Fingerprints are one of the most important pieces of evidence found at a crime scene, which are highly valuable for proving a crime. The optimal utilization of these traces is accompanied by a series of damages. The present research aims to identify the damages associated with the optimal utilization of fingerprints left at the crime scene.

The present research is qualitative with an exploratory approach, and the participants include experts and detectives from the CID police of Tehran. The sample size is theoretically saturated with 20 participants, and the content analysis technique is used for examination.

Using the tripartite model of damage, structural damages are identified with 6 themes: approach, technology, human resources, budget, materials and equipment, and organizational interactions, with 23 (in order of 1, 6, 8, 3, 3, and 2) basic themes. Behavioral damages are identified with 3 themes: job dissatisfaction, training and motivation, and 22 (in order of 10, 8, and 4) basic themes.
