Enable an AI agent to recognise, document and assess a reported death by hanging while distinguishing evidence, intent, responsibility and unresolved circumstances.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an AI agent to recognise, document and assess a reported death by hanging while distinguishing evidence, intent, responsibility and unresolved circumstances.
Hanging to death is a fatal event in which a ligature tightened around the neck by the weight of all or part of the body causes death through compression of neck structures.
It can be Classify a report as a candidate fatal hanging event and identify missing evidence.; Separate observations from claims about cause, intent, responsibility and authority.; Link the event to related death records, investigations and judicial proceedings.; Compare conflicting accounts while preserving their sources and assessment dates.; Flag a potentially ongoing emergency when death has not been established and direct the agent toward emergency assistance.; Produce a non-graphic case summary that states unresolved findings and limits unnecessary personal disclosure..
Distinguishing features
The reported event involves neck compression associated with suspension and body weight; neck compression alone does not establish hanging.
Death must be established and causally connected to hanging; survival or an unknown outcome does not establish hanging to death.
A suspended body does not by itself establish that hanging caused death; postmortem suspension must remain a distinct possibility when supported by case uncertainty.
The physical event does not by itself establish suicide, homicide, accident or execution; each interpretation requires separate evidence.
A sentence of death by hanging, a threat or a representation of hanging is not evidence that a fatal event occurred.
Scope
+ Identification of a reported hanging event and its fatal outcome
+ Evidence connecting hanging with death, including uncertainty about causation
+ Distinction between physical circumstances, intent and official manner-of-death classification
+ Participants, attributed actions and any asserted institutional authority
+ Case interpretation, sensitive documentation and appropriate referral
- Instructions, equipment specifications or calculations for carrying out hanging
- Nonfatal hanging as a clinical event, except to establish the fatal-outcome boundary
- General models of suicide, homicide, accidents and capital punishment
- Detailed medical treatment and forensic examination protocols
- Ligatures, suspension structures and other physical objects as independently modelled things
Characteristics
- Event actuality
- reported occurrence | corroborated occurrence | disputed occurrence | threatened or planned only | representation only Separates an actual fatal event from intentions, orders and depictions.
- Hanging attribution
- reported | supported by documented assessment | disputed | undetermined Prevents a scene description or label from being treated as an established mechanism.
- Fatal outcome
- death documented | death reported but unverified | survived | outcome unknown Determines whether the event satisfies the fatal scope.
- Causal relationship to death
- source-attributed relationship between the hanging event and death, with assessment status Distinguishes death caused by hanging from suspension associated with a death for another reason.
- Manner-of-death assessment
- source wording and local classification, with issuing authority and date Preserves jurisdiction-specific classifications without inferring intent from physical circumstances.
- Attributed participant role
- deceased person | alleged actor | witness | responding professional | investigating authority | authorising institution Separates involvement, testimony and alleged responsibility.
- Execution context
- institutional execution asserted | institutional execution documented | not asserted | disputed | unknown Identifies the execution sense without treating asserted authority as proof of legality.
- Event and death chronology
- documented dates or timestamps with precision and uncertainty; elapsed time only when supported Allows delayed death to be considered without assuming it occurred at the scene.

Fatal hanging boundary Establishes what the registry label denotes and whether a reported event belongs within it.
Hanging, fatal hanging, execution orders and suspended remains can be conflated.
Registry sense
Resolves the meaning of the registered name without creating additional registry entries.
Fatal event or execution sense
Record whether registry provenance supports all fatal hanging events or specifically execution by hanging.
- Does the originating registry concept denote death by hanging generally or execution by hanging specifically? definition
- Which originating identifier, description or mapping supports that interpretation? provenance
Event membership
Tests occurrence, hanging attribution and fatal outcome separately.
Occurrence and fatality
Treat event occurrence, death and their causal connection as separately supportable claims.
- What evidence establishes that hanging occurred and that the person died? provenance
- Is this a fatal event, a nonfatal event, an unverified report, or only a sentence, threat or depiction? boundary
Death and causal evidence Organises evidence about whether hanging caused the documented death.
Neither a suspended body nor a death certificate label should erase uncertainty or conflicting assessments.
Causal assessment
Preserves qualified assessments and alternatives without reproducing examination procedures.
Hanging as cause
Record the attributed cause of death, its evidentiary basis and any unresolved alternative explanation.
- Which qualified assessment connects hanging to death, and how certain is its conclusion? provenance
- Does the evidence distinguish fatal hanging from another cause of death followed by suspension? boundary
Fatal outcome chronology
Relates the event, discovery and documented death without assuming simultaneity.
Event-to-death sequence
Preserve documented timing and any interval of survival relevant to causal attribution.
- What times are documented for the event, discovery and death, and with what precision? measurement
- If death occurred later, what assessment attributes it to the hanging event? provenance
Intent, responsibility and authority Separates the physical event from conclusions about agency and institutional context.
The same event label can appear in accounts of suicide, homicide, accident or execution without establishing any of those classifications.
Agency and manner
Records attributed actions, intent and manner-of-death assessments as distinct claims.
Attributed agency
Preserve who is said to have acted and who assigned the event's classification.
- What evidence supports each attribution of self-directed action, another person's involvement or accidental circumstances? provenance
- Which authority assigned the manner-of-death classification, using which terminology, and is it disputed? definition
Execution context
Captures asserted institutional authorisation and actual occurrence separately.
Authority and completion
Link any execution claim to its institution, proceeding and evidence of the death, while keeping legal appraisal distinct.
- Which institution or proceeding is cited as authorising this hanging, and what record supports that claim? provenance
- Does the record establish a completed execution or only a sentence, scheduled event or disputed allegation? boundary
Case record and agent action Guides evidence reconciliation and appropriate handling of fatal or potentially ongoing hanging reports.
An agent must avoid turning uncertain reports into settled deaths or producing unnecessary graphic and operational detail.
Account reconciliation
Maintains traceable differences among scene reports, medical conclusions and institutional accounts.
Conflicting death accounts
Attach each consequential claim to its source and preserve revisions rather than silently resolving disagreement.
- Where do the available accounts disagree about hanging, fatality, causation or responsibility? provenance
- What additional record or qualified review could resolve each disagreement? action
Response and disclosure
Distinguishes retrospective documentation from reports that may require immediate assistance.
Appropriate case handling
Use the person's known status and the task's purpose to guide escalation and proportionate disclosure.
- Could this report concern a person who is still alive or in immediate danger, requiring emergency assistance? action
- Which details are necessary for the authorised task, and which graphic, operational or identifying details can be omitted? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Hanging - Hanging describes the mechanism and can be survived; hanging to death requires a fatal outcome.
- Ligature strangulation - In forensic usage, ligature strangulation involves tightening by a force other than body weight; hanging involves body weight.
- Manual strangulation - External neck compression is applied directly by hands rather than by a body-weight-tightened ligature.
- Capital punishment - Capital punishment is a legal sanction that may use various methods; hanging deaths also occur outside judicial execution.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of hanging to death this model covers, and on what evidence? provenance
What the second pass must settle
- Does the originating registry identifier restrict this entry to execution by hanging, despite the broader English label?
- Does an existing Vercy world model already own this concept, requiring a registry link instead of a separate publication?
- Which authoritative sources should define the hanging boundary and the evidence required for causal attribution?
- How should differing local manner-of-death classifications, particularly those involving institutional executions, be represented without false equivalence?
- What evidence standard should govern inclusion of delayed deaths and historical reports with incomplete or conflicting records?
