A remarkable memorial opens later this month in Alabama, dedicated to victims of lynching. Oprah Winfrey was given an exclusive tour for "60 Minutes," and The National Memorial for Peace and Justice honors thousands of victims, including one man who was murdered in 1936. 

Lent Shaw was accused of harassing a white woman and lynched when he was 42. The chilling, gruesome image of what happened to him has haunted Shaw's great-grandson, Evan Lewis, nearly his entire life. 

"I knew that he was lynched in Georgia," said Lewis. "I knew that it was a pretty horrific incident and there wasn't a lot said about the history because folks were frankly afraid to speak to it."
