DNA recovery and human identification from semen stains washed at different temperatures.

One of the most important pieces of evidence to find the suspect of a sexual assault are semen stains. It has been observed that suspects do not use condoms in many cases and transfer seminal fluids over the body of the victim, to their clothes, to bed linen, or to other objects in the environment. However, in many cases, it has been seen that the suspects or the victims tend to clean their bodies and clothes because of psychological conditions such as fear, panic, and anxiety.
