A desperate search is under way at prestigious university after 18-year-old student vanished early Saturday morning. New surveillance video is offering up additional clues as to what may have happened to Hannah Graham.
Videos offer clues in search for missing University of Virginia student
Hannah is not the first young woman to vanish without a trace near the University of Virginia.
CNN's Joe Johns has the report.
Graham should have sobered up as the hour passed. But news stories say her texts became more erratic. Why didn't she call someone? The latest witness statement says he thought she acted distressed. That says she was suffering a little known mental event discovered by engineers when it caused mental breaks for office workers, Subliminal Distraction. Cubicles have been used since 1968 to prevent the psychotic-like episode of confusion in offices.
Students can create the "mental break causing design mistake" where they study or use a computer. The other current case is Anna Smith who vanished and was found a suicide.
There is a very long list of these disappearances. Some turn out as crime or accident victims. A large segment are suicides. A few recover and return in altered mental sates. And the last group are never found.
