Chapter 1021 - 955: Dawn_3
"Indeed," Liu Jinghui picked up his cigar again and puffed away for a while: "Actually, no matter which conjecture it is, if the door lock is believed to be opened in an abnormal manner, then it can be interpreted as the work of someone who is not an acquaintance. This could also explain why the surviving little boy said there were two culprits, it’s quite common for burglary or robbery involving a break-in to be committed by multiple people... umm..." Listening attentively, Jiang Yuan turned to Liu Jinghui: "Did you think of something?"
"Thieves working in groups to commit burglaries or robberies may not necessarily be an organized gang, but they are usually experienced. Especially those with the skill to pick locks technically, it is improbable for them to just do one job and then give it up. Even if they’ve killed someone, could they possibly be using a new invention for the crime for the first time and then just abandon it? Thieves don’t have that kind of self-control," Liu Jinghui shook his head. Being a thief is an addictive occupation, once many commit to it, they hardly ever give it up, they are like evergreens in the criminal ecosystem.
As Liu Jinghui pondered, he gave an apologetic smile to Jiang Yuan and said, "I think we might put aside the idea of technical lock-picking for now."
"Alright," Jiang Yuan agreed readily.
"Speaking of which, I’ve got an idea," Liu Jinghui pulled over a whiteboard and said, "If the murderer had duplicates of the key made... I know, you just mentioned that a new key would not have produced so many scratches, but is it possible that the murderer attempted multiple times with different keys... no, he must’ve made multiple attempts, trying once, if it didn’t open, either try again or duplicate another key, then test it?"
Jiang Yuan’s eyes lit up: "Let me have a look."
With that, Jiang Yuan immediately went to retrieve the disassembled lock and started examining the lock cylinder under a magnifying glass.
