Ronnie Van Zant was killed by blunt head trauma. He had about a quarter sized bruise on his right temple. This occurred in the October 20, 1977 plane crash.
In the year leading up to Vincent Van Gogh's death (1890), he had fits of despair and hallucinations. On July 27, 1890, Van Gogh shot himself in the chest with a revolver. The bullet passed through his chest without doing major damage to his internal organs. Van Gogh was rushed to the hospital and died the next day of an untreated infection. His death is generally accepted as a suicide.
