The shootings took place on May 4, 1970, during a rally opposing the expanding involvement of the Vietnam War into Cambodia by United States military forces, as well as protesting the National Guard presence on campus and the draft. Twenty-eight National Guard soldiers fired about 67 rounds over 13 seconds, killing four students and wounding nine others, one of whom sustained permanent paralysis.

Eight of the shooters were charged with depriving the students of their civil rights, but were acquitted in a bench trial.
