He appears to be African American. He refers to his "momie" as his "step mom" and "2nd mom" in earlier posts.
There isn't anything totally out there on his page, but he comes off as skeevy to me. Nothing that jumps out and says to me, "Wow, of course it was this guy!", but he just seems like a creep with some of his posts/comments. I know Facebook isn't the best place to judge someone's true intelligence, but I wouldn't be surprised if his defense attorney at least tries to keep him from Death Row due to his IQ. He may well be a genius, but he appears to fall far below average to me.
It's also really odd to me that he posted a video in September that supposedly shows animal abuse, and says "This not right." I don't understand how he can be bothered by that, then turn around a few weeks later and do what he did to Zoe.
