““from the Adairsville PD. What you’ve got to do is imply that you understand the subject, understand what was going through his mind and the stresses he was under. No matter how disgusting it feels to you, you’re going to have to project the blame onto the victim. Imply that she seduced him. Ask if she led him on, if she turned on him, if she threatened him with blackmail. Give him a face-saving scenario. Give him a way of explaining his actions. The other thing I knew from all the cases I’d seen is that in blunt-force-trauma or knife homicides, it’s difficult for the attacker to avoid getting at least traces of the victim’s blood on him. It’s common enough that you can use it. When he starts to waffle, even slightly, I said, look him straight in the eye and tell him the most disturbing part of the whole case is the known fact that he got Mary’s blood on him. “We know you got blood on you, Gene; on your hands, on your clothing. The question for us isn’t ‘Did you do it?’ We know you did. The question is ‘Why?’ We think we know why and we understand. All you have to do is tell us if we’re right.” And that was exactly how it went down. They bring Devier in. He looks instantly at the rock, starts perspiring and breathing heavily. His body language is completely different from the previous interviews: tentative, defensive. The interrogators project blame and responsibility onto the girl, and when he looks as if he’s going with it, they bring up the blood. This really upsets him. You can often tell you’ve got the right guy if he shuts up and starts listening intently as you speak.””
