Whose fingerprint? (Sidik Jari Siapa yang Punya?)

Still remember the songs that have the words' ‘Nona manis siapa yang punya?’ If it was, easy answer, there is in the song itself. But if a crime occurs murder or robbery, the police officer was busy looking for the perpetrator's fingerprints left at the scene. Having met a few fingerprints and the question as the title above, the answer would be hard to find.

To match fingerprints found at the scene, the police would have to have a fingerprint database population. Did the police have it? I am sure, only a small portion. Not all residents enrolled in the police fingerprinted. So there is a possibility if the fingerprints found at the scene, the police officer had no comparison data.
How is the solution? Let you use your own thought.
