Virginia authorities are investigating a possible link between the man accused of abducting Hannah Graham and at least three other cases of young women either murdered or missing.
The investigations include a cold case that involves a 23-year-old, who vanished near Liberty University in 2009. It's the same school where Jesse Matthew was once a student and accused of sexually assaulting another student 12 years ago.

An Oklahoma man may face the death penalty for allegedly beheading his co-worker, according to the district attorney in the case.
Officials say the suspect, Alton Nolen, "didn't like white people" and had an "infatuation" with beheadings. Nolen had just been suspended from his job at a food processing plant and attacked the first person he saw there.

(CNN) - Rep. Paul Ryan doubts President Barack Obama will be able to maintain his promise that there will be no American boots on the ground in the fight against ISIS.
"I'm supportive of what the President has done going into Syria and Iraq, but you have to see this thing through," the Wisconsin Republican said Tuesday on CNN's "Erin Burnett OutFront."
Obama suggested in an interview with CBS' "60 Minutes" that his policy of sending no U.S. combat troops will stay in place. The situation in the region is more a political problem than a military one, he said.
According to a CNN/ORC International poll, the overwhelming majority of Americans (73%) support the current airstrike campaign but less than four in 10 favor sending combat troops into Iraq and Syria.
If Obama's administration ultimately comes to Congress with a plan to send combat troops to Iraq and Syria, Ryan said he would support it.
"I think the President should come to Congress with an authorization of force resolution and I would support it," he said. "And I would help the President pass that because I think it's necessary to see this threat through."
"We need to destroy ISIS, and we need to do what it takes to destroy ISIS," he continued.
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.
Can this be a case of a serial killer?
