<human>: Background: Liuzzo was born Viola Fauver Gregg on April 1, 1925, in the small town of California, Pennsylvania, the elder daughter of Eva Wilson, a teacher, and Heber Ernest Gregg, a coal miner and World War I veteran. He left school in the eighth grade but taught himself to read. Her mother, Eva Wilson Gregg, had a teaching certificate from the University of Pittsburgh.
Context: After the third march concluded on March 25, Liuzzo, assisted by Leroy Moton, a 19-year-old African American, continued shuttling marchers and volunteers from Montgomery back to Selma in her car. As they were driving along Route 80, a car tried to force them off the road. After dropping passengers in Selma, she and Moton headed back to Montgomery. As they were getting gas at a local filling station, they were subject to abusive calls and racist scorn. When Liuzzo stopped at a red light, a car with four members of the local Ku Klux Klan pulled up alongside her. When they saw a white woman and a black man in a car together, they followed Liuzzo as she tried to outrun them. Overtaking the Oldsmobile, they shot directly at Liuzzo, mortally wounding her twice in the head. The car veered into a ditch, crashing into a fence.  Although Moton was covered with blood, the bullets missed him. He lay motionless when the Klansmen reached the car to check on their victims. After the Klansmen left, Moton began searching for help, and eventually flagged down a truck driven by Rev. Leon Riley. Like Moton and Liuzzo, Riley was shuttling civil rights workers back to Selma.  Liuzzo's funeral was held at Immaculate Heart of Mary Catholic Church on March 30 in Detroit, with many prominent members of both the civil rights movement and government there to pay their respects. Included in this group were Dr. Martin Luther King, Jr.; NAACP executive director Roy Wilkins; Congress on Racial Equality national leader James Farmer; Michigan lieutenant governor William G. Milliken; Teamsters president Jimmy Hoffa; and United Auto Workers president Walter Reuther. She was buried at Holy Sepulchre Cemetery in Southfield, Michigan.  Less than two weeks after her death, a charred cross was found in front of four Detroit homes, including the Liuzzo residence. CANNOTANSWER
