Great story. Even though the premise was revealed you still kept some elements of surprise.
Great narrator. We can see his voice reflect his changes and experience.

His body was burned had and black and the police later called me a monster for it.

Interesting point, revealing the double standards of the time. Black men and women were lynched in the most horrible ways and no white person who participated, even as observer, thought of themselves as such.
The end itself felt like lighting!
