I’m sorry, but there is nothing more that you can do here. It appears that all three passengers aboard this train were killed by the impact following its derailment. Based on your description of their remains, particularly the clothing of the eldest male individual, these persons are likely the Revered HaKiRozTuVa and two of his associates.
While your altruistic impulses are appreciated, continued inspection of the accident site may jeopardize criminal investigation. Please stand back and allow officers to complete their investigation, assisting only when requested.
