I’d assumed wrong. After an hour of searching and sifting, we were still empty-handed. Had the force of the impact somehow caused one of the teeth to ricochet away from the others? Or had a single tooth been planted in the wreckage, as a red-herring hoax? If so, by whom, and for what purpose?
By late morning, we’d sent up four loads of debris without having found any more teeth or bones, and my mood had gone from buoyant to discouraged to downright mad. So when a tangle of metal tubing resisted my efforts to remove it from the wreckage, I gave a furious tug. Suddenly, unexpectedly, it came free and I toppled backward, my arms windmilling for balance. Catapulted by my flailing, a lumpy object—it looked like a charred chunk of driftwood pulled from a riverbank campfire—arched into the air, tumbling end over end. Blackened and broken though it was, I recognized it at once. I made a scrabbling lunge for it and managed to catch it just before it hit the rocks.
“Nice catch,” said Boatman, on all fours, one hand working a shard of riveted aluminum free from a crevice. “You been practicing with the UT football team?”
“No, but I feel like I just scored a touchdown,” I said. “Guys, this is the pelvis. Part of it, anyhow.” The FBI techs came closer, careful not to disturb anything in the vicinity where the pelvis had been. “That tangle of tubing must be the framework of the seat.” As I leaned down for a closer look, I felt my heart race even faster. “It is,” I said. “I see vertebrae in there, too!”
“Wow,” said Kimball, crouching alongside me. “Hard to tell where the seat leaves off and the skeleton begins.”
“The man and the machine are pretty thoroughly mashed together,” I said. “That whole aircraft—twelve thousand pounds—slamming into him like a pile driver, at four hundred miles an hour? I’m surprised it’s not even more fragmented than this.” I rotated the piece, studying what remained of the pelvis, then—on professorial autopilot—began pointing out structures. “This curved, triangular piece is the sacrum—the base of the spine, where it joins the pelvis. The sacrum is made of five vertebrae, and in children and adolescents, they’re separate. But here, you can see, they’re fused together. That tells us that this person was an adult; midthirties, at least.” I pointed to the narrowest tip of the triangle. “The coccyx—that’s the tailbone—attaches here, but it’s been snapped off.” I rotated the piece again. “Both pubic bones are broken, too. That makes it harder to tell the sex. So let’s look at the sciatic notch, which is this gap where the sciatic nerve runs from the spine down the leg.” I cradled the piece in one palm, so the V-shaped notch faced upward, and then pressed the side of my index finger down into the V. “I know you guys might not’ve noticed, but a woman’s hips are broader than a male’s, so the sciatic notch is wider, too. If it’s a female, you can fit two fingers into the sciatic notch.” I tried, and failed, to squeeze my middle finger alongside the index finger. “Here, I can’t—the notch is too narrow. So we know he’s a he.”
Boatman must have been reading my mind. “Any way to tell how old he is?”
I shook my head. “It’s too damaged. Normally, you can tell the age—the decade, anyhow—from the wear on the pubic symphysis.”
“The what?” asked Boatman.
“The pubic symphysis. That’s the joint where the left and right pubic bones meet, just above your crotch.”
Kimball chuckled. “Boatman’s would look like a kid’s, then,” he gibed. “No risk of wearing out his pubic bones.” Grinning at his joke, he began taking photos of the pelvis and the mangled framework of the pilot’s seat. Suddenly, as he hovered over the seat, he said, “Guys, look at this!” He lowered the camera, letting it hang from its strap, and bent down to extricate a charred object from the mangled metal. It was thin and small—half the size of a deck of cards—with rounded corners and a pair of thin wires, about a foot long, dangling from it.
He held it in his palm, turning it over to inspect it. “This is a circuit board. And a battery, looks like. Holy crap—I think this is some kind of detonator.” He looked up, eyes wide. “Don’t move.”
He didn’t have to tell us twice. A detonator implied a bomb—possibly a live bomb. I flashed back to the explosion that had nearly brought down our helicopter the day we’d arrived. Maddox had thought it was an oxygen cylinder bursting, but maybe he’d been wrong. Our eyes moved—scanning one another’s faces; scanning the rocks and the ragged debris—but our bodies remained as motionless as statues.
