And directly under the chair in the living room, Lu Chuan discovered a series of irregular barefoot footprints.
Those should have been left when Lin Ting was being abused while sitting on the chair.
So, the barefoot footprints should belong to Lin Ting, whose footprints are the others?
The killer is unlikely to change slippers.
So the slipper footprints are most likely also left by Lin Ting, or by the man who occasionally stayed at Lin Ting's place.
But the footprints with shoes are most likely the killer's!
Apart from the footprints on the ground, there are also many fingerprints at the scene.
Lu Chuan didn't have a UV light at hand just now, so he could only observe roughly; fingerprints were found on both the fruit knife and the chair.
Now, with the fluorescence light, it can be said that they are densely packed.
This case, judging by the victim's living situation and the conditions at the scene, currently has two hypotheses.
