The woman has been dead for approximately 40 hours.
We can arrive at this answer because:
- Livor mortis is the term that refers to the presence of dark or whitish stains on the back of corpses, where there has been a shortage or an accumulation of blood.
- This accumulation or lack of blood occurs due to lack of circulation and these spots are clearly visible in a body that has been without circulation for about 40 hours.
- With this, we can say that the woman's blood accumulated on her back, allowing the presence of a strong red stain when her body was found 40 hours after her death.
The presence of water in the lungs allowed the bacterial activity to decelerate, which caused the decomposition to occur slowly.
