Investigation involves which activity?

• A. Filing charges
• B. Enforcing sentences
• C. Preparing PSI
• D. Collecting fines

Answer: (C)

In this context, investigation refers to gathering information used to help determine a sentence. The presentence investigation (PSI) is prepared to aid the judge by compiling details about the offender—criminal history, personal background, employment, family situation, substance use, mental health, and the impact of the offense on victims. A probation officer typically conducts interviews, reviews records, and may coordinate with treatment providers to build a comprehensive picture. The resulting PSI informs sentencing decisions, including probation conditions, treatment needs, supervision level, and restitution.

Filing charges is a prosecutorial step that occurs before trial, not an investigative activity used for sentencing. Enforcing sentences is a corrections function that happens after sentencing, ensuring compliance with the court’s orders. Collecting fines is a post-sentencing financial task, not part of the investigative information-gathering used to determine appropriate punishment.
