On 22 June 1969, 12 days after her 47th birthday, Deans found Garland dead in the bathroom of their rented house in Cadogan Lane, Belgravia, London. At the inquest, Coroner Gavin Thurston stated that the cause of death was "an incautious self-overdosage" of barbiturates; her blood contained the equivalent of ten Seconal capsules. Thurston stressed that the overdose had been unintentional and no evidence suggested that she had died by suicide. Garland's autopsy showed no inflammation of her stomach lining and no drug residue in her stomach, which indicated that the drug had been ingested over a long period of time, rather than in a single dose. Her death certificate stated that her death was "accidental". Supporting the accidental cause, Garland's physician noted that a prescription of 25 barbiturate pills was found by her bedside half-empty and another bottle of 100 barbiturate pills was still unopened.
