UPDATE KNOXVILLE, Tenn. (WVLT) -- She's not speaking, but Vanessa Coleman's words are being heard loud and clear in a Knox County courtroom.

Coleman is the last person to be tried for the carjackings, rapes and murders of Channon Christian and Christopher Newsom back in January 2007.

Today prosecutors played tapes of Coleman during an interrogation inside the Lebano, Kentucky police department. On those tapes Coleman is heard lying to investigators about the extent of her knowledge and involvement in the Christian-Newsom killings.

Later, a prosecutor took the witness stand to play the role of Coleman as she testified before a federal grand jury. It was in this testimony that Coleman finally started to give authorities a glimpse into what really happened as Channon Christian and Chris Newsom were tortured and killed.

"I went into the back room and I seen him snapping on her neck like this, and then he began to choke her, sir, and that's when he started to yell at me to leave, to get out, get out," Coleman is heard saying on the tapes.

Coleman also testified that Davidson left the house several times while Christian was being held there.

Prosecutors are trying to show that Coleman was in the house of her own free will, and could have escaped if she was truly in danger.
