Charlottesville, Va. police executed search warrants today of an apartment and car believed to be relevant to the search of missing University of Virginia student Hannah Elizabeth Graham, who has been missing since last Saturday.

According to WVIR, police's investigation led them to a car, which in turn led them to an apartment in the Hessian Hills apartment complex.

A person of interest in the case was identified by police yesterday using security footage in which a man can be seen putting his arm around Graham just past 1 a.m. Saturday.

Police have been piecing together the timeline of Graham's disappearance after leaving a party last weekend—in more security footage, she can be seen running past a gas station shortly before texting her friends that she gotten lost on her way home.
