A grand jury in the United States has indicted Jesse Matthew Jr., who has already been charged with killing a Virginia university student, with the abduction and murder of Morgan Harrington, a Virginia Tech student who disappeared in 2009.

Harrington disappeared outside John Paul Jones Arena in Charlottesville, almost six years ago, while attending a Metallica concert on October 17, 2009. Her body was discovered on a rural Albemarle County farm in January 2010.

He is also charged with capital murder in the September 2014 disappearance and death of 18-year-old University of Virginia student Hannah Graham. Graham’s remains were discovered about 6 miles from where Harrington’s were found.

In November 2014, police forensically linked Matthew to Harrington. After police named Matthew a person of interest in Graham’s disappearance, he fled and was later apprehended on a beach in Texas.

He was convicted of abduction with intent to defile, a felony that empowered police to swab his cheek for a DNA sample. That sample connected Matthew to a 2005 sexual assault in Fairfax County, according to authorities.

Later in June 2015, Matthew entered an Alford plea in abduction, sexual assault and attempted murder back in September 2005. Under an Alford plea, a suspect concedes that there is enough evidence to convict but does not admit guilt. He is to serve life in prison for that crime.

"The indictments result from the dedicated investigative efforts over the past six years by the Virginia State Police, Albemarle County Police, Charlottesville Police, University of Virginia Police, and the FBI," state police wrote on Facebook.

Matthew is currently detained and awaits appearance in court on Wednesday, Sept. 16.
