Executive summary

The official, legal conclusion reached after investigation and a coroner’s inquest was that Robert Maxwell died of a heart attack combined with accidental drowning, with the December 1991 inquest recording that verdict despite unresolved medical disagreement among pathologists [1] [2]. Earlier provisional autopsy findings and judicial statements described natural causes before a fall overboard, and Spanish authorities reported no obvious signs of violence when his unclothed body was recovered [3] [4].

1. The formal ruling: heart attack plus accidental drowning

At the coroner’s inquest in December 1991 the official verdict recorded Maxwell’s death as the result of a heart attack combined with accidental drowning, a conclusion repeated in multiple summaries of the inquiry and contemporary reporting [1] [2]. That formal finding is the legal endpoint often cited in biographical and encyclopedic accounts of Maxwell’s death [1] [5].

2. Autopsies, medical disagreement and provisional findings

Medical examinations produced nuance and disagreement: Spanish officials first reported that a provisional autopsy indicated Maxwell died of natural causes before falling into the sea and that the death “wasn’t death by drowning” according to a judge’s statement [3]. A later autopsy report released to the press said he “apparently did not die of drowning but probably suffered a heart attack,” even though the forensic pathologist acknowledged there was no direct anatomical evidence of an acute heart attack and three pathologists at the inquest could not agree on a single cause [6] [1].

3. The scene and immediate facts investigators relied on

Maxwell disappeared from his yacht, the Lady Ghislaine, and his body was recovered floating offshore, unclothed and showing no clear signs of violence, facts reported by Spanish rescue services and contemporaneous newspapers and later repeated in investigative summaries [4] [7]. The absence of obvious wounds, save for a minor graze, and evidence of serious pre‑existing heart and lung disease were part of the medical record considered during the inquiry [1].

4. Why doubts and alternate theories persisted

Despite the official ruling, doubts proliferated because the autopsies were inconclusive, because Maxwell’s sudden disappearance fitted several narrative possibilities (accident, suicide, or homicide), and because his global business empire collapsed immediately afterward amid revelations of massive pension‑fund misappropriation — circumstances that fed speculation about motive and cover‑ups [6] [8]. Authors and investigative accounts have pushed alternative explanations, including allegations of Mossad involvement or other foul play, but such claims remain contested and not part of the official findings [9].

5. The inquiry’s limits and the public fallout

The coroner’s determination of accidental death answered the narrow legal question of cause, but it did not settle wider questions about motive, responsibility or the precise sequence of events leading to Maxwell’s fall, and reporting and later books make clear the inquest’s medical disagreements left space for competing narratives [1] [6]. What the inquiry did trigger beyond the verdict was a forensic unravelling of Maxwell’s finances — the discovery of a huge pension‑fund shortfall and misappropriation — which reshaped public memory of his death and prompted many to reassess whether the official account was sufficient [8] [6].

6. Bottom line: the official answer and what it covers

Officially, following autopsies, judicial statements and the December 1991 inquest, Maxwell’s death is recorded as caused by a heart attack together with accidental drowning; that is the formal conclusion reached by the legal process even though medical experts at the inquest did not unanimously agree and significant uncertainty persists in the public record [1] [6]. Assertions that he was murdered or intentionally took his own life remain outside the legal finding and are treated as speculative in mainstream accounts, though they continue to be argued in books and reportage [9] [10].
