"Where the hell is ......?"

Bai Yaqing didn't understand, what went wrong......

Zhang Zijun was worried that if Bai Yaqing continued to think like this, would there be something wrong with his brain......

"Xiaoqing, why don't you take a rest first, and this case will not be investigated for half an hour......" Zhang Zijun gently placed his right hand on her back, and his tone was gentle and concerned......

"No, something must have gone wrong...... Can you find their chat history? ”

"This is only possible from the operator's server, and we can only check the last week's worth here." Zhang Jiahua explained.

"You check the identity information of these five women, I want to investigate them in detail."

Bai Yaqing's order is undoubtedly a big workload.

Now there is only one more possible inference, that is, the information of the five of them was stolen, or the account was stolen. There is another way, that is, whether these five people have a common friend, check from this common friend......

Another two hours passed, and Zhang Jiahua matched five people through a population system developed by himself.

"It's strange that two people have died, and three more, one is married, and one is ...... abroad."

That is, the remaining one is single, and the one who is married has another social account.

"Liu Fei, I'll leave this matter to you to investigate." Bai Yaqing said to Liu Fei earnestly, give him this heavy task.

Although this task will be a little embarrassing for him to go alone, after all, one of them is married, and it is indeed a little embarrassing to ask others if they have dated other men on their social accounts.

However, Liu Fei also lived up to expectations and found it back.

……………………

In the evening, Liu Fei returned to the office of the serious case group after the investigation.

"Team leader, I found out, the social accounts of the two were stolen not long ago."

The married beauty, because it was the trumpet she used before marriage, didn't care, but it was more troublesome for another single person, and she reapplied for an account.

"Okay! Zhang Jiahua, Zhang Zijun, the two of you immediately check the login IP addresses of these five accounts. ”

After getting this news, Bai Yaqing was finally able to have some leaders.

The accounts of these two people have been stolen, so it is very likely that the other three have also been stolen, not to mention that two more people have passed away, isn't it easier to steal these accounts? As long as you check the login IP addresses of these five accounts, you may be able to find out something suspicious.

Half an hour later, the IP address was found out by connecting with the cloud server of the social platform company.

"It's all IP addresses in the same area as the victim's area." Zhang Jiahua said.

"Check it out earlier! The IP address in the same area is most likely from before the killing. Bai Yaqing analyzed.

With only three days between the five victims, there is no reason to say that there would be only one IP address.

For example, if victim 5 knew the murderer more than a month ago, and victim 4 was half a month ago, the IP address will not be the same.

Zhang Jiahua just did a cursory check of the recent one, and after a careful check, it is true. The five accounts and the victim's IP addresses in the same area were the day before they were killed, or a few hours before, and even further, in City A.

In other words, the murderer is looking for a target in City A......
