“Body fluids, fibers, gunshot residue, latent prints, deep tissue bruises?” I’m still talking about the ALS and what it might find under different circumstances, and I’m letting him know I understand what it’s like to want what you can’t have.

“Right. Forget it,” he agrees.

“That’s what I recommend. Not that I don’t understand being tempted to try.”

“She’s been in the water,” he says. “A waste of time.”

“And then it has to be explained,” I add. “Everything we do has to be explained.”

“Should I unplug it?” He reaches for the ALS power cord.

“Please,” I reply. “I’m really not interested in putting on goggles and spending an hour scanning the body from head to toe with the Crime-lite just so I can say we did. It might be worth going over her clothing, but that can wait.”

“We don’t know if she had on the clothing when she got these bruises.” Luke returns to that thought as he returns to the table. “Knowing whether she was dressed or not when someone grabbed her upper arms would be an important fact, wouldn’t it? Stripping a prisoner is more about submission than anything else, isn’t it?”

“Depends on who is doing it to whom and why.”

“The logic of torture, a terrible thing to consider, but there is a logic to it. Humiliation, intimidation, controlling your prisoner by stripping him, hooding him. Or her,” he says. “I’m assuming she could have been bound at some point with some type of ligature that was soft and wouldn’t necessarily leave marks on her skin.”

“It’s possible.”

“I imagine him coming up behind her like this.” He holds up his hands to grip imaginary arms, orienting his fingertips and thumbs the way they would be if he grabbed someone by the upper arms from behind. “Maybe to forcibly move her from one place to another, such as if he forced her into a room or dragged her, were she unconscious. Or if she were tied up in a chair and he’s trying to make her give him information so he could steal her identity, for example. Her PIN, her passwords.”

I shine the lamp down her lower legs, brightly illuminating the tops and sides of her ankles and feet, and I find more brownish marks, only these are darker and drier and indistinct in their shape. Picking up the scalpel to make small incisions, I find the darkened areas of skin have lost elasticity, are extremely hard, with no evidence of hemorrhage to the underlying tissue. Not contusions but patterns caused by something else, and I find more of them on the tops of her bare feet and areas of her ankles.

We pull her on her side so I can check her back, and there are two more indistinct hard brown areas on the underside of her right elbow and forearm.
