Advanced Criminalistics: Trace Evidence - Assignment Example

Advanced Criminalistics: Trace Evidence Describe the value (or lack thereof) of trace evidence from this scene. The presence of trace evidence in this scene is very significant as it helps in ascertaining that the crime was actually committed following the initial claim from the victim. This is so because some of the trace evidence found at the scene which in this case is a house under construction was also found on the victim. The trace evidence also was critical in identifying that the victim was actually at the scene.

The fact that the evidence from the victim matched with that collected from the scene confirms an indubitable link amid the two. Trace evidence also helped in ascertaining the accused by matching the evidence obtained from the victim, the scene and the suspect himself. From this scenario, there is direct transfer of trace evidence from the victim to the suspect and from the scene as well. This adds a lot of value to the trace evidence as this creates a link amid the three.Could you say that the suspect was at the scene?

Would you go so far as to say the suspect committed the rape based on cross transfer of physical evidence and the victims story? The indicted was at the scene because the trace evidence from the cloths that the suspect submitted for the investigations showed that the proof was transferred to the scene and to the victim. This would not have been possible if the indicted had not been at the place. Also, some item found on the suspect through a lab examination indicated that they appeared to have a common source with similar things found at the scene and on the victim.

Hence, confirm further illustrate that the suspect ought to have visited the scene where rape occurred. It is apparent to some extent, the suspect was in contact with the victim and that is why some of the evidence was apparent particularly from the victim to the suspect. The suspect at some point definitely had contact with the victim but it is not accurate to say that he committed the rape. This is because there was no conclusive proof from the DNA test conducted and therefore it is not clear without reasonable doubt that the suspect raped the victim.

The suspect could have come at the place after the rape had taken place thus prompting the transmission of the proof.How would finding one suspect pubic hair (by microscopic examination -- no nuclear DNA containing material attached to the hair and mitochondrial destroys the hair) in the victims pubic hair combing change your opinion? The presence of the suspect’s pubic hair in the victim’s pubic hair combing could definitely give an impression that the suspect actually committed the crime.

This though will be backed up with a series tests conducted on the pubic hair form the suspect and that from the victim. Bacteria mostly on pubic hair vary significantly across. Therefore, if there is a likeness with that of the suspect then that would imply the indicted actually raped.
