The Killing Thing


by Janis Patterson

Perhaps it is the logical outcome of a disordered mind, but after several years of writing mysteries I tend to weaponize just about everything I see. My friends have become inured to this little quirk, but it sometimes does startle the people nearby.

I remember once going for a girls-only lunch at a trendy little cafe one of my girlfriends had heard about. The publicity had been wide-ranging, the food expensive but acceptable, the decor trendy - and very uncomfortable. Our table and chairs were made from metal tortured into shapes that few would believe were capable of supporting either food or human bodies. My friends either liked them or speculated if they were left over from the time of Torquemada. I speculated on using the chairs at least as a murder weapon, the table being too heavy to lift, saying that because of their strange configuration no one could ever describe them just from the wounds they would leave. The people at the next table left.

And it's not just me, either. When The Husband and I were staying at the dig house at the El Kab excavation in Egypt researching my book A Killing at El Kab the archaeologists and I were brainstorming about a murder weapon. I had almost decided on a broken chunk of statuary when the ceramologist (the pottery expert) had an idea and rushed out. He was back in a moment bearing one of the wickedest implements I ever did see. About a yard long, it was a heavy-duty caliper with a shaft of thick steel and a head vaguely resembling a pick-axe about 10 inches wide and an inch thick. It was perfect and because of the story and setting it was obviously the murder weapon (found covered with blood and lying next to the body) so I couldn't bring in the forensic 'What kind of implement could make this sort of wound?' trope... but it would have been so neat.

Once you become accustomed to looking at everyday objects through the lens of potential mayhem, the world indeed becomes a dangerous place. A gleaming sports trophy becomes a cudgel. A beautiful garden morphs into a buffet of potentially lethal plants. Sleek silk scarves make stylish but deadly garrotes.

My friends - mostly writers themselves but some not - have become accustomed to my whimsical forays into specialized slaughter and most find them amusing. I do tend to forget, though, that not everyone is privy to the basic innocence of my flights of fancy, viz the one time a group of us were sitting in a cafe (one with normal chairs, thank goodness) and I was speculating on the old trope of a piece of frozen meat being used as a blunt object and the ease of disposing of the murder weapon. My luncheon companions were becoming more and more uncomfortable, which I could not understand as we had had many similar conversations, until one of them revealed that the table behind me held a gaggle of uniformed police officers who were listening to our conversation with undisguised interest. Immediately our chatter switched to the intractability of our publishers, our current book release schedules, the necessity of finding good editors and other blatantly literary subjects. Luckily that day my luncheon expenses did not include bail. I even gave each officer one of my business cards as we left.

In real life most criminals are not smart - if they were, they wouldn't be criminals - and fiendish murderers with arcane methods and obscure weapons are very thin on the ground. Most real life murders are simple things - shot, strangled, stabbed, beaten; in fiction, though, we can let our imaginations soar. Our killers can use any of a million or more objects/methods to kill and get away with it until our intrepid sleuth tracks them down - and one of the glories of fiction is that the murderer is always brought to justice no matter how clever his killing.

Just be careful when you plot it in a public place.

How Much Explosive Is Enough?

Mystery writers always try to get their facts straight and keep their plots as realistic as possible. Writers who like the technical side of things, such as Tom Clancy, go to great lengths (too great for me) to explain exactly how things work. Is all that really necessary?

In my new novel, due out in October, I wanted the bad guy to rig a bomb that would damage a car but not seriously injure the passengers. I consulted a certified arson investigator for how to do it. We discussed several options and chose the one most popular among terrorists: ANFO, ammonium nitrate and fuel oil.

Used in large enough portions, it can demolish a major building, such as the Murrah Federal Building in Oklahoma City. But the typical IED (Improvised Explosive Device) used in Iraq and Afghanistan is much smaller. And the strength of the resultant blast depends upon the mixture. Put together by an inexperienced bomber, my source said, the bomb can be as powerful (or lack thereof) as you wish.

I have found the same thing true in dealing with forensics. Dr. Doug Lyle, the medical forensic guru, makes that point frequently in answering writers' questions. Within limits, you can make a blow to the head or a shot through the midsection do as much or as little damage as you desire. The same thing goes for time of death. Medical examiners can bracket a time frame, but this is no exact science. Things like ambient temperature or how long a body has been in water can make a big difference.

I try to set up the situation and let my experts give comments that indicate what I want to happen is plausible. Some explosives pro or weapons expert may challenge your premise, but if you've done your due dilligence, most readers will readily go along with you. I think they're more interested in the action and the suspense than in details best left to a technical manual or a medical textbook.

My advice is to tailor the scenario to what you need plotwise. Show it to somebody knowledgable in the field and get their comments. If it sounds good to them, go with it. Otherwise, make adjustments as needed. Just like a recipe. Put in a little more sugar or leave off the salt.

Steve McNair...a Classic Homicide by Chester Campbell


The past week in Nashville has been like a primer on police procedure for mystery writers. If you happened to glance away from all the Michael Jackson coverage for a bit, you may have seen where Steve McNair, the retired quarterback for the Tennessee Titans, a former NFL MVP, was murdered in an apartment near downtown in the wee hours on the 4th of July.

McNair had played for the Titans and its predecessor Houston Oilers his entire career, except for his last two seasons with the Baltimore Ravens. After retiring, he returned to live in Nashville with his wife and three children. He was a popular figure, constantly involved in working with kids and other charitable activities.

With such a high-profile figure, the Metro Nashville police went all out to investigate the case and bring it to a quick conclusion. A friend who rented the apartment with McNair found his body on a sofa early Saturday afternoon with two gunshots to the head and two to his chest. On the floor in front of him was a 20-year-old woman. She had been shot once in the head.

Homicide detectives, crime scene techs, a doctor from the Medical Examiner’s staff , and scores of cops converged on the scene. Crowds of fans who had been headed for a riverfront Independence Day celebration gathered behind the crime scene tape. Continuous live TV coverage showed evidence bags being brought out of the apartment.

At 3:30 p.m., Police Spokesman Don Aaron gave media the first official word that Steve McNair was dead, also a female not being identified until next of kin could be notified. When they moved her body, they found a semiautomatic pistol beneath her. Ballistic tests would be conducted at the Tennessee Bureau of Investigation crime lab.

Later that evening, police identified the woman as Sahel Kazemi, originally from Jacksonville, FL, whose mother came from Iran. Police had swarmed her suburban apartment and questioned neighbors. Sunday morning’s newspaper said the 36-year-old former quarterback had been dating her for several months, that she drove a Cadillac Escalade registered in both their names.

On Sunday afternoon, Spokesman Aaron gave another news conference. Autopsies had been completed, and McNair’s death was ruled a homicide. He said Kazemi’s death would not be classified until completion of further investigation.

Police reported on Monday that ballistics tests showed two shots to McNair’s chest and one to his head were fired from three feet away. The other shot to his temple was a contact wound. With the assistance of the ATF, they determined that Kazemi, a waitress at Opry Mills Mall, had purchased the gun Thursday night in the parking lot from a private individual.

At a news conference on Wednesday, Police Chief Ronal Serpas confirmed that Kazemi had shot McNair, probably while he was asleep, and committed suicide. Though McNair had apparently co-signed to allow her to purchase the Escalade, she was responsible for the payments. Conversations with friends and co-workers showed she felt her life was unraveling. She didn’t know how she could pay her bills, and she thought McNair had another girlfriend.

"We do believe there was evidence that she was spinning out of control," said Serpas.

The newspaper gave widespread coverage of the crime and the investigation, including detailed drawings of the crime scene, showing where the bodies were found. It was a classic case of gumshoe work questioning everybody who might have known anything and forensic testing to determine everything about the gun and its firing.

Thousands of fans flocked to memorial services yesterday. Crime writers are tasked with showing the effects of homicide on those around the victim. In this case, those most directly impacted were McNair’s widow and three young children in Nashville, plus an older son living with family in his hometown of Mount Olive, MS. Mechelle (Mrs.) McNair has chosen to remain totally private and has made no statement regarding her husband’s death.

Ironically, Steve McNair had opened a new restaurant, Gridiron9 (his old jersey number), near the Tennessee State University campus two weeks ago.

Another Conference to Consider

Morgan talking about Love is Murder in Chicago gave me the urge to write about the Public Safety Writer Association (PSWA) conference in Las Vegas in June.

http://www.publicsafetywriter.com

This conference is perfect for any mystery writer who writes about law enforcement, fires, investigations etc. The majority of members are active or retired law enforcement as that’s how the association began. However, they are a welcoming group of men and women who are wonderful about sharing information.

We also have several reasons for attending in the form of those coming:

1. Award winning author, Betty Webb. Not only will she be a luncheon speaker, she’ll be on several panels, and available to answer questions.

2. Forensic Expert, Steve Scarborough who works with the Las Vegas P.D. and the FBI.

3. Sara Cortez, award wining writer and editor, will tell us how to rev up our writing productivity.

4. Tim Dees, editor in chief of Law Officer.Com will be speaking on writing for the new media.

5. Sheila Lowe, court qualified forensic handwriting expert.

6. Dave Doust, retired captain Toronto Fire Department, to talk about fire fighting and arson.

7. Marilyn Olsen, editor; Billie Johnson, publisher; Becca Buckley, publisher will be on a panel telling us what they are looking for in submissions, what turns them off, and common errors made by authors.

We’re going to have panels on promotion, character building, and much, much more.

Anyone who signs up before May 1st who wants to be on a panel will get an assignment.

Remember, though, there’s a price break if you sign up before March 31.

Because this is a small conference, there is plenty of time for networking and asking the experts questions. It is also lots of fun–believe me, I’ve been to nearly everyone.

If you have a book to sell, bring copies. For every copy sold, PSWA gets 10%. There will also be a joint booksigning at Cheesecake and Crime in Henderson NV the afternoon of the last day of the conference for anyone who wants to be a part of it.

And, you might want to enter the writing contest. All the information is up on the website: http://www.publicsafetywriter.com

Hope to see some of you there.
