The Forgotten (2009) - 1x07 - Railroad Jane

After a female skull is discovered near a railroad track, The Forgotten Network canvasses the area in search of the remaining bones. Information retrieved from an artificial kneecap takes the team to the Doe's only remaining relative, her sister, who is in a coma as a result of a horrific attack. Further developments lead the team to believe that these sisters may have taken on false identities. If they were leading new lives, whom were they running from? What secrets is the coma preventing Jane Doe's sister from telling? And will the person responsible for these vicious acts come back and finish the job?
