Physical evidence can help establish a suspect's MO.

• A. MO is irrelevant to physical evidence.
• B. Physical evidence can help establish a suspect's MO.
• C. MO relates only to motive.
• D. MO is only used in narcotics cases.

Answer: (B)

Modus operandi is the pattern a criminal uses to commit offenses—the usual methods, tools, and sequence of actions they follow. Physical evidence at a scene often captures those exact elements: the specific tool left behind, how the entry was made, the order of steps taken, and even particular routines or preferences. When investigators find similar details across different incidents, they can see a consistent way the offender operates, which helps connect crimes to the same person and build a case around that pattern. So physical evidence can indeed help establish a suspect's MO because it reveals the habitual, repeatable actions the criminal uses. Keep in mind that MO isn’t about motive. It’s about the how—the technique and process—whereas motive explains why the crime happened. And MO isn’t limited to narcotics cases; it applies to burglary, theft, homicide, and many other offenses as well.
