So given how thoroughly I despised the man and his tactics, why on earth was I about to testify for his team at a murder hearing? Because he had played me like a fish yet again, this time reeling me over to his side of the courtroom. It had happened a few weeks before, when he invited me to lunch—“to bury the hatchet,” he said—and sure enough, throughout the meal he was gracious and conciliatory, praising my research, praising my students, apologizing for his aggressive defense tactics. Then, during dessert, he cast the bait. He had a case he’d appreciate my advice about, he said, because it involved the most baffling forensic mystery he’d ever seen. He posed a series of innocent-sounding hypothetical questions about skeletal structure and sharp trauma—“When a person is stabbed, the knife blade can leave marks on the bones it contacts, can’t it? Can it leave metal particles from the blade, or residue from a sharpening stone? How much variation is there in the shape of the spine? What about suchand-such?” He paid rapt attention to my answers, then posed incisive follow-up questions. “Yes, but if the knife had a thin, flexible blade? If the victim had curvature of the spine?” After it was too late—as I lay flopping in his creel—I realized that he’d been setting the hook during that entire chocolate-fueled dialogue. Da Grease, clever bastard that he was, had appealed to both my scientific curiosity and my sense of justice. As he settled the tab, he concluded with a litany of troubling allegations about the autopsy Billy Ray Ledbetter had received at the hands of Dr. Garland Hamilton, the Knox County medical examiner. I, DeVriess had insisted, was the only hope for saving poor, innocent Eddie Meacham.
He was putting me in a delicate position. As an anthropologist, I’m not technically qualified to determine cause of death; in Tennessee that’s a call that can be made only by a physician with a specialty in forensic pathology—and, what’s more, by a pathologist who has been officially appointed as a medical examiner, a position that marries medical expertise with law enforcement powers. In the normal pecking order of the academic and forensic world, a forensic anthropologist with a Ph.D. was considered a rung below a medical examiner with an M.D. On the other hand, there were certain areas in which my expertise far surpassed the medical examiner’s, and one of those was skeletal structure and geometry. In addition to studying thousands of human skeletons and hundreds of corpses—including scores of mangled, murdered ones—I had also spent a year teaching human anatomy to medical students. So if a man’s life hinged on whether or not a knife blade could thread a zigzag path through the human back, spine, and rib cage, I felt confident that my skeletal research and anatomical knowledge more than equaled Dr. Hamilton’s medical degree.
“Off the record, Dr. Brockton, I’m gonna level with you,” Grease had leaned in and confided. “The vast majority of my clients are probably guilty of the crimes they’re charged with.” Golly, what a news flash that was. “Eddie Meacham is not. He did not kill Billy Ray Ledbetter. He’s being railroaded by an incompetent, impaired medical examiner—and by a prosecutor who doesn’t want to humiliate the ME and compromise his other cases. And for the sake of that, they’re willing to send an innocent man to prison for life. That’s wrong, and if I’ve learned anything at all about you over the years, Dr. Brockton, it’s this: you stand for the truth. Period. I’m begging you, set aside your personal feelings about me and speak the truth about this case and this sham of an autopsy. Eddie Meacham needs your help.”
God, he was good. For years I’d loathed him—today, settling into the witness chair, I loathed him still—but sitting in that restaurant a few weeks ago, I couldn’t help admiring his skill and what appeared to be his passion. I also couldn’t resist his plea to exercise my best judgment and do whatever I thought was right. Flattery? Probably. But wasn’t it possible to be flattered and right?
And what was right, I came to decide as I studied Dr. Hamilton’s autopsy report and my own collection of skeletons and corpses, was to take the stand and point out the impossibility of the medical examiner’s conclusions. Thus it was that I found myself on the witness stand this bleary-eyed morning, wielding bones and diagrams to explain skeletal geometry. Grease led me smoothly through it all, ending with the account of my futile attempt, the previous morning, to replicate the wound path described by the autopsy report. “In your expert opinion, then, Dr. Brockton—based on your extensive knowledge of skeletal trauma and on your own experimental investigation—is it even remotely plausible that the blade of a hunting knife followed that zigzag path through the body of the deceased?” It was not, I said. “Thank you, Doctor, for your candor and your courage,” he concluded, his voice breaking slightly with emotion. I half expected a tear to trickle down his cheek as he returned to the defense table and gave his client’s shoulder an encouraging squeeze.
At the prosecution table, Bob Roper stared morosely at his copy of the autopsy report, then rose to cross-examine me. Neither of us was looking forward to this. He began by leading me through a grade-school exegesis of the steps in the scientific method: observation, hypothesis, controlled experiment, conclusion. I wasn’t sure where he was headed with it, and I grew impatient as we covered the subject in numbing detail. Then I began to discern the trap he was setting for me. “You’ve done dozens of scientific experiments on human decomposition at your research facility, haven’t you, Doctor?” I acknowledged that I had. I could hear the jaws of the trap creaking open: “Dr. Brockton, do you consider reproducible results to be an important part of the scientific method?” Yes, I hedged, in general I do. “And yet you performed this experiment you’re testifying about today, the one you’re using to impugn the medical examiner’s autopsy, only once, isn’t that correct?” Snap!
“That is correct, but—”
