Assignment: Based upon information learned from your text, in the websites listed above, and your own research, discuss the importance of the crime scene investigator's knowledge of these types of evidence. For example, what if the investigator was unaware that metal ions may be transferred to human skin during prolonged exposure? How could this impact an investigation?
Requirements:
- Your response should be in APA format and 450 - 550 words in length plus resources.

METALS IN TRACE ANALYSIS
The fact that metal ions can be transferred into human skin with enough exposure time gives the
investigators knowledge of the mode of crime and the exact location of crime scene
The knowledge of the detection of these trace metal ions gives the investigators with this
knowledge a upper hand in the investigation.
Since once these metal ions react with the Trace Metal Detection(TMDT)solution and fluoresce
ultraviolet(UV) light the color of the fluorescence can indicate the type of metal contacted.
This is mostly used in incidences such as self-inflicted gu...
