] Lee's passing. Chow appeared on television to try to
] settle the public furor that quickly developed. He
] explained what happened, omitting only the fact that Lee
] had not died at home. The press soon uncovered the truth,
] however, and demanded to know what Chow was trying to
] cover up. R.D. Teare, a professor of forensic medicine at
] the University of London who had overseen more than
] 90,000 autopsies, was called in and declared that it was
] basically impossible for the cannabis to be a factor in
] Lee's death. In Teare's opinion, the edema was caused by
] hypersensitivity to either meprobamate or aspirin, or a
] combination of both. His view was accepted by
] authorities, and a determination of "misadventure" was
] stamped on Lee's death.
