    In a violent or suspicious death, the PNP (National Police of Peru) collects evidence found at the scene using standardized methods for its collection, safeguarding, and protection until analysis. However, there is no technique for evidence search using a metal detector. Therefore, the objective of the study is to assess the effectiveness of the Garrett ACE 250 metal detector in the search for conductive evidence in investigations of violent or suspicious deaths. A total of 384 sweeps were made with the metal detector on different soil types, searching for common conductive evidence such as: projectiles (bullets and cartridges), sharp objects (piercing – verduguillo), (cutting – knife), blunt objects (hammer, pistol). The research established values for each level of effectiveness to be evaluated: High, Intermediate, and Low, and assessed all searches based on soil type, depth, and evidence type, highlighting the highest levels achieved as follows: The effectiveness levels of the Garrett ACE 250 metal detector in clay soil were High at 75%. At a depth of up to 10 cm, a 100% high effectiveness was achieved, and for blunt evidence (hammer and pistol), 75% high effectiveness was achieved.
