A piece of human skull found in Utah last year is back from the lab
but investigators still don't know where it came from.
Last July, a hiker found the remains just north of Westwater and called the Grand County Sheriff's Office.
Deputies sent the piece of skull to an FBI lab in Virginia but the lab could not pull DNA from the bone.
Investigators say they're now going to send the bone to an anthropologist for carbon dating. That should happen in the next few weeks.
