Presentence investigation report

A presentence investigation report (PSIR) is a legal term referring to the investigation into the history of person convicted of a crime before sentencing to determine if there are extenuating circumstances which should ameliorate the sentence or a history of criminal behavior to increase the harshness of the sentence. The PSIR has been said to fulfill a number of purposes, including serving as a charging document and exhibit proving criminal conduct, and is said to be akin to a magistrate judge's report and recommendation.
