Jackson State College was a historically Black university in Jackson, Mississippi — established in 1877, one of the oldest HBCUs in the country. In May 1970, students were protesting both the U.S. invasion of Cambodia and the killings at Kent State ten days earlier. There had been unrest on Lynch Street, the main road running through campus, over several nights preceding the shooting.
On the night of May 14–15, Mississippi Highway Patrol officers and Jackson city police responded to reports of disorder. At approximately 12:05 a.m. on May 15, without any clear command to fire and without issuing a dispersal order, the officers opened fire on Alexander Hall, a women's dormitory where students had gathered. According to the President's Commission on Campus Unrest (the Scranton Commission), approximately 460 rounds were fired in approximately 28 seconds. The dormitory's front was riddled with bullet holes.
