As the prosecution in the Casey Anthony murder trial prepares to rest their case, and the defense gets ready to present their side, a famed prosecutor tells Breaking Celebrity News that Casey Anthony MUST testify if she hopes to be acquitted.

Los Angeles Deputy District Attorney Danette Meyers, who is not directly involved in the Anthony trial, tells Breaking Celebrity News: "The defense has to establish what they said in their opening statements. Mr. Baez (Casey's attorney) said that Casey was molested by her father. Casey's father denied those allegations when he was on the stand. The only person that can establish that it did happen is Casey Anthony, period. Anthony has to impeach her father's testimony, it has to be countered and dealt with."
