What happened at the Sojourner Truth Housing Project prior to June 20th?

Explanation:

The 1943 Detroit race riot took place in Detroit, Michigan, of the United States, from the evening of June 20 through the early morning of June 22. It occurred in a period of dramatic population increase and social tensions associated with the military buildup of U.S. participation in World War II, as Detroit's automotive industry was converted to the war effort. Existing social tensions and housing shortages were exacerbated by racist white feelings about the arrival of nearly 400,000 migrants, both African-American and White Southerners, from the Southeastern United States between 1941 and 1943. The new migrants competed for space and jobs, as well as against European immigrants and their descendants.
