Police are expanding their search in Charlottesville for a missing University of Virginia student after an eyewitness reported seeing her around the time she disappeared.

Police Capt. Gary Pleasants said Wednesday searchers are canvassing businesses in the city's Downtown Mall where an eyewitness reported seeing Hannah E. Graham early Saturday morning. He said police also have a second video that shows Graham running down a street.

Police said Tuesday that another surveillance video showed the 18-year-old Graham walking outside a bar.

Graham's friends reported her missing Sunday. They last heard from her Saturday morning, when she texted a friend after leaving a party and said she was lost.

Charlottesville Police Chief Timothy Longo has scheduled a news conference later Wednesday to update the investigation and to release videos showing Graham.
