TV makes the job of a CSI tech look like a lot of fun.

It looks like an easy job, too. Get a call from dispatch, arrive at a crime scene, pop on the gloves, shine a flashlight around, take a few photos, collect the evidence along with your team of 4-5 colleagues and go back to the lab an hour or so later, ready to process all of it.

Have the real CSI techs and law enforcement professionals stopped laughing yet?  😉

Here’s the reality:

Most small towns (under 50,000 people) have no CSI lab. None. The local police in smaller towns are able to collect fingerprints, but most have to send them off to a State Lab to be processed.

Many towns, even with a population of 100,000 people, don’t have a ballistics lab to check the caliber of any bullets/casings left behind at the scene or found in the victim’s body.

North Carolina (as of 2022) had a population of 10.7 million, and has three State crime labs – one full service and two regional labs.

New York State (as of 2022) had a population of 19.68 million, and has four State crime labs – one full service and three specializing in varied areas.

New Jersey (as of 2022) had a population of 9.26 million.  It has seven  State labs.

Texas (as of 2022) had a population of 30.03 million, with a full service forensic lab in Austin and 14 regional labs, some conducting only drug testing, and others close to full service.

And all of those crime labs are processing evidence from all kinds of crimes (burglary, robbery, rape, arson, cold case, assault, etc.) not just murders. It take a few hours to get the prints, preserve the evidence, bag and tag it for transport, but it takes months to get it processed, because there is a long line of cases ahead of yours. In some States, the wait is as long as 18 months. That is not a typo, folks. Eighteen months to wait until the evidence can be processed. Even if the case is a high profile one, moving to the head of the line might only shorten the wait to 2-3 months, because there are other high profile cases in line as well or cases that are already in court, waiting for clarification of the evidence.

 

There is no such thing as instantaneous fingerprint matches. See the article about fingerprint analysis here. There are now handheld machines that scan a viable fingerprint at the scene, but that only speeds up the collection process, not the identification of the fingerprint. (I was recently told that a new fingerprint reader can return an answer in 45 seconds, but some fingerprint experts are reserving judgment as to the accuracy of the matches.)

Get the picture? The State Bureaus of Investigation are short-staffed and the cases more numerous, as attorneys seek to prove or disprove beyond the shadow of a doubt that the evidence gathered at the scene linked their clients to the crime.

In general, the analysts examine all types of evidence related to criminal investigations and assist the criminal justice system. They can provide:

  • Consultation on the value, use, collection, and preservation of evidence,
  • Analysis and comparison of evidence from crime scenes and/or people,
  • Expert testimony in court proceedings, and
  • Assistance for collecting evidence and processing crime scenes,
  • Forensic science information to law enforcement agencies and district attorneys.

ALL of that evidence must be collected in a thorough and efficient manner by the Crime Scene Technician or Crime Scene Investigator. Cases are won and lost on how the evidence is handled – both the chain of custody and the collecting of the correct evidence can be factors in how a suspect is perceived.

I had a chance to chat with a CSI who has been in the field for about 10 years. She generously shared information about her day – soooo different from the image of the CSI jobs projected on TV.

She enters a crime scene after a Patrol Officer has cleared the house (made sure that no unauthorized person is in it). A Deputy might walk her through the house, and depending on the crime, the owner of the house then walks her through, pointing out items that might have been disturbed or areas where items are missing. She takes notes during the tours so that she can come up with a Plan of Action – how to process the scene.

In general, she will take photos first, and then collect the evidence. If a homicide is suspected, she might take video as well as still photographs.

She might see patterns of wreckage, or concentration of destruction, or even similarities with other cases, but it is not her job to focus on the M.O. (modus operandi) or narrow her collection efforts based on a hunch. She is there to collect all the evidence.

She might be looking for:

  • Fingerprints
  • Blood spatters
  • Fibers
  • Footwear impressions
  • Tire impressions
  • Tool impressions
  • DNA samples (hair, nails, blood, saliva, etc)
  • Murder weapon
  • Point of entry
  • Kinds of items taken

What a CSI leaves at the scene is sometimes as important as what he/she collects, so it is vital to be thorough. The detectives and attorneys decide what is significant to the case.

The trunk of a CSIs car is filled with the tools of the trade. They have kits for each type of evidence collection and if they know in general what the scene will call for, they may grab an additional kit from headquarters. They might even carry a tarp to cover the ground (creating a collection place for the evidence) if the scene is outdoors – such as a train wreck.

The CSI I interviewed works in Major Crimes for the Sheriff’s Department, and when she is called to a scene, she works 12-hour shifts, by herself. In most cases, she collects all the evidence, bags and tags it appropriately, and hands it all to the detective in charge. She works 14 days a month, equally divided between the day shift and the night shift.  On occasion, a 12-hour shift is not long enough to collect everything at a particular crime scene, so she stays a bit longer to finish. If it looks as if she has to work for another shift, a Patrol Officer will guard the scene until she returns to finish collection on her next shift. If the case merits 24-hour collection (because of weather or the condition of the scene/body) the CSI on the next shift will continue the collection, with any evidence collected up to that point handed over to the new person.

Clear chain of possession of the evidence dictates that in a case where collection goes on for more than one shift, limited people will have keys to the building. There are evidence cards showing who collected it, and anyone entering or leaving the scene will have to sign in and out with the Patrol Officer on duty.

KN, p. 258 “Foxglove: Pretty, Medicinal, and Deadly”

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

In general, an investigation into a suspicious death must show that the suspect had motive, means, and opportunity in order for a D.A. to pursue and prosecute a case.

A traditional mystery (not much blood and gore, with an emphasis on the howdunit, whodunit, and why) might focus on the little old lady who seems that she would never harm a soul. In fact, she may be the dastardly evildoer in a cleverly plotted story.

A detective must discover why the victim needed killing – the motive. Was the crime committed to cover up another crime? Was the mild-mannered little old lady, barely making ends meet through a glitch in her pension system, cashing social security checks that belonged to a long dead spouse now buried in the garden? Did the victim uncover the truth and need to be silenced before spilling the beans? Readers and jury members alike might relate to her desperate plight as a motive that pushes people over the edge.   

The detective must show that the suspect had the means to pull it off.

What would a little old lady do? The victim had no outward signs of blunt force trauma from being struck by a baseball bat or golf club. The answer lies in the multi-colored display of foxglove, readily available in our senior citizen’s garden. Every part of the foxglove plant can cause allergic reactions and a few fresh leaves are enough to kill a person. Collecting the foliage can irritate the skin and eyes, so wearing gardening gloves, eyeglasses, and a mask (commonly worn in pollen season) would have protected her when working with her weapon of death.

A detective must figure out if the suspect had an opportunity to deliver the poison to the victim. The foxglove leaves look very much like large baby romaine, if a bit fuzzier. But lathered in salad dressing at a neighborly gathering, nobody would be able to tell the difference.

Or, the senior citizen could bake up a special plate of brownies and share them.

From J.K. Rowling’s Harry Potter to Agatha Christie, foxglove has been a popular way to ‘off’ annoying people in fiction. Snape uses foxglove to make a potion in Potions 101 and Christie mixed it with other, edible greens in the garden in “The Herb of Death.”

My wife, Sheila, picked up six plants in three different colors at the garden center. I warned her about washing her gloves after handling the plants. All protocols were followed and no brownies have been made recently at our house.

 

So, why do we allow foxglove to be grown if it can be deadly?

The botanical name for foxglove is Digitalis purpurea. “Digitalis” is heart medicine made from foxglove. With a controlled dosage, digitalis is valuable in treating heart failure, but the wrong amount of foxglove can cause irregular heart function and death. Long-term use of foxglove can lead to symptoms of toxicity, including visual halos, yellow-green vision, and stomach upset.

The good news is that measuring digoxin (a form of digitalis) concentrations in the blood can help detect foxglove poisoning. If the detective and the other investigators are savvy about plants and gardens and the neighborhood dynamic, asking the right questions will uncover the reason and method of the deed. Case closed.

KN, p. 235 “Crimes Against the Earth”

Earth Day is observed in the third week of April every year.

Remember the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) commonly known as the Superfund Act of 1980? It was passed after several disasters in the 1970s involving waste storage facilities – complete with explosions, deaths, and toxic air pollution. The Superfund was designed to supply funds to clean up hazardous waste sites identified by the Environmental Protection Agency as problematic to human health. Money for the $1.6 billion fund was raised by taxing chemical and petroleum products.

 

Six years later, after a lot of delays and out right scoffing by companies at the law, a newer, tougher version was passed. It contained more enforcement authority, a wider ability to work with State agencies and other interested parties, and was funded with $8.5 billion.

I lived in a town that contained a dump site situated across the street from a well-known manufacturing plant that made auto parts. After years of struggling financially, finally going out of business and sitting empty, the plant was officially closed and emptied of its machinery in 1989. To local residents, it seemed to take many years to recognize that there was a ground pollution problem at the empty plant, and then for someone to remove the leaching barrels from the property across the street. The dirt left behind was dug up, removed and then new dirt brought in. Then carrots were planted in the field to draw out the remaining toxic elements.

 

12 years later, a golf course was built in that spot, the only business that will ever be allowed to be there. It was determined that the ground and perhaps the water as well, are too toxic for homes ever to be built on the site. Contamination resulted from past manufacturing operations, including leaks from above ground and underground chemical storage tanks. The toxicity reaches into the bedrock below the ground.

 

This is one small site, less than 20 acres in size, and it took years to handle the issues involved. It cost upwards of $200 million to get it to the point where a golf course could be built there. People can be there for recreation, but can’t ever live there.

 

That scenario is duplicated all over the world in towns that have manufacturing plants. Chemical spills and pollutants have made the drinking water undrinkable in a town in Michigan, causing illness, ruining property values, creating a nightmare for the residents. The Love Canal (near Niagara Falls) was a major chemical waste site and was the source of many serious illnesses. It was also a major impetus for the 1980 Superfund Act to be passed.

 

We can chalk up a lot of the questionable handling of chemical waste to ignorance when problems first occurred decades ago. Now? Not so much. There are oversite agencies, regulations to be followed, guidelines in place. The level of enforcement varies from State to State and from one community to the next. And, yet we still have spills, still have companies making poor judgments about safe construction techniques. The Deep Water Horizon accident happened twelve years ago this month, cost BP $65 billion in overall cleanup expenses and fees, and its impact is still being felt in the Gulf area.

The issues are complex. We need clothes, cars, furniture, fuel to run all of the pieces/parts of a modern society. We have limited resources on the planet. We have a growing population. Many towns around the USA recycle ‘gray’ water into public water systems (my present town included) because there is not sufficient fresh water to support a not densely populated county.

How do we balance our need for even the basic staples with our need to protect the planet from more harm, and ensure that generations to follow will have a healthy place to live?
