I think that one part of your announcement would focus on the manner of death. Part of Malcolm X's legacy is that his death was in a flurry of bullets from the guns of assassins. From this point, I think that being able to trace the arc of his life might also be good to include in an article where Malcolm's death is being detailed. His life as a petty criminal and his conversion to Islam in jail can be complemented with his rise in the ranks in the Nation of Islam and his emergence as a voice in the Civil Rights Movement. Addressing his voice in the Civil Rights dialogue with leaders like Dr. King is also significant in talking about his life's work.
Part of a newspaper article in announcing Malcolm X's death would have to include his break with the Nation of Islam. It is significant because Malcolm X sought a new approach to that which was so closely identified with him. Of his many quotes, I think that his understanding of how White Americans do in fact have a role in Civil Rights is significant: “In the past I have made sweeping indictments of all white people. I will never be guilty of that again.” This quote would be important to include in a newspaper article announcing Malcolm X's death because it is a testament to the complexity of the Civil Rights Movement, an intricacy with which Malcolm X will always be associated.
