Police find more child body parts in Chicago park

(CNN) Authorities in Chicago say they don't know yet whether child body parts found in the city's Garfield Park are from the same body.

Over the weekend, after a human foot was discovered, searchers recovered the head, two hands, and two feet of a child, according to the police department and the city's medical examiner's office. Investigators found the hands and feet in a lagoon in the park on Saturday and officers continued searching into the night, video footage from CNN affiliate WLS showed.

A source with knowledge of the investigation said it was a citizen that made the first discovery in the park.

A search of the same area Sunday recovered the head.

Some of the remains were found in a plastic bag, authorities said.

As search teams returned to the same area on Monday, the medical examiner's office said a pathologist would begin the examination process.

The park, which is centrally located near Chicago's New West Side, remains closed.
