Wiping the gun clean has long been considered best practice for villains but may soon become a quaint custom that will ultimately prove fruitless. Researchers have developed a method to ‘visualize fingerprints’ even after the print itself has been removed by measuring the corrosion of the surface by deposits from the fingerprints. The technique can enhance – after firing– a fingerprint that has been deposited on a small caliberhttp://en.wikipedia.org/wiki/Caliber metal cartridge case before it is fired. The technique promises the ability to reopen many cases and solve cold cases around the world because the “underlying print never disappears” according to the scientists.

The Forensic Research Centre at the University of Leicester (UK) develops new ways of taking evidence from a crime scenehttp://en.wikipedia.org/wiki/Crime_scene . Already world-leading in such areas as using X-Rays or electrically charging metal surfaces for fingerprint enhancement , they have now developed an entirely new way of detecting fingerprints – great fodder for Crime Scene Investigation fans … and one that could realistically result in thousands of cold cases being reopened around the world.

Or, wiping the gun down with fine emory cloth. If stainless, nothing further needed. If blued, the perp may want to cold blue it.
I saw an episode of Forensic files where they got DNA from the inside of the fingertip of a latex glove found in the trunk of a suspect’s car.They matched the DNA to the suspect and he got life for murder.
Gloves may not work either,unless the perp is really careful to not leave any gloves-or parts of them-behind.
But the technology realizes finger prints on left on the cartridge when loading.
Very cool
Note to self:
Remember to wear gloves.
Remember to wear gloves.
...or use a revolver.
“Wiping the gun clean has long been considered best practice for villains”
Memo to self: wear gloves when loading up to commit a crime.
Great. This will result in swift sure death penalty executions like the vast majority of the U.S. public wants, right?
There must be more to this story. I would think it likely that a rubber glove found in my possession would have my DNA on it.
It would be another story if it also had the victim's DNA on it or some evidence of the gun as well.
Canada actually broke ground in this area of forensic science.
then when the rounds are fired, prints can be lifted from the expended round.
Thanks. From now on, I’ll wear gloves.
All the more reason to use a revolver.
or load with gloves. why is this treated as an innovation? from what i understand, this has been around for a while.
Great, now if they could just find a way to give harsh penalties to violent repeat criminals, we might be getting somewhere.
If the weapon is even found the villain messed up in his planning.
“The term epidural is often short for epidural anesthesia, a form of regional anesthesia involving injection of drugs through a catheter placed into the epidural space. The injection can cause both a loss of sensation (anaesthesia) and a loss of pain (analgesia), by blocking the transmission of signals through nerves in or near the spinal cord.”
Don’t leave your cartridge cases around the OB department!
