In order to eliminate the witness testimony, the inhumane murderer infiltrated Niu's house and forced Miss Shen to take cyanide and die violently.

Now that Niu Dali and Miss Shen, two innocent people, died at the hands of the hidden agents, Lei Yunfeng left the hospital with a heavy heart and drove back to the unit.

When he drove to a distance of more than 100 meters from the unit, he accidentally found a public telephone booth on the side of the road, and subconsciously stopped the car and sat in the car, looking at the phone booth.

This phone booth is set up in a place with a lot of people, and it is only more than 100 meters away from the telecommunications office, Lei Yunfeng has an inexplicable feeling, he wants to walk into the phone booth to see, and this idea is getting stronger and stronger.

He jumped out of the car and walked to the public phone booth, pushed the door in, circled around the phone booth, inspected it thoroughly, and finally took a look at the public phone number.

He picked up the phone and dialed the switchboard of the telephone bureau and asked him to receive the phone from Director Liu.

After the phone was connected, Lei Yunfeng said: "Director Liu, I'm Shang Feng, may I ask if you have a record of your switchboard when you hang up the phone outside the public phone booth?" ”

"Yes, yes, but there is only a record of the time of the call and the call, and there is no way to record the content."

"Okay, you wait for me, I'll rush over right away." Lei Yunfeng put down the phone, rushed to the car with some excitement in his heart, jumped into the car and went straight to the Luojiawan telephone office.

Only from Director Liu, who received a call from Lei Yunfeng, he didn't know that this Lei Yunfeng, who was like a possessed devil, was going to find him in trouble, and he was terrified and restless, for fear that in the normal telephone business, he would be investigated and punished for some fatal mistakes.

It didn't take long for Lei Yunfeng to rush to the telephone bureau, rushed into Director Liu's office in three steps and two steps, and asked, "Can you still help me find the call record of the phone booth about 100 meters west of the telecommunications office, with the landline number 307?" ”

"Huh? Sir Shang, the 307 landline phone booth is located in a relatively busy area, and I don't know how many calls come in and out every day, and it is not easy to check the telephone records of these five or six days. ”

"Director Liu, do you feel embarrassed that I want to record all the calls made from the 307 landline between 4.25 and 7.55 a.m. five days ago?"

"Don't be embarrassed, don't be embarrassed, as long as you can provide a specific time for inquiry, I don't know if the chief wants to check it himself, or I will check it, or will the phone operator check it and send it to you and hand it over to you?"

"Don't bother others, you can find out the phone records for this time period and hand them over to me immediately according to the phone record requirements I want to query."

Lei Yunfeng arranged for Director Liu to go out, and every second counts according to what he said, and when Director Liu left, he stood up and grabbed the phone, and transferred Su Xiaoyan over in order to increase the time period when the manpower would be locked, which occurred in the call records of the 307 landline, for careful review.

It didn't take long for Director Liu to take the phone book according to Lei Yunfeng's request.

Soon Su Xiaoyan also rushed to the telephone bureau, and the two sat in Director Liu's office, carefully and carefully screening the phones that hung up from the 307 landline during the locked time.

After nearly half an hour of screening, it was found that on the page of a phone book registration, a registration for a call from a 307 landline phone was cut out.

And the time sequence of the calls made in the order of the upper and lower registrations was around 4.43 a.m. that day.

Could it be that there is some mystery in this hacked phone? Or did the caller accidentally tear this vital line?

Lei Yunfeng carefully examined the line of telephone records that had been cut out, and although it was not removed with a sharp weapon, there were obvious traces of human removal.

This discovery shocked Lei Yunfeng's heart, and he not only saw a ray of light for the detection of the case. He handed the record book that had been cut out of the phone calls to Su Xiaoyan, and asked in a low voice, "Can you see it?" Any thoughts? ”

Su Xiaoyan looked at it for a while and nodded, "Boss, this is someone deliberately cutting out this line, which shows that this call is very mysterious, and it shouldn't be done by the insiders of the Telephone Bureau, but how could outsiders sneak in and find out and remove it so easily?" ”

"There are two possibilities, one is to collude with inside and outside to commit the crime, and the other is that the perpetrator is very familiar with the telephone bureau, and may have infiltrated the crime, or he may be very familiar with a certain telephone operator, and take advantage of the opportunity to skillfully evade supervision and quickly commit the crime."

Su Xiaoyan frowned and looked repeatedly, but she couldn't find any useful clues.

"Ah Yan, you can now find out all the registrations from the 307 landline phone during the period from 4.25 to 7.55 when the message was leaked that day, and carefully and carefully transcribe it."

"Boss, I'm afraid I won't be able to copy all this for a while, why don't we take this phone register back and screen it according to the phone call time locked on it?"

"No, if we take the phone book away, it is very likely that our purpose will be revealed, once the sleeper agent finds out and takes other more secretive ways to sneak down, we will be more passive, copy it, I'll wait for you."

Lei Yunfeng walked out of Director Liu's office as he spoke, found Director Liu and asked some questions that sounded unbounded, but this was Lei Yunfeng's desire to find out from this messy questioning whether the operator of the telephone bureau had close contacts with people familiar to the outside world.

With Lei Yunfeng's questioning, Director Liu didn't dare to prevaricate, nor did he dare to be perfunctory, and he said everything he could clearly when he asked questions.

In the end, he didn't find any useful clues from Director Liu's conversation, Lei Yunfeng not only said to Director Liu: "Are you all on duty at the switchboard today?" Is there any compensatory leave? ”

"Only Miss Shen is on leave, now that she is dead, the others are here, if Chief Shang needs my service, please give me orders, I will definitely do it."

Lei Yunfeng suddenly said in a fierce tone, "I want to review your telephone operator. ”

Today, there are four telephone operators in the telephone bureau working at the same time, that is to say, there are five in total, and it happens that Miss Shen is on duty today, and all four of them are on duty at this time.

Lei Yunfeng walked into the switchboard room of the telephone bureau, and the four young and beautiful switchboard ladies saw that Director Liu brought in a suave young man, and asked jokingly while not only busy:

"Director Liu, I don't know what the origin of this young man is, is he the one who introduced us? Hehehe, we are all optimistic about this young man, so introduce it to us. ”

Director Liu listened to the nonsense of the four wiring ladies who didn't know how to live or die, and he was so frightened that he scolded with a tiger face: "Work time is so frivolous, be careful that I smash your jobs." I tell you, this master has something to do with you, and I hope you will cooperate well. ”

"Don't worry, Director Liu, we will definitely cooperate, do you want to talk about it one by one? Then I'll come first, hehehe. A handsome girl smiled at Lei Yunfeng and said teasingly.

"Very well, since this young lady is so open-minded, let's start with you." Lei Yunfeng pointed at the young lady with a smile and waved his hand in a chic manner.

This young lady surnamed Feng was the first to be clicked by the young and handsome young man, not only was she excited and said to the sisters around her: "Sister, if you help me answer the phone calls in and out, I will take the first step, hehehe." ”

After a short time, the girl surnamed Feng was interviewed and returned alone, without the peach blossoms on her face that she had just left, and with a frightened face, she sat in her position without saying a word.
