An autopsy did not rule on the cause and manner of death and is still pending, according to the medical examiner’s office.

Crisis responders are helping the Griffin family cope, but said it is especially difficult given the horrific way Demetrius was killed.

“No one needs to go through that pain,” said Andrew Holmes, Crisis Responder. “It’s enough that you know they have to identify them once they’re shot, but then you got to go through DNA, giving up blood samples to make sure that’s your baby. That’s some pain. You can pain all night and day and all year and the rest of your life on that. That something a parent don’t want to go through.”

Police are still conducting a death investigation. No one was reported in custody, police said. They are asking for help in locating the suspect, and said whoever started the fire may have suffered burns.
