The premise of this chapter is that there are two different how questions to answer regarding an investigation: how was the crime committed? and how can it be solved? A case study is used to illustrate that these how questions are separate issues. The chapter asserts that today’s scientific detection techniques are updated applications of common sense and uses case examples to illustrate both exploratory and inspectional means of identifying how a crime was committed (the commission strategy). The chapter also explores the question of how a crime can be solved (the solution strategy), including allowing the crime’s commission to suggest a solution strategy, using the modus operandi to determine the solution, and considering five factors to determine which solution strategy is most appropriate. The case study of “Thefts from Old Midtown Church” is explored for the factor of how.
