Hampton Sides - Hellhound on His Trail - The Stalking of Martin Luther King, Jr. And the International Hunt for His Assassin

Wood said that Harvey Lowmeyer had first come into Aeromarine the day before the date on the invoice. On that day--Friday, March 29--he purchased a Remington Model 700 .243, but called back later to say he wanted to exchange it for something more powerful. "My brother says I got the wrong one," Lowmeyer had said. Wood told Lowmeyer he could come back the following morning and make the exchange.

As agreed, Lowmeyer had walked into Aeromarine the next morning. Wood told Lowmeyer it would take a while to remove the scope from the .243 and mount it on the .30-06. Around three o'clock, Lowmeyer returned. Wood put the Gamemaster in an old Browning box. Lowmeyer bought some Remington-Peters ammunition and completed the transaction--paying in cash.

What did this Lowmeyer look like?, Agent Shanahan asked.

To Wood, he seemed like a "meek individual"--soft-spoken, mumbly, nervous. He recalled that Lowmeyer wore a slightly rumpled dark brown business suit with a white shirt and a tie. He was approximately five feet eight inches tall, weighed about 160 pounds, and looked to be in his mid-thirties. He had a medium complexion. His dark brown hair was swept back from his forehead.

Through Wood, Shanahan located a regular Aeromarine customer named John DeShazo who had spoken with Harvey Lowmeyer in the store the day he bought the original .243 rifle. An NRA loyalist who often spent hours at a time inside Aeromarine, DeShazo confirmed Wood's version of events, as well as his description of Lowmeyer, but he added a few details. DeShazo had smelled alcohol on Lowmeyer's breath. "He wasn't drunk, 491bleary-eyed, or slurring his speech," DeShazo said, "but he'd definitely been drinking."

DeShazo went on: "The man gave the impression that he was not from Alabama. He didn't look like a hunter or an outdoorsman. He appeared out of place in the store, didn't know a thing about rifles and had no business getting one. I thought at the time that this is the type of guy who buys a rifle to kill his wife--the type of guy who gives the use of weapons a bad name."

31 LOOPS AND WHORLS, LANDS AND GROOVES

AT THE FBI Crime Lab 492in Washington, the fingerprint expert George Bonebrake spent the early-morning hours of April 5 poring over the contents of the package that had been couriered up from Memphis. A slight, fastidious man, Bonebrake was one of the world's foremost authorities on dactyloscopy, the study and classification of finger and palm prints. Bonebrake had worked as a fingerprint examiner for the FBI since 1941. His was an esoteric profession 493within the crime-fighting universe--more art, it was said, than science, a closed world of forensic analysis predicated on a foundation of facts so incredible that a thousand bad TV detective shows over the decades had done little to diminish the essential mystery: that the complex friction-ridge patterns on human fingertips and palms, unique to every individual on earth, carry trace amounts of an oily residue excreted from pores that, when impressed upon certain kinds of surfaces, can be "raised" through the use of special dusting powders or chemicals--and then photographed and viewed on cards.

As far-fetched as the discipline seemed to most laymen, fingerprint analysis by 1968 had been the standard technique of criminal identification for more than half a century. It replaced a bizarre and not terribly accurate method of French origin called the Bertillon system, which required the careful measuring of a criminal's earlobes and other anatomical parts. Fingerprinting wasn't perfect, but it was the best system in existence for narrowing the pool of potential culprits in many situations. In many cases, fingerprinting was a godsend, providing the breakthrough that solved the crime.

In 1968, the FBI categorized fingerprints according to the Henry classification system, which was developed by Britain in the late nineteenth century. The system recognizes three primary friction-ridge patterns--arches, loops, and whorls. Loops, the most common pattern, are assigned a numerical value according to the number of ridges contained within each pattern found on each digit. Loop patterns can be further described as "radial" or "ulnar," depending on which direction their microscopic tails point.

Bonebrake got started with his meticulous work shortly after dawn. Most of the prints that he found were fragments or smudges that contained little or no information of value. The twenty-dollar bills that Mrs. Bessie Brewer had provided yielded no usable prints whatsoever. Eventually, however, Bonebrake was able to lift six high-quality specimens from the Remington rifle, the Redfield scope, the Bushnell binoculars, the front section of the Commercial Appeal , the bottle of Mennen Afta aftershave lotion, and one of the Schlitz beer cans.

Most of these prints appeared to come from different fingers, but already Bonebrake could tell that two of the prints--those taken from the rifle and the binoculars--were from the same digit of the same individual. Both seemed to have been deposited by a left thumb, and, upon further study, the print pattern would turn out to be unmistakable: an ulnar loop of twelve ridge counts.

This was an important find. The FBI had the fingerprints of more than eighty-two million individuals on file--a number obviously too large to work with, as fingerprint examiners had to do all matching the old-fashioned way, by hand, eyeball, and magnifying glass. This tiny little detail, however, narrowed the search considerably: an ulnar loop of twelve ridge counts on the left thumb. Bonebrake's task was still formidable, but now he had something definite on which to draw comparisons. He made large black-and-white blowups of all six of the latent prints, and then he and his team got started.

ON ANOTHER FLOOR of the FBI Crime Lab, Robert A. Frazier spent the morning 494examining and test-firing the Remington Gamemaster after it had been dusted for fingerprints. A ferociously methodical man with nearly three decades' experience, Frazier was the chief of the FBI's Firearms Identification Unit, where a team of ballistics experts worked around the clock in what was widely considered the world's preeminent weapons-testing facility. Here technicians fired rifles into water recovery tanks, examined bullet fragments and firearms components under high-powered microscopes, and subjected objects to arcane tests to detect such things as the presence of gunpowder and lead.

Within a few hours, Frazier and his team had made a long list of important preliminary findings.

First, the projectile which Dr. Francisco had extracted from Martin Luther King's body only a few hours earlier was a .30-caliber metal-jacketed, soft-nosed bullet made by the Remington-Peters Company--identical in manufacture to the unused Remington-Peters .30-06 rounds found in the ammo box that was part of the bundle.

Second, Frazier was able to ascertain the kind of barrel from which the bullet was fired. The barrels of modern firearms are "rifled" with spiral grooves that are designed to give bullets a rapid spinning motion for stability during flight. The raised portions between the grooves are known as lands. The number, width, and direction of twist of the lands and grooves are called the class characteristics of a barrel, and are common to all firearms of a given model and manufacture. Frazier determined that the bullet that killed King had been fired from a barrel "rifled with six lands and grooves, right twist," and that the Gamemaster, analyzed under a microscope in his laboratory, exhibited the same land-and-groove pattern.

Third, the spent cartridge that Special Agent Jensen had removed from the chamber had been fired in the same Gamemaster rifle, as evidenced by a tiny "extractor mark" Frazier found imprinted on the metal casing. At the base of this spent cartridge case, Frazier discovered a head stamp that said, "R-P .30-06 SPRG," indicating that it was a Remington-Peters round of the same caliber as the ammunition found in the ammo box.
