Forensic evidence pointing to an uncle was unveiled Thursday during Lori Vallow Daybell’s murder and conspiracy trial.

Tara Martinez, who specializes in latent prints like fingerprints, tested a variety of materials from the evidence bags she was given.

The Idaho Press reports Martinez looked at several samples of duct tape and the black plastic bag J.J.’s body was wrapped in.

On the black plastic bag she found a fingerprint and a palm print that matched the prints she had on record for Lori’s brother Alex Cox.

Cox has been a central figure in the murder case.

He died in December 2019.
