A forensic scientist testified at Doomsday mom Lori Vallow’s trial stating fingerprints found on a bag containing her son’s body are his adoptive uncle’s prints, according to authorities.
Martinez added that the prints were latent, meaning they are invisible to the human eye because the impression is created from sweat or oil, according to East Idaho News.
Cox died months after the boy’s disappearance, but Arizona police provided Cox’s fingerprints to Idaho authorities, officials said. In July 2019 – months before J.J. and Tylee Ryan’s disappearances – Cox fatally shot Charles Vallow in Arizona.
During her testimony, Martinez said she also obtained fingerprints from Lori and Chad Daybell, as well as hair samples and footprints. Chad is Lori’s fifth husband and they have been charged with killing Lori’s two children, as well as Tammy Daybell, who was Chad’s wife. Tammy was killed in Idaho in October 2019.
