The International Association for Identification Conference is the largest in the world for Forensic and Crime Scene professionals and offers a full week packed with scientific and operational lectures, as well as hands-on workshops. This years IAI conference, the 102nd, was held in Atlanta Georgia and we all had a great time catching up with old friends […]
During a recent installation of the VMD360 at the Pinellas County Sheriff’s Office in Largo, Florida we processed several pieces of fabric. One of the pieces considered was a patch from a pair of polyester running shorts (see pic #1) Using just the VMD process, the material was inspected and no obvious signs of fingerprints […]
An example of the benefits of Vacuum Metal Deposition (VMD) over the traditional methods of visualisation of fingerprints with particular reference to new polymer bank notes -Courtesy of Cumbria Constabulary, June 2017 Back story During one evening in 2017, enquiries at an address led to the arrest of three people in relation to the […]
Aim: To test the VMD technique for its ability to develop fingermarks from spent cartridges and bullet casings. Natural and sebaceous marks to be deposited onto bullet/cartridge by a single donor and the bullet/cartridge fired after a set time period (< 5mins, 1 hour, 24 hours, 7 days, 28 days). Gold/Zinc (AuZn), Silver (Ag), […]
10th May 2017 – James Price During recent training with the New Zealand Police, one of their Forensic Scientist successfully developed a great print on a polystyrene cup using a gold/zinc + silver VMD process in their new VMD1260.
6th April 2017 – Ian Harris I recently used one of our VMD360 Latent Fingerprint Development systems to carry out an experiment in order to develop a mark on a sample of leather from a luggage label holder. I placed a natural mark on the leather and the next day developed the mark using Stirling […]
We often ask customers to list a range of problematic substrates that they struggle to develop good fingermarks on. Wood always seems to be high on the list. Here’s an example of good ridge detail developed using a Silver/Zinc VMD process
Here’s a quick update on our research project looking at the effectiveness of different VMD processes in developing fingerprints on the new BoE polymer £5. So far the Gold/Zinc vs Silver/Zinc results are pretty even. Stay tuned for the copper process results..!
Narcotics and money bundles are usually wrapped up in flexible plastic food wrap such as Clingfilm or Saran wrap. This can be particularly difficult to recover prints from, however, once again we have seen much success when processing with VMD. Here are some examples of a few substrates usually used for the packaging and […]
