F – Fantasy and Fiction

Fantasy is hardly an escape from reality. It’s a way of understanding it.
Lloyd Alexander

Stories are fantasy, but in this fantasy we are free to explore life, truths, and our own experiences. We can try on different roles, live vicariously in different eras, and struggle with different villains.

Stories are so important to us that we set them down in books, then in plays, movies, and television. From early childhood we were enraptured with them and made up our own in play.

I don’t know if it’s metaphor or vicariously living with the protagonist or the natural rise and fall in tension. I’m not sure if it’s anticipation, the wonder of “what’s next,” or the need to tell our own stories  until we’ve fully accepted them.

Stories teach, warn, comfort, thrill, amuse, and challenge. Fables, urban legends, adventure—stories both entertain us and resonate in us. I recognize it. I know it. I can’t say I understand it. From the first gathering of tribes, there have been stories. How many story lovers have written a thesis or dissertation on the humanity of stories?  Not enough, I think.

Stories communicate ideas, beliefs, the state of society in all its horror and splendor. I can’t imagine a life without stories, can you? We tell them at work, with friends, to ourselves.  We relate the events of our lives with a beginning, middle, and end.

To listen to and tell stories is to be human.

Why do you think humans developed stories? What is it about stories that binds us?

Crime Scenes for Writers: DNA and Biologics

Here we are at the last post in the series. Time flies, right?

Most of us are familiar with DNA, the individual blueprint for each of us. DNA testing has come so incredibly far in the last twenty years, almost to the point that we expect DNA to answer most if not all of our questions. That makes CAN an interesting place for writers to stymie the investigator (and the reader).

DNA is a powerful tool, yes, but not without exception in the field of criminal investigation. Consider the following scenario:

The Case of Sally Simms

Sally lives alone in her apartment. In the last three days, she’s had new appliances installed, new cable run for the internet, her boyfriend has visited several times, her sister and her sister’s boyfriend were over for dinner, and she had a coworker over for coffee.

Sally is found dead on the floor of her hallway. The science teams go through her apartment collecting everything they can find and Sally goes off to the autopsy table. The police begin with the list of possible suspects: Sally’s boyfriend, sister, sister’s boyfriend, the appliance installer, the cable installer, and the coworker.

DNA is everywhere. Each person in the apartment left their DNA behind. If Sally’s cause of death was a blow to the head, DNA is not helpful unless the object is found and DNA is recovered from parts of the object only the killer would have touched. Your police detective must turn to other investigative means.

During autopsy, should DNA from seminal fluid be found to match both the boyfriend and the sister’s boyfriend, Sally’s sister is going to want an explanation, but it doesn’t make either of them the killer, especially as Sally was dressed and in the hallway. Scrapings from under Sally’s fingernails might yield DNA, but if the suspect shows a scratch healed beyond the time frame of her murder, it might just mean Sally didn’t scrub her hands or under her nails.

Plausible DNA

Now, in most cases, DNA is eliminated because it has a plausible reason for being where it is. If other lines of investigation develop a suspect, DNA might support it, but not be conclusive. I don’t know about you, but I get a perverse kick out of writing crime stories in which DNA is not a major part of evidence, just because I can and I like the unexpected.

DNA is absolutely helpful in the case of serial crimes such as rape and murder, since unknown DNA from crime scenes is entered into and checked against CODIS, the Combined DNA Index. Once a suspect’s DNA is available for match, he or she could be connected to a series of crimes.

DNA can be collected from almost any surface and from almost any body fluid. Hair won’t give DNA but the hair root (if torn out) can. Naturally shed skin won’t give you much, but scrape your arm across an abrasive surface and it’s possible.  And when stranger DNA is present from a person who has no explanation for being at the location, good chances are you have your criminal.


But there’s more. In recent years, we’ve made serious headway into biologics which, in addition to DNA and fingerprints, also includes palm prints, palm vein patterns, facial recognition, ear recognition (mostly in Europe still), Iris patterns, retina recognition, hand geometry, and odor or scent.

What was partially developed for security has become a database of biometric information. The Department of Homeland Security has IDENT, which includes biometric and associated biographic information. The Department of Defense has ABIS, the Automated Biometric Information System. CODIS, which also includes the National DNA Index, will, I suspect, branch into biometrics if it hasn’t already.

We already use biometrics to solve a crime such as Sally’s. Even if the killer wore gloves, should a lamp base or makeshift weapon turn up in good condition, it would be possible to match the size and shape of the hand to the person who wielded it. If her building has solid security camera coverage, facial recognition might identify or confirm a suspect entering and leaving the building near the time of the murder.

The Future is (Mostly) Now

The possibilities are as numerous as the writer’s imagined scenarios.  Consider shifting the story ten years into the future, and the writer could have a lot of fun with solving Sally’s murder.

I hope this series has been helpful. I’ve been working on a series titled Body of Evidence, but I’m not certain you would be interested in reading about the evidence a body can yield after death. Please comment below if you’d like me to post the Body of Evidence series. Though it’s not written in graphic language, some of the subject matter may prove uncomfortable for some readers.

Has anything in this series changed the way you look at criminal investigation from a storyteller’s point of view?

Crime Scenes for Writers: Trace Evidence

Using trace evidence to solve the crime in your story is a great way to delay the payoff and finger the guilty party. I’ve given a list of the most common types of trace evidence and a brief description of each, though they could all be a post on their own.


Clothing, leather, car interiors, carpet, and rope can all provide fibers for the investigators to discover and trace. The Mass Spectrometer is one tool used to identify the chemical makeup of a fiber. For example, carpet manufacturers’ and some fabric manufacturers’ product chemical signatures are in a database or researchable. This could narrow down the year, make, and model in the case of a car, or distribution information in the case of carpet and other fibers.  The most common use of fibers, however, is to match them from the crime scene to the suspect or the suspect’s environment.


Plants have DNA just like we do, so seeds or pods can often be linked to a specific plant. This might tell investigators where the suspect or the victim spent time as plants are often geographically specific.  Another use would be, for example, the discovery of seed pods in the suspect’s vehicle and matching them to the seed pods under the victim.


Larvae and living insects aren’t considered trace evidence, but webs, egg casings, insect parts, and evidence of bites or stings can yield evidence as to location, length of time the victim was at the dump site or crime scene, and even season if the crime occurred well before discover.


Humans and animals shed hair all the time, making hair one of the most common types of trace evidence. Once a suspect is identified, strands of hair can be matched. If the hair is pulled from the root, it may contain enough biological material to get a DNA sample. Pet hair found on or near the victim and also in the suspect’s environment (matched to a specific animal) can also boost the prosecutor’s case.


Fluids include bodily secretions, of course, but other fluids include tree sap, cleaning products, chemicals, beverages, oil and gas, and water (pond water, ocean water, etc.). While these give information about the crime, I’ve always thought it would be interesting to use a fluid as the breakthrough piece of evidence. Something totally out of place would stump investigators and extend the tension of the story.


I like this sort of evidence, and I’m intrigued about how to use particulates to good effect in a murder mystery. Here are four:

  • Paint: In addition to binding chemicals, paint often includes a mineral or metal as a color ingredient. These can be matched to known paint products, vehicles, and other elements of locations. In the world of crime shows, I’ve seen it most often used to identify a vehicle, but wouldn’t it be fun to connect it to an artist’s studio or the statue in the town square?
  • Soil: The great thing about soil is that it’s fairly localized depending on the particulates. Sandy, clay-based, loam, fertilized, mineral-rich . . . all give the investigators information they might not otherwise discover.
  • Metals: Paint, vehicles, tools, clothing fasteners, soil, weapons, and much more, contain metals that can be traced and/or matched to the crime scene, dump site, or suspect’s environment. We see it used most often to identify, again, a vehicle, but flecks of gold might indicate a manufacturing process, and copper shavings might point to the plumbing or construction industry.

Trace evidence offers so many opportunities for the writer and suspense for the reader. It’s by far my favorite type of evidence to include in stories.

The last post in the series is DNA and Biologics. See you then!

How many ways can you think of to stump the reader and detective with trace evidence?

Crime Scenes for Writers: Reading the Scene

Writers and readers should never underestimate a talented investigator’s ability to read a crime scene. On the other hand, they can only “read” what exists. I should note as well that in large departments, detectives or investigators may not arrive at the scene for several hours or even before the body is removed.

Here’s just a short list of things they might look for at the scene of a murder:

  • Signs of forced entry
  • Signs of struggle
  • Activities of the victim before the crime
  • Activities of the perpetrator both before and after the crime
  • Location, position, and state of the body
  • Missing, added, and out-of-place objects
  • Bullet trajectory
  • Blood location, trajectory, and characteristics
  • Observation of environmental conditions
  • Elements of overkill
  • Evidence of murder weapon

In addition to the scene itself, investigators gather information such as the last time the victim was seen or spoken to, the last time mail was taken in, anything seen or heard by neighbors or passersby, and the habits of the victim. This information is merged with the information at the crime scene to form a more complete picture. The two sets of information need to be compared and discrepancies reconciled.

The initial theory of what occurred may suggest looking for particular types of evidence or locations to search for fingerprints, DNA, shell casings, stray bullets, and possible trace evidence.

The activities of the perpetrator before and after the crime, such as attempts to clean up the scene, him/herself, posing the body, staging, preparing or eating food or lingering at the scene, and any signs of odd behavior all help police develop information about their suspect, both physically and psychologically.  These details are critical to any investigation and provide the framework that police hope will be fleshed out with forensics. This is also a great place to give your reader an obscure clue or a red herring.

The location of the crime and the lifestyle of the victim also give police useable information. A murder that occurs in a suburban home is quite different from one that occurs in a downtown alley in terms of what evidence is visible to the naked eye (and how much evidence must be sifted through and ruled out).

Careful observation and recording of all elements of the crime scene are so important that technology was developed to “map” the scene with a laser in order to recreate it digitally. However, smaller police departments still need to rely on dozens of photos, measurements, sketches, and written notes.

Some investigators will return to the crime scene several times (or more commonly, the photos, reconstruction, or notes). The more experienced and intuitive the investigator is, the more this is helpful. Regardless, it is one of the tenets of investigation that, when you get stuck, you once again begin at the beginning, examining the scene. ViCAP (Violent Criminal Apprehension System), though it has some issues,  is also an option for investigators if they suspect the perpetrator has committed similar crimes or they run out of leads.

It is only when there is so little obvious information at the crime scene that cases might hinge purely on what can be uncovered by forensic science. Developing a suspect is more difficult if the victim has been left somewhere other than where he or she was murdered (at a “dump site”), but it’s still possible to gain insight and clues.

Forensics may uncover leads not visible to the naked eye, but the fact remains that the impressions of the investigators at the scene remains the base component of any file. It is also vital information for behavior analysis, or profiling.

Next time, we’ll look at one of the oldest forensic techniques: Fingerprints.

Does your investigative character have special rituals or routines when entering a crime scene?

WTF Photo Prompts

This photo sums up the title of this post. My apologies to those who are squeamish. Really, WTF? How on earth did this happen? Did anybody see it? What happens next? Where is this located? What’s the story?

I’ve seen deer get up and walk away from worse. Do you have a crazy wild animal anecdote to inspire a shory?
