“When she was unconscious,” Cooper said coolly, “some material, probably plastic, was placed around her throat and twisted at the top of the spine.” He tilted her chin back: there was a faint, broad mark around her neck, striated where the plastic had buckled into folds. “As you see, the ligature mark is well defined, hence my conclusion that it was put in place only when she had been immobilized. She shows no signs of strangulation, and I consider it unlikely that the ligature was tight enough to cut off the airway; however, petechial hemorrhaging in the eyes and on the surface of the lungs indicates that she did in fact die of anoxia. I would hypothesize that something along the lines of a plastic bag was placed over her head, twisted at the back of the neck and held in place for several minutes. She died of suffocation, complicated by blunt-force trauma to the head.”

“Hang on,” Cassie said suddenly. “So she wasn’t raped after all?”

“Ah,” Cooper said. “Patience, Detective Maddox; we’re coming to that. The rape was post-mortem, and was performed using an implement of some kind.” He paused, discreetly enjoying the effect.

“Post-mortem?” I said. “You’re sure?” This was a relief in the obvious way, eliminating some of the most excruciating mental images; but, at the same time, it did imply a special level of wacko. Sam’s face was pulled into an unconscious grimace.

“There are fresh abrasions to the exterior of the vagina and to the first three inches of the interior, and a fresh tear in the hymen, but there was no bleeding and no inflammation. Post-mortem, beyond a doubt.” I felt the In the Woods 87

collective, panicky flinch—none of us wanted to see this, the thought was obscene—but Cooper gave us a tiny amused glance and stayed where he was, at the head of the table.

“What kind of implement,” Cassie said. She was staring at the mark on Katy’s throat, intent and expressionless.

“Inside the vagina we found particles of earth and two minute splinters of wood, one severely charred, the other overlaid with what appears to be thin, clear varnish. I would postulate something at least four inches in length and approximately one to two inches in diameter, made of lightly varnished wood, with considerable wear, a burn mark of some kind and no sharp edges—a broom handle, something along those lines. The abrasions were discrete and well defined, implying a single insertion. I found nothing to suggest that there was also penile penetration. The rectum and mouth showed no signs of any sexual assault.”

“So no body fluids,” I said grimly.

“And there appeared to be no blood or skin beneath her fingernails,” said Cooper, with faint, pessimistic satisfaction. “The tests are incomplete, of course, but I feel I should warn you not to place too much hope in the possibility of DNA samples.”
