Have you ever been bitten by an insect? How about a snake? Or a frog? Or a snail? I’ll take a fire ant bite over the bites of some of the animals in this article any day.

I would bet that most of you have endured the after effects of a mosquito bite – the itchiness, the redness, the swelling, but rarely does anyone die from it. There are nasty diseases that a mosquito can carry – i.e., Malaria and the Zika virus – but the everyday, backyard variety generally just delivers an annoying couple of days of discomfort. We can’t tell the difference by just looking at them as they dive at us, so we use insect repellent to ward them off. There are couple of great products that golfers use to keep pesky gnats, horse flies, and skeeters away, but, there is no magic spray that works to chase away the deadliest animals that co-exist with us on the planet. We have to rely on treatment after the fact, or the best idea of all: avoidance.

Here are ten of the worst:

Some animals have developed neurotoxins to dispatch their victims. The worst spider in the world is found in Australia – just in Sydney, to be exact. The Sydney Funnel Web Spider can kill a human or a monkey within 15 minutes. Apparently, no other animal is susceptible to the poison. There is an anti-venom, but you’d have to be really close to the hospital to get treated in time.

The South African Spitting Scorpion uses three neurotoxins to protect itself – one to stun, one to paralyze and one to kill. It spits the lightest dose when chasing the victim away, but it only needs a billionth of a gram of the deadly dose to kill a small animal. Death is not pleasant, with tremors and convulsions that go on even after death.

The Lonomia Caterpillar is responsible for over 500 deaths in the past twenty years and kills by causing hemorrhaging near the site of the bite. The victim’s blood no longer clots and this condition spreads as the body tries to cope. Scientists don’t yet know the composition of all the toxins involved.

Unlike other poisonous animals, the Poison Dart Frog creates its toxin from its diet. Scientists have discovered that in captivity, the frog is rendered harmless by changing its diet. That means that even if the frogs in my photo above had escaped, they would have hopped around, doing no damage to me at all if they had touched me. Good thing, because one little wild frog from Central or South America has enough toxin to kill about ten fully adult humans. Hop, hop, hopping about, enticing us to touch its pretty skin, doing its worst by causing heart attacks.

The famed Puffer Fish carries a neurotoxin that is 100 times deadlier than potassium cyanide. What may not as widely known is that same toxin can zap you if you touch certain varieties of sea snails as well as the blue ringed octopus, a small but nasty bit of sea life. Contact with one of these unfriendly sorts can cause blindness, paralysis, and/or death. And while the Marbled Cone Snail may be gorgeous to look at, there is no known antidote for a strong enough dose of its venom. I’ve never been a strong ocean swimmer, but when I stick my toe in a wave at the shore, I expect to be alive afterward, pretty sea snails or not. Maybe I’ll forgo the next snorkeling trip.  😉

The Inland Taipan is among the deadliest snakes on Earth. Anybody that gets bitten by one of these can die within 45 minutes. It’s an Australian snake and there is anti-venom for the bite, but I wouldn’t want to count on getting back to civilization in time to get the treatment. If I was a snake handler Down Under or if I lived in the Outback, I’d think seriously about keeping a vial of the remedy on hand.

The King Cobra can strike fear into the heart of anyone that gets within spitting distance. Just a 1/4 ounce of its venom (about 7 ml) can kill a full grown elephant within minutes. To put that into perspective – about twenty grown men could die from that same 1/4 ounce dose. The good news is that unless you’re traveling to India or China, or the local zoo lets one escape, you’re safe.

Several varieties of Jellyfish can deliver stings that cause a great deal of pain and sometimes death. They are physically brainless, but their make-up is all about survival. Tentacles can be anywhere from less than an inch (the translucent Irukandji) up to ten feet long (the Portuguese Man O War). They are found in oceans all over the world, can be almost invisible or quite colorful (the Sea Nettle found near the Chesapeake Bay in the USA). My advice? If you see one, swim away as fast as you can.

If you’re using the information in a book you’re writing, choose your poison source carefully. Somebody has to gather that poison before it can be injected or mixed with food. Will it be the villain or someone she/he hires?  There are medical uses for some of the neurotoxins – those can be purchased legally with the proper credentials. On the other hand, snake venom is not easy to collect, and somebody might actually have to catch the snake first.  Snake bags anyone?

Do you have a favorite villain in literature that has used a rare animal-based poison to do his/her evil work? Please share in the comments below.  🙂

KN, p. 82 “Is that your footprint?”

If there are no paragraph separations in this article, please double-click on the title to create a more readable version.

 

It’s been raining off and on for days. It rained last week during a party, and people were tracking water and a little mud from the driveway runoff onto the porch all afternoon. We had so many different kinds of footprints that it would have made for a great crime scene demonstration.

Because, one of the most overlooked pieces of evidence at a crime scene is created by footwear.

 

Imagine: If a window breaks as a thief enters the premises during the commission of a burglary, the glass will fall into the house, and onto the floor or rug below the window. When the thief steps through the window, unless the thief has wings, he/she will probably plant a foot right in the middle of the glass. And walk through the house, most likely tracking minute pieces of that glass. That glass may also become embedded in the grooves of the sole of the shoe, creating a distinctive footprint.

 

If the investigating officer can place a suspect at the scene with the footprint, then there is probable cause to fingerprint that suspect and hopefully establish a link to the crime.

 

A new method of eliminating suspects right at the scene involves stepping into a tray that contains a pad soaked with harmless clear ink that doesn’t stain, then stepping onto a chemically treated impression card. No messy cleanup, immediate results, and it can even show details of wear and tear on the shoe. This can be a way to establish a known standard (we know where this impression came from) to compare with multiple tread prints at the scene.

Footwear Clear Ink Impression

Another tool for creating a known standard is the foam impression system. It takes a bit longer, (24 hours) but clear, crisp impressions can be made, including of the pebbles and bits stuck deep into the grooves and the writing on the arch. Very helpful when trying to place suspects at the scene. A rock stuck in the sole is a random characteristic that can’t be duplicated, so becomes another point of identification.

This is how it works: Somebody steps into a box of stiff-ish foam – a bit like stepping into wet sand.

 

An impression is made instantaneously. The detail is great – down to the wear on the heel.

Pre-mixed dental stone (made with distilled water and the powder) is used to fill the impression.

It takes 24 hours for the cast to become firm enough to pop out of the foam. We now have a permanent record of the footwear tread, which could be used for comparison to other prints found at the scene.

Footwear Casts

Occasionally footprints are found on the ground outside a window or in the gardens surrounding a house after a burglary or homicide. Ever see a crime show on TV where the fictional investigator makes a snap judgment about the height and weight of the owner of the footprint because of the depth of the impression? That’s merely a plot device and is not scientific evidence in real life. A crime scene photographer or investigator can photograph the footprint (next to a measurement scale), make a take away cast, and then compare the impression with those of the suspects or other bystanders at the scene. Beware: making a cast of the print destroys the print, so a photograph must be taken before pouring that first drop of dental stone.

Footprints can be found at bloody crime scenes as well. The suspect walks through the blood, tracks it through the house, cleans it up, but the prints are still there, even though not obvious to the naked eye. Blood just doesn’t go away, no matter how hard you try to get rid of it. It seeps into the cracks and crevices of a floor and even behind baseboards.

 

A savvy investigator will collect sections of carpet (or flooring) taken from where the suspect might have walked during the commission of the crime, then conduct a presumptive test for blood (LCV – Aqueous Leuco Crystal Violet), find a usable footprint, compare it to a known standard, and then be able to place the suspect at the scene.

 

 

Be careful where you walk. That footprint can be used as evidence.

KN, p. 218 “What Does the Federal Bureau of Investigation Do?”

If there are no paragraph separations in this article, please double-click on the title to create a more readable version.

“The Federal Bureau of Investigation (FBI) is an intelligence-driven and threat-focused national security organization with both intelligence and law enforcement responsibilities.”*  It is the chief fact-finding branch of the Department of Justice and helps other agencies by sharing that information and providing training.

Its mission is:

“To protect the American people and uphold the Constitution of the United States.”*

In 1908, the United States had about 100 cities with 50,000 people. The rest of the population (about 83 million) was spread throughout the rural areas of the country. Law enforcement personnel at the local level were often poorly paid (and were sometimes volunteer) members of the community. Murders were handled by local investigators and still are to this day. For the majority of the cases, murder is not a federal crime, unless carried out across State lines.

Prosecution of border security issues or organized crime was limited in 1908 since there was no adequate way to enforce the law at a national level. In fact, few criminal laws even existed at a federal level. For the most part, individual States and local jurisdictions handled their own criminal investigations, and sometimes that led to political corruption, corporate criminal behavior, and even slave labor in factories. Federal agencies were stretched thin or were nonexistent in some parts of the country.

President Teddy Roosevelt supported the idea of modernizing law enforcement, so when his Attorney General hired 34 of his own investigators (including nine seasoned Secret Service agents) to assist the Department of Justice, Roosevelt wholeheartedly endorsed the action. A few months later, the Bureau of Investigation was officially created. Hardly a large force, but it was a start.

At the beginning, incidents involving car theft across State lines, civil rights, and various kinds of fraud were the typical cases. The FBI also took on treason and domestic terrorism, and Congress (previously reluctant to loosen the purse strings) began to see the value of a national law enforcement agency.

It’s interesting to note that the Mann Act or “White Slave Traffic Act,” was passed in 1910 to help stop interstate prostitution and human trafficking, and the FBI had a role in the early investigations. One hundred years later, it has become an international problem and requires cooperation from many different agencies to obtain successful prosecutions.

World War 1 brought us the problems of sabotage by foreign agents against our military ships and munitions plants, as well as international smuggling. The FBI had entered the so-called spy business and worked hard to eliminate those threats.

 

In 1924, it was recognized that fingerprinting was a reliable way of connecting (or eliminating) individuals to a particular scene, and to collect that information in a central location would be helpful to other law enforcement agencies in the United States. Now, the FBI gathers and classifies fingerprints from convicted felons and other criminals, military personnel, federal applicants and employees, and shares that information with appropriate agencies. Additionally, fingerprints of military detainees and other persons of national security interest are being collected for national security purposes.

Formerly called Automated Fingerprint Identification System (AFIS), the program processes over 63,000 prints a day, is now integrated with other forms of identification and called IAFIS, and can deliver digital information in as little as two hours. It is used in connection with biometric databases (facial and voice recognition) for more accurate identifications. Next Generation Identification (NGI) combines biometrics, fingerprints, and palm prints to expand identification possibilities.

One of the programs developed by the FBI is the ‘Ten Most Wanted’ list. It began in 1950 as a way to call attention to fugitives who might otherwise remain at large. Each new list is posted in United States Post Offices and on the FBI website.

Since 1950, 518 fugitives have been on the list, and 484 have been apprehended or located. The stats below are from the FBI site:

    • 162 fugitives have been captured/located as a result of citizen cooperation.
    • Two fugitives were apprehended because of visitors on an FBI tour.
    • The shortest amount of time on the list was two hours, by Billy Austin Bryant.
    • The longest amount of time on the list was over 32 years by Victor Manuel Gerena.

With the advent of increased world-wide terrorism, the computer and cyber-security age, more complex corporate crimes, and a global awareness of human trafficking, the focus of the FBI has shifted.

At the end of 2017, there were over 35,000 employees, made up of intelligence analysts, field agents, language specialists, scientists, and information technology specialists. They are tasked with investigating:

  • Terrorism
  • Counterintelligence
  • Cyber Crime
  • Public Corruption
  • Civil Rights
  • Organized Crime
  • White-Collar Crime
  • Violent Crime
  • WMD (Weapons of Mass Destruction)

Stay tuned for posts about Quantico and training for the FBI, and interviews with former FBI agents.

1969 Latent Print Match
A latent print removed from a 1969 murder victim’s car was later determined to be a match to the suspect’s fingerprint (inset) contained in the FBI’s Integrated Automated Fingerprint Identification System (IAFIS). The Houston police detective and Texas Department of Public Safety latent print technician instrumental in solving the cold case were honored by the FBI with the 2011 “Latent Hit of the Year” Award.
