It can help to identify the criminal by determining the sexual history of the attacker. A woman describes being attacked by a masked attacker who she scratches on her arm. Although the victim provides a detailed description to the police of the attacker, she doesn’t know if it was male or female. There are many steps that can be taken to establish the sexuality of the attacker.
First, collect all evidence at the crime scene. This includes hair or clothing fibers. These samples can then be analyzed for DNA, which can provide important information about the attacker’s sex. Saferstein (2014) states that DNA analysis can be used to identify suspects and link them with crimes. 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 be used as a way 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.
