LOUISVILLE, Ky. – The death of a 7-year-old boy at a Kentucky children’s residential center has been ruled a homicide by a medical examiner, and two workers at the center have been fired.

The Jefferson County’s Coroner’s Office determined Ja’Ceon Terry died July 17 of “positional asphyxia,” meaning his body position left him unable to breath. It provided no further details other than that the child was pronounced dead at a hospital.

At the time he died, Ja’Ceon was under the care of workers at Brooklawn, a children’s treatment center in Louisville. The facility provides care for “Kentucky’s most vulnerable youth and their families,” offering therapeutic foster care to children recovering from the effects of abuse and neglect, its website states.

As of Monday no charges had been filed in the case.

Louisville Metro Police spokesman Aaron Ellis said the case is the subject of an ongoing investigation.

“Once we have gathered all of the facts related to this death, we will present them to the Commonwealth Attorney’s Office to determine how we will proceed,” Ellis said in an email.

In a statement, Seven Counties Services, which operates the center for children with emotional or mental health needs, said it fired two employees involved in the incident.

The agency did not respond to a request by USA TODAY for the employees’ names, their titles and how long they worked for the company.

In the statement, the company wrote it was “completely devastated by the unspeakable loss of a child in our care.”

“He should not have died on our watch,” the statement continues. “As protectors of Kentucky’s most vulnerable children, we are dedicated to making sure it never happens again.”
