He shook his head. "Too dangerous. These guys aren't interested in getting killed. What they do is choose a 'mark' – usually someone in an expensive vehicle or a commercial van – anything with a likelihood of being well insured. A vehicle they call the 'squat' car positions itself in front of the mark. These drivers are tooling down the road at thirty-five miles an hour, everybody minding his own business. At a signal, a second car, called a 'swoop', cuts in front of the squat car, which brakes sharply, forcing the mark to rear-end it. The swoop car takes off. The squat and the mark pull over to the side like good citizens and exchange license numbers. At this point, the mark is usually pretty upset. Here, he's rear-ended another vehicle and he knows the responsibility is his. The driver in the squat car is full of sympathy – hell, he can afford to be – confirming just what the mark wants to believe, that it wasn't his fault."

"But his insurance company pays anyway," I said.

"Has to. You rear-end somebody, you're liable in this state. Turns out the squat's got all these 'problems' resulting from the accident. He sees a lawyer, who tells him he better see a doctor. Or he might be referred to a chiropractor..."

"All of them in cahoots..."

"All in cahoots," Lieutenant Santos said. "And Bibianna got involved in the ring through Raymond?"

"It looks that way. From the information we've pieced together, Raymond recruited her two years ago, though he's known her much longer. They were all set to get married about a year ago, but for some reason she pulled out. March, she did a disappearing act and a short time later surfaced in Santa Teresa. It looks, on the face of it, like she meant to go straight, but she had a hell of a time finding work. She finally picked up a job with a dry cleaning establishment, but it doesn't pay much, and in the end, I guess she couldn't resist trying a little scam or two of her own."

I was beginning to see how it all fit together. "And now my investigation has jeopardized yours."

"Not yet, but it looks like you're getting close. We can't afford to have you blundering in unawares, which is not the only problem we face. It looks like we've got a leak somewhere, critical information spilling through the pipeline into Raymond's ear. On at least three occasions, we've had raids set up... most recently on an auto body shop he owns in El Segundo. We have arrest and search warrants up the yin-yang. By the time we get there, the whole operation's been shut down and we walk into an empty facility – nothing left on the premises but a tire iron and a Pepsi can."

"I don't get it. What are you looking for?"
