i don't know the answer to that one. the police or mortuary will answer for you. there was a movie about this subject it was called "the sunshine cleaners" it wasn't morbid. it was uplifting.
I live in a large condo 55+ complex. We have had several people die (not murdered) ages 79-97. There are companies like "AA trauma cleaning service" 954-973-9502. Maybe they can recomend someone near you. Good luck
