Scientific Approach to Evidence Collection

In  3–5 pages, excluding the title and reference pages, discuss the  scientific approach used to identify and collect various types of trace,  blood, and/or other biological evidence that has the potential to  resolve a criminal investigation.

1. Provide  a detailed example of clues that can be gleaned from the detailed  observation, examination, and analysis of at least two specific types of  trace and/or biological evidence.
2. What  procedures must be followed by the crime scene investigator during the  evidence collection process to ensure that accurate and reliable  scientific results can be obtained from a forensic analysis of the  evidence?
3. Include in your paper how a crime scene investigator would defend their research in a court of law.
