ORLANDO, Fla. – Local 6 has been digging through hours of phone calls made by Robyn Adams, a confidant who traded hundreds of pages of letters with Casey Anthony.
"Daddy, I'll do anything," Adams said in one call. "I'm so scared."

In the audio, Adams sounds terrified and states that she is willing to do anything to get out of jail -- but does that include using Casey Anthony for her own benefit?
Local 6's investigative reporter Tony Pepitone has listened to hundreds of calls made by Adams from the Orange County Jail, and the prosecution in the Anthony case said they believe there may be evidence contained in them.
Despite that claim, Pepitone said the calls do not show any attempt to make up evidence against Casey Anthony to help secure Adams' freedom.
Two months after she was sentenced to 10 years in prison, Adams called Tracy Neally, a friend she's forwarded hundreds of pages of Casey Anthony's letters to.
"I'm doing the right thing by holding onto the letters, I think," Adams said in another call. "I've got them all."
Now, prosecutors do too. The letters were released earlier in the week, and showed Casey Anthony opening up to a friend in jail; however, they do not include some of the more damaging things Adams claims Anthony told her verbally.
Some of the things Adams claims Anthony told her include knowing that Caylee's body was found in a black garbage bag with a blanket days before that information was made public.
In listening to the calls, however, it became clear that in March 2009, Anthony let something "slip" to Adams.
"It was kind of a fluke -- like it slipped," Adams said. "You know what I mean?"
Though the call does not reveal what the slip may have been, Adams did say she's considered telling others.
"I mean, if it would help me, you know," she said.
In a letter to Neally from April 2009, Adams said she hopes something she learned from Anthony could help reduce her sentence.
"This may be my only way out of prison sooner than my expected term," she wrote while sending along another batch of letters from Anthony.
Yet, in calls to her father, Adams also shows acts of friendship toward Anthony.
"Will you please send me a blank birthday card? It's Casey's birthday next Thursday," she asked.
The jail supposedly does not allow inmates to pass notes amongst themselves, but the volume of letters show that wasn't the case with Anthony and Adams.
However, many of Adams' claims -- including that Anthony admitted to medicating Caylee to "knock her out," or knew details of Caylee's remains -- are not contained in the letters written by Anthony. Adams claims Anthony told her those details face to face.
