Well if there was a murder weapon there at the death scene, the investigators check the weapon for fingerprints. Same for if there are random murder objects lying around anywhere, they'd check it for fingerprints. I suppose after checking the weapon or murder object, they set it under a scanner that is connected to a computer and it tracks who's fingerprints were last on the murder object and the title and picture of that person comes up.
Hope this helped.
Diets in high in non-starchy vegetables, such as broccoli, spinach, and beans, may help protect against stomach and esophageal cancer. Eating oranges, berries, peas, bell peppers, dark leafy greens and other foods in high vitamin C may also protect against esophageal cancer.
