KNOXVILLE, Tenn. (WVLT) -- Convicted killer George Thomas has a new home behind bars in a maximum security prison, but not before an assignment at a less secure facility angered his victims' parents.

Thomas was sentenced to life in prison without parole for the January 2007 rapes and murders of Channon Christian, 21, and Christopher Newsom, 23.

Thomas had been serving that sentence a medium security prison, but was moved Tuesday after the victims' families called state lawmakers.

But the Christians are working to change more than where their daughter's convicted killers serve their sentence. They're also trying to change state laws.

Thomas was convicted on more on than three dozen charges in December, including the premeditated murders of Christian and Newsom.

Gary Christian says he was shocked when he learned Thomas was placed in the Northwest Correctional Complex, a classified medium security prison. Christian says State Senators Tim Burchett and Randy McNally worked to have Thomas moved to West Tennessee Penitentiary, a maximum security facility.

That's also where Thomas' friend and co-convicted killer Letalvis Cobbins is housed.

The Tennessee Department of Corrections says their cells are in different buildings, and they have no contact.

Inmates are placed in prisons based on a 30-day evaluation period at the state's intake center.

A TNDOC spokesperson said an inmates' crimes are considered, but an inmate's behavior is the main factor.

The Christians call that ridiculous.

"I just want to know, who do you have to kill in this state to be sent a maximum security prison?" Gary Christian said. "What is maximum security for?"

Senator Burchett has drafted a bill that he says would send any person convicted of first degree murder to a maximum security prison automatically. He's also sponsored a bill he says would gives lawyer's stiffer penalties for knowingly using false information about the victims. In other words, for putting the victims on trial with untrue information.

The victims' families were angered by convicted killer Lemaricus Davidson's defense team's tactics.

They say Channon and Chris were put on trial by the defense.

Davidson's attorneys argued the couple could've been buying drugs from Davidson, and not the innocent victims of a carjacking.

"The hardest thing I have ever had to do in my life by far, beyond any doubt, is sit in that courtroom and listen to those lies that they knew were lies, and for them to say it anyway because it was all they had," Christian said.

Davidson's attorneys declined to comment about their case, and said there are already ethical standards in place.

Both bills have just been introduced in Nashville. The regular legislative session started Tuesday.
