Updated 10/14/08 – Casey Anthony has been indicted by a grand jury on seven counts including 1st Degree Murder and is in police custody. More info here.
In response to a public records request by the Orlando Sentinel the Florida State Attorney has released nearly 600 more pages of documentation in the case against Casey Anthony. The documents include interviews with family members and other material and are part of the Discovery process, which is when the prosecution releases information to the defense.
I have to assume right now that the documents are related to the several different charges she is currently facing which include fraud and theft.
