Before the episode airs, E! Online has released a two-and-a-half minute trailer.
The show features interviews with former boyfriends, school friends, defense attorneys, journalists and acquaintances, such as Zenaida Gonzalez, aka Zanny the Nanny.
“If you wanted to hang out [or] go party she was always down,” former boyfriend Brandon Snow said of Anthony.
Anthony was on trial in Orlando from May 24 until July 5, this year.
She was found not guilty of murder, aggravated child abuse, and aggravated manslaughter of a child. However, she was charged with four misdemeanor counts of providing false information to a law enforcement officer.
She is currently serving probation for lying to police and is staying at an undisclosed location in Florida.
E! True Hollywood Story: Casey Anthony airs tonight at 10pm ET.
