TUCSON, Ariz. -- A human skull with a bullet still inside, found by a family's dog last year has given authorities an idea of what a murder victim might have looked like.

The FBI made a facial reconstruction.  The person was between 18 and 30 years old with a large amount of dental work.

The skull was found on Orange Grove Road on the northwest side.

If you know who this might be, call 911 or 88-CRIME.
