A Virginia college student was charged with first-degree murder and abduction Saturday after his roommate was found dead.

According to MyFoxDC.com, Grace Rebecca Mann, 20, was found unconscious Friday in a Fredericksburg, Va., house by two female roommates.

Another roommate, University of Mary Washington student Steven Vander Briel, has been charged with first-degree murder and abduction in Mann's death.

One of the roommates performed CPR and Mann was taken to the hospital, where she later died, MyFoxDC.com reported.

Police told MyFoxDC.com that Briel was at the house when the other roommates found Mann, but fled the scene before police arrived.

He was arrested about two hours later after more than 20 police officers and K-9 units searched for him.

He was held without bond in the Rappahannock Regional Jail. It was not immediately clear if he had an attorney.

Mann is the daughter of Thomas Mann, a juvenile and domestic relations court judge in Fairfax County, and Melissa Mann, The Free Lance-Star reported.

Police have not revealed how Mann was killed or a motive.

The Free Lance-Star reported that Mann was active on campus and had recently been appointed to a sexual assault task force. She was known on campus for her passion for gender equality and civil rights.

"She was a remarkable young woman," said Leah Cox, special assistant to the president for diversity and inclusion. "I still can't quite imagine not seeing her on campus."

Briel attended Mary Washington from 2002 to 2007. He re-enrolled for the spring 2015 semester and was majoring in political science.

Counseling services were made available to students on a drop-in basis starting Saturday afternoon.
