A prosecutor says a former hospital worker is expected to plead guilty in the high-profile slayings of two college students in Virginia.

Albemarle County Commonwealth's Attorney Robert Tracci (TRAY'-cee) announced the plea agreements in Jesse LeRoy Matthew Jr.'s cases Monday. Matthew is due in Albemarle County Circuit Court on Wednesday.

Matthew is charged with murder in the deaths of 18-year-old Hannah Graham and 20-year-old Morgan Harrington. Without the plea agreement, he could have faced the death penalty in the Graham case had he been convicted at trial. He's already serving life in prison for a sexual assault in Fairfax County.

Graham was a University of Virginia student who disappeared in September 2014. Harrington was a Virginia Tech student who vanished after attending a Metallica concert at U.Va. in 2009.
