With the advent of television shows like CSI and others, those writing detective novels and crime scene investigators are under increased pressure to write details about crime detection. Which is not to say that CSI depicts in any way the actual steps that go into an investigation. I've been to many seminars put forth by forensic scientists and all roll their eyes at some of the more incredible plot lines in the television show. Likewise, many thrillers stretch the truth and the abilities of the tools out there for crime detection. In fact, there are some tools that simply don't exist, but have become embedded into the collective unconsciousness to such an extent that audiences believe they do.
I ran into this latter problem when writing my first, Running from the Devil. In that novel, my protagonist, Emma Caldridge, is on an airplane that's downed in the Colombian jungle. The paramilitary group that downed the plane arrange to take away the airplane's flight recorder and then bomb the remains, making it difficult for investigators to find the wreckage. Early manuscript readers, though, didn't believe that a plane's wreckage would be difficult to find. All seemed to think that a simple google earth search would reveal its exact location quickly.
Not so. In fact, there are hundreds of airplanes that crash and are never recovered or found. Most are in the Pacific Northwest in America, where the wooded areas and mountainous regions do not lend themselves to easy access, and others in countries with areas like the jungle, where dense foliage block any chance of finding it. In order to deal with the readers' lack of credulity about a fact that was actually true, I wrote in an official of the US organization in charge of finding downed planes and had him recite the actual statistics to an (equally incredulous) main character. Problem solved.
Luckily for most authors, there are now classes and workshops arranged by trusted sources that will teach you all you need to know about crime scene detection and give it to you straight. Not only are these classes informative, but they're a lot of fun. The trick to finding them is to scan the events pages of associations like the International Thriller Writers (ITW) or the museums in your area. I recently received a link from the Natural History Museum in London that is putting on a terrific forensic investigation evening on June 24th. In this evening, one can view a crime scene and learn how to determine date and time of death by insect collection (complete with maggots! Love these creatures and used them in Running from the Devil) as well as tips on how to identify sex and height of skeletal remains. I wish I lived in London. If I did, I'd attend this one for sure.
But wherever you live, if you're writing crime you'll eventually have to learn the basics of crime scene detection. Gruesome as it sounds, it's actually quite interesting.
Whatever you do, try your best to get it right or you will receive emails setting you straight. Just about every writer has had a mistake or two surface in their manuscripts and there are whole websites devoted to the continuity mistakes in movies. I guess that's reassuring. Even Hollywood gets it wrong sometimes.

Of Fallible Heroes and Infallible Technology
Editor's note: If The Outfit ever held a monthly dinner party with Chicago's most interesting people (and that's actually a really good idea) Lori Andrews might be the first person I'd invite. Lori is an attorney, law professor, historian, and novelist who advises government agencies around the world about genetic technologies. She also chaired the federal advisory committee on the legal and ethical implications of the Human Genome Project. In her terrific new thriller, Immunity, set during a provocative presidential race, geneticist Alexandra Blake and a rogue DEA agent track the killer behind a lethal new biotoxin. When she told me she was speaking a lot lately about the effectiveness of DNA testing, I asked her if she would guest blog here at The Outfit. If you want to hear more, Lori will read from the book tomorrow (Thursday, September 11) at 12:30 PM at the State Street Borders (150 N State) in Chicago. -kg

I’m one of the people least dazzled by technology of anyone I know. I don’t have an iPhone, iPod, or Blackberry. I still have a VCR. In my day job as a law professor, I undertake extensive government-funded studies of the effects of technologies on consumers and society. Will nanotechnologies lead to lung damage, like a new asbestos? Will use of sperm from the Nobel Prize sperm bank cause parents to reject their child if “E=mc2” isn’t the first thing out of his mouth?
But in my crime fiction, I fall into the same trap as CSI, Law and Order, and many other mystery writers who make it seem like crimes can be solved with the flip of a switch. In my latest book alone, a new date rape drug is identified by its chemical components, surveillance tapes finger the criminal, and a smack-talking computer that runs on DNA rather than the binary code helps solve the crime.
So I wonder: Why do we make our characters fallible and our technology infallible? And, is there anything we can do to change that?
We’ve made great strides making the city of Chicago a character in our books, pointing out its dark underside, as well as its heart-wrenchingly beautiful traits. But other than in a few cases (Kevin’s book dealing with cloning, Cast of Shadows, for example), we don’t treat technology as a character, subjecting it to our scrutiny and cynicism.
But maybe it’s time we started. There’s certainly plenty of material.
DNA forensics is not as reliable as most people think. We each have a 3 billion-character long string of DNA, which includes within it around 25,000 genes. If DNA forensics tested all 25,000 genes, then it would be a great way to identify people. But it only tests 13 snippets of DNA, called loci (and it used to test only 9). A variety of people might have similar genetic profiles when only 9 or 13 segments are looked at-–if they are relatives, for example, or if they belong to the same ethnic group, like the Native Americans in my latest book.
In July, the Los Angeles Times caused a panic in the forensic community with its article, The Verdict is Out on DNA Profiles. The FBI claimed that a match between a crime scene sample and DNA in CODIS had the odds of one in 113 billion. But a technician working in the Arizona Department of Public Safety Crime Laboratory, Kathryn Troyer, found 122 men in the Arizona database that matched at 9 loci, 20 at 10 loci, one match at 11 loci, and one match at 12 loci. Laboratory workers from other states claimed to have seen similar matches in their own crime labs.
In the wake of the Troyer discovery, criminal defendants have tried to compel crime labs to disclose how many other people in the forensic databases have DNA matching theirs at a significant number of loci. The FBI’s response to such court orders has been to intimidate labs by threatening to take away their National DNA Index System privileges if they comply with the request. In essence, the FBI is trying to prevent defendants from learning if there are flaws in the technology that is being used to convict them.
Plus, DNA forensics can be thrown off by human error and technological shortcomings. In one study, 45 laboratories were asked whether particular DNA samples matched. The labs were presumably using their best techniques since they knew they were being studied. Yet, in the 223 tests, matches were identified in 18 cases where they did not exist. Mistakes do occur in forensic DNA testing, yet jurors are often told that errors are nearly impossible. This means they might be convicting innocent people—or letting guilty ones off the hook.
The fallibility of technology could be an exciting subplot in a crime fiction. I think we shy away from it because it is hard to explain science. And the glitz of gadgets, the seduction of technology, is just too strong. We ooh and aah when Q in the James Bond movies unveils a pen that converts into a lethal stun gun or a car that can fire a missile. And if the right technology is not at hand, we pin our hopes on a hero like MacGyver who can fashion his own.

Gunfights, Interrogations, and More
by Libby Hellmann
Did you know that most gunfights in law enforcement last 3 seconds or less? That police officers hit their targets only 20 per cent of the time? That blood never oozes from a dead body? That there are over 15 ways to tell if a person is lying?

I learned all the above -- and more -- at a stellar conference last weekend in St. Louis. The conference was called “Forensic U” and it was sponsored by Sisters in Crime. It was an incredible opportunity for crime writers – at any stage of their career -- to immerse themselves in subjects that, to the uninitiated, can seem arcane, even gruesome. But to us, it’s research, and it’s all fascinating. At least to me.
The fact that it was sponsored by Sisters in Crime, an organization founded twenty years ago by the Outfit’s own Sara Paretsky, and that both Barb D’Amato and I served as president of, made it special. As far as I know, SINC is the only writers’ organization to offer this kind of information specifically to the crime fiction community. Sure, there are conferences on writing, publishing, and promoting. There's also that NRA/firearms conference in Las Vegas. But I’m not aware of any writers' programs specifically focused on tradecraft. Kudos to Joanna Slan and Michelle Becker for co-chairing the event.
The curriculum was impressive and just this side of overwhelming. There were workshops on DNA, forensic anthropology, pathology, police procedure, toxicology, interviews and interrogations, blood spatter, warrants and searches… and more. (In fact, here’s a link to the agenda.) A judge spoke to us about CSI and how it’s affected jurors, a pathologist took us through a death investigation that turned out to be a homicide, and the head of the St. Louis crime lab told us how they’re structured.
Jan Burke talked to us about the history of forensics and the Crime Lab Project; Doug Lyle talked about evidence, poisons, and blood spatter; former cop Lee Lofland talked about undercover tactics and police procedure; and Rick McMahan talked about the use of force, firearms, street fighting, self-defense (photo by Bonnie Cardone), and the ATF. Happily, some, but not enough, of the classes were offered more than once, so if you missed one, you could catch it again. 
All of the workshops were conducted in layman’s language, but I never felt I was being patronized. In fact, I was surprised by how many attendees weren’t writers. Apparently, there is a hunger out there, from readers as well as writers, for accuracy and information about forensics -- beyond what's available in the media and on TV.
Which prompted a question: what do you want to know about forensics? Do you want to know how DNA is analyzed? What happens to a bullet from the time it’s loaded in a gun until it hits a target? How an autopsy reveals clues to a person’s death? Which poisons are virtually undetectable?
And here’s another question: what would it take for you to come to a conference like this? I’m pretty sure SINC will repeat the conference sometime in the next two years. Is there anything you feel is a must?
Btw, the conference included a trip to the gun range. I shot a .22 and a Glock 9 millimeter. But only two rounds. I need more. I did apply for my FOID card last week. Assuming I pass the background check, it should arrive in a month or so.
To be continued…
