I'm coming around to accepting that DW acted alone inside the house. But it's still driving me nuts trying to figure how he got in and out undetected without any help. Even if he was able to walk to and from the Metro unnoticed by someone in the community there are cameras in Metro stations that would have shown him, and someone on one of those trains would have probably recalled seeing him after his picture was all over the news. Also, there are embassies and expensive homes all over that area with security cameras. Something or someone would have detected him. Where did he get the gasoline and duct tape? He couldn't walk around outside carrying a container of gasoline and have no one notice. Who was driving the Porsche, and why steal it just to burn it? Why did he burn his own van and why was it parked downtown? It must have contained evidence of the crime. My guess is that he had it towed to avoid the possibility of being pulled over by police while he was driving and having that evidence seized. Someone must have provided transportation for him either to and/or from that house, probably driving him in his own van. These are questions that keep me up at night. I hate the idea of anyone who helped him commit this horrendous act go unpunished.
