CHARLOTTESVILLE, Va., Sept. 17 (UPI) -- On Wednesday, police in Charlottesville, Va., released a new video of missing University of Virginia student Hannah Graham.
Graham,18, has been missing since Sunday. Police said she vanished on her way home from a party early Saturday morning.
Police said a witness spotted the teenager enter an open-air mall the morning she disappeared.
Charlottesville Police Capt. Gary Pleasants said prior to the sighting at the Downtown Mall, a security camera at a nearby gas station captured video of Graham running by the store.
Pleasants said the video -- which was recorded just before 1 a.m. on Saturday -- showed no one chasing her.
During a news conference police said they believe Graham had lost her bearings. They said friends weren't worried right away because she spent a lot of time in the library.
By Sunday when they hadn't heard from her, Graham's friends called her parents.
