The parents both testified repeatedly during their daughter's trial.
On Tuesday, a jury acquitted Casey Anthony in her daughter Caylee's death. Lippman says her parents were shocked that the jury found no evidence against her because prosecutors "did a fantastic job."
Lippman wouldn't answer whether the Anthonys believe their daughter killed Caylee. He denied the defense's claims that George Anthony and his son molested Casey.
Lippman said the Anthonys had hoped to get "some sliver of truth" about Caylee from their daughter during trial, but Casey didn't testify.
