The Nevada Division of Parole and Probation (NPP) Presentence Investigation Specialists conduct detailed investigations of persons convicted of felony or gross misdemeanor offenses and make sentencing recommendations to the District Court Judges through a document called a Presentence Investigation Report. The reports detail crimes that vary from the most serious offenses that include murder, sex offenses, crimes against children, to the less serious offenses that include theft and substance abuse. The investigation and report content requirements are governed by NRS 176.135 thru 176.156. In certain instances a person cannot receive a suspended sentence/probation without having an investigation completed and delivered.
