Wen Yan himself is a professor of psychology, for any case, he wants to participate in or look through the case file, it is a simple matter, coupled with the strong invitation of Officer Shi, Wen Yan participated in this case.

So Su Tong called Wen Yan directly, coquettishly tricked him, asked him to take over the case, and helped her get the latest evidence.

Wen Yan had no way to deal with him, and he also had some friendship with Wan Qian, so he agreed. Take the initiative to go to the police station of the subdivision to find out the current situation of the whole case.

In particular, the forensic report is particularly important. Gu Ran died of excessive blood loss, and when he fell downstairs, he collided twice in succession.

The second collision was obviously much heavier than the first, but Wen Yan looked at the wound and felt a little strange.

He went to the scene again, did many tests in succession, and found an impossible problem.

Based on the situation that Wan Qian and Gu Ran fell down together at that time, maybe he would have been hit many times, but it could not be heavier than the first time, judging from the bloodstains left at the scene.

It is also obvious that the heavy blow to the back of Gu Ran's head that fell to the ground was the most serious. But why was there a second, stronger impact?

Was it because Wan Qian fell on Gu Ran's body and caused him more serious injuries?

Wen Yan felt that this possibility was very rare, and after many times of analysis and inference from the wounds on Wen Yan's body, he was finally very sure that the second impact on Gu Ran's body was actually not an accident, but man-made.

The other party smashed Gu Ran's previous wound again, completely injuring his head, causing bleeding nonstop. Eventually, he died of blood loss.

The footprints collected at the scene were not occupied by anyone else. In other words, if there is really a third person, the other party is premeditated, so it will be done without leakage.

But if this person really exists, who will it be?

Is it Han Jingtian, Gu Yan, or Gu Wenrong?

After Officer Shi's investigation, all three of them had alibi evidence, that is, the suspects were not the three of them. Who else would that be?

Wen Yan brought all the information to Su Tong's house, and the two began to think together, who else would there be?

After thinking for a while, Wen Yan finally spoke. "In fact, this case is not complicated, and judging from the current situation, it is obvious that Gu Ran was murdered."

"Gu Ran's social background is actually very simple, if someone really wants to kill him, the most likely thing is to compete with his brothers and sisters for the family property."

"Gu Wenrong is too simple-minded, if he wants to make a move on Gu Ran, he will definitely choose to find someone to kill him directly, so it shouldn't be him."

"Most likely, it is Gu Yan and Han Jingtian. The two of them are too simple to find any clues about them, and we don't even know whether the two of them are united or independent. ”

"I am now seventy percent sure that the people who put Gu Ran to death must be Gu Yan and Han Jingtian. It's just that with the care of the two of them, I don't think they're going to delegate someone else to show up on the scene. ”

"Give Gu Ran a second heavy blow, so according to the normal situation, they must have appeared there in person at that time. But both of them have evidence of an alibi, and for a while, it makes it difficult for us to suspect them. ”

Wen Yan touched his chin, looked at the photos of Gu Yan and Han Jingtian, and had to be vigilant, feeling that these two people were really not simple.

"Brother Yan, according to what you mean, there must be something wrong with their time witnesses?"

Wen Yan shook his head and said. "No, it's no problem, I've checked, all the video surveillance is real."

"After Han Jingtian was sent to the company at home, Wan Qian went directly to the airport, and there was video surveillance along the way, so it was impossible to fake it."

"And Gu Yan is having a video conference, and the whole process is recorded, and there can be no fake."

So both have evidence of an alibi. But if it weren't for these two people, Wen Yan really couldn't think of anyone else who would want Gu Ran's life.

Listening to Wen Yan's words, Su Tong frowned. "Brother Yan, what do you mean? Do you suspect the two of them? At the same time, you conclude that their evidence is correct. Aren't you contradicting yourself? ”

Wen Yan fell into deep thought again, and looked at the two volumes of surveillance video over and over again, which were the video evidence of Han Jingtian and Gu Yan when they were not present on the day of the crime.

He always felt that something was wrong, but for a while, he couldn't figure it out. So, he just stared blankly like that, until a long time, his eyes, which were almost frozen, suddenly lit up.

"I see."

Su Tong looked at Wen Yan with excitement on his face. "What's wrong? Brother Yan, do you see anything wrong? ”

Wen Yan pointed to Gu Yan's video and said: "She was holding an international video conference at the time, and the time difference between the other party's country and my country was just two hours. This should be the other party's time, 9:30, in fact, it is only 7:30 here. ”

That is, it was not yet nine o'clock when the whole meeting ended. After nine o'clock, Gu Yan only said that she was in the office and did not have time to witness, so it was very likely that she took advantage of this time to come to the scene of the murder. ”

Gu's headquarters is actually not far from where Gu Ran works, only two streets, not to mention driving, even walking in less than half an hour.

Therefore, if Gu Yan used other more convenient tools, her speed would definitely be faster!

After listening to Wen Yan's explanation, Su Tong also played this video and watched it carefully. Sure enough, it was found that the time displayed on the screen was most likely the other party's time, that is, Gu Yan had no evidence of an alibi.

Su Tong stood up excitedly, "Brother Yan, I want to tell Officer Shi about this important discovery immediately." ”

Wen Yan grabbed her and shook her head, "Even if there is this evidence, I'm afraid she won't admit it." The most important thing for us now is to find the murder weapon. ”

The thing that caused powerful physical damage to Gu Ran's head must have been a large stone or brick, but nothing was found at the scene. Apparently taken away by the murderer.

If this murderer is really Gu Yan, then where will she take the murder weapon?

However, Wen Yan is only responsible for analysis, and the real investigation is still handed over to the police. After having these clues, Officer Shi immediately brought Gu Yan for questioning.

Gu Yan is not surprised by this woman. I admit it very frankly. "It's true that the time on the video is not Beijing time. However, you didn't say that you need Beijing time, did you? ”

Several policemen choked on the spot and could not spit out a word. It turns out that this elite strong woman should not raise her face and be more superior.
