From HOWDUNNIT:FORENSICS:

GETTING RID OF THE BODY 

Some criminals attempt to destroy corpses, the primary pieces of evidence in homicides. They think that if the police never find the body, they can’t be convicted. This isn’t true, since convictions have in many cases been obtained when no body is found. And destroying a body is no easy task. 

Fire seems to be the favorite tool for this effort. Fortunately, this is essentially never successful. Short of a crematorium, it is nearly impossible to create a fire that burns hot enough or long enough to destroy a human corpse. Cremation uses temperatures of around 1,500oF for two hours or more and still bone fragments and teeth survive. A torched building would rarely reach these temperatures and would not burn for this long. The body inside may be severely charred on the surface, but the inner tissues and internal organs are often very well preserved. 

Another favorite is quicklime. Murderers use this because they have seen it in the movies and because they don’t typically have degrees in chemistry. If they did, they might think twice about this one. Not that quicklime won’t destroy a corpse; it just takes a long time and a lot of the chemical. Most killers who use this method simply dump some on the corpse and bury it, thinking the lime will do its work and nothing will remain. Quicklime is calcium oxide. When it contacts water, as it often does in burial sites, it reacts with the water to make calcium hydroxide, also known as slaked lime. This corrosive material may damage the corpse, but the heat produced from this activity will kill many of the putrefying bacteria and dehydrate the body. This conspires to prevent decay and promote mummification. Thus, the use of quicklime may actually help preserve the body. 

Acids are also used in this regard, and once again the criminal hopes the acid will completely dissolve the body. Serial killer Jeffrey Dahmer tried this with little success. Indeed, powerful acids such as hydrochloric acid (HCl), sulfuric acid (H2SO4), and
chlorosulfuric acid (HClSO3) can destroy a corpse, bones and all. If enough acid is used over a sufficient period of time, that is. But this is not only difficult but also extremely hazardous. The acids will indeed destroy the corpse, but they will also “eat” the tub the body is in and chew up the plumbing. Acid fumes will peel the wallpaper and burn the perpetrator’s skin, eyes, and lungs. 

FORENSIC CASE FILES: THE ACID BATH MURDERER 

John George Haigh came to the English public’s attention in the 1940s when he confessed to not only multiple murders, but also to drinking his victims’ blood and destroying their corpses with acid. He seemed to favor sulfuric acid, which he kept in a vat in his workshop. He took the victims’ money and, through forgery, their property and businesses, and then basically laughed at the police as he admitted to the killings, believing they could not prosecute him without a corpse. He was wrong. He was convicted through forensic evidence and was hanged at Wandsworth Prison on August 10, 1949. 

So, whether it’s Mother Nature or the work of the perpetrator, something almost always remains for the ME and the other forensic scientist to work with. It may be an intact body, a partially destroyed corpse, or a single bone, but it will give them something to use in identification. Let’s take a look at how they do this—first with a body and then with only skeletal remains

BODY LOCATION 

With the exception of some photographic comparisons, all these forensic identification techniques require a corpse or skeletal remains. No body, nothing to work with. Often a discovered body is what instigates this identification process. But sometimes, investigators know a homicide has occurred, or has likely occurred, but they can’t find the corpse. The Laci Peterson case is an example. When Laci, who was eight months pregnant at the time, went missing on Christmas Eve 2002, in Modesto, California, it was not long before it became obvious that she had been murdered. Authorities launched a search of her neighborhood and the bay where her husband, Scott, had been fishing. In April 2003, the bodies of Laci and her unborn son Conner washed up on shore in San Francisco Bay. Scott Peterson was later convicted of the double murder. 

In homicides, finding and examining the corpse is critical. Searchers use a number of low- and high-tech location methods. All evidence is used to narrow the search area, including the victim’s work and leisure habits and witness statements. The victim may work several miles from home, so searching along this route would be undertaken. Maybe he frequently ran or walked in a nearby wooded area. Or maybe the suspect’s vehicle was spotted or some of the victim’s clothing was found in a remote area. These bits of information can greatly focus the search. 

One basic rule is to “look downhill” for a burial site. Let’s say it is believed that the body in question was buried near a remote roadway. In the area, the terrain rises above the road on one side and falls away on the other. Search downhill. Why? It is much easier to carry a body downhill than up. It’s just that simple. 

Once the area of search has been defined, a systematic approach to cover- ing the area should be followed. Freshly turned dirt, trenches, elevations or depressions in the terrain may be helpful. Fresh graves tend to be elevated above the surrounding area, while older ones may be depressed. This is due to settling of the soil, decay of the body, and collapse of the skeleton. Interestingly, the depth of the depression is greater if the body is deeply buried. This is likely due to the larger amount of turned dirt, which is subject to a greater degree of settling. Another factor could be that in deeper graves, the increased weight of the dirt over the corpse causes earlier and more complete skeletal collapse. 

Tracking dogs, if provided with an article of the victim’s clothing, may be able to follow a scent trail to the burial site. Specially trained cadaver dogs search for the scent of decaying flesh. They can often locate bodies in shallow graves or in water. Deeper graves may present problems.

Another important clue may come from changes in the vegetation over the gravesite. The turning of the soil in the digging process and the presence of the body change the soil conditions in the area over the grave. Changes in compaction, moisture, aeration, and temperature may attract plant species that differ from those around the grave. Or, the plants typical for the area may be present but the changed soil conditions may increase the thickness and richness of their growth. This may be visible, particularly from the air. 

Aerial reconnaissance and photography can be coupled with thermal imaging. Freshly turned dirt loses heat faster than normally compacted soil; it appears “colder” by such a device. Alternatively, a decaying body releases heat, which may reveal a measurable difference when compared to the surrounding area. So, the thermal images are inspected for either cold or warm spots, and these areas are then subjected to a more aggressive search. 

If a suspect area such as a mound or depression is found, special devices that locate sources of heat and nitrogen, both byproducts of the decay process, or that measure changes in the physical properties of the soil, may be employed. Ground-penetrating radar can “see” into the ground and often locate a buried body. Measurement of the electrical conductivity may prove helpful— a buried body often adds moisture to the soil, and the moisture increases the soil’s electrical conductivity. Two metal probes are placed in the soil, and an electrical current is passed between them and measured. Changes in this current may indicate where the body is buried. 

Magnetic devices may also be employed. A simple metal detector may locate the victim’s jewelry or belt buckle. 

A special device called a magnetometer, which measures the magnetic properties of soil, can also be helpful. Soil contains small amounts of iron, so it possesses a low level of magnetic reaction. Since the area where the body is buried has proportionally less soil (the corpse takes up space), it will exhibit a lower level of magnetic reactivity. The magnetometer is passed above the soil and locates any areas that have low magnetic reactivity.

ABO Blood Type System

From FORENSICS FOR DUMMIES

By simply typing the blood at a crime scene, investigators narrow their suspect list and completely exonerate some suspects by using the population distribution information for the four ABO blood types. 

Population Distribution of ABO Blood Types

O: 43%

A: 42%

B: 12%

AB: 3%

Besides determining the ABO type, serologists are able to further individualize blood samples. RBCs contain more proteins, enzymes, and antigens than those used in the ABO classification system. These include antigens with such catchy names as Duffy, Kell, and Kidd and intracellular enzymes such as adenylate kinase, erythrocyte acid phosphatase, and the very useful phosphoglucomutase (PGM).

PGM is an enzyme that appears in many different forms, or isoenzymes, and at least ten of them are fairly common. Regardless of ABO type, a particular individual can have any combination of the isoenzymes of PGM. The ME and the serologist use that fact to further narrow the list of suspects for further DNA analyses and confirmation that they were capable of leaving a particular bloodstain.

For example, say that a stain is Type AB and has PGM 2. The ME knows the AB blood type is found in only 3 percent (see Table 14‐1) of the population, and PGM 2 is found in only 6 percent of people. Because these two factors are inherited independently, the probability of a particular individual being Type AB, PGM 2 is only 0.18 percent or less than 2 per 1,000. 

If the police find blood at the scene that matches the blood of a suspect who has Type AB, PGM 2 blood, the probability that that suspect is not the perpetrator is 2 in 1,000. Although not perfect, those odds still are much better than a coin toss. 

Testing for Paternity 

You inherit your blood type from your parents. For that reason, a serologist can assess paternity in many cases. The crime lab is often involved in paternity testing because paternity may be a critical component in determining child support, custody, and visitation. It also may play an important role in crimes and civil proceedings that involve kidnappings, insurance fraud, and inheritance conflicts. 

Inheriting your blood type 

ABO blood types, or phenotypes, come in only four varieties: A, B, AB, and O. But, for some blood types two genotypes, or gene pairings, are possible. A phenotype is what something looks like (in this case the ABO blood type), while the genotype is the underlying genetic pattern. We receive our ABO genes from our parents, one from Dad and one from Mom. 

The important thing to know in this system is that A and B genes are co-dominant (equally dominant), while the O gene is recessive. So someone who receives an A gene from one parent and an O gene from the other has Type A blood, but not Type O, because the A gene is dominant. 

Determining Possible Genotypes from Phenotypes 

Type A: AA or AO

Type B: BB or BO

Type AB: AB

Type O: OO

People with Type O blood must have an OO genotype. They can have neither an A nor a B gene because having one or the other dominates the O gene and produces either Type A or Type B blood. 

A person with Type A blood can either receive an A gene from each parent and thus have an AA genotype or an A gene from one parent and an O gene from the other for an AO genotype. Remember, A is dominant, so when it is paired with the recessive O gene, the A gene determines blood type. People with the AA and AO genotypes both have Type A blood, but genetically speaking, they’re different. 

Type A parents who have AA genotypes can provide only A genes to their offspring, because all their eggs or sperm have an A gene. But Type A parents who have AO genotypes can provide either an A gene or an O gene to their offspring, because half their eggs or sperm have an A gene, and the other half have an O gene. When both parents are Type A, several possibilities exist for the genotype their offspring will have.

In each of the scenarios presented in Figure 14‐1, the child’s blood type is Type A, except when both parents donate an O gene. In the latter case, the child’s genotype and blood type (phenotype) respectively are OO and Type O. These parents can’t have any offspring who have Type B phenotype or BB, BO, or AB genotypes, because neither parent has a B gene to donate. 

Determining Fatherhood

Blood typing can exclude paternity but cannot absolutely verify it. For example, a man with Type AB blood can’t father a child with Type O blood. So if a child has Type O blood, all men with the Type AB are ruled out as the child’s father. A man with Type A (genotypes AA or AO) blood can be the father, but only if he has an AO genotype. Men who have AA genotypes also are excluded. Men with the AO genotype, however, can’t be ruled out at this point.

Guest Blogger: Dr. Katherine Ramsland: The Unique Allure of the Scene of a Crime

 

Visits to murder sites reveal more than mere curiosity.

There’s been a lot of attention lately on why people love true crime. I can recall when publishers considered the subject a waste of their time. Suddenly, it’s big business. Psychologists are weighing in, mostly guessing at the motivation. I’ve seen no representative studies on the topic, but I’ve been among true crime fans for more than two decades, so I can speak anecdotally.

I don’t think it’s because, as one expert put it, people are fascinated with evil. That’s just a superficial sense of something deeper. Crime is specific. The fascination is not with evil itself but with the formation of the motivation to harm and the development of a mind that can think up twisted and cruel treatment of others.

Extreme behavior is difficult to fathom, especially the cold-blooded kind, and TC fans want to try to understand. Women, especially, are attuned to motives and to victim predicaments. They enjoy feeling compassion and empathy. Sometimes, they identify with the woman who snaps or plans revenge.

The intensity of emotion typically involved in murder, whether a domestic homicide or a mass killing, draws us out of everyday dullness. We focus. There’s a heightened sense of suspense and thrill. For some, it also involves the cycle of being scared by what happens in the story and then feeling safe.

Another expert said that the current interest in true crime is driven by the 24/7 news cycle. It does play a part. When news anchors hype crimes with over-the-top coverage, the networks that broadcast “all crime all the time” will scoop up the story. The media certainly contributes, but possibly only to stoke a spark that is already present. The news covers other areas of life every day that don’t become obsessions; true crime stands out. So, it’s not just about 24/7 news.

We get closer to the embrace of TC when we study the core narratives that turn up in one presentation after another. Most TC books, documentaries, and TV series build up to the same resolution. They present the lure of a puzzle, provide guidelines for protection and preparation, and resolve tension by showing how the perpetrator was caught (often by being outsmarted) and punished. Thus, TC narratives play on our desires for catharsis, safety and closure. We enter through the intrigue of mystery and exit feeling better, sometimes even smarter.

Perhaps there’s an evolutionary benefit, as some psychologists suggest, in terms of making us pay better attention to dangers in our environment. Whenever I teach a course on serial killers, multiple students tell me they now lock their doors and notice people around them. But I don’t think this fully explains the fad. It’s true that TC has always fascinated, but recently it’s become much more of a cultural obsession. There’s an emotional payoff that’s become a collective pursuit.

True crime lets us experience anxiety and fear in a controlled way. It’s not happening to us, but we can work our way through it. People gawk at terrible things sometimes for reassurance. We can let ourselves imagine monsters coming for us because they can’t really get us. We purge fear within a frame of safety. As the TC community grows, we can share our “guilty pleasure” and form groups that reinforce the payoff.

Although a small sliver of the TC fan community seeks the bloodiest, most disgusting images they can find, most immerse themselves, then and get out. They’re interested in human behavior, not a gore-fest.

This brings us to visiting actual murder sites. I once wrote a travel column about tourable murder sites and I’m currently creating a presentation about “Dark Tourism.” This involves looking for sites that people visit who want to see where a murder happened: The steps of Gianni Versace’s former South Beach home, for example, where Andrew Cunanan gunned him down, or the clock tower at the University of Texas at Austin’s campus from which Charles Whitman picked off targets in August 1966 until police killed him.

It may sound morbid, but getting close to the intense energy of disturbing events initially evokes a rush. The energy of madness, anger, lust, or jealousy seems to pervade the place. People linger outside the “Amityville Horror” house where Roy Defeo shot his entire family, the home in Ohio where Jeffrey Dahmer killed and buried his first victim, and the former boarding house where kindly Dorothy Puente murdered men for their welfare checks and buried them in her garden.

In some cases, there are tours. In London’s Whitechapel neighborhood, expert guides will take you to where Jack the Ripper allegedly killed at least five women in 1888. In Wisconsin, there’s a Jeffrey Dahmer tour, and in Los Angeles, you can take any number of tours to infamous places, like where the Black Dahlia’s body (parts) were placed, where Nicole Brown Simpson was killed, or where the Hillside Stranglers dumped their victims. In Chicago, there’s an H. H. Homes tour (“The Devil in the White City”), although his actual murder castle is long gone.

You can see Lizzie Borden’s infamous former house just by walking by it in Fall River, Massachusetts, although it’s worth taking the tour inside – or getting a room. You can also see the JonBenet Ramsey murder house and the house in Villisca, Iowa, where a sensational mass murder occurred a century ago. Now it’s a museum. Another museum graces the Jesse James Farm in Kearney, MO, as well as the Sarah Winchester House in San Jose, California. Frank Lloyd Wright’s tourable Wisconsin estate, Taliesin, was the scene of a massacre in 1914.

Savannah, Georgia, hosts several genteel homes in which murder occurred. The most famous is Jim Williams’ Mercer House, the setting for Midnight in the Garden of Good and Evil, which is open to tours. Then, there’s the murder-suicide in poet Conrad Aiken’s former home. Many of the ghost tours in the historic area describe criminal incidents, but Savannah has also added a few TC tours.

New York, New Orleans, Chicago, San Francisco – practically any large city has a crime history that lends itself to tours or museums. People go to experience the details of the horrendous acts by getting as close as possible to the physical setting.

I said above that, initially, there’s a rush. This often gives way to reflection and sadness. At the sites, people learn more about the victims than they typically know. When I stood in front of the homes where Dennis “BTK” Rader killed his victims, I thought a lot more about them than about him. Whatever one might have learned from offender-centered media, the sites themselves usually humanize the victims and invite us to imagine their plight. It’s about lore, not gore.

DNA Comparisons in 12 Seconds?

 

Though there are DNA techniques such as Familial and Phenotypical analyses that can narrow the search for a suspect, in the end, DNA is most useful if it can be profiled and matched against another sample. Databases play a large role in such comparisons when an unknown crime scene sample is obtained. Even if no suspect is on the radar, a “hit” on a database comparison can lead investigators down the right path. But these take time. And if a killer is “out there,” time is often critical. What if investigators could obtain a sample at the scene and compare it against 20 million databases sample in only a few seconds? That would be amazing. But guess what? With the FastID algorithm, it seems to be possible.

Could be a game changer for law enforcement.

“Good fences make good neighbors”—Robert Frost, “Mending Wall” 

I suspect Ryan Felton Sauter’s neighbor, Keith Monroe, would agree.

People commit murder for a host of reasons. Things like financial gain, revenge, lust, anger, to cover another crime, and many other motives. It seems that these motives can even include a dispute with the dude who parked his RV next to yours.

All sorts of weapons are used for committing murder. Guns, knives, poisons, explosives, ligatures, drownings, and gentle pushes off buildings or cliffs. Oh, don’t forget rattlesnakes. This seems to be what Mr. Sauter decided to employ. Simply slipping the reptile into his neighbors RV might not work since rattlesnakes make that buzzing noise to warn people away. So, wouldn’t it be best to simply remove the rattle. And I guess the best way for that is to bite it off.

You simply can’t make this stuff up.

But snakebites are not always the result of some criminal activity. In fact, they rarely are. Most snakebites occur accidentally. Hunters and hikers know this all too well. As a kid growing up in Alabama, and stomping around in the woods on a daily basis, I knew snakes well. I knew which ones to avoid and which ones were harmless. A black racer was scary and fast, but harmless. Stumble on a rattlesnake or a copperhead and that’s a different story. And until you’ve seen a water moccasin, or as we call them cottonmouth, you haven’t seen an evil looking serpent. These guys are thick, dark, and prehistoric looking. And very dangerous. Yes, they can bite you in the water. So before you jump into that swimming hole deep in the woods, you better make some noise and shake up the water runoff any cottonmouth might be around.

But other people are bitten while they are handling snakes. I don’t mean just biologist or herpetologist, those that study these creatures, but also those who use them in religious ceremonies. You might think that snake handling is a thing of the past and something that is only found in the South, but that’s not true. There are still several snake handling churches from coast-to-coast. Even though in many locations snake owning and handling is not legal, the laws get shaky when it’s under the guise of religion.

Their justifications come from Mark 16:17-18

“And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.”

Snake handling in churches is often traced back to 1910 when George Went Hensley began incorporating them into his services at his Church of God with Signs Following. Many others have followed in his footsteps. And many have been bitten such as John Wayne “Punkin” Brown and Jamie Coots, whose son Cody was also bitten while preaching but saved when friends defied the church dictates and got him medical treatment.

For the most part, medical treatment is not offered in the circumstances because it is felt that it’s up to the Lord whether the preacher survives or not. After all, it is religion and the Lord can save you then what’s the point? Not to mention, that many of these groups feel that sipping strychnine is also good for you and will prevent you from dying if you are bitten by a snake. Yeah, that makes good medical sense. Add another poison to the poison authority in your system.

I use much of this in my third Samantha Cody book, Original Sin. One of the bad guys in this story is a snake-handling preacher. During my research for this book, I stumbled across a wonderful book titled Salvation on Sand Mountain. Sand Mountain is maybe 30 or 40 miles from where I grew up so obviously the title intrigued me. Once I got the book and began reading it I discovered it was wonderfully written and then discovered that it was nominated for a National Book Award. It is written by Dennis Covington and is the story of Glenn Summerford, a snake-handling preacher who attempted to kill his wife with a snake.

From ORIGINAL SIN:

“I knew you’d come back to us,” John Scully said as Lucy and Sam walked into the church. He and Miriam were standing near the pulpit. 

“Back?” Lucy said. 

“Back to the church.”

“That implies I was ever here.”

“You were,” Miriam said. “From the moment you breathed your first breath.”

“You’re not making sense.”

Scully smiled. “You have always been a part of us. Martha and your parents saw to that.”

Lucy glanced toward Sam. “Am I missing something here?”

“Doesn’t make sense to me either,” Sam said.

“You were baptized into the church when you were only days old.”

“No offense, but I don’t remember that. And no one ever bothered to tell me.”

“But deep inside you know it’s true,” Scully said.

“I don’t think so.”

Felicia walked in, carrying a wooden box. She placed it on a table to Scully’s left. The unmistakable buzzing of snakes rose from the box. Scully raised the lid and casually removed a fat rattlesnake. Its buzzing now adopted an angry tone.

Lucy and Sam each took a step back. 

“I don’t think that’s a good idea,” Sam said.

“Don’t worry. I’m immune to the poison.”

“I’m more worried about me and Lucy,” Sam said.

“He’s been bitten a dozen times,” Miriam said. “His faith protects him.”

“That and a little strychnine,” Scully said.

“Strychnine?” Lucy asked. Her attention never drifted from the snake that now waved its head around as if looking for a suitable target. She felt perspiration gather along her back as her heart rate clicked up a notch. God, she hated snakes.

“A little sip neutralizes the poison,” Miriam said.

“I must have missed that day in med school,” Lucy said.

Miriam offered a maternal smile. “Can’t learn everything from man’s books. Only from the word of the Lord.”

The snake coiled around Scully’s arm, head raised. Lucy felt as if it was watching her. She took another half step back, Actually, she wanted to run out the door, but fought the impulse.

“Why snakes?” Sam asked. “What do they have to do with Jesus?”

Lucy knew Sam was playing cop now. Ty and Bump had told them about Scully’s insane beliefs. And Sam had told her that Gladys Johnston had said the same thing. Sam was merely asking questions she already knew the answer to. Seeing if Scully changed his story in any way. 

Now it was Scully’s turn to offer a paternal smile. It faded and his gaze seemed to glaze over. He spoke.

And he said unto them, Go ye into all the world, and preach the gospel to every creature.

He that believeth and is baptized shall be saved; but he that believeth not shall be damned.

And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;

They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.

So then after the Lord had spoken unto them, he was received up into heaven, and sat on the right hand of God.

And they went forth, and preached everywhere, the Lord working with them, and confirming the word with signs following. Amen.

The quote Sam had shown her. The one Scully had written on the back of a menu.

“Mark Sixteen,” Felicia said.

“I’m afraid I don’t understand,” Sam said. “This is the scripture that tells you to play with snakes?”

Scully gaze hardened. “It’s not play. But you wouldn’t understand.”
