CHICAGO -- The slow process of draining the Garfield Park Lagoon continued Wednesday as Chicago police looked for more remains of a child.

Remains found over the weekend are believed to be those of an African-American boy between 18 months and four years old.

However, the Cook County Medical Examiner's Office says a mixed racial background cannot be ruled out,  and it is still possible the body is a girl.

Officers have been searching since Saturday, when someone called 911 to report a foot floating in the lagoon.

Police say the draining work and investigation could take two to four days.

Officers began knocking on doors in the neighborhood and handing out fliers to drivers in hopes of solving the case.
