Chapter 1116 - 1047: Winning Amidst Competition
"This area is likely a region Xu Li might have come into contact with. Zone Two." Deputy Captian Qi Yongmiao pointed out the designated area to Jiang Yuan, his tone slightly tense.
Earlier, Jiang Yuan had already extracted a fingerprint from the corpse’s middle finger using the oil lifting technique from Body Number One. Now, if they’re able to find a matching fingerprint from anywhere in the supermarket, it would conclusively prove that Xu Li is the deceased.
A more definitive approach would be to obtain identical DNA. Despite Body Number One being highly decayed, DNA had still been successfully extracted. But since Xu Li was an orphan and the room he rented had been handed over to other tenants, investigators attempted to collect potential DNA samples but found such comparisons to be more challenging.
On the other hand, as a supermarket shelf stocker, Xu Li would have easily left fingerprints behind within the store.
While waiting for Jiang Yuan, Wu Junhao and his team had already narrowed down areas within the store that Xu Li might have interacted with using surveillance footage. However, no matching fingerprints had been found in Zone One.
Qi Yongmiao had held his breath then.
Had it not been Jiang Yuan personally conducting the fingerprint lifting, Qi Yongmiao might have called for someone to redo the process.
Jiang Yuan remained calm as ever. He was taking the matter seriously, so he had come personally to lift the fingerprints. Meanwhile, Liu Jinghui and the others, accompanying him, analyzed the supermarket, considering Xu Li as the victim as they began pondering their next moves.
Zone Two consisted of a shelf at the back of the storage room. Surveillance footage showed that while others had interacted with this spot after Xu Li, the frequency was low, the instances were few, and—more importantly—there was no evidence of wiping, making it conducive to preserving fingerprints.
Jiang Yuan picked up a gray squirrel hair brush, selected silver powder, and meticulously began brushing it onto the dark background of the shelf. A smattering of fingerprints quickly emerged.
