In a significant development for the unsolved Sophie Toscan du Plantier murder, US forensic experts from M-Vac Systems, led by Jared Bradley, collaborated with Forensic Science Ireland (FSI) in July/August 2025 using advanced wet vacuum DNA technology to re-test old evidence from the 1996 crime scene (rocks, concrete block). The aim was to recover new DNA, potentially the killer’s, from hard-to-reach spots, leading to hopes for a breakthrough in the nearly 30-year-old case, with results eagerly awaited by Gardai. 

:US Experts: Jared Bradley’s M-Vac Systems (Utah, USA) brought their specialized DNA collection tech.FSI Collaboration: They worked alongside Forensic Science Ireland (FSI) on the physical evidence.Technology: The M-Vac system uses a spray and vacuum method to lift cells from rough surfaces where traditional swabbing failed.Evidence: Key items tested were bloodstained rocks and a concrete block used as potential weapons.Goal: To find new DNA, potentially the killer’s, to finally solve the murder of Sophie Toscan du Plantier.Status: As of late 2025, Gardai and investigators were awaiting the results from these groundbreaking tests. 

This effort marks a major push by Irish authorities to use cutting-edge methods on old evidence to bring closure to the high-profile cold case.
