Mr. John Diggs-Dorsey, a Black man in his early twenties, lived and worked in Darnestown as a servant to James and Linnie Tschiffely, On July 25, 1880, Linnie Tschiffely accused Diggs-Dorsey of rape and physical assault, a charge he denied, After a two-day manhunt, Diggs-Dorsey was brought to the county jail in Rockville, the present day location of the County Council Building. On July 27, a lynch mob kidnapped him, marched him in leg-irons for one mile, and hanged him on Route 28.
