The dismembered body parts of a small child found floating in a Chicago park lagoon in September have been identified as those of Kyrian Knox, a 2-year-old Rockford, Illinois, boy who was reported missing in Rockford in September, police confirm to PEOPLE.

“It is Kyrian,” Officer Thomas Sweeney, a police spokesperson, tells PEOPLE. “He was identified via DNA analysis.”

The boy’s family was devastated by the discovery, according to the Chicago Tribune. “My heart is hurting right now,” his grandmother, Cameshia Harris, told the newspaper. “The family is together and we are trying to wrap our minds over it.”

Kyrian was believed to have been last seen in mid-August but was not reported missing until Sept. 17, Patrick Hoey, Assistant Deputy Chief of Police in Rockford, tells PEOPLE.

Kyrian’s mother, Lanisha Knox, told WREX channel 13 that family friends in Rockford had agreed to care for her son while she moved from Cedar Rapids, Iowa, to Chicago, and she dropped him off on Aug. 18.

Two tiny feet and two hands were discovered Sept. 5 floating in the water at Garfield Park in Chicago. A child’s head was found late the next day.

Authorities took DNA samples and distributed a sketch in an effort to identify the child, and police started draining the 1 million-gallon lagoon to try to recover additional body parts or other evidence.

Authorities also took a DNA sample from Lanisha Knox and submitted it to both Rockford and Chicago authorities, Hoey says. Chicago police publicly confirmed Kyrian’s identity on Wednesday.

“Our missing person’s case ends with that confirmation,” Hoey says. But he adds, “There’s no sense of relief when a child is found murdered.”

Hoey tells PEOPLE that the family friend reported Kyrian missing on Sept. 17. Lanisha Knox said she found out that same day that her son was gone after being notified by police, she told WREX.

No one has yet been charged in the case, police said.
