He looks like anyone else that has been accused of being a serial killer. I have read all the pages in the Heuermann threads where people comment what an ogre he is, how scary he looks, how he would look killing the women, etc. He doesn't look scary. He's just tall and heavy set. He doesn't walk weirdly. There was nothing odd about him in the interview with the WEIRDO French guy. There was nothing odd about him in the recorded phone call to whatever her name is.
And Costello's pimp who claimed to have seen his car is lying. Watch the old documentaries, read the old articles about LISK. Not once did he mention a car. Then all of a sudden, 13 years later, a pickup truck appears. Hell, they didn't even report Costello missing back when she was murdered.
8TB might seem like much, but it isn't really. Michael Brown will crush this case easily, just wait and see.
I suspect the real reason for his burner phones is because he has been with prostitutes and wants to keep it a secret from his wife. Some of his search history is pervy but him Googling the Long Island murders and serial killers 200 times is just a pudgy guy being interested in serial murders, especially close to home. Maybe he's a websleuth?
