Emmett Till was brutally murdered (in the South) after flirting with a white shopkeeper.
He was taken up to the North for an open casket funeral, where there were many photographers and people. The situation gained publicity as many were horrified by the cruel state Emmett was in.
The murderers were tried but not convicted as the jury was all white.
However the situation did bring attention to the extreme racism that was occurring in the South, convincing many people to get involved in the Civil Rights Movement.
