The case was finally over, and after a while, Director Liu, Xiao Li, me, Lao Wolf, and several other criminal investigation captains held a small meeting in the conference room.

Director Liu nodded at me, what I was holding in my hand was the file of the deceased, so I introduced to them and said, "The deceased's name is Li Shuai, a native of Hedong, 28 years old this year, not married, not in a relationship, working as a telemarketer in a small financial company, working overtime in the company on the night of April 26, and then lost contact, the deceased's brother was about to go to the police when we found him, you can speak freely, Where should we start arresting that suspect now? ”

Everyone, look at me, I'll look at you, although this case has made quite good progress so far, but they don't dare to speak first, after all, they are afraid of saying something wrong.

The old wolf and I can be regarded as outsiders, and it has nothing to do with this case, so I said to Director Liu, "Let's check the call list first, find his call list, and we will be able to arrest the suspect soon, of course, if they are connected." ”

Director Liu nodded, indicating that there was no problem with my analysis, and immediately took the file and his phone number and went out.

After coming back a while, he said to us, "I've contacted the telecom department and asked them to check this call list for me, we just have to wait." ”

What followed was an endless wait, and it wasn't until three days later that the list appeared before our eyes.

In fact, it's not that the time is too long, it's not that the technology is too cumbersome, or it needs to be approved, and we have a letter that needs to cooperate with the inquiry, and then report it up little by little, and finally the inquiry, which has been approved, so it took three days.

We thought that by looking up the call list, we would be able to quickly find out who the real murderer was.

But we think too simply, because almost all of Li Shuai's call list is unfamiliar calls.

Director Liu looked at me and the old wolf's frowning brows, and said to the two of us, "There's no way, he's a person who sells financial business and is also a telesalesman, so this is the nature of his job, he needs to call different strangers, and then come to ask for their intentions." ”

I nodded, and I knew that, but it would be a lot more of a lot of work.

After thinking about it, I said to Director Liu, "Call those 40 people, divide them into groups to investigate, and investigate all the strangers on this phone, how many calls did he make that night?" ”

"He made a total of 140 phone calls that night, and if we work in pairs, each person has to investigate an average of 7 groups of people to complete the task, by the way, Director Liu, you talk to the local public security bureaus under you, I hope they can cooperate with our work, after all, it is not easy for us to investigate."

Director Liu nodded, "I know this, I will greet the place below, do you two also want to go?" ”

"Of course, the two of us have to go."

I made a look with the old wolf, and the 140 phone calls, with the help of the police, quickly listed all the information, including name, mailing address, age, etc., all the information was there.

The old wolf and I picked a few random people and set off, the first person was called Wang Jian, an employee of a company.

Working in the city, we quickly found him, with the cooperation of the local police department, of course.

For us, the local police station is still very cooperative, after all, they also know our origin and identity, there is a report from the local police station, of course Wang Jian is also very cooperative with us, and he does not dare not cooperate with us.

In the conference room of his company, Lao Wolf and I sat on one side of the conference table, and this man named Wang Jian sat on the other side of the conference table.

"Where were you on the night of April 26?"

"I've been working in the company, what's wrong?"

Wang Jian looked helpless, and I glanced at the old wolf, not knowing if he was the real murderer.

"Can anyone prove it to you?"

"With our company's surveillance, I worked overtime until two o'clock."

He said this sentence so logically, there is a chance that the monitoring will not need to look at it, otherwise he would not dare to say it so reasonably.

I looked at the old wolf, and the old wolf suddenly remembered something, so he asked Wang Jian, "On the evening of April 26, did you receive a call to promote financial management?" ”

Wang Jian raised his eyes, thought for a while, thought for about ten seconds, and immediately said to us, "Yes, but after I received this call, as soon as I heard that it was financial management, I hung up the phone, after all, I am just an ordinary employee now, how can I have so much money to manage money to engage in finance?" ”

I suddenly took out the file, which had a call record of Li Shuai's phone, and it showed that it had been connected for ten seconds, which was the call to this Wang Jian, and at the same time my eyes focused on another phone.

I looked up at Wang Jian and said, "Okay, you go back first, there's nothing to do with you." ”

Wang Jian was confused and didn't know what was going on, but he still nodded at me and the old wolf, turned away, and went back to continue his work.

The old wolf looked at me with some complaint, and said to me, "Zhou Zheng, why did you put him back?" He's not sure if he's the real murderer? ”

"We've all forgotten a little bit." I said to the old wolf.

The old wolf scratched his head, "What did we forget about that point?" ”

"There were six people on the phone call for less than two minutes, and only one person talked for more than five minutes, do you think the call time will help us determine the real suspect?"

The old wolf's eyes lit up suddenly, and he said to me, "I understand what you mean, Zhou Zheng, if you want to ask her out and commit a crime in a wilderness, you must have a long conversation with him." ”

"That's right, this guy who talked for a total of 6 minutes and 40 seconds, I think he has a big question."

"Who is this man?"

"This person's name is Wang Hao, a 35-year-old married man, let's go ask him."

"yes, where does he work?"

"Also in this city, still a director."

After the two of us left Wang Jian's company, we took a car non-stop and came to Wang Hao's company, where the local police station showed us an investigation order, and we were not afraid that Wang Hao would not help us.

Nearby, we met Wang Hao in the conference room, 35 years old, Si Swenwen, with a three-seven-point head, wearing gold-wire glasses, looking like a successful person.
