The arrest of Jesse Matthew - the suspect in the disappearance of University of Virginia student Hannah Graham - has resulted in a "significant break" in the 2009 death of another young woman in the same area, police said.
Virginia State Police say there is a "new forensic link" between the Hannah Graham case and the death of Morgan Harrington, a 20-year-old Virginia Tech student, who went missing after attending a Metallica concert in Charlottesville in October 2009. Her remains were found on a farm months later.
Between 2009 and 2014, at least four women, including Harrington have gone missing along the Route 29 corridor that runs through Virginia.
