Hospital Had to Figure Out Who John Doe Is and This Pigeon May Have All the Answers

John Doe

Since the man came in with no identification cards, the staff had no way to confirm his age and identity. The old man was just able to make it to the hospital when a bystander saw him collapse in the street and called for an ambulance.

To make things worse, the doctors could not talk to the patient because he was in a coma. The old man had severe brain swelling from the fall so the doctors had to put him in a coma until the swelling went down. For now, the patient had to be referred to as John Doe.
