Chapter 595 - 541: Save Traffic
The meeting ended.
Jiang Yuan followed the head of the fourth team, Pang Jidong, straight to the evidence room to collect the main pieces of evidence, namely the entire clothing of all four victims.
Besides that, the forensic science technicians of the day also collected some other evidence from the victims, including tiny grass and tree leaves, soil and fibers found in the victims’ nails, and lubricant residues on the victims’ bodies and underwear, etc., but none were decisive pieces of evidence.
Jiang Yuan didn’t take these pieces of evidence and returned to the laboratory with just the clothing.
Compared to the human body, pollen can remain on textiles for even longer. Especially for certain types of pollen relative to certain textiles, the size may be such that the pollen can even last for several months or longer without being lost.
In fact, the most common application of pollen research is in archaeology. A classic example is when archaeologists found rye, barley, great willowherb, and mugwort pollen from cultivated crops and herbaceous plants in a perfectly preserved Iron Age tomb. The pollen was embedded in the textiles and clearly could not be the result of contamination during burial, but rather was old and preserved within the textiles.
The exoskeleton of pollen, composed of a chitin-like polymer, if magnified to the scale of buildings, would have defensive properties even stronger than the strongest human fortifications, particularly in terms of resilience to natural erosion, being several magnitudes stronger than man-made materials.
Under the stereomicroscope in the Trace Evidence Laboratory, the evidence also proved this point.
There was a significant presence of pollen and spores on each garment.
If not specially cleaned, it’s normal for everyday clothing to be like this—a little tip from this is how to tell if the clothes you buy from Taobao are brand new or returned after being worn. Spend a few hundred yuan to buy a stereomicroscope from Taobao, and you’ll know by the amount of plant pollen in the fibers.
