"Yes," she agreed.

"Though I've been in this building for many years, and I've seen a lot of things happening that shouldn't. I certainly wouldn't volunteer any information, but if someone asked me directly, I would feel compelled to tell them the truth." He smiled at her over his shoulder. "I suppose that would make me what you guys call a ‘rat.' "

She shrugged.

"Will is a good man who had to do a dirty job. I can relate to that." He pulled a handful of paper towels off the stack and dried his hands as he walked to his office.

"Sit," Pete said, indicating a chair by his desk.

Faith sat on the stack of papers in the chair, knowing Pete didn't expect her to move them. "What do you have so far?"

"Nothing of consequence, I'm afraid." He retrieved a paper bag from the small refrigerator in the corner. Faith concentrated on finding a clean page in her notebook as he took out a sandwich. "The girl was stabbed at least twenty-seven times. I would assume from angle and trajectory that the wounds match the kitchen knife you found at the crime scene. The killer was most likely on his knees, superior to the body, when he attacked her."

Faith wrote furiously, knowing he would not pause to let her catch up.

"There was bruising around her thighs and some tearing in the vaginal canal. I found traces of cornstarch, which indicates a condom was used, but we can assume from the sperm that the condom tore, as often happens with rough sex. Also, I noted some faint bite marks around the breasts. I would say this was more consistent with consensual sex, though that's really just speculation on my part."

He unwrapped his sandwich and took a bite, chewing with his mouth open as he continued. "You can certainly leave those kinds of marks by raping a woman, but then again, if you were feeling a little eager and the woman was willing, you could make an argument that the marks were left not by rape, but during a particularly ardent session of lovemaking. I wouldn't be surprised if, after a couple of bottles of tequila and some dancing, the current Mrs. Hanson happily exhibited the same sort of trauma."

She tried not to shudder. "The bite marks, too?"

There was a loud snap as Pete clamped his dentures together, and Faith wrote nonsense words in her notebook, praying he would stop. "So, you're saying that the girl wasn't raped."

"And as I told Agent Trent at the crime scene, there was semen in the crotch of the panties, indicating that after having sex, she put on her underwear and stood up. Now, unless the perpetrator raped her, made her dress and stand up, then chased her down the hall and killed her, then pulled down her panties again, then I would say that she was not raped. At least not during the attack."

Faith noted this word for word in her notebook.

Pete took another bite of his sandwich. "Now, as for cause of death, I would say there are three likely candidates: blunt-force trauma, the pierced jugular and just plain old shock. The nature of the attack was intense. There would have been a cascade effect with the body. There comes a time when the brain and the heart and the organs just throw up their hands and say, ‘You know what? We can't take this anymore.' "

Faith dutifully recorded his words. "Which one is your money on?"

He chewed thoughtfully, then laughed. "Well, an armchair coroner might go for the jugular!"

Faith managed a chuckle, though she had no idea why she was encouraging him.

"The jugular was sliced. I would say that, in and of itself, the cut was fatal, but it would've taken time-say three to four minutes. My official report will reflect the more likely culprit: massive shock."

"Do you think she was conscious during the attack?"

"If the parents ask you that question, I would tell them unequivocally that she was instantly rendered unconscious and felt absolutely no pain." He took a bag of potato chips out of the paper sack, leaning back in his chair as he opened them. "Now, the boy, not so much."

"What's your best guess?"

"It jibes with Will's theory. I can't believe how well he reads a crime scene." Pete popped a potato chip into his mouth, seemingly lost in thoughts of Will Trent's expertise.

"Pete?"

"Sorry," he said, offering her a potato chip. Faith shook her head, and he went on. "I haven't culled all my notes, but I think I have a clear picture." He sat up in the chair and drank from the Dunkin' Donuts cup on his desk. "Physically, he presents pretty straightforward. I already told you about the head wound. The stab to the chest alone was enough to kill him. I would imagine it was through pure adrenaline that he managed to put up the struggle he did. The knife punctured his right lung-easy math, we're looking for a left-handed killer-bypassing the bronchial trunk. We can assume the victim removed the knife, which exacerbated the negative airflow. The lung is vacuum sealed, you see, and a puncture deflates it much as a balloon being pierced by a pin."

Faith had dealt with a victim who'd died of a collapsed lung before. "So, unless he managed to get help, he only had a few minutes."

"Well, here's the funny thing: he would've been panicked, his breathing would have been shallow. When a lung collapses, it's like a self-fulfilling prophecy. You gulp for air, and the more you breathe, the worse it gets. I'd say that the panic bought him some extra time."

"What's the cause of death?"

"Manual strangulation."

Faith wrote down the words, underlining them. "So, Abigail Campano actually did kill him."

"Exactly." Pete picked up his sandwich again. "She killed him right before he died."

THE INTERIOR OF the morgue had spotty cell reception at best. Faith used this as an excuse to leave Pete to finish his lunch by himself. She dialed Will Trent's number as she walked toward the parking garage for some air. Faith needed to tell him about Mary Clark and Ruth Donner. She also wanted to talk about Kayla Alexander some more. The picture she was getting of the girl was not a pretty one.

Will's phone rang several times before she was sent to voice mail.

"Hi, Will-" Call-waiting beeped and she checked the screen, reading the words "Cohen, G." Faith put the phone back to her ear, not recognizing the name. "I'm just leaving the morgue and-" Her phone beeped again and Faith finally realized who was calling. "Call me," she said, then switched the line over. "Hello?"

"It's Gabe." His voice sounded far away, though she guessed he was still at Tech.

"What can I do for you?"

He was silent, and she waited him out. Finally, he told her, "I lied to you."

Faith stopped walking. "About what?"

His voice was so low she had to strain to hear him. "I thought she was younger."

"Who?"

"I've got…" His words trailed off. "I need to show you something Adam had. I should've shown you before, but I…"

She started to jog, heading toward the Mini. "What do you have of Adam's?"

"I have to show you. I can't tell you on the phone."

Faith knew that was bullshit, but she also knew that Gabe Cohen was ready to talk. She would dance like a monkey if it got the truth out of him. "Where are you?"

"The dorm."

"I can be there in fifteen minutes," she said, unlocking the door.

"You're coming?" He sounded surprised.

"Yes," she said, switching the phone to her other ear as she put the key in the ignition. "Do you want me to stay on the phone with you while I drive over?"

"I'm okay," he said. "I just…I've got to show you this."

She glanced over her shoulder and swerved the Mini out of the space so sharply that it squealed up on two wheels. "I'll be right there, okay? Just stay right where you are."

"Okay."

Faith had never driven so fast in her life. Part of her wondered if Gabe was just stringing her along, but there was always the slim chance that he had something important to tell her. She called Will Trent's cell phone again, leaving another message, telling him to meet her at the dorm. Her heart raced as she blew through red lights, nearly causing a bus to slam into another car, heading into oncoming traffic to whip around construction crews. On campus, she didn't bother to look for legal spaces, again parking the Mini in the handicapped section. She flipped down the visor and jumped out of the car. By the time she reached Towers Hall, she was panting from exertion.
