I am Detective Wu Nan

Xiaodong felt that there were no clues. This was a problem with his observation ability! The reason why Wu Nan was able to solve cases that others could not solve was because he had extraordinary observation skills and unique ideas!

He was a criminal genius in his previous life. He was able to think from the perspective of a criminal. This was his strength.

"Clues? What clues? Where?"Song Xiaodong asked hurriedly.

"For example, call logs……"Wu Nan said.

Song Xiaodong had already walked around the desk and saw that the phone in Wu Nan's hand, which was Lu Shengmei's phone, was connected to the computer with a data cable. Wu Nan had already used the mobile assistant software on the computer to call up the address book in Lu Shengmei's phone.

"What kind of clue is this?……"Song Xiaodong was confused again!

The call information of the deceased’s mobile phone is an important direction of investigation, which is understood by all criminal police. However, not all the call records of the deceased or the victim can reveal anything. In other words, unless the problem is discovered proactively, this is not a point that must be investigated.

Lu Shengmei’s call records cannot be said to be normal, but the abnormality is reasonable!

Because Lu Shengmei often receives debt collection calls, she is often called by numbers from other places such as Kyoto, Guangzhou, Shenzhen, Hangzhou, Shenyang, etc. Of course, there are also calls from local numbers in Mohai, all from online lending platform companies. When

Yang Fengrui investigated the Lu Shengmei case before, because he was able to determine from the beginning that Lu Shengmei committed suicide by jumping into the lake, it was impossible to check all of Lu Shengmei’s call information in terms of the direction of investigation, and it was impossible to check who every person who spoke to Lu Shengmei was. That was unrealistic.

Because it was soon discovered that Lu Shengmei owed a large amount of debt to others, there was no in-depth investigation.

"I have looked at Lu Shengmei's WeChat because she has the habit of regularly clearing her WeChat chat history. This is also mentioned in the archives and in Lu Shengmei's transcript. So I haven't found anything special on her WeChat yet.……"

"As for her call records……"Wu Nan paused before saying,"I can't say how big the problem is for now, but we need to investigate to find out if there is really no problem.……"

Song Xiaodong looked at Wu Nan with a strange expression!

Because he found that Wu Nan's investigation method was similar to luck!

Without finding any suspicious points, investigating a large number of people who had talked to Lu Shengmei would probably result in a waste of manpower and material resources but nothing would be gained. If anything was found, it would be luck!

"There is still time, the communication company should not be closed yet." Wu Nan glanced at the time on the computer, turned his head and said,"How about this, Uncle Song, please go to the communication company and check the information of all the phone owners who have called Lu Shengmei in the past three months.……"

"all?"

"Yes, all of them!"

Song Xiaodong was stunned again. In the past three months, Lu Shengmei had received at least two or three hundred calls and made calls on her own initiative. Even if the duplicates were removed, there would probably be a hundred. Because Lu Shengmei had debts before and often blocked some numbers, the creditors would call her with different numbers. The information of the owners of these numbers was checked.

Then what?

Should we check every one of them? That would be a lot of work?

"……OK……"Song Xiaodong agreed hesitantly. He didn't understand what Wu Nan was going to do, but he would just cooperate with whatever Wu Nan did.

"Huh? Wait a minute?"Song Xiaodong suddenly thought,"Why is it three months, not two months? Isn't it that Lu Shengmei's loan amount surged and she began to withdraw cash? These abnormal situations all happened in the last two months?……"

"Something must have happened to prompt Lu Shengmei to do this. This incident should have happened two months ago, so the scope of the investigation needs to be expanded by one month.……"Wu Nan explained briefly.

It's not that Song Xiaodong is stupid, but that he simply can't keep up with Wu Nan's train of thought.

Wu Nan has already deduced all kinds of possibilities in his mind, which Song Xiaodong can't guess.

For Wu Nan, there are too many clues in this case, so many that any clue Wu Nan picks up may solve the case, so he dares to say that he will give the result in three days. If he can't solve the case in three days, it's really a failure!

The call record information has been retrieved, and there is a printer in the office. The software is used to automatically remove duplicate numbers, and then all the numbers are printed. Song Xiaodong hurriedly left with this list.

It's not troublesome to check the owner's information. You can check it directly by going to the communication company as a policeman, but you have to go a few more times because there is more than one communication company, including China Mobile, China Unicom, and China Telecom.

After Song Xiaodong left.

Wu Nan started to look through Lu Shengmei's mobile phone again.

He was looking at the content of the Moments of a WeChat friend of Lu Shengmei. The user name of this WeChat friend is"White Snow", and this person is annotated by Lu Shengmei as"White Snow Little Cutie"!

This person is Lu Shengmei's best friend, Bai Xue, who has been on leave from Jiaotong University!

According to the transcript of Lu Shengmei's roommate Guan Tingna, she accidentally met the deceased Lu Shengmei and Bai Xue while shopping in Pudong Commercial Street at the end of July during the summer vacation.

In other words, Bai Xue is likely to know where Lu Shengmei worked or what she was doing during the summer vacation.

In Bai Xue's circle of friends, Wu Nan strongly felt what"showing off wealth" means!

This Bai Xue loves to post on WeChat Moments, often showing off her big-brand bags and cosmetics in WeChat Moments, and she loves taking selfies... She is a person with a personality very similar to Lu Shengmei, who loves to spend money and show off.

Wu Nan also found a photo of her and Lu Shengmei in Bai Xue's circle of friends.

The two beautiful girls sat together, with a glass of juice in front of them, and the background was in a high-end restaurant. The text accompanying the photo was: I haven't come out to relax for a long time. Whose girl is so cute, hurry up and take her away~~

The posting time of this WeChat Moments dynamic was August 2.

Wu Nan continued to flip through, and found an earlier WeChat Moments.

He didn't pay so much attention to Bai Xue's updates for no reason, because Bai Xue might really know what Lu Shengmei did during the summer vacation, but Wu Nan didn't ask anyone to check it out right away, or contact her on his own initiative.

Because there is a possibility that Bai Xue knows why Lu Shengmei committed suicide! If you take the initiative to find her, she might explain some of the circumstances, but she might also choose to avoid it!

If she is the type of person who wants to avoid it, it would be bad to find her directly.

Bai Xue posts on WeChat Moments almost every day, more than one.

Wu Nan reads it very carefully.

When I first looked at Bai Xue's WeChat Moments, I found a very interesting situation, that is, after Lu Shengmei's death, that is, after August 22, Bai Xue never updated her WeChat Moments again, not a single one.
