“I’m not an evidence technician,” I reminded him.
“But you’re great with taphonomy,” Roper said. I was impressed the D.A. remembered the term. In archaeology, taphonomy referred to the process or circumstances of fossilization, but forensic anthropologists tended to use it more broadly, to describe the arrangement and relation of bodies, bones, and any other environmental or human-produced evidence that could shed light on a murder or its timing. Postmarked letters, a week-old newspaper open to the sports page, milk or meat tagged with a sell-by date, even a year-old sapling or a seasonal wasp nest within a rib cage or an eye socket—all these could be considered taphonomic evidence of when a murder occurred.
“I’ll be glad to take a look at the taphonomy,” I said. “Be good for me to get out of the office.”
“The car’s at the KPD impound lot,” he said. “When do you want to see it?”
“How about early in the morning,” I said, “while it’s a mere ninety degrees?”
“I’ll have my investigator, Darren Cash, meet you at the impound lot. Just so you know, we’re getting ready to ask a grand jury to indict Stuart Latham for first-degree murder, based on the insect evidence you found in the skull. First, though, we’ll get a search warrant to go back for another look at the property. If you find anything else in the car, that could help with the warrant.”
“I’ll see what I can do,” I said, “but don’t hold your breath. What time should I meet Cash?”
“How does nine o’clock sound?”
“Sounds late and hot,” I said. “What about eight instead?”
“I’ll have Darren meet you at eight.”
“You mind if Art Bohanan comes along? He wasn’t available when the KPD forensics team went over the car.”
“I’m always glad to have Art take a look.”
AT 7:55 THE NEXT MORNING, Art and I turned onto the lane leading to the KPD impound lot. The lot was on a dead-end street in East Knoxville, directly across I-40 from the zoo. Something about the juxtaposition struck me as funny—hundreds of captive animals on the south side of the interstate, I realized, hundreds of captive vehicles on the north side. As we entered the dead end, I imagined a mass escape from the zoo: animals tunneling under the freeway, then speeding off in stolen cars and trucks—chimpanzees and gorillas driving the getaway vehicles, hippos and elephants hunkering in the back of the biggest trucks. I pointed out a car to Art, a red BMW convertible with the top down. “You think a giraffe could fit into the back of that Beemer?”
Art glanced at me, then at the car, then stared at me as if I were some sort of zoological specimen myself. He raised his eyebrows slowly, then shook his head, an expression of deep pity on his face. “We have got to get you some professional help,” he said.
“Come on,” I said, “it’s not that far-fetched. Primates have opposable thumbs—they could hot-wire the ignitions.”
“Professional help,” he said again. “A mind is a terrible thing to lose.”
The impound lot was a quarter mile long—four narrow lots, actually—sandwiched between the interstate on one side and a set of railroad tracks on the other. The first lot, an unfenced pad of gravel about fifty yards square, contained vehicles that would be auctioned off on September 1, a sign announced. These were unclaimed or forfeited cars and trucks, along with several horse trailers, which particularly intrigued me. Surely I could find a use for a cheap horse trailer at the Body Farm, I thought.
The second lot was a fenced expanse of asphalt measuring the same fifty yards deep—the depth being dictated by the train tracks bordering the back—but stretching a hundred yards long. This lot held vehicles that had been towed for a multitude of reasons: Fire hydrants had been blocked, parking meters had gone unfed for weeks on end, junkers had been abandoned alongside the interstate, unpaid traffic tickets had mounted to thousands of dollars. Many of the vehicles had open windows, and several, like the red BMW, were convertibles open to the elements. “Good thing for those convertibles we’re in the middle of a drought,” I said.
Art shrugged, unconcerned. “If the top’s down or the windows are open when we tow it, nothing we can do. We don’t have the keys.”
I noticed a video camera mounted on a pole at one corner of the lot. “Have you had break-ins, right here in the impound lot?”
“You wouldn’t believe what a problem it is,” he said. “We had one guy sneak in with wire cutters one night, cut a big hole in the fence, and drive away.”
“He hot-wired one of the cars?”
“He had the keys. It was his car.”
“He stole his own car from the police?” I couldn’t help laughing. “Did y’all catch him?”
Art shook his head. “We got the car back—he ditched it over in North Carolina—but we never got the guy.”
