A young black man who was accused of raping a pregnant white woman and subsequently thrown in jail in Mississippi to await trial. However, a band of angry white men kidnapped him before his trial and killed him. Despite the fact that some of the murderers confessed, the entire group of killers was released without an indictment by the Mississippi state jury. This event took place in 1959 and is what encourages Griffin to travel from New Orleans to Mississippi. Wanting to gain firsthand insight into what it’s like to exist as a black man in what people considered at the time to be the most racist state in the South, he takes a bus that passes through Poplarville, the town in which Mack Parker was killed.
