"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.
