From Sword of Jesus: The Rise of Christian Extremism in the United States, by Edith Janko:
...As the SUV charged towards them, the police manning the roadblock concentrated all their fire on it in the hope of taking out the driver and thereby sending the vehicle out of control; however, with it approaching at 120 mph and with their own forces suffering attrition from the Crusaders’ gunfire, they did not manage to kill or incapacitate the driver before they were forced to dive away from the speeding vehicle. Although they raked it with fire as it shot past and down the road away from them, its occupants did the same to the police cars, and it passed out of sight still under control. It was hoped that the second SUV, this one not charging nearly so fast as the other, would prove easier to stop, but its occupants, seeing the stiff fight put up by the police against the first vehicle despite its fast and presumably terrifying charge, decided not to bother with trying to run the gauntlet and instead pulled out their trump card: as the second SUV approached the roadblock from a distance, one of its occupants leaned out of one of its windows and let loose with a rocket launcher, which hit and completely destroyed one of the police cars and badly damaged the other with its blast, killing everyone in the first car and killing or seriously wounding everyone in the second. None of the survivors were in any way capable of further resistance, and they expected to all be summarily shot when the second SUV pulled up; fortunately for them, the Crusaders had more police on their tail and knew it, and as such did not stop for an execution, instead proceeding through the strewn wreckage of the roadblock at high speed (and in the process taking full advantage of their vehicle’s run-flat tires, which they had installed to deter spike strips but which also worked perfectly well for shattered fragments of roadblock and police car)...
…When the pursuing police cars pulled up to the shattered wreckage, they, not being equipped with run-flat tires, instead came to a screeching halt. Their occupants jumped out with guns drawn, but seeing no Crusaders in the vicinity, instead went to the aid of the two badly injured policemen and single policewoman in the non-destroyed car and put in calls for ambulances, backup, and road-clearing personnel. Meanwhile, the Crusaders had raced ahead on Interstate 10, and managed to slip by the police manning the Banning roadblock, who had heard the rocket explosion at the West Beaumont roadblock and immediately drove to the scene; in a stroke of extraordinarily bad luck, their cars, going west, passed the Crusaders in their SUVs going east on the other side of I-10, and did not recognize them or their occupants for who they were…
...We now know that the remaining six Crusaders did not have a preconceived plan of where they were going to escape to after fleeing Yorba Linda; as a result, they turned off of I-10 and took CA-62 north and then northeast before turning into Joshua Tree National Park. With its fairly open desert landscape, Joshua Tree was far from the best choice for even a temporary hideout, further underlining their lack of preparedness for the aftermath of a successful escape. Nevertheless, after they drove off into the desert to hide their SUVs, stashed their weapons under the seats, and hiked to Cottonwood Campground, where they filled their water tank (which, though it provoked a few inquiring glances, did not ring any alarm bells, the campers at Cottonwood not yet having heard about the Yorba Linda bombing and the West Beaumont engagement) and wheeled it back along the road and then off into the desert; after hauling it into the back of one of the SUVs, they discussed strategy long into the night. Although one of the six staunchly favored heading north into the Sierra Nevada, and another proposed that they should continue east into Arizona for an attack on targets there or further east (his own favored targets being Hoover Dam and the Glen Canyon Dam, the destruction of either of which would cause massive flooding along the entire lower Colorado; he apparently had wildly inaccurate assumptions as to how much explosive would be required to take down either of the dams), the option that finally won out was to zigzag south and make for the Mexican border…
...They started out at dawn, getting, with some difficulty, the two SUVs back onto the road, and immediately hightailed it south out of Joshua Tree National Park and then southwest to Mecca. At this point, the Crusaders turned onto CA-86 and headed south along the western shore of the Salton Sea, before jagging west and then south on the backcountry roads through Borrego Springs to CA-78. At Julian, they turned south onto Highway 79, and followed it all the way to the junction with Old Highway 80. This they did to avoid I-8, which by now was crawling with police cars and studded by roadblocks, and in this respect they were successful; they encountered only one roadblock, which they got through with one round from the ever-reliable rocket launcher. Unfortunately, the launcher’s use drew the attention of all those police along I-8, and they quickly picked up the trail as the Crusaders hurried south on S1 to the junction with CA-94; as the Crusaders approached Campo, one of them glimpsed a police APC lumbering onto the highway half a mile on, and they therefore made the very risky decision to run down Forrest Gate Road to the border. They must have thought they had gotten away clean, for they slowed down as they paralleled the border, allowing a sharp-eyed policewoman included among the forces combing Campo to spot them approaching the border crossing into Mexico; as police cars started racing down Forrest Gate towards them, the Crusaders forced their way through the crossing, increasing the death toll of their mad dash of an escape so far to 32 police officers and 6 Border Patrol agents, and fled into the Baja California desert…
...The Mexican Army played the major part in the hunt for the fugitive Crusaders, having gained considerable experience taking down drug lords all over Mexico, and acquitted itself extremely well in tracking down the fleeing terrorists. The Crusaders initially drove east along Mexican Highway 2, but east of Puebla they found their path blocked by Mexican infantry, and attempting to use the same formula that had gotten them through two roadblocks and a border crossing, they found out, only got four of the six remaining Crusaders killed and one of their SUVs wrecked. Critically, the destroyed SUV was the one containing their water tank, and by this point, despite having several jerrycans in the back of the remaining vehicle, they were running low on fuel as well; two of the jerrycans had been holed in the firefight, and their high-speed flight west to Mexican Highway 5 and then south down it was using up fuel at an alarming rate. However, in the end, it was not lack of fuel that brought an end to the Crusade of God’s Los Angeles eastern cell, but instead the competence of the Mexican Army; slightly more than halfway to Delta Número Uno, they ran headlong into another infantry detachment. Knowing that they had no chance of escape, they instead opted to fight it out, and so the two remaining Crusaders, outnumbered nearly 20 to 1 and badly outgunned as well, fought and died in their version of a glorious last stand. Within 90 seconds of the start of their battle, the last two members of the L.A. eastern cell breathed their last...
