On the audio recording, Moore could be heard saying: "I'm not gonna get caught."
Authorities used Smith's recordings to help locate Shakespeare's body and the gun that killed him.
Claiming she was framed, Moore told detectives several times that a drug dealer named Ronald and his band of killers were responsible for Shakespeare's death and were targeting her.
"They were going to take my son and kill him and chop him up and put him on my doorstep," said Moore.
Moore maintained that she had several witnesses who could prove she did not kill Shakespeare, but she would not disclose their identities to ABC News' 20/20. Before ending the interview, she divulged just a single first name.
"Her first name is Dee-anna," Moore said. "I'll tell you that."
However, detectives said that "Dee-anna" was just another lie from a convicted murderer who is set to spend the rest of her days behind bars.
