Two motorcyclists riding on a trail found the woman's decomposed remains on June 17, 2012 in a wooded area off Quail Run Road in Pemberton Township.
Police believe the woman was white or Hispanic, between 25 and 40 years old and about 5' 6" tall.
She also had extensive dental work. In addition to the sketch of the woman, investigators released an image of the woman's dental x-rays.
Anyone who recognizes the woman pictured in the sketch is asked to call the Burlington County Prosecutor's office at 609-267-8300.
