What type of analysis would be useful if a rape victim reports being bitten by the suspect?

1. Analysis of fingerprints and blood types

2. Analysis of hairs, DNA under fingernails, and bite marks

3. Examination of clothing for tears and stains

4. Review of security footage and witness statements

The correct answer is: Analysis of hairs, DNA under fingernails, and bite marks

In cases where a rape victim reports being bitten by the suspect, the analysis focused on bite marks, along with any biological evidence such as hairs or DNA found under the victim's fingernails, is essential. This type of analysis is directly relevant because bite marks can serve as a unique form of identification, potentially matching the suspect's dental records or providing other forensic leads. Bite marks may carry unique characteristics that can be linked to a specific individual. Additionally, any hair or DNA found under fingernails can offer crucial evidence connecting the suspect to the crime, as it may come from the assailant during a struggle. This combination of evidence can significantly strengthen the investigation by providing tangible links between the suspect and the act of violence. The other options, while they may contribute to the overall investigation, do not specifically address the particular type of evidence and analysis needed in respect to the victim’s report of being bitten. Analyzing fingerprints and blood types might be useful in a broader context but does not directly relate to the bite incident. Examining clothing might help in establishing context but would not provide specific evidence related to the bite. Reviewing security footage and witness statements can provide information about the crime but may lack the specific forensic evidence that directly correlates to
