After Patsy called 9-1-1 claiming that her daughter was kidnapped and that the family had discovered a ransom note, she quickly attempted to hang up the phone. However, the operator recorded six seconds of what was previously unintelligible background conversation.

Using modern audio technology unavailable at the time, retired FBI profiler Jim Clemente and former criminal behavior expert Laura Richards managed to isolate what they believe is the content of the conversation.

According to the experts, one voice sounds like it could be JonBenet's father, John, saying, "Were not speaking to you." Another voice, which they believe to be Patsys, can be heard asking, "What did you do," followed by "Help me, Jesus."

A small child's voice, which the experts think could be JonBenet's then-9-year-old brother, Burke, asking, "What did you find?" After which, the female voice can be heard saying, "We've called the police, now what?"

Another new piece of evidence thrust into the spotlight was the ransom note, which has always been one of the strangest pieces of evidence for those who have followed the case.

The note, which many say shouldn't exist since JonBenet's body was found in the family's house hours after the 9-1-1 call, also strangely asked for the exact same amount of money as the bonus John got from his work that year.

According to test performed by Clemente and Richards, as well as forensic linguistics expert James Fitzgerald, the abnormally long note would have taken the writer a minimum of 20 minutes to scrawl, and that the note contained "materialistic language."

Finally, criminologist Werner Spitz joined the investigation and, through the use of some fake skulls and a demonstration of blunt force trauma, it was proven that a large Maglite flashlight discovered at the Ramsey residence could have been the murder weapon.

Additionally, Spitz said it would not have taken a great deal of strength to cause the damage, given that that skull of a 6-year-old child is very delicate. Meaning that it is conceivable that the murder was not necessarily committed by an adult.

The second half of The Case of: JonBenet Ramsey airs Monday at 9 p.m. PT/ET on CBS.
