The search for clues in a six-year missing person case is now in its third day.

A crew of volunteers led by state archaeologist Jonathan Leader have resumed excavating a plot of land on the old Navy Base about a mile from the apartment where Brandy Hanna was last seen on May 20, 2005.

North Charleston detectives recently found a shoe that may have belonged to Hanna on the site. The area is just south of Riverfront Park and is not accessible to the public.

As of Wednesday morning, the crew was working slightly more inland on the waterfront lot, leaving the search completely beyond public view.

The search is scheduled to end today, but Leader said Tuesday they would work until the whole area was searched.
