SUSSEX COUNTY, Va. (WVIR) - The man responsible for murdering Morgan Harrington and Hannah Graham has been transferred to another prison in Virginia.

Jesse Matthew was moved to a facility south of Richmond this week after being diagnosed with cancer.

On Tuesday, May 21, the Albemarle County Commonwealth's Attorney's Office alerted the mother of Morgan Harrington that Jesse Matthew is being transferred to a new prison as he undergoes treatment.

Matthew, who pleaded guilty to the murders of Graham and Harrington back in 2016, was serving his time at supermax (super-maximum security prison) facility Red Onion State Prison in Wise County.

On Tuesday, Gil Harrington, Morgan’s mother, says she was told Matthew would be transferred to Sussex 1 State Prison, which is south of Richmond.

Harrington says she worked for a long time to help keep Matthew behind bars, and hopes it stays that way.

“I'm not gleeful that he has this health challenge, but I'm not saddened by it,” Harrington said. “And perhaps it’s his fate or his destiny or his karma, I'm OK with what happens to him as long as he has been and will be contained.”

Officials have not yet confirmed where Matthew will be receiving treatment.

Albemarle County Commonwealth's Attorney Robert Tracci released a statement Tuesday night:

"The Virginia Department of Corrections notified parties late afternoon yesterday of its intention to transfer Jesse Matthew. Upon learning of this development, I advised the parents of Morgan Harrington and Hannah Graham and await further clarification from the Department of Corrections pertaining to the timing of and rationale for this decision. Under the terms of the 2016 guilty plea entered in the County of Albemarle, Mr. Matthew is not eligible for early release or parole."
