SALISBURY, N.C. -- Investigators now have surveillance video that might provide a clue as to what happened to missing teen Erica Parsons.
The video is from surveillance cameras mounted around a home across the street from where Erica was last known to have been living with her adoptive parents.
NBC Charlotte has learned that investigators have reviewed the video from the cameras, some of which dates back two years to the time when Erica was last seen at the house.
The owners of the home with the cameras did not want to be identified. They said that investigators have kept four video recordings but the couple doesn't know what, if anything, the cameras showed.
The owners said at least one of the cameras provided a picture of the Parsons' home and their driveway.
The adoptive parents, Casey and Sandy Parsons, have said that two years ago they took Erica to stay with a grandmother who lived in Asheville.
Investigators have said they do not believe that story is true and have not commented on the video and what it might show.
