A complete, journal-grade reference for the forensic-medicine student and the working medico-legal officer: foundations and the medico-legal expert in court, thanatology and the NAME manner-of-death framework, post-mortem changes and time since death estimation, mechanical injuries and the wound-interpretation taxonomy, asphyxial deaths (hanging, strangulation, drowning, chemical asphyxia), thermal and electrical and chemical injuries, firearm and explosive wound interpretation (complementing the forensic-ballistics subject), sexual-offences medico-legal examination (BNS 2023 §§ 63-71 + POCSO + Modified Goa Protocol + Lillu 2013), sudden natural deaths, medical negligence and forensic psychiatry, and the medico-legal autopsy procedure, reporting standards and the death-certification chain.
What forensic medicine actually does inside the criminal-justice system: the history and scope of the discipline, the medico-legal expert's role in court (BSA 2023 § 39 / Daubert / Frye / R v. Turner 1975 admissibility, the Bolam-Bolitho standard), and the ethical frame (Helsinki Declaration, India's NMC Code, AMA, GMC Good Medical Practice).
Start moduleThe conceptual backbone of every medico-legal case: definitions of death (brain death, cardiopulmonary, molecular), the cause / mechanism / manner trichotomy, the NAME five-manner classification (natural, accidental, suicidal, homicidal, undetermined), and the global frameworks (Indian BNSS 2023 inquest, US ME vs Coroner systems, UK Coroner inquest) that decide which deaths require an autopsy.
Start moduleThe continuous biochemical and morphological cascade after death and the methods that read time off it: primary changes (algor / livor / rigor mortis with the Henssge nomogram and Newton's cooling model), decomposition (putrefaction, adipocere, mummification, skeletalisation), and instrumental + biochemical TSD methods (vitreous K+, gastric emptying, supravital reactions, entomology overlap).
Start moduleThe mechanical-injury taxonomy every autopsy report walks through: abrasions, contusions and lacerations with morphology + mechanism + ageing; incised, stab and chop wounds with weapon inference and defence-vs-hesitation patterns; the antemortem vs post-mortem injury distinction; and the simple-vs-grievous-hurt classification under BNS 2023 §§ 114-118 (replacing IPC §§ 319-320) with parallel US ICD and UK ABH/GBH frameworks.
Start moduleThe asphyxial deaths a medico-legal officer reads off the autopsy table every week: hanging and ligature strangulation (groove direction, knot position, Tardieu spots, suicidal vs homicidal differentiation), manual strangulation and smothering (the burking technique, infanticide implications), drowning (wet vs dry, diatom test, vitreous Na+ / K+), and chemical asphyxia (CO + carboxyhaemoglobin, CN + cytochrome oxidase, H2S + sulphhaemoglobin).
Start moduleThe energy-transfer injury classes: burns (degree classification, % BSA via Wallace rule of 9s + Lund-Browder, antemortem-vs-postmortem indicators), electrocution (low-voltage domestic vs high-voltage transmission, Joule burns, lightning Lichtenberg figures), and chemical burns + hypothermia + hyperthermia (acid vs alkali, paraquat ingestion, exposure deaths).
Start moduleThe medico-legal autopsy reading of firearm and explosive injury (complements the forensic-ballistics subject's instrumental side): firearm entry and exit wounds with range-dependent dermal features (contact stellate / near-contact soot / intermediate tattooing / distant impact), atypical firearm wounds (ricochet, intermediate target, bullet embolism, post-mortem firearm-injury distinction), and blast injuries (primary overpressure, secondary fragments, tertiary displacement, quaternary burns + crush).
Start moduleThe medico-legal frame for sexual offences and reproductive criminal cases: sexual-assault examination under BNS 2023 §§ 63-71 + POCSO 2012 + the Modified Goa Medical Protocol (with the Lillu 2013 two-finger-test ban), SAFE-kit evidence collection and chain of custody, pregnancy / delivery / criminal abortion under MTP Act 1971 (amended 2021), and the infanticide vs stillbirth medico-legal distinction (hydrostatic / Ploucquet test).
Start moduleThree high-stakes adjacent areas every medico-legal officer must handle: sudden natural deaths (cardiac via Schwartz 2017 channelopathy classification, SIDS / SUDI, anaphylaxis), medical negligence and the duty of care (Bolam 1957, Bolitho 1997, Jacob Mathew v. State of Punjab 2005, Martin D'Souza 2009, NMC framework), and forensic psychiatry (insanity defence under BNS § 22 vs IPC § 84, McNaughton 1843, Durham 1954, civil + criminal capacity, Selvi v. Karnataka 2010 consent rule).
Start moduleHow a medico-legal case is closed: autopsy procedure (Letulle en masse, Virchow organ-by-organ, Rokitansky in-situ, Ghon thoraco-cervical block) with chain of custody for tissue and toxicology; autopsy reporting standards (WHO, ICAP, NAME US, RCPath UK, NCRB Indian fields); and the death-certification chain (Cause of Death certificate, manner certification, Registration of Births and Deaths Act 1969, INTERPOL DVI medico-legal interface).
