Everybody walks around thinking that the mind is located somewhere in the body. The usual assumption is that the mind is somehow in the head. We now know that the mind is not really located in any specific place in the body.
Nobody can really say where the mind is at all.
There's no way of proving that it is in the head or even in the body. We don't destroy a being by destroying a body but simply destroy the communication device that person used. The body is simply a construct that is the result of thought. Perhaps the body is a construct in the mind like there can be a construct in a computer. A three-dimensional construct inside a computer is said to be virtually real.
