DENVER -- Investigators are asking for the public's help to identify a young boy who may have been murdered.

His body was found in a blue canvas laundry bag on Oct. 8, 2005. His body was discovered in the Chicago-area but detectives there believe he may be from as far away as Colorado.

Computer-enhanced images show what the boy likely looked like. The new rendering, the third, was created by Louisiana State University's FACES laboratory, which used clay to make a three-dimensional representation of the boy's face, using his skull.

A forensics artist did the first drawing and the National Center for Missing and Exploited Children did another.

The child, possibly East Asian or American Indian, Hispanic or Caucasian, was believed to be between 3 and 5 years old and weighed about 25-30 pounds.

He was dressed dark blue button down shirt, and dark blue pants, both with the brand name "Faded Glory," which is a brand exclusively sold at Wal-Mart.

Authorities in Illinois sent out the same images of the boy to police departments all over the country hoping to spark new interest in the case.

"Once again we are appealing to the public for their help in this case. We are still waiting for that one person to call us with the information that will lead us to the identity of this little boy," Sheriff John E. Zaruba said. "I am hoping that this photo is the one that clicks in someone's mind and helps us give this little boy his name."

An $11,000 reward is available to anyone who provides information that leads to the identity of the child.

If you have any information about the boy's identity, you're urged to call Denver police or call the Dupage Sheriff's Office at (800) 669-7109.
