crime profiler in the dark

"My job is actually more of a criminal profile."

"Criminal profiling... I've heard of it, but it doesn't seem to be of much substantive help to the case, right? For example, even if you profile the murderer, can it be used as a court basis? Now our judges should be more You like physical evidence that you can see and touch, right?" Sergeant Deng said.

"It is true. Profile has many limitations, but it can narrow down the scope of suspects through the scene of the crime. To tell you the truth, I actually got a general understanding of the crime through other colleagues. The truth behind the crime The murderer was not Yi Yunzhao, otherwise, based on his criminal investigation experience, how could he have stayed at the scene of the crime for several hours without leaving? There are also numbers left by the deceased at the scene, why didn't he destroy them? So the real murderer There must be someone else." Bai Haolin knew that Sergeant Deng was wary of himself who came to visit suddenly, so he simply expressed his thoughts.

"I agree with what you said, but it doesn't explain the existence of the secret room. This is also evidence that Yi Yunzhao is identified as the murderer." Sergeant Deng spread his hands, expressing helplessness.

"The crime scene is still under lockdown, right? Can you take me to have a look, maybe from a psychological point of view, I can see some thoughts of the murderer." Bai Haolin looked earnestly at Sergeant Deng.

Sergeant Deng hesitated for a moment, feeling that the case was now at a bottleneck, he asked Bai Haolin to see that there was no loss, so he agreed.

China Merchants Bureau, Commercial Information Investigation Division

There is also a yellow warning tape at the door of the office, warning people around not to enter.In fact, after the supporting police officers took pictures and collected the evidence at the scene, the scene was handed over to China Merchants. However, China Merchants did not allow the Commercial Information Investigation Department to resume work, and it still maintained its original appearance.

Sergeant Deng led Bai Haolin into Wu Tian's office. The blood had been wiped clean, and the phone had been put back on the table, as if nothing had happened.

"This is the photo at that time." Sergeant Deng handed the photo taken by the assistant police to Bai Haolin.

The photos at the scene were taken very carefully. The corpses were taken from different angles. Whenever there was something unusual, the assistant police who took the photos faithfully recorded it, so that Bai Haolin didn't have to work hard to figure it out roughly. At that time, when looking at the photos, he noticed Wu Tian’s keys in one of the photos. There were seven or eight of Wu Tian’s keys, and one of them had a sticker with the three words "office" on it. Bai Haolin always felt that there was something wrong with the blackened strip, but he couldn't explain why, so he asked Sergeant Deng:

"Are there only two keys to the office?"

"Well, one is on Wu Tian's body, and the other is in the cleaning room. Only the cleaning workers have the keys to the cleaning room." Sergeant Deng knew what Bai Haolin wanted to ask, and said, "We have already checked the cleaning workers. , no one has lost or lent a key in the past six months."

Indeed, borrowing the key of the cleaning room from the cleaning workers in the capacity of Deputy Director Li Ying will definitely attract attention. The problem is still with Wu Tian, ​​but borrowing the key from a person is very suspicious in itself. How could Wu Tian not attract attention? What about vigilance?Or did Li Ying secretly match it without him noticing?If so, how to prove it? !

Bai Haolin stepped back to the door, looked at the structure of the lock, and looked at the edge, but unfortunately, he found no suspicious traces.

Sergeant Deng saw Bai Haolin staring at the photo lost in thought, knowing that he also had doubts about the secret room, so he didn't make a sound, but silently took out a cigarette and played with it in his hand.

"Officer Deng, the deceased left a string of numbers on the phone. Has the meaning of the numbers been found out?"

"We have consulted decryption experts, but this string of numbers seems to be random and has no meaning." Sergeant Deng sighed softly, "He is almost dead, why bother to leave the mysterious numbers behind?" , Just write us the name of the murderer!"

Sergeant Deng's words were like a stone falling into a calm lake, and Bai Haolin's heart was aroused with waves of inspiration: "If, if he didn't think too complicated, but, but we think things clearly Is it too complicated?!"

"Huh?!" Sergeant Deng looked at Bai Haolin, feeling that his point of view was a bit interesting.

Bai Haolin hurriedly found out the photos with the keys, followed the train of thought Sergeant Deng said just now, and said, "Wu Tian has so many keys, why is it only the office keys with a small identification cloth on them?!"

Sergeant Deng is also a smart person. After listening to Bai Haolin's words, he suddenly understood. He walked to Bai Haolin's side and looked at the photo: "Yes, usually there are two keys with very similar shapes. Put a mark for easy identification." But the shape and color of the other keys in the photo are not the same as the keys in the office. Since it is a key that is easy to identify, why does Wu Tian stick a small cloth strip? !In other words, Wu Tian must have lost another key!
