Powderfinger

Powderfinger by Neumat Ick and Apostrophic Laboratories is a free fingerprint caps display font with a pulpy forensic mood. The letters are built from looping ridge patterns that read like enlarged thumbprints, so the alphabet feels both human and slightly incriminating, with solid black forms breaking through the whorls for a blunt, posterish punch.

That makes it a natural fit for crime zines, mystery covers, Halloween flyers, band posters, and title cards that want a clue-board edge. As a free font, it also works well for short headlines, monograms, and logo experiments where those repeated fingerprint lines can do most of the talking.
