Here’s where it gets gross and amazing. Investigators crawl on their hands and knees. They use flashlights at an angle—this makes invisible stuff pop out. Hairs, fibers, even tiny drops of dried juice. You call it dirt; they call it clues.
Funky fact: Luminol is a spray that makes blood glow blue in the dark. It’s like a rave for crime scenes. But it only works if the lights are off, so they do this while standing in pitch-black rooms. Spooky, right?
They also vacuum. Not for dust bunnies, but for trace evidence. The vacuum bag goes into a lab. Imagine the lab tech’s job: “Hey, I found dog hair and glitter.” That could crack the case.
