I'm just going to point out that your graphic here seems to carry a troubling narrative. Can you clarify why you shared it? Are you supportive of the claim of the text that "0 were white".?
The text description is just for the "unsolved" cases. The race description is for those 16 where they have identified a suspect.
The bigger issue is that there are 146 unsolved mass murder cases, and 130 don't even have the race of the suspect.
