(CBS) — Chicago police have completed their search of the Garfield Park lagoon but did not find any additional body parts belonging to a dismembered toddler.

Last weekend, the toddler’s head, arms, hands and feet and a 20 pound weight were discovered in the lagoon. The child’s torso was never found. Draining efforts will stop Sunday afternoon and a temporary dam will be removed Monday.

The Cook County Medical Examiner’s office has said the body parts are from an African American or mixed race child between the ages of 2 and 3 years. The child most likely had short, curly black hair, brown eyes.

So far, police have been unable to determine the gender, race, or exact age of the child, but did release a composite sketch of the child.

Chicago police say they are working with the FBI and National Center for Missing and Exploited Children in order to identify the child and DNA and forensic testing are awaiting processing.

Anyone with information is asked to contact Area North Detectives at 312-744-8261.
