Fingerprints Know and See Everything … and They’re Gonna Tell!
What if police could learn the habits, lifestyles, and even which type of shampoos, deodorants, drugs and the foods consumed by criminals? Would that sort of information be useful in a criminal investigation?
Well, duh … Certainly it could be helpful to know this sort of information. After all, suppose a murder occurs on your beat. At the scene you discover the following:
- The killer eats garlic.
- The killer touched a condom.
- The killer uses SPURT shampoo
- The killer uses Funkaway deodorant.
Since you’ve patrolled this beat for 36 years you know a crook who regularly dines at Gambillo’s Garlic House and Diva Drag Queen Review (home of the tastiest garlic ice cream on the planet). Oh, and it is widely known on the streets that Gary Gambillio, the proprietor, is a cocaine dealer who also runs a brothel in the rear of the restaurant.
So how did your stellar detecting skills help you learn of the killer’s use of SPURT, a flowery new shampoo? What about Funkaway, the deodorant that fights underarm nastiness for up to 87 hours? The garlic. Cocaine? A condom? How did you know?
Easy … you found a single fingerprint and on that print you found traces of garlic, condom lubricant, the shampoo, cocaine use (not merely handling, but actual consumption of the drug), the deodorant and, well, a lot more.
Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging and Profiling
Yes, scientists have discovered a method of examining fingerprints that helps map a criminal’s lifestyle. The technology—Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging and Profiling (MALDI-MSI and MALDI-MSP)— was developed by Sheffield Hallam University researchers.
Using the technology, officials are able to track a criminal’s activities and even quite a bit of his lifestyle prior to committing the crime. And the information is all there for the taking, sitting along fingerprint ridges.
So, when you go to Mr. Bad Guy’s home to chat about the murder that occurred last night, the one in the apartment next door to the home of Mr. Bad Guy, you notice a grocery receipt on the coffee table. Item number one – Funkaway deodorant. Item two – A jumbo size bottle of SPURT. Next to the receipt is a matchbook from Gambillo’s Garlic House and Diva Drag Queen Review. Not a foot away is package of new condoms and small bag of cocaine.
Therefore, being an extremely savvy detective, you allow the loop inside your mind to play. SPURT, Funkaway, garlic, cocaine, condom, murder next door … DING, DING, DING, we have a killer!
My apologies for posting twice. I’m at Magna Cum Murder and posting from my iPad. I’m not used to using it for the ‘net and things look a little different.
Holy cow, that is amazing! I imagine that the the MALDI-MSI and MALDI-MSP expensive. Do many departments have them? How big are they (fridge size, desktop size, etc.)?

Such fascinating little details that do the bad guys in. If the criminals ever figure it all out are we in trouble?
Ah, but wouldn’t possessions of all those items be circumstantial evidence? You’d still have to prove he dunnit, wouldn’t you?
Of course, but like all cases it’s the totality of evidence and circumstances that add up to proof, or to at least point investigators in the direction of a suspect. All of those items together are pretty good indicators that Mr. Bad Guy was at the crime scene. Remember, too, his fingerprint is at the crime scene and all the information gathered from the print points to this guy. So, they compare his print to the print at the scene, and well … case closed. Unless, of course, there’s a logical explanation that Mr. Bad Guy’s print was on the murder weapon or somewhere near the body, etc.
In other words, all the information obtained from the prints are like arrows pointing to a suspect. Once police have that to go on all they need to do is find that suspect and to gather as much evidence as they can along the way.
I love these kinds of articles from you. They give me good idea for things I can work into future stories. I’ll be sure to keep this one!
I’m glad you find them useful. I’m also pleased that you ask questions. Keeps me on my toes.
