Very sorry for your loss.
If you do happen to have his body, you may send that to your state veterinary lab for a necropsy to be done. That may provide answers to why he was acting the way he was. If you do choose that route, he should be wrapped in plastic and set in the fridge, not the freezer to preserve his body.
