"Coroner Michelle Brown reported that it’s believed Morgan accidentally hit his head, leading to a fatal fall into the water"
How did the coroner arrive at this? It suggests that there is some blunt force trauma to his head? Where on the head?
Is he suggesting that he 'accidently ' hit his head walked or stumbled a unspecified distance collapsed and drowned ? Yes that's all possible its also possible that someone hit him on the head?
