Pierce County Medical Examiner investigators worked to figure out who the man was or how he died, but there are no answers yet.
They developed a composite sketch in hopes that the public can help identify the man, who was believed to be homeless.
He was 30 to 50 years old, 5 foot 5 and stocky. He was missing upper and bottom teeth. His right nostril was slightly lower than his left and he likely had a strong brow ridge.
Police said the man could have relocated to Tacoma shortly before his death.
