No. Politely decline and ask for an attorney. New Mexico State Police, APD, sheriffs, and city police use trained interrogation. Anything you say is admissible. Invoke your Fifth Amendment right to silence and N.M. Const. Art. II, § 15 right against self-incrimination.

Yes. New Mexico misdemeanors carry up to 1 year jail; petty misdemeanors up to 6 months. Pretrial Diversion through DA offices can result in dismissal. DV and DWI convictions trigger major collateral consequences.

State cases go through New Mexico District Court (felonies) or Magistrate / Metropolitan Court (misdemeanors). Federal cases go to U.S. District Court for the District of New Mexico (Albuquerque, Santa Fe, Las Cruces, Roswell) under the U.S. Sentencing Guidelines. Federal cases commonly involve border-zone drug trafficking, illegal reentry (8 U.S.C. § 1326), Major Crimes Act offenses on Native lands (substantial volume given numerous reservations), and § 922(g) firearm cases.

New Mexico plea agreements under NMRA 5-304 are negotiated between the District Attorney and defense. Pleas can include charge reductions, Pretrial Diversion (NMSA § 31-16A-1), Conditional Discharge (§ 31-20-13 for first-time drug), deferred sentence (§ 31-20-9), drug court entry, and stipulated sentence recommendations.

Yes — the Criminal Record Expungement Act of 2019 (NMSA § 29-3A-1 et seq.) is a new and relatively broad framework. Most misdemeanors expungeable after 2 years; most fourth-degree felonies after 6 years; third-degree after 8; second-degree after 10; first-degree generally not eligible. Sex offenses, DV, DWI excluded. Marijuana convictions subject to automatic expungement under the Cannabis Regulation Act.

New Mexico handles juveniles under 18 in juvenile court under NMSA § 32A. Juvenile records are confidential and sealable under § 32A-2-26. Serious youthful offender designation for 14-17 allows adult-style sentences in juvenile system. Youthful offender (14-17 charged with certain serious offenses) — judicial transfer required.

New Mexico DWI under NMSA § 66-8-102 uses .08 BAC (.04 commercial, .02 under-21). Aggravated DWI (.16+, refusal, accident with injury) carries enhanced penalties. Implied consent under § 66-8-107 — refusal triggers 1-year administrative license suspension. Mandatory IID for all DWI convictions under § 66-8-102. Fourth DWI is a felony.

New Mexico grades felonies as First-Degree (life or capital — death penalty abolished 2009; sentence is life imprisonment), Second-Degree (9-15 years), Third-Degree (3-6 years), Fourth-Degree (18 months) under NMSA § 31-18-15. Murder First-Degree carries life imprisonment (no parole eligibility until 30 years). New Mexico uses determinate sentencing — sentences are fixed and reduced only by limited good-time credits. Habitual Offender enhancement under NMSA § 31-18-17 dramatically increases sentences — one prior felony adds 1 year, two add 4 years, three add 8 years. New Mexico legalized recreational marijuana in 2021 (Cannabis Regulation Act, NMSA § 26-2C-1 et seq., effective June 2021 with retail sales April 2022) — adults 21+ can possess up to 2 oz cannabis flower; medical cannabis since 2007. The Cannabis Regulation Act also provided for automatic expungement of many prior marijuana convictions. New Mexico has deferred sentencing under NMSA § 31-20-9 — court can defer entry of judgment, resulting in dismissal upon successful probation. New Mexico’s expungement statute under NMSA § 29-3A-1 et seq. (Criminal Record Expungement Act of 2019) provides petition-based relief for most misdemeanors after 2 years and many felonies after 6-10 years. New Mexico District Attorneys plea-bargain extensively.
