"Is it possible to think that something happened at the identification center that caused Zhu Yajun to give up the diary?"

"Or should I say this: There are some things that she cannot record in her diary, dare not, and cannot leave information on paper?"

"Our investigation must turn to Zhu Yajun's family, focusing on phone and WeChat numbers, as well as contact records during this period."

The troops were divided into two groups. Zhang Yixuan was responsible for investigating Zhu Yajun's family, while Hu Pingtao went to the telecommunications bureau.

At noon, the two parties briefly discussed their respective investigation results on the phone.

Zhang Yixuan did not gain much here. There were many men who had relationships with Zhu Yajun, and her family was not very clear about this. Although she knew a few, it was of little help to the case.

The same goes for Hu Pingtao.

On the day of the incident, I checked all the numbers Zhu Yajun dialed and dialed on his cell phone. Except for work matters, none of them had anything to do with the case.

The most important factor is also the mobile phone number used during the locked time period of the crime, which was registered in a remote county in Jiangdong Province.

Although each ID card can only register and purchase one mobile phone number, before the relevant regulations were implemented, the domestic mobile phone market was already in chaos. The phenomenon of using other people's ID cards to buy, exchange and buy more frequently occurred, resulting in many people later using various channels to hold the phone number.

There are multiple mobile phone cards.

The murderer obviously took advantage of this loophole.

Zhang Yixuan felt a little downcast. He held his mobile phone in a secluded corner and turned on the speakerphone. He said tiredly: "I have been busy all morning, but there are no results. Yesterday I praised Haikou in front of the king team... This time is difficult.

"

Hu Pingtao's laughter came from the other side of the microphone: "Giving up defeat so quickly? This is not like your style!"

Zhang Yixuan smiled bitterly and said: "Don't tease me, I know you must have a back-up plan."

Hu Pingtao said seriously: "You can think of everything I can think of. In fact, it is not without gain from the telecommunications bureau. It is not in vain."

Zhang Yixuan's eyes lit up: "Are you referring to the WeChat conversation record between Zhu Yajun and the murderer?"

Hu Pingtao's voice was full of comfort: "I will forward the conversation record to you later. You will understand after reading it."

…

A few minutes later, Zhang Yixuan had read the forwarded part and made a quick judgment.

He called Hu Pingtao again and said excitedly: "It seems that the key to this case still lies with the Alice Identification Center."

Hu Pingtao smiled happily on the phone: "I'm on my way to the bureau. Brother Wang has asked someone to prepare surveillance video photos of the suspect. Come back first, let's collect the information and go to the identification center in the afternoon.
