"20/20? takes you inside one of the most controversial bullying cases of our time: the killing of California eighth-grader Larry King by classmate Brandon McInerney.

In February 2008 McInerney brought a gun to school and shot King in front of their English class. Why? The show examines all sides of this question. But it starts with this: Larry was different. He was exploring his sexuality, sometimes wearing make-up and girls' clothing.

Here's a preview:

The band Residual Kid celebrates differences in its song, "Can't Take Me Away," which will be featured in the show.
