Lori Vallow trial reveals disturbing details in death of her children.

The murder trial of Lori Vallow, the doomsday cult mom, has revealed disturbing details about the death of her 16-year-old daughter, Tylee Ryan. The FBI forensic anthropologist testified that Tylee's remains had evidence of "carnivore activity" and "sharp traumas" inflicted by a tool. Tylee's cause of death was ruled a homicide by unspecified means. Vallow and her husband are accused of murdering Tylee and her 7-year-old brother J.J. Vallow, who was asphyxiated with a plastic bag and duct tape over his mouth. The couple is also accused of collecting life insurance money and Social Security cash related to the three deaths.
