Clearwater, FL – Detectives in Pinellas County are using gold in a new way — not as currency, but as a powerful forensic tool to uncover hidden fingerprints on tough surfaces.
According to the Pinellas County Sheriff’s Office, their Vacuum Metal Deposition (VMD) Chamber uses just 4.4 milligrams of gold per process to detect fingerprints on materials like fabric, currency, or items exposed to water or soil. The gold adheres to surfaces except the print itself, revealing a detailed negative image that preserves DNA for additional testing.
The Sheriff’s Office said this method works where traditional fingerprint powder fails, including on porous or weathered items. A follow-up process using zinc enhances visibility, allowing specialists to target exact areas for further analysis instead of processing entire surfaces.
Officials noted that while superglue fuming remains standard for non-porous materials like glass, VMD is more sensitive and works on older or degraded evidence. The technology has already improved efficiency in complex cases involving large items such as bedsheets or crime scene debris.
Authorities also reminded the public that finding fingerprints or DNA doesn’t automatically make someone a suspect. Each finding must be verified within the broader context of an investigation.
