(AP) — A forensic clue uncovered in the investigation of a missing University of Virginia student has led investigators to believe they have "a significant break" in the unsolved death of another young woman who had vanished from the campus five years ago, police said Monday, and perhaps an unsolved rape from years before. On Monday, Virginia State Police said in a statement that the arrest "provided a significant break in this case with a new forensic link for state police investigators to pursue" in the death of 20-year-old Morgan Harrington, who, like Graham, vanished from the Charlottesville campus. The state police statement provided no specifics about what sort of forensic evidence led to the connection in the cases. Clint Van Zandt, a former FBI profiler, said he was not surprised by the new evidence. "Since this most recent victim disappeared, I said time and again that if they could find out who was responsible there was a good chance the same person would be responsible for Morgan Harrington and a number of others," he said.
