The Last Precinct - Cornwell Patricia (лучшие книги читать онлайн TXT) 📗
Jaime Berger has been our uninvited Christmas guest. She has shaded my thoughts all afternoon. I can't stop thinking about one of the first things she asked when we met in my conference room. She wanted to know if anyone had profiled Chandonne's Richmond murders. She was so quick to bring that up and so clearly believes profiling is important. Certainly, she would have had someone profile Susan Pless's murder and I am increasingly suspicious that Benton very well may have known about that case.
I get up from the table. "Please be home," I say out loud to Berger, and I experience a growing sense of desperation as I dig in my satchel for her business card. On it is her home number and I call from Anna's kitchen where no one can hear what I say. A part of me is embarrassed. I am also frightened and mad. If I am wrong, I will sound foolish. If I am right, then she should have been more open with me, damn it, damn her.
"Hello?" A woman answers.
"Ms. Berger?" I say.
"Hold on." The person calls out, "Mom! For you!"
The minute Berger gets on the line I say, "What else don't I know about you? Because it's becoming patently clear that I don't know much."
"Oh, Jill." She must mean the person who answered the phone. "Actually, they're from Greg's first marriage. Two teenagers. And today I'd sell them to the first bidder. Hell, I'd pay someone to take them."
"No, you wouldn't!" Jill says in the background and laughs.
"Let me get to a quieter spot." Berger talks as she moves into some other area of wherever it is she lives with a husband and two children she has never mentioned to me, even after all the hours we spent together. My resentment simmers. "What's up, Kay?"
"Did you know Benton?" I ask her straight up.
Nothing.
"Are you there?" I speak again.
"I'm here," she says and her tone has gotten quiet and serious. "I'm thinking how best to answer you…"
"Why not start with the truth. For once."
"I've always told you the truth," she replies.
"That's ridiculous. I've heard even the best of you lie when you're trying to manipulate someone. Suggesting lie detectors, or the big needle truth serum to get people to 'fess up, and there's also such a thing as lying by omission. The whole truth. I demand it. For God's sake, did Benton have something to do with the Susan Pless case?"
"Yes," Berger replies. "Absolutely yes, Kay."
"Talk to me, Ms. Berger. I've just spent the entire afternoon going through letters and other weird things he received before he was murdered. They were processed in the post office located in Susan's neighborhood."
A pause. "I'd met Benton numerous times and my office has certainly availed itself of the services the behavioral science unit has to offer. Back then, at least. We actually have a forensic psychiatrist we use now, someone here in New York. I'd worked with Benton on other cases over the years, that's my point. And the minute I learned about Susan's murder and went to the scene, I called him and got him up here. We went through her apartment, just as you and I went through the Richmond crime scenes."
"Did he ever indicate to you that he was getting strange
mail and phone calls and other things? And that just possibly there was a connection between whoever was doing it and whoever murdered Susan Pless?"
"I see," is all she says.
"See? What the hell do you see?"
"I see you know," she answers me. "Question is, how?"
I tell her about the Tlip file. I inform her that it appears Benton had the documents checked for fingerprints and I am wondering who did that and where and what the results might have been. She has no idea but says we should run any latent prints through the Automated Fingerprint Identification System, known as AFIS. "There are postage stamps on the envelopes," I inform her. "He didn't remove them and he would have had to if he wanted them checked for DNA."
It has only been in recent years that DNA analysis has become sophisticated enough, because of PCR, to make it worthwhile to analyze saliva, and just maybe whoever affixed postage stamps to the envelopes did so by licking them. I am not sure that even Carrie would have known back then that licking a stamp might give up her identity to us. I would have known. Had Benton showed these letters to me, I would have recommended he have the stamps examined. Maybe we would have gotten results. Maybe he wouldn't be dead.
"Back then a lot of people, even those in law enforcement, just didn't think about things like that." Berger is still talking about the postage stamps. "Seems like all cops do these days is follow people for their coffee cups or sweaty towels, Kleenex, cigarette butts. Amazing."
1 have an incredible thought. What she is saying has brought to mind a case in England where a man was falsely accused of a burglary because of a cold hit on the Birmingham-based National DNA Database. The man's solicitor demanded a retest of the DNA recovered from the crime, this time using ten loci, or locations, instead of the standard six that had been used. Loci, or alleles, are simply specific locations on your genetic map. Some alleles are more common than others, so the less common they are and the more locations used, the better
your chances for a match_which isn't literally a match, but
rather a statistical probability that makes it almost impossible to believe the suspect didn't commit the crime. In the British case, the alleged burglar was excluded upon retesting with ad- ditional loci. There was a one-in-thirty-seven-million chance of a mismatch, and sure enough, it happened.
"When you tested the DNA from Susan's case, did you use STR?" I ask Berger.
STR is the newest technology in DNA profiling. All it means is we amplify the DNA with PCR and look at very discriminating repeated base pairs called Short Tandem Repeats. Typically, the requirement for DNA databases these days is that at least thirteen probes or loci be used, thus making it highly improbable that there will be any mismatches.
"I know our labs are very advanced," Berger is saying. "They've been doing PCR for years."
"It's all PCR unless the lab is still doing the old RFLP, which is very reliable but just takes forever," I reply. "In 1997, it was a matter of how many probes you used_or loci. Often in first screening of a sample, the lab may not do ten, thirteen or fifteen loci. That gets to be expensive. If only four loci were done in Susan's case, for example, you could come up with an unusual exception. I'm assuming the ME's office still has the extraction left in their freezer."
"What sort of bizarre exception?"
"If we're dealing with siblings. Brothers. And one left the seminal fluid and the other left the hair and saliva."
"But you tested Thomas's DNA, right? And it was similar to Jean-Baptiste's but not the same?" I can't believe it. Berger is getting agitated.
"We also did that just days ago with thirteen loci, not four or six," I reply. "I'm assuming the profiles had a lot of the same alleles, but also some different ones. The more probes you do, the more you come up with differences. Especially in closed populations. And when you think of the Chandonne family, theirs is probably a very closed population, people who have lived on Ile Saint-Louis for hundreds of years, probably married their own kind. In some cases, inbreeding_marrying cousins, which might also account for Jean-Baptiste Chandonne's congenital deformity. The more people inbreed, the more they up their chances for genetic glitches."
"We need to retest the seminal fluid from Susan's case," Berger decides.
"Your labs would do that anyway, since he's up on murder charges," I reply. "But you might want to encourage them to make it a priority."
"God, let's hope it doesn't turn out to be someone else," she says in frustration. "Jesus, that would be awful if the DNA doesn't match when they do the retest. Talk about really screwing up my case."
