An Idaho mother is desperate for the return of her two missing teenage children, fearing they may have been abducted by members of the Fundamentalist Church of Jesus Christ of Latter-day Saints. Elizabeth Roundy reported her 13-year-old son, Allen Larand Fischer, and 15-year-old daughter, Rachelle “Shelly” Leray Fischer, missing Sunday. Authorities issued an Amber Alert for the siblings, who were last seen between 6 and 8 p.m.
