Investigation Discovery is airing a three-night investigation into the death of two-year-old Caylee Anthony. Her mother, Casey Anthony was tried and acquitted of aggravated manslaughter, aggravated child abuse and first-degree murder in 2011. This was a case that the whole world seemed to follow at the time and has been discussed a lot over the years.

The channel known for real Crime investigation will take an in-depth look at the case. For the first time, viewers will see interviews with Casey Anthony's parents, George and Cindy. Casey, however, did not give an interview for the show but did give an interview to Associate Press.

What is Casey saying after all these years?

In that interview, Casey says that the doesn't care what people think of her and she sleeps well at night. While she has never outright accused her father of murdering young Caylee, she has hinted at it. She claims that cops stick together and her dad is an ex-cop. She even went so far as to say that cops victimize victims.

George and Cindy Anthony did not take her comments without striking back. Their attorney, Mark Lippman, made a statement for People saying that they had all tried to move on from this. George has already been through the veiled accusations by his daughter and has been vindicated. He shouldn't have to go through all of this again.

Retired judge speaks out!

Belvin Perry, Jr. was the judge on the bench in 2011 and is now retired. He will be featured on "Casey Anthony: An American Murder Mystery." The Orlando Sentinel recently reported that he has stated he believes that Casey may have accidentally killed Caylee with chloroform.

Other interviews will include Clint House who was a friend and confidant to Casey at the time of the murder.

Alternate juror Russ Huekler, who faced just as much backlash from the verdict as the seated jurors, will speak as well. Viewers will also get the chance to see footage of Casey Anthony that has not been made public before.

Casey Anthony, now 30 years old, continues to live in South Florida in Patrick McKenna's home. He was the lead investigator on her case, and she now works for him doing investigative work.
