Vallow’s son accuses her of murdering his siblings. Vallow is also facing a charge connecting to her to the death of her husband's late wife, Tammy Daybell. The court also heard from more witnesses. A special agent with social security that helped investigate, detailing how Lori allegedly collected benefits on behalf of her kids months after the murders.
