Help with homework assignments


Unit I Homework

This homework assignment will consist of two parts: developing your curriculum vitae (CV) and writing a reflective paper.

A CV is an expanded and more detailed version of a resume and is often the preferred document for fire investigators. If you are not familiar with the construction of a CV, you may want to research online or within your own workplace environment to find examples.

SEE BELOW FOR EXAMPLE to access an example that can be used as a guideline in compiling the information for your own CV.

After completing your CV, you are to write a one-page reflection that addresses the areas below.

1. Identify professional development opportunities you can pursue that will augment your CV and help you progress toward the job performance standards identified in this unit’s textbook reading (NFPA 1033 Matrix).

2. Include your analysis of how various professional fire organizations can assist in your development and training.

3. Reflect on how increased professional development will affect your role in future fire investigations, especially those involving death and injury.

Your homework assignment will include your CV and your one-page reflection; however, both sections should be submitted as a single document with a title page.

Additionally, you may want to do your own research to view real examples of fire scene sketches or drawings. The goal of this assignment is to ensure that all relevant data is captured in your documentation of the scene.

To accomplish this, you will organize and sketch a hypothetical structure fire scene as if you are documenting the scene as a part of a fire report. You will create the specific details of the fire scene.

Your sketch should give a complete picture of all the necessary details that should be contained in a sketch, which would be a part of an official fire report. At a minimum, your sketch should include the following information:

“Identifying information such as address, date, time, case/incident number, and sketch author; a legend to describe what the symbols in your sketch represent; measurements, scale, and directional orientation (if not drawn to scale, it should be notated as “not to scale” or “all measurements are approximate”); and pertinent fire scene information and evidence such as damage, fire patterns, and fire travel (as presented in in the readings for this unit).

Next, write a single page narrative explaining your method of examining the fire scene and your method for compiling your documentation. Discuss the findings presented in your sketch to include sources of ignition, fire flow patterns, and ventilation issues.

Your project submission should be at least two pages in length.

Please include a title page with your submission. References are not required for this project. Information about accessing the grading rubric for this assignment is provided below.

Unit IV Essay

A majority of fires may require you to rule electricity in or out as an ignition source. The textbook discusses several sources of ignition by electrical means to consider during an examination of a fire scene.

For this assignment, you will choose one of the possible electrical sources mentioned in your textbook. Using the CSU Online Library, you will conduct your own research on that source of ignition. You will then write an essay addressing, at a minimum, the areas described below.

“Identify the approach you would use in investigating a fire scene where your selected source of ignition is suspected. Identify specific issues you should look for with this source of ignition to assist in determining the probable cause of the fire. Discuss safety measures that must be taken during the investigation when dealing with your selected source of ignition. Describe how arc mapping can assist in determining the area of origin, and in your opinion, if it is effective and reliable.”

Your essay should be a minimum of two pages in length, not counting the title and reference pages. You must use a minimum of three sources. All sources used must be properly cited. Your essay, including all references, must be formatted in APA style.

Unit V Project

Fire investigators routinely work in settings that are, without a doubt, hazardous to their health. When investigating a suspected drug laboratory scene, emergency personnel and investigators must consider the potential for the scene to have been either an explosion or explosive combustion.

For this assignment, you will create your own safety checklist for investigating a fire scene with suspected drug laboratory indicators. This is not to be a copy or revision of an existing checklist.

Your checklist should include measures designed to identify and mitigate safety and security issues unique to a drug laboratory fire/explosion scene. Your checklist should include measures that address, at a minimum, the areas listed below:

Steps in determining if hazardous materials are present or were involved in the fire; steps in safely identifying signs, chemicals, and/or hazardous materials that would indicate the fire/explosion scene was possibly a drug laboratory; the differences in safety measures when dealing with explosions and explosive combustion; and any specific training or equipment that may be needed in a drug laboratory fire/explosion scene response and investigation.

In addition to your checklist, you will write a one-page narrative discussing and supporting the need and importance of the steps in your checklist.

You may create your checklist in any format you feel would be most useful and presents a professional appearance. You may consider creating a table in Word or Excel or simply using a bulleted list. (one page for the checklist and one page for the narrative) in addition to the title and reference pages. You must use a minimum of two sources. All sources used must be properly cited; all references should be formatted in APA style.

Unit VI Essay

The National Fire Protection Association (NFPA) and the Federal Bureau of Investigations (FBI) both include the term willful and malicious burning of property in their definitions of arson; however, many states have drafted their own definitions and statutes relating to arson.

For this assignment, you will research your own state’s definition, statutes, and laws pertaining to arson. You will then write a well-organized essay about arson that addresses, at a minimum, the areas described below.

“Begin with an introduction to arson that includes discussion of the basic elements of proof needed to classify a fire as arson. Identify differences between arson and incendiary fires. Compare and contrast your state’s definition and process of arson investigation to those of the NFPA and FBI. Identify areas of your state’s statutes where you feel improvement is needed to cover areas not currently addressed.”

Your essay should be a minimum of two pages in length, not counting the title and reference pages. You must use a minimum of three sources, one of which may be your textbook. All sources used will be properly cited. Your essay, including all references, will be formatted in APA style.

Unit VII Project

For this assignment, you will be given a scenario and must prepare a final fire investigation report summarizing your investigation findings and conclusions in a methodical manner. You should incorporate the knowledge you have gained thus far in this course to ensure your approach is scientific and addresses the requirements of a thorough fire investigation.

The details for the incident as well as photographic evidence from the fire scene can be accessed by clicking As you will see in the document, the report requires you to provide a sufficient narrative and address, at a minimum, the following topics in your report:

Origin of fire (locations and fuels); combustion properties and extent of damage, from the sources to final points of ignition; causation (according to NFPA classifications); evidence; and estimated value of overall loss (for insurance company report).

Note: All the missing values in this project should be simulated and based on values known or found from publications or Internet research. They should be as real- world as possible in order to reflect a real case scenario.

You may use a standardized fire report template from your own workplace, or you may simply follow the outline in the document to create your narrative and report all findings.

Your fire investigation report should summarize your findings and conclusions in a logical and organized manner. You should describe the process that you use as you document the evidence. Assume this is a fire report that may later be used in a criminal investigation or prosecution. Remember, details, proper procedure, evidence, and referencing of relevant science may make or break the case.

Your fire investigation report should be a minimum of two pages in length, not counting the title and reference pages. External sources used in your report should be properly cited, and the references should be formatted in APA style.

Unit II Article Critique

Reference: LENTINI, J. J. (2015). Contextual Bias in Fire Investigations. Brief44(3), 40-45.

Scientific vs. Investigative Data

Contextual bias is an issue that has come to the forefront of forensic science in the last few years, and nowhere is contextual bias more likely to influence scientific determinations than in fire investigation. This is largely because many fire investigators also serve simultaneously as law enforcement officers.

This article will explore the different duties, responsibilities, and ethical requirements of the scientist and the law enforcement officer. What data constitute scientific evidence and what constitute investigative information? Can the two be separated? Should they be separated? How does the science suffer when the scientist is influenced by contextual bias? How does law enforcement suffer when a fire investigator is unable to classify a fire based on the physical evidence?

There are no easy answers to these questions. In one case, the ethical and valid response may be obvious, while in the next case, a fire investigator attempting to assist the jury to understand the physical evidence can easily cross the line and conflate valid, but domain irrelevant, investigative data with scientific proof. It is up to counsel to help the expert witnesses delineate between information that can potentially bias the interpretation of the physical evidence, and information that is necessary for its objective evaluation.

"Scientific" Knowledge vs. "Investigative" Knowledge

The fire investigation profession some time ago committed itself to conducting scientific investigations. The result has been a significant improvement in the reliability of origin and cause determinations. In the intervening years, the "relevant investigative community," represented by the National Fire Protection Association (NFPA) Technical Committee on Fire Investigations, has tried to root out those practices that make arriving at a valid scientific conclusion about the origin and cause of the fire more difficult. One of the obstacles to reaching a valid conclusion is cognitive bias.

The concept of expectation bias was first introduced to NFPA 921: Guide for Fire and Explosion Investigations in the 2008 edition, when the following caution about expectation bias was added.

4.3.8 Expectation Bias. Expectation bias is a well-established phenomenon that occurs in scientific analysis when investigator(s) reach a premature conclusion without having examined or considered all of the relevant data. Instead of collecting and examining all of the data in a logical and unbiased manner to reach a scientifically reliable conclusion, the investigator(s) uses the premature determination to dictate investigative processes, analyses, and, ultimately, conclusions, in a way that is not scientifically valid. The introduction of expectation bias into the investigation results in the use of only that data that supports this previously formed conclusion and often results in the misinterpretation and/or the discarding of data that does not support the original opinion. Investigators are strongly cautioned to avoid expectation bias through proper use of the scientific method.[ 1]

The question then becomes, what constitutes "all of the relevant data"? Relevant to what? Relevant to a reliable scientific determination, or relevant to the correct law enforcement conclusion? The two are not necessarily the same.

When fire investigators testify as expert witnesses, they are allowed the privilege of expressing an opinion to a jury, as long as that testimony meets these criteria:

(a) the expert's scientific, technical, or other specialized knowledge will help the trier of fact to understand the evidence or to determine a fact in issue;

(b) the testimony is based on sufficient facts or data;

(c) the testimony is the product of reliable principles and methods; and

(d) the expert has reliably applied the principles and methods to the facts of the case.[ 2]

Whether the situation is a proper one for the use of expert testimony is to be determined on the basis of assisting the trier of fact.

"There is no more certain test for determining when experts may be used than the common sense inquiry whether the untrained layman would be qualified to determine intelligently and to the best possible degree the particular issue without enlightenment from those having a specialized understanding of the subject involved in the dispute."[3]

Once he or she has qualified as an expert, and explained fire science to the jury, the members of the jury are likely to perceive anything the investigator says as scientific fact, even when that is not the case. Particularly in a case where there is one individual serving as both the scientist and the law enforcement investigator or case agent, there exists a risk of confusion if the two roles are not distinguished.

A fire investigator's core competency is determining where the fire started. Recent studies have shown that the error rate for this important task may be shockingly high.[ 4] And knowledge that the homeowner was behind on his or her mortgage or recently had an argument with his or her spouse are facts that are not the least bit relevant to the task.

In Michigan Millers Mutual Insurance Corp. v. Benfield, one of the first reliability challenges to a fire investigator serving in the role of the scientist, the Eleventh Circuit Court of Appeals expounded on the special aura of reliability that surrounds "scientific testimony":

The use of "science" to explain how something occurred has the potential to carry great weight with a jury, explaining both why counsel might seek to couch an expert witness's testimony in terms of science, as well as why the trial judge plays an important role as the gate-keeper in monitoring the evidentiary reliability of such testimony. See Daubert, [509 U.S. 579, 590(1993)]. Because of the manner in which this expert's testimony was presented to the jury, we find no error by the trial court in determining Daubert applied to the testimony at issue.[ 5]

The Benfield decision was handed down in May 1998, about a year before the Supreme Court found that Daubert and the Federal Rules of Evidence apply to all expert testimony, not just scientific testimony. In Kumho Tire Co. v. Carmichael, the Supreme Court held that the federal rules did not distinguish between "scientific," "technical," or "other specialized" knowledge.[6 ]Expert testimony is expert testimony, and the court system relies on it in most cases that go to trial today.

Problems can arise when expert testimony is comingled with other investigative information. This problem was recently highlighted in a case decided by the Seventh Circuit Court of Appeals, in which it was argued that a law enforcement officer crossed the line when he attempted to put an "expert gloss" on what would otherwise be admissible fact witness testimony:

"Interpretations" of unambiguous words or phrases that are plainly within the jury's understanding are unlikely to be admissible under Rule 702. Expert testimony does not assist where the jury has no need for an opinion because it easily can be derived from common sense, common experience, the jury's own perceptions, or simple logic.

… The witness's dual role might confuse the jury, or a jury might be smitten by an expert's "aura of special reliability" and therefore give his factual testimony undue weight. Experts famously possess an "aura of special reliability" surrounding their testimony. And it is possible that the glow from this halo may extend to an expert witness's fact testimony as well, swaying the jury by virtue of his perceived expertise rather than the logical force of his testimony. Or, the jury may unduly credit the opinion testimony of an investigating officer based on a perception that the expert was privy to facts about the defendant not presented at trial. Alternatively, the mixture of fact and expert testimony could, under some circumstances, come close to an expert commenting on the ultimate issue in a criminal matter.[ 7]

The court went on to admonish judges to instruct juries about what testimony is expert testimony and what is not, and it further stated that prosecutors should structure their examination of a witness to allow for a separation of …
