Historical Timeline
As you read through the required materials for this week, you should come to realize
that forensic science has developed over time, and you should understand that
development is critical to understanding current forensic science principles and
processes as well as likely future developments. The information on the Forensic
Science History (Links to an external site.)Links to an external site.web page will
further your understanding of this progression.
Using the required readings for this week and two additional credible resources from
the Ashford University Library or another credible resource, create a historical
timeline describing the major events within the field of forensic science. Your
timeline should bullet point the significant events in forensic science, giving the
dates, a brief synopsis of the event, and if possible, the person(s) most responsible
for the event.
After you complete your timeline, analyse the event you find to be the most
significant, including why it is most significant and its overall effect on the
development of forensic science.
Guided Response: Your initial post should be at least 250-300 words in length using
APA 6th edition formatting. Support your claims with examples from required
material(s) and/or other scholarly resources, and properly cite any references.

Legal Issues Analysis
Written Assignment
Prior to beginning work on this assignment, read Chapter 3 in An Introduction to
Crime Scene Investigation, the two court cases, and the rulings in the required
resources.
Before any scientific evidence can be used in court, including what we commonly
refer to as forensic evidence, the court must determine whether that evidence is
admissible. In 1923, in Frye v. United States, the United States Circuit Court of
Appeals for the District of Columbia established what came to be known as the Frye
standard. The Frye standard held that expert opinion based on a scientific technique
is admissible only where the technique is generally accepted as reliable in the
relevant scientific community.
Seventy years later, in Daubert v. Merrell Dow Pharmaceuticals, the Court of the
United States held that the Federal Rules of Evidence superseded the Frye standard
as the standard of admissibility. Some states, however, still follow the Frye standard.
After reviewing the required materials and conducting your own independent
research into the relevant issues below by reviewing law review articles, treatises,
and related cases using Westlaw in the Ashford University Library or another legal
research site. Try looking in Legal Search Engines, Directories, and Other Research
Tools in the Southern Illinois University School of Law Library (Links to an external
site.)Links to an external site., which has links to numerous legal research sites.
The Legal Issues Analysis paper must include the following elements:
·
Discuss the current legal standard for introduction of scientific evidence.
·
Review the history of the standard.
·
Compare and analyze the Daubertstandard, the Frye standard, and Rule 702.
·
Discuss whether your state uses the Daubert standard or the Frye standard.
·
Evaluate whether Daubert or Frye is the more appropriate standard.
·
Evaluate the current standard. Is it satisfactory? If yes, why? If no, what would
be a better standard?
The Legal Issues Analysis paper
·
Must be approximately 1,000 words (approximately four double-spaced pages
in length not including title and references pages), and formatted according to APA
style as outlined in the Ashford Writing Centre.

Death Investigations
The death investigation is set apart from all other crime scenes not because the scene
itself is different (other than the likely presence of a dead body) but because of how
seriously the criminal justice system, and in fact, society itself, takes human life. As
you read through the required materials for this week, you will discover that there
are special issues that exist with regard to death investigation crime scenes. Using
the required readings for this week and two additional credible sources related to
death investigation crime scenes from the Ashford University Library (or another
resource for finding credible sources), identify and discuss the special crime scene
issues involved with a death investigation.
Include the following elements in your initial post:
Briefly explain all the special crime scene issues involved with a death investigation.
Discuss how the special crime scene issues involved with a death investigation are
typically dealt with.
Suggest whether there are alternative ways of dealing with these special crime scene
issues.
CRJ 622 Week 6 Final Paper | Assignment Help | Ashford University
Crime Scene Scenario Analysis
Throughout this course, we have explored topics in forensic science with special
emphasis on approaching, securing, and managing a crime scene; documenting,
collecting, and processing evidence; maintaining chain of custody; and presenting
evidence at trial. We have also looked at collection and analysis of fingerprints,
ballistics evidence, blood, trace evidence, tool marks, and impressions of tires and
footprints. This process is critical to locating, securing, and analyzing physical
evidence that will help solve crimes and to the admission of that evidence in court
in order to secure a conviction.
The final assignment for this course is an analysis of the Crime Scene Scenario from
Week One. You will analyze the crime scene and providioe a detailed, step-by-step
examination from initial discovery through admission of evidence at trial. Do this
by including the following:
·
Approach to the crime scene
·
Documentation of evidence
·
Collection of evidence
·
Processing of evidence
·
Maintenance of chain of custody
·
Presentation at trial
The following elements must be addressed in your Crime Scene Scenario Analysis.
Your analysis must address these elements for each potential piece of physical
evidence you locate at the crime scene:
·
Determine how the initial responders should approach the crime scene.
·
Analyze how initial documentation of evidence should be carried out. This
includes documenting both the overall crime scene and the location of various pieces
of evidence within the scene. Issues of photographing, sketching, and video
documentation of evidence should be addressed.
·
Analyze how evidence should be collected, including specific methods for
o Potentially hazardous evidence.
o Impression evidence.
o Easily contaminated or compromised evidence.
·
Explain how the evidence should be processed, including the basic scientific
analysis to be performed on each piece of evidence and the laboratory equipment
that will be utilized.
·
Analyze each type of evidence found in the scenario in terms of its historical
use in criminal cases.
·
Assess how the chain of custody will be maintained.
·
Evaluate how evidence will be presented at trial, including discussion of
foundation and introduction of new tests and technology, if applicable.
