Were the photos from the medical examiner or funeral home ( that FIL took) ? I can’t imagine a medical examiner would release that quickly. I also can’t imagine the funeral home would allow a family in the preparation room. Maybe it is different outside the US. In the US exposure to embalming chemicals, regulations and pure respect for families would never allow any family member in that area. In the US if a family member posted pics from a prep room the inspectors would descend the next day! I work in compliance in this area and am all kinds of upset. Are the pictures from family or were provided to family?
