The easiest answer to this, for recent deaths, is use the place of death on the death certificate (ie. city, county, state, country). If you have more details, as Dave suggested, include the information and source in the biography. We have discussed before the fact that the death certificate doesn't show the actual place of death, but it is the legal record of the death. Currently when a person dies at home, or in an accident, they are taken to a hospital where they are pronounced dead by a physician and that becomes the place of death. I think this was what was agreed upon, someone correct me if I am wrong.
