A human skull was found near the River Spirit Casino near 81st street on Saturday night.
The skull was found by a worker at the casino.
The FBI and the Medical Examiner's office were called, and after searching the area, they found a foot and rib.
All three bones appear to have been there anywhere from six months to a year.
There was no blunt force trauma or any kind of damage to the skull.
The medical examiner's office will now look to obtain DNA off of the remains.
