Can blood from a crime scene be analyzed if it is diluted by rainwater?
It depends on the degree of dilution, represented by the amount of rain water in which the blood was diluted. If the amount of water containing the blood is small, chances are that the blood can be analized. Moreover, the blood must be contained in a puddle, not in a running rain water, because the dilution would become very weak, thus difficulting any precise analisys, which would be essential in terms of forensic issues. It depends also on the intensity of the rain. Heavy ones can take the blood droplets very far away. In fact, blood is not diluted by the running rain water, but it will be sparsely dissolved in water. Only when the rain stops, if it was not a heavy one, investigators could try to find blood vestige around. However, technically there are many methods used today to find tiny vestige of blood which could last for years on that place.
