I know that when a person passes, blood will pool in the lowest area. Ex: when a person chokes and dies on their back, their back will be bruised and swollen. But what if a person dies in water, or is put in water after death? If a person say, was given some concrete shoes, would the blood drain from the head and pool in the feet? I apologize for asking, but I want my story to be as accurate as possible. Thank you.
