Question

Investigating arson can be a very complicated and complex job, as you learned in the unit! It is also generally a time sensitive matter. Forensic scientists who investigate arson must not only act quickly, but also methodically.
In order to practice how you would respond during an arson investigation, you will be creating a ‘game plan’ or ‘fire investigation timeline’ for what you would do upon arriving at the scene of a fire. Using what you learned in the unit as well as any necessary online research, you will articulate each step that would take place during your investigation. Be sure to number your steps and keep in mind any unexpected situations that might occur.

For example: “First, I would want to find the fire’s origin and look for signs of accelerant use. If I was able to locate the origin, I would do my best to preserve the area. If not, …”

Your ‘timeline’ should be detailed but it does not need to be as extensive as a research paper or essay. You can format your timeline however you like – as an actual timeline, a bulleted list, or short paragraphs as long as you include a clear format like first, second, third, etc. Be sure to include at least six steps.

You can create your ‘timeline’ in a word processing program or a slide presentation. You will be graded on the accuracy of your timeline as well as mechanics and grammar. For more details, see the rubric below.

The Plot Explodes (ongoing activity)
An explosion has occurred in a house down the street from Dr. Fisher’s apartment! Fortunately, the fire was controlled before it could spread to the rest of the block. No one was in the house when the blast occurred. All personal possessions in the house, including a computer and several filing cabinets, have been destroyed.

Property records show that Dr. Fisher’s former patient, Bill, bought the house a year ago. He was still Dr. Fisher’s patient at that time. Apparently, their relationship was strained. Bill had tried to sue Dr. Fisher for malpractice, without success.

When investigators searched the scene, they found bomb fragments with homemade electronics. They traced the electronics to a nearby store where Bill is a customer. They also found a metal cabinet at the scene that survived the blast. Inside the cabinet were several boxes of .38 caliber brass bullets.

So far, investigators have been unable to locate Bill for questioning.

Who do you think bombed Bill’s house, and why? (one to two sentences)
What other types of explosion or fire evidence might you look for within the blast radius? (two to three sentences)
Does this incident change your theory on Dr. Fisher’s murder? Explain. (three to five sentences)

Answer 1

Answer:

First, I would want to find what started the fire and why that's what caused it.

Second, I would take pictures of the area where the fire started if found.

Third, I would interview the witnesses.

Fourth, I would document the scene and write down everything that I see and what the people seen/heard happen.

Fifth, They need to do a full scene investigation.

Sixth, They need to do a follow up investigation.  

Who do you think bombed Bill’s house, and why? (one to two sentences) I think Bill bombed his own house because he did not want to be caught. He most likely bombed his house with all his belongings so that he couldn't be traced.

What other types of explosion or fire evidence might you look for within the blast radius? (two to three sentences) Within the blast radius I would search for chemical residue. I would try to find Bill as soon as possible to match the chemical residue on his clothes if there is any.

Does this incident change your theory on Dr. Fisher’s murder? Explain. (three to five sentences) As sad as it is I believe that Dr. Fisher was murdered by his own patient Bill since they had a very hostile relationship. The incident of Bill’s house bombing doesn’t change my theory on Dr. Fisher’s murder, in fact, it further consolidates my theory of Bill being the murderer since Bill wanted to get rid of the evidence so that’s why he bombed his own house.
