“The police, once on the scene realized that this wasn’t a murder scene”
I don’t know. Could have been but long past 48 hours and the chances of finding the killer are long gone.
It might be difficult, the case is a little too cold. If memory serves, there are ancient sources that state that those fleeing the Roman destruction of Jerusalem and the Roman army in general hid in caves and in the hills and whatnot, and that remains were noticed after everything calmed down. No one would have disturbed the remains.
