Half an hour passed, and the security captain did not walk out of the case handling area, that is to say, the evidence against him was enough, and there was only one possibility: Ran Xiaoke pried his mouth open.

Afterwards, everyone praised Ran Xiaoke, and the leaders of the unit also praised Ran Xiaoke by name at the weekly meeting and the daily morning meeting, calling on everyone to learn from him, asking everyone to use their brains more in the case trial, change the traditional concept of coercion and temptation, and start to promote the case trial work from the discovery and collection of evidence clues.

As for how he made the security captain open his mouth, that is, through on-the-spot investigation and analysis, combined with the layout of the basement house and the small number of missing sperm spots on the ground in the dark corner of the backup generator room, he accurately deduced the time, place and process of the crime. As a result, the security captain was dealt a fatal blow, and the series of questions made the security captain unable to parry and resist, and the psychological defense line collapsed in the last ten minutes.

Once the mentality collapses, I don't even know where to start with quibble lies, after all, lying is also a technical job, not to mention facing a crime investigation master like Ran Xiaoke who is extremely responsible for his work. The later transcripts and procedures for going through the case are all mechanical actions, and there is no difficulty, and the police who undertook it quickly handled it.

This is just one of Ran Xiaoke's many wonderful cases.

Continue to return to the confrontation between Ran Xiaoke and He Yuanyuan.

Ran Xiaoke pondered for a moment, the truck driver was cut off his organs, and Lao Du was also cut off his left ear, for this kind of suspect who likes to leave the victim's body parts or objects, he makes up for the traces of psychological trauma very heavy, and alleviates his own pain by letting others experience pain.

There is a theory in physics called the law of conservation of energy. It means that energy is neither created nor disappeared out of thin air, but can only be transferred from one object to another, and the forms of energy can also be converted into each other. Many people think that it is a very mysterious science, and sometimes it is even full of mystery, but in fact, criminology is definitely a science with its own laws. Once you have mastered the rules, you have found the trick to solving the case.

Ran Xiaoke knew that He Yuan's house must have hidden something related to the case, so he asked Zhao Yixin to look at He Yuanyuan and search for it in the house by himself.

The whole room was searched, two bedrooms, a living room, a kitchen and a toilet, very basic decoration, except for simple furniture, that is, a cabinet of books, Ran Xiaoke roughly flipped through it, most of them are books on network technology, there are no ornaments, only a 42-inch oil painting hanging on the wall behind the sofa in the living room.

The bland oil painting, Ran Xiaoke glanced at it, and it didn't attract his attention, what really caught Ran Xiaoke's attention This oil painting was when he came out of the kitchen and walked to the living room again to look around and see if there was anything missing, and his eyes swept over the oil painting again.

He suddenly felt nervous! Zhao Yixin also discovered the master's abnormality, and followed to the wall behind the sofa, or an oil painting on He Yuan's head. Zhao Yixin took a closer look, and couldn't help but grow his eyes!
