Hannah Graham Death Ruled a Homicide, but Cause Unknown Medical examiner can't specify how UVa student was killed By John Johnson, Newser Staff Posted Nov 18, 2014 6:00 PM CST 2 comments Comments This undated file photo shows Hannah Graham, whose body was found last month. (AP Photo/Charlottesville, Va., Police Department, File) (Newser) – The state medical examiner's office says University of Virginia student Hannah Graham was murdered, but it can't determine how, reports NBC29 of Charlottesville. In official parlance, the cause of death is "homicidal violence of undetermined etiology." The remains of the 18-year-old weren't found until five weeks after she went missing in September. She was last seen with 32-year-old Jesse Matthew, who has been charged with her abduction but not with her slaying, notes the Daily Progress. Those charges could come at a court appearance in early December. Matthew has been linked to at least one other murder of a young woman.
