FREDERICKSBURG, Va. — Steven Vander Briel, 31, was sentenced to life in prison, plus 11 years, for murdering University of Mary Washington student Grace Rebecca Mann.
Vander Briel, of Fredericksburg, was convicted in May of the strangulation death.
The jury rejected the defense’s argument that Briel was insane when he committed the murder.
Mann was killed in April 2015.
Briel and Mann were roommates in Fredericksburg, where Mann attended Mary Washington and Briel was an on-again, off-again student.
Dr. Eileen Ryan, the medical director at the University of Virginia’s Institute of law, Psychiatry and Public Policy, diagnosed Briel with paranoid schizophrenia and said he believed people were trying to kill him.
