The two men had faced off nine years earlier, when Sorensen pulled Kueck over for reckless driving on a desert road at high noon. Kueck accused him of being a phony cop, and Sorensen radioed for backup. Furious, Kueck spent months trying to get the deputy fired, writing letters to everyone from Internal Affairs to the FBI.

Now, as Sorensen headed onto Kueck's property, it was almost high noon again, 110 degrees in the shade. Sorensen passed a no trespassing sign and cautiously proceeded down the dirt road toward Kueck's tiny trailer, spotting abandoned cars and mountains of junk everywhere. In a few minutes, his brains would be in a bucket.

Kueck, like all desert creatures in the midday heat, was probably lying low. A hermit who had lived in the Mojave for nearly thirty years, he had a thing about snakes. He kept a Mojave green, one of the most lethal reptiles in North America, at his front door, the rippling embodiment of the great battle cry "Don't Tread on Me."

The Mojave-a desert nearly as large as Pennsylvania -has historically been a haven for people who hate the system, from Charles Manson to Timothy McVeigh, and Kueck was no exception. A psychotic ex-con who fed his anger and self-recrimination on a cocktail of meth and Darvon and Soma, he had moved out here to get away from society's relentless demands for smog checks and food-stamp registration and housing permits. But now that system was closing in on his front door, in the form of a deputy with a gun.

According to the disjointed account that Kueck gave later, he was in bed when Sorensen arrived. "What's up, buddy?" he asked. The deputy told him to step outside, but Kueck, perhaps half-tweaked after a weeklong speed binge, believed Sorensen was there to hurt him, maybe even evict him. Although Kueck wasn't trespassing-he was living on land bought for him by one of his sisters-he knew he was in violation of a myriad of codes, eking out an existence in a ramshackle trailer without the proper permits. Worst of all, he feared going back to jail-"a concentration camp," as he called it. Confronted by Sorensen, he felt like he was down to his last card. "I figured I better dig up the old rifle and shoot him," he admitted later.

What happened next, according to police, is that Kueck kicked open his front door, aimed his Daewoo at Sorensen, and blasted him with.223s.The high-velocity bullets screamed into the deputy's body below his vest, shattering and buckling him like a piece of glass as he spun around and managed to get off three shots before Kueck blasted into Sorensen's right side and arm, tearing the 9mm from his grasp as rivulets of blood quenched the Mojave's hot sand.

But Kueck wasn't finished.We know from witnesses who heard the shots that a second volley of bullets was fired, and we also know from the coroner's report that Kueck put a round directly into Sorensen's face. He kept firing into the deputy's torso, using the rifle like a stiletto to carve up Sorensen's insides.When it was over, Kueck had raked the deputy's body with fourteen shells.

Unbeknownst to Kueck, he was being watched. After hearing the shots from their home a mile away,Wayne Wirt's wife and kids had climbed a tower and now, through a scope, observed Kueck ransacking Sorensen's Ford.They immediately dialed 9ll. Kueck disappeared from their view; he was on his knees, hidden by the SUV, tying a rope around Sorensen's legs, crisscross, crisscross, trussing him like a bagged deer, right ankle over left. He dragged the body toward the back of his yellow Dodge Dart and tied it to the bumper. Then he picked up the deputy's brains and threw them in a bucket.

As sirens wailed across the Mojave, Donald Charles Kueck vanished. A few minutes later the phone rang at his daughter's house. "I'm sorry," he said in tears. "I won't be coming over on Monday." In a land infamous for its outlaws, Kueck was about to become the target of one of the largest manhunts the desert had ever known.

At the report of gunfire, a Code 3-"Deputy needs assistance"-went out. Within minutes, dozens of patrol cars from nearby towns and counties were screaming across Highway 138 toward Kueck's trailer. In Long Beach, a Sikorsky H-3 helicopter took off carrying five deputies, and a three-man SWAT team scrambled aboard a chopper in East Los Angeles and headed for the scene.

The first to arrive was Sgt. Larry Johnston, followed by Officer Victor Ruiz of the California Highway Patrol. Johnston spotted spent shell casings and human tissue all over the blood-soaked sand in front of the trailer. There was Sorensen's SUV, its passenger door flung open, his two-way radio gone. But the Dodge Dart was missing, and Sorensen himself was not in sight.Was he being held hostage? Was he bleeding to death in a nearby desert wash? Did the assailant have them in his sights just waiting to ambush two more cops? Other deputies arrived and helped Johnston set up the first perimeter. Ruiz got in his Crown Victoria, siren shrieking, and followed a set of deep and freshly made tire grooves leading away from the bloody site.

As the SWAT team landed in the brush, Ruiz saw the body. "I went to listen for his carotid, and there was nothing," he says. "It looked like he took a round to the eye because it was pushed in. Then I saw that his head was flat.When I looked inside, there was no brain." The SWAT guys teared up at the sight of a fellow deputy reduced to a pile of mangled flesh. A commander told them to suck it up and someone said a prayer, and then they put a blanket over Sorensen's body lest the news media, now swarming the skies like vultures, broadcast the scene on the evening news.

"This was the most bizarre murder of a sheriff I have ever seen," recalls Detective Joe Purcell, a thirty-year veteran of the department. A vicious cop-killer with an automatic weapon was on the loose, and the search rapidly expanded beyond the sheriff's department. In 1873, the bandito Tiburcio Vasquez eluded a mounted posse in this very region for a year; two centuries later, Kueck was contending with an arsenal developed for modern warfare. A few miles away, air traffic control at Edwards-one of the world's largest Air Force bases-picked up the news and passed it on to the pilots who fly over the desert every eight minutes on maneuvers. The FBI dispatched a super-high-tech signal-tracking plane to pinpoint

Kueck if he used his cell phone, picking up his signal as it bounced off local radio towers. By the end of the afternoon, as backup poured in from other desert towns, Lake Los Angeles had become the Gaza Strip-no one was getting in or out without showing ID; every parolee in every trailer park and tattoo joint in the Antelope Valley was hauled in and questioned. Officers from all over Southern California combed Kueck's property and the surrounding desert, looking under every rock, behind every Joshua tree, deep into animal lairs and wrecked muscle cars and down ancient gullies and washes. Less than two hours after Kueck shot Sorensen, the SWAT team found his yellow Dodge Dart two and a half miles from the deputy's body. A dog from a K-9 unit picked up a scent at the car and led deputies to an abandoned shed about fifty yards away, through a dilapidated doorway, still on the scent, right to Sorensen's notebook, hat, and empty gun belt.

But if the cops thought all their manpower and technology would flush out the killer, they didn't know who they were up against. Inside Kueck's trailer, a team of criminalists found a pack rat's library of books on electronics, telescopes, aeronautics, the geology of the nearby Los Angeles Aqueduct, and time travel. Kueck's family confirmed what the evidence suggested-he was a self-taught scientist who, as one of his sisters put it, could "hook up a tin can to a cactus and power a city," a desert savant who built model rockets and talked physics with engineers at secret military test sites in his back yard, a wilderness expert who could survive in the mine shafts and buttes of the Mojave for a long time with nothing but his gun if he had to. He knew the desert's secrets and now became one himself-burrowing under a rock like one of his beloved snakes, or vanishing into one of the countless tunnels rumored to honeycomb the desert, underground hide-outs used by survivalists and meth cooks and lunatics. At one point, he told his daughter while on the run, he coiled under a piece of cardboard in a desert wash, watching the boots of his hunters as they tramped past. Kueck had studied the desert's creatures like a shaman, fascinated with the idea of shape-shifting into a coyote or bobcat or raven and then fading into the scenery until the light changed or the pact he had sealed with whatever dark force had come to an end. Even if it was only in his mind, it gave him an advantage, a mental edge. Some people know how to blend into a crowd. Kueck knew how to vanish into empty space.
