The Future Of Forensics

Have you ever wondered how forensics will advance in the future? If you're a crime writer or reader I bet you have.  

Well, wonder no more. Today, I brought along a friend of mine to predict the future of forensics. Garry Rodgers spent 20 years as a Royal Canadian Mounted Police homicide detective, followed by a second career as a forensics coroner. He also served as a sniper on British SAS-trained Emergency Response Teams and is a recognized expert in firearms. 

Garry's book, No Witnesses To Nothing, hit #5 on Amazon's Best-Sellers' list and is based on a true story-- a very unusual story where the paranormal played a role.

As a crime writer it's important that I get my facts right, so Garry is my go-to guy for all homicide related questions. His generosity overwhelms me. I'd like to take this opportunity to thank him once again for all of his help. Thank you, Garry! 

Without further ado, the future of forensics...


tech1Technology has made huge breakthroughs over the past thirty-five years that I’ve been around criminal and forensic investigation (CSI). Without question, the next thirty-five are going to bring mind-blowing advances. I’ve looked into my forensic crystal ball to come up with five things I think will be real by 2050.

But first... let's look at the top five since 1980.

1. Computers

When I started policing, the PC was unheard of.

tech2The only computing system we had was a mammoth of a beast that filled-up many rooms at headquarters. CPIC-- Canadian Police Information System-- was in its infancy as was its American counterpart, NCIC-- National Criminal Intelligence Center. Both systems are still around but, instead of having to phone to book appointments to use the system, the information now comes straight to the patrol cars or to a detective's smart device.

Computers have affected every facet of forensic investigation.

Despite complex computerized analysis being fast and accurate, the routine is much easier. Report writing is far simpler-- no more carbon paper to make multiple copies, no more white-out, and thank God for spell-check.

Communications are instant with internet email and gone are the days of waiting for a report to show up in snail mail. Training is done through computerized simulation, sketching is replaced by computer-aided drawing, and administration is now done by the keyboard. Computers are what allowed the next four advances to occur.

2. AFIS -- Automated Fingerprint Identification System

tech3The science of fingerprinting has been around nearly one hundred and fifty years, but the mechanism of storage and matching prints was cumbersome. Known prints from criminals used to be rolled in ink and stored on paper and the latent prints from crime scenes were lifted in powder and stored in plastic sheets. There was no effective system to easily match the two. Today, suspect prints are digitally scanned and stored in data bases. Latent prints are still lifted in conventional manners, but they're then scanned and put into a search engine where they can be matched right from the crime scene.

3. Photography

tech4Today's digital photography is a tremendous time-saver compared to the days of negative and image development. It's instantaneous to share over the internet, even allowing an investigator to snap a digital photo in the field and email it to the other side of the world. Another facet of crime fighting is the incredible amount of mobile and stationary cameras that are out and about in society which capture movements of criminals before, during, and after events. Many crooks have gone down because they failed to realize they were on camera.

4. Education

tech5Today's forensic investigators are far better educated than in the 1980's. Much of that is due to the ease of which information can be shared. Where it used to take great blocks of time and huge resources to assemble courses and conferences, many agencies now use webinars and on-line presence to create 'virtual' classrooms. Education and sharing information are the jewels in crime fighting.

5. DNA

tech13Deoxyribonucleic acid or genetic fingerprinting is probably the best crime-fighting tool ever developed. Today, thanks to the computer, the sophistication and expediency of DNA testing has led to it being commonly-- and accurately-- used in the majority of serious crime investigations. Many convictions have been secured on DNA evidence alone. Conversely, many innocent people have been cleared of suspicion due to elimination of DNA typing.

So that's what happened over the past third century. Ever wonder what's going to happen over the next third?

Well, I'm gazing into the crystal ball and predict five things.

1. Holograms

tech73-D technology is commonplace in movies and on TV. Many criminal prosecutions are already presented through computer-aided reconstruction to lay out the scene, bullet paths, vehicle motions, and blood-spatter patterns.

I see a day when virtual-reality holograms are imaged in the middle of the courtroom so the jurors can watch a total recreation of how the crime went down.

2. Brain-Scan Polygraphs

Conventional polygraphs have only slightly evolved in three decades and that was by the replacement of the old ink-needle charts with laptop technology. The basics of polygraphy still depends on the ability of a skilled operator to formulate key questions and then interpret the subject's involuntary body reactions -- pulse, respiration, blood pressure, galvanic skin responses, and perspiration.

I see a day when brain mapping and analysis of how a subject responds under electroencephalography (EEG) and function magnetic resonance imaging (fMRI) will replace the current polygraph. The technology is already here and research is underway towards its forensics application.

2. Laser Devices

tech9I think lasers have phenomenal potential in forensics. Currently, laser lighting is used to amplify fingerprint and tool marketing evidence. It's also used in ballistic matching where the old electron-scanning comparison microscopes are being replaced by laser/laptop examiners like the Bullettrax 3D which makes the peaks and valleys of a ballistic engraving show up like satellite ground mapping radar images.

I see a day when forensic investigators will map out a crime scene with hand-held laser devices to perfectly record information which will be transformed into hologram reproductions.

4. Ion-Sniffers

tech10Detection of ions through gas chromatography mass spectrometers has been around fifty plus years and is still used daily in crime labs. What's missing are portable devices to assist in field searches of buildings, vehicles, boats, planes, and the great outdoors. Often investigators know exactly what they're looking for-- a firearm, explosives, contraband, or even a dead body-- but the parameters of the search area turn it into the needle-in-a-haystack scenario.

I see a day when the ionic signature of the article(s) being searched for are then dialed into the device and it zooms right into the location.

5. Satellite Tracking of Dangerous Criminals

tech11Over the past few decades we've got a better handle on controlling violent and prolific offenders through DNA profile banks and ankle bracelets of parolees. We've also had tremendous advances in satellite technology where smart-bombs are delivered down terrorist's chimneys and GPS apps tell you exactly where you are on the planet. We have microchips in everything from our bank cards to our pet Schnauzers and there are more cell phones in Africa than people. What we don't know is where the dangerous .001 percent of the population are and have been.

AB23479I see a day that we'll ditch these guy's rights. We need to protect the 99.999 percent of the population that's at risk. Common sense will prevail and there'll be court orders mandating satellite tracking chips being surgically implanted into dangerous offenders.

I'll check back with you in 2050. It'll be interesting to see what I've missed.

You're a great connector of people, Sue, and I always enjoy the guests you bring to Prose & Cons. Garry - thank you for an absolutely fascinating article. I enjoyed your perspective on both sides of this - the recent advances in criminal and forensic technology and the amazing new possibilities ahead. Thank you both!

Sue Coletta said...

*blushes* Aww, thanks, Eliza!

Fascinating info, Garry. Thanks for lending your expertise. I read recently where police are using DNA to computer model faces in crime analysis and the identification of remains. The tech never stops.

Thanks, Sue.


p.s. Ion sniffing sounds like another cheap high ...

Thanks so much for inviting me on the site, Sue. It's always a pleasure to meet new folks, especially in the crime writing community.

Another thing that's going to be interesting to watch is 3D printers. They may have a real role in forensics.

Something I do is a fair amount of beta reading for crime writers - not for structure or editing - rather for accuracy in investigation procedure, forensics, and ballistics. If anyone wants to shoot me questions or m/s pieces, feel free to contact me at Always glad to help out :)
