Lori Vallow's Trial Unveils Shocking Revelations.

Lori Vallow's son, Colby Ryan, testified in court that his mother murdered his siblings, Tylee Ryan and Joshua "JJ" Vallow, who were found buried in Chad Daybell's backyard. Prosecutors allege that Vallow and Daybell, fueled by their doomsday-focused religious beliefs, killed the children and later conspired to kill Daybell's first wife for insurance and social security funds before fleeing to Hawaii. Vallow has pleaded not guilty to murder and other charges. Ryan is the first family member to take the stand against his mother.
