Certainly it was possible the killer struck her in the head and at some point later strangled her, perhaps not realizing she was already dead. But if so, how much time did he spend with her? Based on the contusion, swelling, and hemorrhage to the cerebral cortex of her brain, she had survived for a while, possibly hours. Yet there was very little blood at the scene. It wasn’t until the body was turned over that the injury to the back of her head was even noticed, a one-and-a-half-inch laceration with significant swelling but only a slight weeping of fluid from the wound, the lack of blood blamed on the rain.

Scarpetta seriously doubted it. The scalp laceration would have bled heavily, and it was unlikely a rainstorm that was intermittent and at best moderate would have washed most of the blood out of Toni’s long, thick hair. Did her assailant fracture her skull, then spend a long interval with her outside on a rainy winter’s night before tying a scarf tightly around her neck to make sure she didn’t live to tell the tale? Or was the ligature part of a sexually violent ritual? Why were livor and rigor mortis arguing loudly with what the crime scene seemed to say? It appeared she had died in the park late last night, and it appeared she had been dead for as long as thirty-six hours. Scarpetta was baffled by the case. Maybe she was overthinking it. Maybe she wasn’t thinking clearly, for that matter, because she was harried and her blood sugar was low, having eaten nothing all day, only coffee, lots of it.

She was about to be late for the three p.m. staff meeting and needed to be home by six to go to the gym and have dinner with her husband, Benton Wesley, before rushing over to CNN, the last thing she felt like doing. She should never have agreed to appear on The Crispin Report. Why for God’s sake had she agreed to go on the air with Carley Crispin and talk about postmortem changes in head hair and the importance of microscopy and other disciplines of forensic science, which were misunderstood because of the very thing Scarpetta had gotten herself involved in-the entertainment industry? She carried her boxed lunch through the loading dock, piled with cartons and crates of office and morgue supplies, and metal carts and trollies and plywood.
