Any writer, reader, and fan of mysteries, thrillers, suspense, and other books and television shows and film that involves crime scene investigation, will most likely have heard of Luminol, the chemical that causes chemiluminescence.

Chemiluminescence, the vivid bluish glow we’ve seen on countless crime shows, occurs when Luminol contacts an oxidizing agent such as the hemoglobin found in blood. Other agents can cause a similar reaction (copper, bleach, etc.), but it is blood that causes the most vivid glow. And it is this reaction that is of particular interest both real and fictional investigators.

Even bloody footprints reveal themselves when exposed to luminol.

Sirchie, the world leader in crime scene investigation technology and products, describes Luminol as:

“Luminol is a chemiluminescent substance that can be used as a presumptive test for the presence of blood. Making use of the peroxidaselike activity of the heme portion of hemoglobin, Luminol produces a bluish-white light that can be viewed in total darkness. Invisible blood stains react with the Luminol reagent by luminescing—darkness is essential. It can also be photographed or videotaped with the aid of the SIRCHIE® KRIMESITE™ IMAGER. A very useful test for searching large areas for blood especially if the area has been cleaned up. Sensitivity:1:100,000.”

Sirchie’s LUMINOL8 Contents:
2- LUMINOL 8B bottles of solution, 8 oz. each
2- LUMINOL 8A packets of dry chemicals, Net. Wt. 14.5 gms
2- Spray Head Attachment

Sirchie’s BLUESTAR Forensic Kit “affords the Crime Scene Investigator a complete tool to determine the presence or absence of blood. The extreme sensitivity of BLUESTAR allows the detection of bloodstains down to 1:10,000 dilutions, including minute traces that have been washed off, with or without detergent. And unlike other blood reagents, total darkness is not required. With practice, it’s unlikely to get confused between blood and false positives as the luminescence is different in color, intensity and duration. Subsequent DNA Typing and ABO Typing is possible because BLUESTAR does not alter the DNA in suspect blood stains.” ~ Sirchie

Luminol is a presumptive test, not a confirmatory test.

 

 

 

 

 

 

Luminol presents challenges, such as its potential to destroy DNA evidence when contacted, and its glow lasts for just mere seconds. Detectives must be quick with their photography skills!

Therefore, BGU Prof. Alina Karabchevsky, head of BGU’s Light-on-a-Chip Group, a member of the BGU Unit of Electro-Optical Engineering and the Ilse Katz Institute for Nanoscale Science and Technology, came up with a fantastic new idea … a device/chip that combines the use of luminol with gold or silver nanospheres.

Simply put, Dr. Karabchevsky invented a microfluidic chip that not only greatly increases the chemiluminescence intensity of luminol, but also extends its glow time. To sweeten the pot, the chip enables the detection of much smaller blood samples found at potential crime scenes.

“The method developed by BGU researchers will enable development of future detectors with improved sensitivity. We are currently looking for partners for further developing this promising patented invention,” said Netta Cohen, CEO, BGN Technologies.


What is a microfluidic chip?

Easy answer – a device (chip) that enables very small amount of liquid to be processed or visualized.

 

We all know how the story goes. A sly, blowhardish and extremely hungry wolf arrives at the front doors of the recently created homes of three very handy pigs, a trio of walking porkchops who’d built their individual abodes on prime pieces of suburban real estate.

The first pudgy, and not so construction-savvy pig fashioned his home from straw, and if you’ve watched HGTV lately you’ll recall that while inexpensive straw homes are susceptible to rot due to high moisture content, fire, and to the difficulty of obtaining homeowner insurance.

I imagine our first little porker thumbed his flat little nose at the rules, and safety, and bypassed the permitting process. I also believe he overlooked the possibility of wind damage and quickly learned of his error shortly after the wolf announced his presence on the front stoop.

“Little pig, little pig won’t you let me come in?” the mangy wolf cried out to pig number one.

“No, no, no, by the hair on my chinny, chin, chin,” said the worried hog.

Well, you know what happened next. The wolf, of course, huffed and puffed and in a matter of seconds enjoyed a tasty pulled pork appetizer.

The twisted and curly “tail” continues with the wolf’s forceful exhalations destroying pig number two’s stick-built home. As a result … pork roast for the entire Wolf family. And, as before, he’d gotten away without leaving a clue. Not even a paw print.

Then the murdering wolf, now deemed a serial killer by the local media, moved on to his next intended victim, the pig who lived in the brick rancher at the corner of Garlic and Rosemary Avenues.

Exasperated police almost captured the wolf thanks to a 911 call from the couple next door, Porky and Petunia, who’d seen the sneaky canine approaching pig number three’s doorstep. But, as bad luck would have it, the wolf escaped on foot, well, on four feet, actually.

The wolf was careless, though, during his third attempt at pig-killing. He’d forgotten it was the time of year when his species sheds their winter coats. Yep, you guessed it. Cops collected a few discarded hairs and subsequently rushed them to the lab where scientists immediately began testing them using an astonishing new process. They ‘d know the identity of the killer very soon. But this is fiction …

The Real Meat of the Story

Okay, the tale above is a bit stupid, I know. But I wrote it as a prelude to the true subject matter of the day—identifying a criminal suspect using his or her shed hairs found at a crime scene.

It’s fairly common knowledge that scientists and other lab experts, as well as law enforcement investigators and writers, are already familiar with the use of human hair from the head as a source used to identify people through DNA testing, etc. Suppose, though, that any hair from any part of the body could be used to identify the person who shed it, not just hairs from the head. To have this capability would be HUGE in the real world of crime-solving.

Sure, writers make up stuff like this all the time to help tie up loose ends in their books. After all, Jack Reacher, Bosch, DD Warren, and Tami Hoag’s Detectives Fourcade and Broussard, well, they’re unstoppable because their creators make it so. But actual cops must use actual evidence and actual crime-fighting tools and equipment to locate killers, such as the extensive catalog of items developed and manufactured by Sirchie.

But here in the world of genuine cops and murderers, the use of wishful thinking and fictional methods and procedures is not an option that’s available to local, state, and federal law enforcement.

However, thanks to a group of researchers, fiction is now a reality.

Yes, a groundbreaking technique of human identification using hairs from ANY part of the body is now possible. It’s the result of a yearlong study by researchers from Lawrence Livermore National Laboratory’s Forensic Science Center and Michigan State University.

The process interprets hair protein chemistry and how it effects protein marker identification.

Chemist Fanny Chu, a graduate student and researcher at MSU, along with other researchers involved in the Lawrence Livermore/Michigan State University study, took the hair testing process a step further by studying and comparing arm and pubic hair with head hair. The result—the hairs fundamentally presented the same data as head hair.

Additionally, the protein content of the hairs indicate whether a single hair is from a person’s head, arm, or pubic area, etc.

The team also learned that the protein content of pubic hair is appreciably greater than head and arm hair.

A single one-inch strand of hair has a unique pattern, much like DNA or fingerprints, that distinguish a person from among a population of 10 million people.

Fun Fact: Human hair proteins are chemically more stout than nuclear DNA. In fact, scientists have detected protein markers in human hair that’s more than 250 years old.

MurderCon

Police officers put themselves in harm’s way, repeatedly, over the entire length of their careers. It’s the nature of the job. A typical day can include serving and protecting the public, dealing with civil unrest, and even having to face man-made and natural disasters. Most police officers prefer to live in a city that minimizes their personal risk of injury in the line of duty, that pays a good wage, and where the typical officer’s workload is reasonable.

Analysts at Safety.com have studied nearly 300 cities and regions across the nation to find the top 20 cities for police officers in 2019.


Key Takeaways

The coast of the United States accounts for less than 10 percent of the country’s land mass, yet it is home to nearly 40 percent of the population, some 55.8 million people. [28] With a few exceptions, coastal or near-coastal regions offer police the best career opportunities. For those not interested in living near the coast, three regions offer favorable alternatives …

Please do hurry to reserve your place at this exciting one-of-a-kind opportunity for writers, readers, and fans. It’s never been done before and most likely will not occur again.

This is your chance to attend the actual hands-on classes taught to some of the best homicide investigators in the world, with all sessions taught by renowned instructors and experts.

This is not a citizens academy nor is it a collection the typically run-of-the-mill classes offered at so many writer events. In fact, even the Writers’ Police Academy, the premier law enforcement training event for writers, has not presented this extremely high level of intense and detailed instruction. Yes, MurderCon is that good.

This is as close as it gets to investigating an actual murder

This year we’ve gone over the top by carefully and painstakingly designing and offering a never-before-available opportunity for writers, readers, and fans. It’s the ultimate homicide investigation training event.

To sweeten the pot, immensely, we’ve arranged to host this event at the very source of much of the equipment, tools, and techniques utilized by homicide detectives …

SIRCHIE

You all know the importance of setting in your books, right?

For example, when your protagonists use Supergluing tactics to develop latent prints …

MurderCon attendees will work and train in the very setting where the fuming chambers were developed, brought to life, and then manufactured. Fingerprinting powders and brushes? Designed and made there too. Fingerprinting powders of all types, and there are many. Check. DNA testing? Check. Alternate light sources and RUVIS technology? Check. Evidence collection tools and kits and methods. Check. Buried body investigations. Check. Bloodstain patterns? Check, and some of the best investigators in the business teach those classes at the remote Sirchie compound just outside of Raleigh, N.C.

This seemingly endless list of top investigation education goes on and on and on. And you, non-law enforcement outsiders, have the rarest of rare opportunities to train there, at Sirchie, the global leader in crime scene investigation and forensic science solutions.

Imagine your senses being activated in ways they’ve not been in the past. That’s what’s going to happen at MurderCon, you know.

After MurderCon you’ll have the added knowledge of the very real odors associated with buried body and arson scenes.

Your eyes, ears, fingers and hands and noses and emotions will finally be able to join in with the writing of your next murder scene, because you’ll have had first-hand experience instead of relying on something you’ve read or heard someone say.

What you can expect upon graduating from MurderCon

A Fantastic Value!!!!

Browse Sirchie’s training schedule and you’ll see many of the sensational classes offered at MurderCon. Then peek at the cost of those sessions and you’ll quickly discover what a fantastic value it is to attend MurderCon.

MurderCon registration—the low fee of just $425—covers all classes, lunches, transportation to and from Sirchie, and more. Sirchie’s fee to attend, for example, just two classes—Clandestine Grave Search and Recovery and Arson Investigation for Law Enforcement—is just under $800. That’s the cost to attend only two of their outstanding classes (an extremely low fee for law enforcement, by the way).

MurderCon attendees have the opportunity to attend FIFTEEN different classes for nearly the same price as it would be to attend two at Sirchie.

What. A. Huge. Deal. For. YOU!

MurderCon Registration

During the first two days of Evidence Collection Training, we used a number of chemicals, fingerprint powders, and brushes, and employed several different fingerprint lifting techniques on a variety of tricky surfaces. We discussed the benefits of both cheap and costly Alternate Light Sources.

Our notebooks were filling up and theories of the perfect crime were flying around the class. We kept quizzing Robert Skiff, our instructor, about ways to ‘get away with the murder of the decade.’ But, as we learned, there is no perfect crime. That pesky trace evidence will always be waiting at every scene for the investigator to discover it, photograph it, tag it, bag it, and transport it without losing the integrity of the sample.

It was time to visit the plant – see how the powders, brushes, and other crime scene paraphernalia were made.

Sirchie manufactures most of its products in-house. The specialized vehicles for SWAT, bomb rescue, arson investigation, and surveillance work, etc., are built in New Jersey, but the smaller products are produced right in North Carolina.

Security was carefully controlled throughout our tour. Most of our group writes crime fiction, so we are always looking for a way our fictional criminals can break in (or out of) a wild assortment of locations. As we walked through the stacks and aisles of products, we commented to each other on the smooth organization and many checks Sirchie had in place. Cameras everywhere. Limited access to the assembly floor. Labyrinths a person could easily get turned around in. If we got separated from the group while taking an extra photo or two, we were found and escorted back by an always friendly employee.

Of course, we couldn’t turn into rogue students anyway. Our fingerprints littered the classroom and they knew where we lived.

Security plays a part in the assembly model as well. Each product they create is put together from start to finish by hand. There are no assembly lines because of trade secrets and a dedication to preserving product integrity. Personnel are carefully screened before being hired and qualification for employment includes graduate degrees. No criminal history whatsoever is allowed. Every employee comes through the Evidence Collection Training Class so that they understand what Sirchie does as a whole.

https://www.leelofland.com/wp-content/uploads/2012/07/ToolandDieMachinesN3248.jpg

Templates for the various products are created in-house. The operators of these machines are highly trained experts. Quality control is paramount, so training is constant.

https://www.leelofland.com/wp-content/uploads/2012/07/PrintedSuppliesIMG_0313.jpg

All the printing is done in-house. The printing area was stacked with cases of items being packaged for shipment. We saw ink strips large enough to process tire treads.

https://www.leelofland.com/wp-content/uploads/2012/07/FieldKit_0196.jpg

Field Kits are created for general use by investigators, but can be specifically designed for a special need. The small vials contain enough chemicals to test unknown stains and substances at the scene. Note the dense foam holding the vials and bottles firmly in place. The kits are usually kept in the trunk and probably get tossed around quite a bit. The foam insures against breakage during car chases and while bumping across uneven road surfaces.

https://www.leelofland.com/wp-content/uploads/2012/07/FingerprintBrushesIMG_0090.jpg

There are fiberglass brushes, feather dusters for the very light powder, regular stiffer brushes, and magnetic powder brush applicators.

https://www.leelofland.com/wp-content/uploads/2012/07/GunBoxIMG_0205.jpg

If a handgun is seized for evidence, there needs to be a simple, yet effective way to track chain of possession.

*Bag the gun to preserve the fingerprints and

*drop the gun in the box.

*Then fill in the blanks on the box.

*Easy to stack and store until needed.

Think of all the cases that may be ongoing in a large jurisdiction – the evidence is not sitting at the police station. It’s in a warehouse someplace, and needs to be easily identified when required for court. In addition to several sized boxes for guns and knives, etc. Sirchie also provides an incredible assortment of resealable plastic bags for preserving evidence like clothing, unidentified fibers, etc.

https://www.leelofland.com/wp-content/uploads/2012/07/WendyMagneticPowderIMG_0200.jpg

Magnetic powder was being processed that day and then put into rows and rows of jars and jugs. Before it is sent out to the customers, each lot is tested for moisture content, appropriate ratio of ingredients and other trade secret tests. We joked about taking some back to class for the next round of fingerprint study and were surprised by how heavy the jugs were.

https://www.leelofland.com/wp-content/uploads/2012/07/CyanowandCartridges4GlueGunsIMG_0227.jpg

No, she’s not making bullets. She is assembling the cyanowand cartridges used for fuming with superglue.

Sirchie makes riot gear.

This is not a photo of something from a SyFy movie. At the center of the shot is a helmet template. The drills encircling the template are aimed at spots where holes are needed for each helmet, depending on the type of helmet in production. All the holes are drilled at the same time.

The Optical Comparator, as well as the other machines, are built to order by hand.

While in the warehouse, we learned that if a product is discontinued, it is still supported by Sirchie. That means that if a law enforcement officer calls up with a problem a few years after purchasing a machine, he can still get help. Reassuring for jurisdictions with a tight budget that can’t afford to replace expensive equipment every year or two.

Sirchie sends supplies to TV shows, so next time you’re watching a fave detective or examiner lift prints with a hinge lifter, it may have come from Sirchie.

Great tour, great people who work so hard to keep the law enforcement community supplied with the gear needed to catch the bad guys.
