Vacuum Metal Deposition Webinar

NIJ's Forensic Science Technology Center or Excellence (through RTI International) will host a free webinar October 22, 2014 on Vacuum Metal Deposition.


Vacuum Metal Deposition (VMD) was first discovered as a potential process for latent print development in 1964. Since then, extensive published research on processing techniques and equipment has been developed. This presentation will review the history of the process, the equipment, selected metals used for latent print development, vacuum chamber operations, current research, and resources.

The 60-minute webinar will be hosted by forensic technician Brian Orr, a Certified Latent Print Examiner, evidence photographer, and laboratory technician with more than 25 years of experience.

Lifting Latent Fingerprints from Difficult Surfaces

ALMOST ANYONE can find, process, and lift a latent print that happens to be in a logical and obvious place like a door handle, a beer can, or a butcher knife. But sometimes, a latent print is not just sitting there in a logical and obvious place. Sometimes, you have to use your imagination to find the print and your skills to lift it.
