Washington (CNN) -- Ronald Reagan, shot and wounded by John Hinckley Jr., on March 30, 1981, was the ninth American president, in or out of office, to be the target of an assassination attempt since the Civil War. Four presidents were killed.

Will Hinckley go free?

1865: Abraham Lincoln was murdered at Ford's Theatre in Washington by Confederate sympathizer John Wilkes Booth, who was tracked down hiding on a Virginia tobacco farm 12 days later and was shot to death trying to escape. Four co-conspirators, including a woman, were hanged three months later.

1881: James Garfield, only four months in office, was shot at a railway station in Washington by disappointed office-seeker Charles Guiteau. Garfield died 11 weeks later. Guiteau was convicted and hanged within the year.

1901: William McKinley was shot by anarchist Leon Czolgosz at the Pan American Exposition in Buffalo, New York, and died eight days later. Czolgosz was convicted only nine days after McKinley's death and was electrocuted the next month.

1912: Ex-President Theodore Roosevelt, who had succeeded McKinley in office, was making a campaign speech as the Bull Moose Party nominee in Milwaukee, Wisconsin, when he was shot and wounded by a New York saloon keeper, John Schrank, who was committed to a mental institution where he died 30 years later. Teddy Roosevelt finished the speech and lived the rest of his life with the bullet still inside his body.

1933: President-elect Franklin D. Roosevelt survived unscathed when five shots were fired by Guiseppe Zangara in Miami, Florida, but Chicago Mayor Anton Cermak, standing next to Roosevelt, was killed. Zangara pleaded guilty and was electrocuted less than five weeks later. His last words: "Push the button."
