“Hard to argue with results,” he said. “Hey, do me a favor, since I’m using both hands? Come hit ENTER on the keyboard there, to accept the print and let me get the next one.”
I did, for the thumbprint and each of the four fingerprints. Once he had finished scanning the prints, Art returned the skin to the jar, screwed the lid on snugly, and handed it back to me. Then he peeled off his gloves and tossed them in a container labeled BIOHAZARD. He went back to the laptop and clattered the keys for a few minutes, then hit the ENTER button with a flourish. “Okay, they’re sent,” he said. “We should have an answer within a couple hours.”
“How can it be so quick? You said there are nearly fifty million sets of prints in the database, right? That’s nearly five hundred million fingertips to compare.”
“I guess the software’s pretty powerful, and their mainframe has a lot more horse power than our little personal computers,” he said. “I mean, it’s easy to narrow it down.” He hit a few more keystrokes, and the thumbprint reappeared on the screen. “Prints have one of three basic patterns,” he explained, “whorl, loop, and arch. Whorls are concentric circles-like a target with a bull’s-eye at the center, or the cross section of an onion. A loop pattern is more complicated; the ridges come in from one side, make a U-turn, and go back out the same side. In an arch pattern, the ridges come in from one side, go up in the middle, and then go out the other side.”
I studied the pattern on the screen. “So our guy has a whorl pattern,” I said. “At least on his thumb.”
“Bingo,” said Art. “So when the AFIS software is looking for a match for this particular print, it searches only right-hand thumbprints, and only those with whorls. That means it only needs to compare this print with, I dunno, maybe twenty million others. Still a lot, but there are other criteria and features that can progressively narrow that down tighter and tighter.” He pointed to two areas on the print where the circular pattern of ridges gave way to a triangular intersection, as if the whorl had been shoehorned into an arch pattern. “See those? Those are called deltas. Pretty easy to tell if the deltas on one print are spaced differently from the deltas on another. I’m not a software guy, but I imagine it would be fairly straightforward to program a computer to recognize features like deltas and compare their locations on an X-Y coordinate system.”
Art promised to let me know later in the day if AFIS returned any hits on the prints. “I can’t access AFIS from the computers at the pawnshop,” he said, “but I’ll dash over here at lunchtime and see if we got lucky.”
He rode down the elevator with me and we walked out into the crisp morning sunshine. I was headed to UT to teach Tennessee’s brightest and best. He was headed to Broadway Jewelry amp; Loan to stalk Tennessee’s darkest and worst. “Thanks, Art,” I said. He nodded and headed for his car. “Hey,” I called after him. “Go get ’em, Tiffany.” Without looking back, he raised one hand in a parting wave. His middle finger was extended. The gesture was aimed not at me, I knew, but at the men who were his quarry. The predators out there lurking in cyberspace, waiting to pounce.
CHAPTER 17
AT 10:50 A.M., I strolled around the curve of Circle Drive toward McClung Museum, where my eleven o’clock forensic anthropology class met. An event of some sort seemed to be taking place outside the museum. The small plaza at the museum’s entrance was filled with people and banners. As I got closer, I realized that the event was a protest, and what I had thought were banners were actually neon-hued picket signs.
I took mental inventory of the museum’s current exhibits, wondering which of them could have sparked controversy. The exhibition of nineteenth-century Samurai swords, prints, and other artifacts? Surely not. “UT Goes to Mars,” photos, videos, and models documenting the role several UT faculty played in NASA’s Mars Rover landings? Doubtful; I’d not read of fans of, say, Venus lobbying NASA for equal time. “The Origins of Humanity,” a show that included fossil remains from human ancestors, as well as two life-size reconstructions of early hominids? Hmm. That could fit, I realized, judging from my own recent brush with the hornet’s nest of creationism.
As I drew near enough to read the picket signs, I spotted a disturbingly familiar word on many of the signs. It was my own name, and I realized with a jolt that the picketers weren’t protesting an exhibit; they were protesting me, Bill Brockton, Darwin’s loudest local mouthpiece. DR. BROCKTON HAS NOT EVOLVED, read several of the signs. BROCKTON MONKEY’S WITH GODS CREATION, read a few others, combining dubious theology with appalling apostrophe usage. Some simply bore a stylized drawing of a fish, an ancient symbol of Christianity. And one, carried by someone wearing a gorilla costume, even featured a life-size photo of my head pasted atop the cartoonish body of a chimpanzee. A television news crew was on the scene, getting close-ups of the picketers as they marched in an oval, blocking the doors to the museum.
A half dozen UT police officers were arrayed a tactful distance from the protesters. I sidled up to the closest one to learn what I could about the group. “When did this all start,” I asked him, “and who are these folks? They don’t look like UT students.” Except for the gorilla suit, their clothing was more conservative than anything I’d ever seen on UT students in de cades. The boys and men wore dark pants, white shirts, and ties; the girls and women wore long dresses and clunky shoes, and there was not a pierced navel or tattoo anywhere in sight.
“They showed up about twenty minutes ago,” the officer said. “They must have known your class schedule. A church bus pulled into Circle Drive and unloaded, then drove off to park, I’m not sure where.”
“Did you notice what church it was from?”
“Nothing I ever heard of. ‘True Gospel Fellowship,’ or maybe ‘True Fellowship Gospel’? I never heard of the place, either. Some town in Kansas.”
“Kansas,” I said. “Why am I not surprised?”
“That guy in the monkey suit seems to be the cheerleader,” the officer said, “but I’d say the fellow off to the side there is calling the plays.”
I followed his gaze. Standing apart from the knot of protesters, his hands clasped in front of a double-breasted gray suit, stood a well-groomed man of middle years. His hair was dark, going to silver; it was swept back from an imposing forehead, and either it was naturally wavy, or it had been carefully styled to look that way. I noticed French cuffs and gold cuff links peeking out the ends of his jacket sleeves, and his trouser cuffs draped over sleek black shoes that spoke of money in an Italian accent.
I took a wide detour so as to come up behind him. “Nice signs,” I said as I eased alongside. “My favorite is the one with the picture.” He gave a brief, practiced chuckle, then turned toward me to make conversation. When he saw my face, he looked startled but quickly recovered his composure. “I’m Bill Brockton, anthropologist and evolutionist,” I said. “I’m guessing you’re Jennings Bryan, attorney and creationism activist?”
“Not creationism,” he said pleasantly. “Intelligent design. Please.” He smiled slightly, as if acknowledging a worthy adversary. “The famous Dr. Brockton,” he said. “Please forgive me for not shaking hands. It would complicate things for me, for the cause, if the newspapers or TV captured a handshake on film.”
“Well, I’d hate to complicate things,” I said. “I struggle even when they’re simple.”
“I hear otherwise,” he said.
“Well. For what ever it’s worth, I am sorry I embarrassed that boy in class.”
“I’m not,” he said. “You did us a huge favor.”
