Footprint Identification and Analysis, ideally, involves analyzing and identifying footprints on soft surfaces like sandy or muddy grounds.
Footprints left on such soft carriers are clear and three-dimensional, allowing for a more accurate analysis of the physical characteristics of the footprint owner.
In reality, however, such clear footprints at crime scenes are only possible in outdoor crime scenes.
At indoor crime scenes, most floors are made of boards, tiles, or cement, with few soft surfaces, so the clarity of the footprints might be enough, but they lack a strong three-dimensional effect.
Even more challenging is when the criminal disguises their actual footprint features by altering their normal shoe size.
Lu Chuan had encountered various types of footprints before, but today was the first time experiencing a non-footprint footprint.
