CHICAGO (STMW) — Police are checking to see if the child’s remains found in the Garfield Park lagoon over the Labor Day weekend might belong to a Rockford toddler reported missing last week.

Kyrian Knox, a 2-year-old African-American boy, was believed to have been last seen in mid-August, Rockford police say. The boy had been staying with a family friend just before he disappeared, police say. Investigators don’t believe the child was abducted.
