After a lengthy investigation, Chicago police identified the child whose body parts were found in the Garfield Park Lagoon in September as missing Rockford toddler Kyrian Knox.

The boy was identified through DNA testing, Chicago Police spokesperson Anthony Guglielmi said Wednesday.

Police are investigating whether a 2-year-old boy who went missing in Rockford in mid-August is connected to the remains of a toddler found in the Garfield Park lagoon earlier this month. NBC 5’s Anthony Ponce reports.

Police took DNA samples from Lanisha Knox, the mother of 2-year-old Kyrian Knox, who was reported missing from Rockford earlier in September, according to Rockford Police Assistant Deputy Chief Patrick Hoey.

Kyrian's mother, Lanisha Knox, said she left her son with her best friend's family in Rockford on Aug. 18, and the family agreed to watch him for two weeks while she started a new job. Knox has not seen Kyrian since she dropped him off.

The details surrounding Kyrian's disappearance are under investigation, but Hoey said there is no evidence he was abducted, adding that the disappearance did not meet the criteria for an Amber Alert.

Knox said she made repeated attempts in early September to go to Rockford to pick Kyrian up, but the family who was watching him always made an excuse about why it wasn't good timing.

"At this point, I don't trust anyone and I do feel like somebody knows something and they're not saying anything," Knox said.

In September, authorities found several body parts belonging to a toddler in Chicago's Garfield Park lagoon. Police said they recovered two feet, two hands and a head, all belonging to a child. A 20-pound weight was also found near the body parts, but it has not been determined if the weight is related to the discovery.
