Sarah, 3, and Jacob Hoggle, 2, vanished while in the custody of their mother, Catherine Hoggle. Hoggle told police she gave her kids away, but prosecutors accuse the Maryland mom of murdering them. Hoggle, who has been in a mental health facility since her arrest soon after they disappeared, indicted for their murders and moved to a jail.  Now nine years after the children went missing, murder charges against Hoggle have been dropped and the mom will not stand trial in their deaths.  Hoggle has consistently been ruled incompetent.
