It can help to identify the criminal by determining the sexual history of the attacker. The following scenario shows a victim reporting being robbed by a man in a mask. She scratches her arm while fighting. While the victim has a clear description of her attacker to give the police, it is unclear if the attacker was male or a female. There are several ways to find out the gender of an attacker.
First, collect all evidence at the scene. This includes hair or clothing samples. These samples can then be analyzed for DNA, which can provide important information about the attacker’s sex. Saferstein (2014) says DNA analysis is one the best tools for linking suspects to criminals. You can extract DNA from blood, saliva, and semen.
Another step that can be taken is to examine the victim’s scratch marks on the attacker’s arm. Saferstein (2014) says that each person’s dermatoglyphics or skin ridge patterns can help to identify the suspect. The scratches left on the attacker’s arm can be compared to known samples of the victim’s fingerprints to determine if there is a match.
Lastly, an additional external source such as a Forensic Science International Journal, a Forensic anthropologist could be consulted to examine the physical evidence, including the victim’s scratch marks and any other physical evidence collected from the scene of the crime. You can.
