Arson & Explosions

What can assist in arson? How do we analyze an explosion?

Page 16: Deardorff 20 For 20

Firearms, Tool Marks & Impressions

A lot of comparisons go into the anaylaysis of these.

Page 17: Deardorff 20 For 20

Document & Voice Analysis

These are tools used for comparison.

Page 18: Deardorff 20 For 20

Case Analysis

Each of you will do a case analysis of a different case.

Page 19: Deardorff 20 For 20

True Crime Readings Each of you will read a true crime

novel and present to the class.
