Both the prosecution and now the defense have rested in Richard Allen's murder trial in Delphi, Indiana, setting the stage for closing arguments Thursday.

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.
