Cumberland County Coroner Charles Hall said Friday that the boy was being kept on life support at Hershey Medical Center, where his organs were to be harvested for transplantation.
Hall says the cause and manner of death won't be released until after an autopsy planned for Monday. He's not identifying the boy at this time.
Police have said the child was shot by a 6-year-old boy on Sunday while an adult slept. Police documents allege the home wasn't fit for children because of trash and debris.
No charges have been filed in the case.
