After months of speculation, Chicago Police confirm lab results from the FBI are a match for Kyrian.
13 News spoke with his mother, Lanisha Knox, over the phone after it was made public.
She sounded devastated as she could barely get through her short conversation with us.
While this announcement answers one question, there are still many more about what happened including who could do this to a child?
13 News has created a timeline of events in the Kyrian Knox case.
September 5: It was Labor Day Weekend. We learned disturbing details out of Chicago that a child's body parts were found in Garfield Park.
September 17: Rockford Police respond to a missing child call. Police said that call was made by the people caring for the little boy.
September 20: Rockford Police go public with the name: Kyrian Knox. At a press conference, Assistant Deputy Chief Pay Hoey said, "There is no evidence to support that he was abducted. This is not a random act."
The Rockford connection starts to emerge. We learned Chicago Police had come to Rockford to take a DNA sample from Lanisha Knox.
September 21: We spoke to her for the first time over the phone. We asked her if she felt like something happened to her son. She said, "I don't know." She went on to tell us she'd left her son with family friends while she was moving. She said she last saw Kyrian in mid-August, but said she would speak to him over the phone.
October 3: Lanisha Knox arrived in Rockford with a bus load of volunteers from Chicago to search for her son. She said at the time,"On the outside, I look perfectly fine, but on the inside, I'm a wreck." She maintained Kyrian's care was left to others when he disappeared. She said, "I honestly never knew he was missing because he was with my best friend's dad."
November 4: Chicago Police confirm what no one wanted to believe. That someone could've done unspeakable things to the little boy with the sweet smile.
Neither Chicago or Rockford Police would say if they're speaking to any suspects in this case right now.
