Vallow is accused of killing her two youngest children, and is also charged in connection to the death of her current husband, Chad Daybell’s, late wife. Her children, Tylee Ryan, who was almost 17, and JJ Vallow, 7, went missing in September 2019. Later, their bodies were found on Daybell’s Idaho property.
The official cause of death for JJ is asphyxia from a plastic bag being put over his head and duct tape over his mouth, while Tylee was declared a victim of “homicide by unspecified means,” Ada County Coroner Dr. Garth Warren said Wednesday.
Earlier in the trial, KSL reports investigators said they sent a hair for testing that was found on the duct tape wrapped around JJ’s body.
On Monday, Keeley Coleman, a senior DNA analyst at Bode Technology in Virginia, testified that she received a hair attached to an adhesive, along with other pieces of evidence and three DNA profiles from Vallow, her former friend Melanie Gibb and Ryan, the East Idaho News reports. The hair on the adhesive matched Vallow’s DNA, she said.
“The probability of randomly selecting a random individual in relation to that profile” is 1 in 71 billion, Coleman testified, per the East Idaho News.
