Donald Teare, a forensic scientist, recommended by Scotland Yard, who had overseen over 1,000 autopsies, was assigned to the Lee case. His conclusion was "death by misadventure" caused by cerebral edema due to a reaction to compounds present in the combination medication Equagesic. Although there was initial speculation that cannabis found in Lee's stomach may have contributed to his death, Teare said it would "be both 'irresponsible and irrational' to say that might have triggered either the events of Bruce's collapse on May 10 or his death on July 20". Dr. R. R. Lycette, the clinical pathologist at Queen Elizabeth Hospital, reported at the coroner hearing that the death could not have been caused by cannabis.
