Lori Vallow's Hair Found on Duct Tape Wrapped Around Son's Body, DNA Analyst Testifies.

A DNA analyst testified in court that a hair found on duct tape wrapped around the body of Lori Vallow's son, JJ Vallow, was a match for Vallow. Vallow is accused of killing her two youngest children and is also charged in connection to the death of her current husband's late wife. JJ's cause of death was asphyxia from a plastic bag over his head and duct tape over his mouth, while Tylee's cause of death was declared as "homicide by unspecified means."
