Returning to the team with the few pieces of evidence they had found, Crow and Haizi had already returned.

It turned out that Ni Xiaomei accompanied her mother to travel to Hong Kong with a tour group five days ago, and she didn't show up in S City during this time.

Moreover, the Exit and Entry Management Department of the S City Public Security Bureau also found her exit record five days ago, and so far there is no entry record for her.

Obviously, whether Ling Yunyan committed suicide or killed him, Ni Xiaomei had an alibi, and it was possible that she didn't know anything about it.

While asking the comrades of the electronic technology department of the bureau to handle Ling Yunyan's computer technically, Yang Zi arranged for Xiaopang and Crow to take the credit card and the key, as well as the bank cards found in Ling Yunyan's wallet, to various banks in S City for verification.

Then he arranged for Haizi to take Ling Yunyan's ID card to the mobile company, Unicom and the telecommunications bureau to check whether there was a relevant communication number.

After all, it is now an information society, and according to Ling Yunyan's analysis of social roles, it is impossible for him not to use communication tools such as mobile phones.

Since no communication tools such as mobile phones have been found at the scene where his body was found or in his residence, it is clear that there is only one situation: there are some phone numbers or call logs on the mobile phone that do not want to be known.

It is possible that Ling Yunyan threw her phone in an unknown place for some reason before committing suicide, and it is more likely that Ling Yunyan's murderer deliberately took his phone away to hide some information on the phone that was not beneficial to him.

Soon, teammates on both sides had news back.

Xiaopang and Crow went to the Industrial and Commercial Bank of China S City Branch to show the relevant documents, and asked the bank staff to help find the account of the card.

According to the data provided by the bank, the balance on the card is 10.75 million yuan, and they have printed out all the details of the account and brought it back.

Looking at the current information and the balance displayed in this account, Haizi was dumbfounded and said, "Obediently, he is really rich." Is the income level of the attending physicians in our city so high? ”

Looking carefully at those exchange information, it is obvious that this card is basically only in and out, the time of deposit is not necessarily, and the amount is not fixed, but the smallest one is 50,000 yuan, and the largest one is 500,000 yuan, most of which are deposited in the same account by transfer, and a small number are deposited in cash at the counter.

Xiaopang and the others asked the bank staff about the incoming account at the bank, and this account was not opened in any bank in China, that is to say, this account was an international account set up overseas, and the money was remitted into his card from abroad.

If you want to know the attribution of this account, you can only go to the People's Bank of China S City Branch to make an inquiry.

Who owns this offshore account? What kind of transaction or agreement does he have with the owner of this account? Why did Ling Yunyan send so much money through this account in just a few years?

Everyone looked at this ordinary printing paper, looked at such a huge number on it, and then thought of Ling Yunyan's profession, even if the sum of all the doctor's salaries and bonuses plus subsidies under various names was much higher than that of ordinary units, but such a large amount of his salary was unattainable in any case, and it was seriously inconsistent with his profession.

Of course, there is a possibility that he received black money from patients, or worked for other hospitals outside, and it is not excluded that there is another possibility, that is, the money was remitted to Ling Yunyan by Ni Xiaomei's father.

But in any case, the mystery left behind by the dead Dr. Ling makes people wonder more and more about what he died for.

In addition, the golden key was also confirmed to be the key to the safe deposit box provided by ICBC to the customer, but since the bank safe was set by the customer when storing things, the bank could not open the safe without knowing the customer's password, so there was no way to know what important things Ling Yunyan had put in the bank safe.

As for the other three bank cards found in his wallet, they belonged to three different banks. One is a commercial bank, which has been confirmed to be a salary card issued by the First People's Hospital of S City, and the balance in it is not much, only a few hundred yuan; One is from China Construction Bank, and the duplex house purchased by Ling Yunyan is a personal housing mortgage loan handled by China Construction Bank, and this bank card is used for loan repayment; There is also a green card for postal savings, and after investigating with the post office, Ling Yunyan will remit 1,000 yuan to her hometown every month through this card.

Haizi investigated and collected evidence from the business halls of three communication companies, including China Mobile, China Unicom, and Telecom, and found two mobile phone numbers registered with Ling Yunyan's ID card at the S City Branch of China Mobile Communications Company, and he had asked the staff of the mobile company to print out the call records of these two numbers within a month.

However, in China Unicom and China Telecom, the S City Branches of China Unicom and China Telecom, no CDMA number or PHS or fixed telephone number registered with Lingyunyan's ID card were found.

After arranging for Fatty and Crow to go to the S City Branch of the People's Bank of China to check the ownership of the suspicious account, Yang Zi and Haizi met head to head and picked up the call records and studied them.

The two mobile phone numbers under Ling Yunyan's name, one is used more frequently, but the incoming and outgoing numbers are not necessarily, there is a landline number that often calls in the call record, Yang Zi motioned to Haizi to dial the phone on the table, and the phone was quickly connected: "Hello." This is a doctor in the city, please press the extension number, please dial 0 to check the number. From this point of view, this mobile phone number is often used by him in his daily life.

Looking at the call history of another number, there are only a few calls in a month. However, it is worth noting that the phone is contacted by the same mobile phone number, as if there is a one-line connection between the two.

Most of the time, Ling Yunyan's mobile phone dialed out to the other party, and the call time was not long, on average about 1-2 minutes. But at 14:25 p.m. on the day of his death, he dialed the other party's number, and the call lasted 1 minute and 23 seconds; And 3 hours later, at 17:25, the other party called his number, and the call time was 2 minutes and 51 seconds.

Yang Zi picked up the phone and dialed the mobile phone number, but a voice prompt came from the phone: "I'm sorry, the user you dialed has been stopped." ”

Almost at the same moment, Yang Zi and Hai Zi exchanged glances with each other, and they both saw from each other's eyes that the thoughts in the hearts of the two people were the same, and there must be something wrong with this mobile phone number. Without Yang Zi's explanation, Haizi had already gotten up and picked up the notebook that recorded the number, and then left him a sentence while walking out: "Team Yang, I'll go to the mobile company to check again." ”

At this moment, the phone on Yang Zi's desk rang, and it was Zhang Xing from the Electronic Technology Department who called, and Yang Zi asked him to help decipher the password on Ling Yunyan's laptop.

Zhang Xing told Yang Zi that the computer had been turned on and asked Yang Zi to go over and take a look. Yang Zi hurriedly walked towards the electronic technology department, and on the way, she met Lin Shanshan who came to care about the progress of the case, so he beckoned her to go with her.
