Opening statements began Wednesday for the man accused of killing his wife and the two youngest children of his then-girlfriend, Lori Vallow Daybell, in a series of "doomsday" slayings that prosecutors say were fueled by "power, sex and money."
“Doomsday Mom” Lori Vallow Daybell's autistic 7-year-old son, J.J., had a date-rape drug in his system when he was asphyxiated to death with a plastic bag and duct tape over his mouth.
FBI forensic anthropologist Angi Christensen, who examined Tylee Ryan's skeletal remains, testified on Wednesday that there was evidence of "carnivore activity" on the back of one of the girl's legs.
