Police responded to the 17900 block of Joplin Road in Triangle Sunday at 1:28 p.m., after human remains were reportedly discovered in the area.
No other remains besides the skull have so far been found. The skull was taken to the Medical Examiner's Office.
It has not yet been determined how old the skull is or why it was in the park.
