Jury deliberations continue Friday in the highly publicized double murder trial of Richard Allen – who is accused of killing two teenage girls and leaving their bodies near a hiking path in the small town of Delphi, Indiana, more than seven years ago.

Prosecutors told the jury that this trial centers around three key pieces of evidence: the brutal killing of two young girls, a video taken by Abby Williams before her disappearance showing a man known as "the bridge guy," and an unspent bullet casing found at the scene. Investigators claim the casing matches a gun owned by Allen.
