child and that she had been conducting her own search, maintained throughout the trial that her father had raped her since early childhood, enabling her to become a masterful liar.

The court used cutting-edge forensic evidence, which Anthony's lawyers dismissed as junk science. Still, others considered this method too experimental. One juror told ABC News after the acquittal that the state's case left too many questions unanswered, prompting a not guilty verdict.

An infantile method used to prove chemical existence of decomposition in the trunk of Anthony's car was used for the first time in the Anthony trial, said its creator. An uncommon method used to analyze hair for signs of decomposition was also presented to the jury.

Defense lawyer and forensic consultant Keith Murray told CNN that The judge really opened the doors for everything in this case. Maybe he thought, 'Let the appeals court deal with it.' Maybe he was punting. But in my opinion, none of it should have gotten into the trial.

Anthony was acquitted on four charges of lying to investigators but will be released tomorrow on good behavior and with credit for the time she has already served. Anthony, meanwhile, has appealed this conviction, which would force her to pay $4,000 in fines.

Casey's defense said that her life is in danger due to rampant death threats.
