Key Takeaways
  • Idaho felony structure: punishment range within EACH individual statute (NOT tiered classification grid like KS); "unified sentence" = fixed minimum (mandatory before parole eligibility) + indeterminate maximum; Idaho Commission of Pardons and Parole controls actual release. Key felonies: murder 1st = death or life; murder 2nd = up to life; rape = 1yr-life; robbery = up to 25yr; burglary = up to 15yr; grand theft (>$1K) = up to 14yr. Idaho death penalty: lethal injection; active death row at IMSI (Kuna, Ada County). NO decriminalization of any drug in Idaho (even small marijuana possession = misdemeanor; compare OR/WA/NV legal marijuana; MT neighboring state legal). Ada County (4th Judicial) = highest-volume felony docket; Ada County DA + Ada County Public Defender.
  • Idaho meth crisis: I-84 corridor (Portland/Salem/Eugene OR → Boise → Salt Lake City UT) = primary Pacific Northwest/Intermountain meth distribution route; Sinaloa/CJNG cartel supply; DEA Boise District + Idaho Meth Project. Drug trafficking mandatory minimums § 37-2732B: 28+ grams heroin/fentanyl or 100+ grams meth or 2+ lbs marijuana = 3yr mandatory min; larger quantities = 5yr or 10yr mandatory; NO safety valve for first-time offenders (unlike federal law). IDOC: IMSI (Kuna; death row) + South Idaho CI (Boise) + ISCI (Boise) + Idaho Correctional Center (Kuna; former CoreCivic contract). Drug courts § 19-5602: Ada/Canyon/Twin Falls/Bonneville counties; structured supervision + testing + treatment + accountability hearings; charge dismissal/sentence reduction on successful completion.
  • D. Idaho (550 W. Fort St, Boise): drug trafficking I-84 + federal land crimes + immigration + financial crimes + Indian Country (Major Crimes Act § 1153). Fort Hall (Shoshone-Bannock): tribal court for lesser offenses (ICRA 3yr max; VAWA enhanced up to 9yr); Major Crimes Act felonies = D. Idaho U.S. Attorney prosecution. Idaho Panhandle extremist history: Aryan Nations (Hayden Lake/Kootenai County) dissolved after SPLC lawsuit Keenan v. Aryan Nations (2000) + compound seizure; FBI monitors ongoing right-wing extremist activity. Idaho public land crimes: illegal cartel marijuana grows on national forests + illegal hunting/wildlife violations + timber theft + arson → D. Idaho prosecution; Idaho F&G + U.S. Fish and Wildlife collaboration. Juvenile justice: IDJC (§§ 20-501); Ada County + Canyon County juvenile courts; IDJC correction facilities + community supervision.

Idaho criminal law is codified in the Idaho Criminal Code (Idaho Code §§ 18-101 et seq.) — a comprehensive statutory framework defining felonies and misdemeanors with specific penalty ranges. Idaho uses a category-based felony classification: felonies are punishable by imprisonment in the state penitentiary (Idaho Code § 18-105), while misdemeanors are punishable by imprisonment in the county jail. Idaho does not use a numbered felony severity grid like Kansas (which uses Severity Levels 1-10) or a lettered classification like Arkansas (Classes A through Y). Instead, Idaho specifies the penalty range within each individual crime's statute — for example, first degree murder is punishable by death or life imprisonment; robbery is punishable by up to 25 years; grand theft is 1-14 years. Idaho retained the death penalty and has carried out executions — Idaho uses lethal injection and has a functioning death row at the Idaho Maximum Security Institution (IMSI) in Kuna (Ada County).

Boise's rapid growth has strained Idaho's criminal justice system. Ada County's population growth (Boise, Meridian, Eagle, Kuna, Star) has increased crime in raw numbers even as the crime rate per capita remains lower than many major metros. The most significant criminal justice challenge in Idaho is the state's methamphetamine crisis — I-84 from Oregon through Boise to Utah is a meth distribution corridor, and Idaho has some of the highest meth manufacturing and trafficking rates relative to its population in the western United States. Boise's proximity to Oregon (where some drug possession was decriminalized by Measure 110 — later modified — and where marijuana is legal) creates cross-border drug issues. The Idaho Department of Correction (IDOC) oversees Idaho's prison system, with facilities including the IMSI, South Idaho Correctional Institution (Boise), and the Idaho Correctional Center (near Boise, previously operated by CCA/CoreCivic).
