Story Idea for Forensics

The four areas of forensic analysis are:
1. DNA isolation and fingerprinting
2. blood components – centrifuge separation and tissue analysis
3. chromatography – liquid and paper
4. mechanical separation – solvent extraction and filtration

You have arrived at a murder scene and found the following evidence: blood splatters on the victim and door handles, a bullet lodged into a desk, and fingerprints on wine glasses. Describe the methods you would use along with the reasons why you chose to use these methods of analysis in your presentation. Describe how these methods would be used to convict the murderer.

You have arrived at the scene of a burglary and have found the following: a mixture of a unique oil in water, paint chips found mixed with dirt and soil in a foot print, and a fluid sample that looks like saliva (with cells). First describe the methods used to separate and isolate each piece of evidence, then describe how you would use this evidence to convict the burglar.

You have arrived at the scene of an arson attack at a department store and find the following evidence: an accelerant (i.e. gas) mixed with oil, water, and dirt (a suspension), fibers torn from a jacket at the building exit, and ink spots on a pipe. Describe how to isolate and identify the accelerant from the other parts of the suspension. Include a brief outline of the steps used in separating each part and how you would use this evidence.

Remember to include diagrams or other images in your report and presentation to the court. In addition, include a glossary of new terms used with an explanation of how they relate to the methods used and the evidence gathered.
