Lori Vallow Daybell, the Idaho mother with doomsday religious beliefs who was convicted of killing her two youngest children and conspiring to murder a romantic rival, is on trial again. The case has drawn public attention in part because Vallow Daybell, 51, has doomsday-focused religious beliefs. Prosecutors say she conspired with her brother to kill Charles Vallow, so she could collect money from his life insurance policy and marry her then-boyfriend Chad Daybell, an Idaho author who wrote several religious novels about prophecies and the end of the world.
