For this assignment, you will be putting together what you know so far about the evidence collected after Geoffrey Popovich’s death:

Evidence #1: Sample collected from Popovich’s skull.

Evidence #2: Sample collected from Popovich’s tent.

Evidence #3: Sample collected from beneath Popovich’s fingernails.

Evidence #4: Sample taken from Popovich’s clothes.

• Evidence #5: Popovich’s boxers.
• Evidence #6: Popovich’s pants.
• Evidence #7: Popovich’s shirt.
• Evidence #8: Bottle found next to Popovich’s body.
• Evidence #9: Rock found next to Popovich’s body.
• Evidence #10: Towel taken from Wilson Daniels’ car.
• When completing your evidence analysis, you will need to refer back to:
• Hair Evidence
• UV Light Evidence
• Kastle-Meyer Blood Evidence

DNA Evidence

Assignment Requirements

• What species did you identify Evidence #1 to be from? Use at least one structural/anatomical feature, and describe how you came to this conclusion. You may wish to revisit the trace evidence lesson to review hair structure/anatomy.

What species did you identify Evidence #2 to be from? Use at least one structural/anatomical feature, and describe how you came to this conclusion. 

• What species did you identify Evidence #3 to be from? Use at least one structural/anatomical feature, and describe how you came to this conclusion. 

What species did you identify Evidence #4 to be from? Use at least one structural/anatomical feature, and describe how you came to this conclusion. 

• Based on the UV light test, which pieces of evidence contain body fluids? How did you reach this conclusion?

Based on the Kastle-Meyer Blood tests, which pieces of evidence contain blood? How did you reach this conclusion? Why were the positive and negative controls included?

• Looking at the results of the DNA electrophoresis:

Do any of the lanes match? Which ones?

Explain why these lanes match. Use the following terms for full credit: restriction enzyme, fragment, and positive charge.

Based on your evidence analysis, who is your prime suspect? Is this the same prime suspect that you had last week? Which pieces of physical evidence support your hypothesis for who the prime suspect is? Does any of this evidence refute this?

1. Submission Guidelines

You will need to upload a .pdf with your responses to all questions.  I would recommend using a word processor (such as Microsoft Word) or using Google Docs.
