Hours after the victims are taken hostage, a ransom is delivered to the mansion on Woodland Drive. But it doesn't save the victims -- the calls, text messages and voicemails end, leaving key parts of the timeline unexplained. But after the trial, a new theory emerges explaining how the killer got inside the house. This episode is written and produced by WTOP reporters Megan Cloherty and Jack Moore.
