How King County uses fingerprints to help solve crimes (AD Available)?

King County uses fingerprints like a special kind of clue to help catch people who do bad things.

Imagine you're playing hide-and-seek and leave behind your fingerprint on a door, that’s like leaving a note saying, “I was here!” Now imagine police can read those notes and know exactly who went where.

Every person has a unique set of fingerprints, just like how every kid in class has different handwriting. When someone does something bad, like stealing a bike or breaking into a house, the police might find their fingerprint on something, like a door handle or a glass.

They then compare that print to a big list of fingerprints from people who live in King County, kind of like looking through a giant classroom of handwriting samples to find out who left that note.

If they match a fingerprint to someone already known, maybe a kid who’s been caught before, it's like solving a mystery with just one clue. That person might be the one who did the bad thing!

So, fingerprints help police find out who was at the scene of the crime, like finding a suspect by matching their unique fingerprint to something they touched.
