Homicide Puzzle Code

"Hi, hello, this is Aneng Maintenance, what can I do for you?"

The soft and sweet voice on the other end of the phone did not relieve the criminal investigators at all. Du Zheng clamped the mobile phone by his neck, holding a notebook and a pen in his hand, and asked, "Hello, I am the chief of the Criminal Investigation Detachment of Jianglong City. Du Zheng, the criminal policeman of the second team of the case, now there is a murder case, and your company needs to provide some clues, is it convenient?"

The customer service opposite suddenly fell silent, and after a while said timidly: "You can ask, I... will try my best to cooperate with you."

Du Zheng thought for a while, and felt that it was necessary to let the other party relax, so he said, "Little sister, don't be nervous. We are here to find you to investigate clues. If your company has no problems, our police will not make things difficult for you."

"Okay..." The customer service responded, and turned to look at the supervisor who had been standing behind him.

Seeing the supervisor nodding, the customer service was relieved to continue the conversation.

Du Zheng: "Have you received a maintenance appointment for 5, Building 30, Chaoyang Community, a week ago, that is, May 6?"

"Wait a minute, let me check."

There was a quick keyboard sound on the other end of the phone, and then the customer service replied: "Hello, at 5:30 noon on May 12, a lady named Tan Jing made an appointment for our company's air conditioner external unit maintenance, and the address is what you said place."

Du Zheng listened and memorized, and then asked: "We probably understand this. Did they cancel the appointment later? Who canceled it?"

"The cancellation record on our side is at 6 am on June 3. The person who canceled the appointment was a man who said he was Ms. Tan's husband."

The customer service said, hesitated, turned to look at the supervisor who was walking away, and continued in a low voice, "Officer, I actually remember this incident. I originally wanted to call Ms. Tan again to confirm, but the person who called at that time There was a lady next to her, she said she was Ms Tan, and she confirmed that she didn’t need to come again, so I canceled the appointment.”

"How are you sure she is Ms. Tan?" Du Zheng asked.

The customer service said in embarrassment: "Officer, we are a small company, so the reputation of customers is very important to us, and generally nothing will happen, so we will try our best to agree to the requests made by customers."

Du Zheng felt a little helpless. No matter how beautiful their ideal life was, they were all living in reality. There were too many uncontrollable factors, and the police couldn't keep an eye on everyone and follow their standards.

He asked: "Does your company keep call recordings?"

"Yes." The customer service replied immediately. Although their company is small, there are quite a lot of rules. They have to conduct assessments on their customer service every once in a while, and the recordings of previous calls are their assessment content.

Du Zheng was almost giving up hope at first, but he breathed a sigh of relief and said to the customer service: "Then can you please call out these two call recordings and send them to me later?"

"Okay!" The customer service immediately agreed. It is not difficult for their customer service to call up the call records.

Although she is only a small customer service, she feels it is a great honor to help the police solve the case.

The customer service put down the phone and found that the supervisor walked behind him at some point, so he immediately stood up and lowered his head, not daring to speak.

The supervisor stared at her coldly for a long time, then suddenly said: "Why are you standing there, don't the police want to record the call, call it out quickly!"

"Ah?" The customer service was a little surprised, and then his expression turned to joy, and he sat back at his desk and started working.

As she turned, the supervisor smiled and nodded in relief.In this general environment, she can't control the company's arrangements and plans, but as long as she can change it personally, why not do it?

At the corner not far away, a worker saw everything in the office, and the viciousness in his eyes flashed past.Then he came out with tools, greeted the supervisor, and said, "I've completed the sewer in your company!"

The supervisor went to the toilet to check it, and nodded with satisfaction, "Go to the finance department to settle the bill, and leave a business card later, and I will call you again when there is a blockage."

"That's it!" The worker laughed loudly, which made other people in the office unhappy and caused a few complaints.

The worker immediately lowered his voice and stopped disturbing.He got the wages from the financial department, looked at the customer service who was still adjusting the records, his eyes were meaningful, he smiled silently, and left the office with the tools.

Hanging up the phone, Du Zheng closed the notebook and went upstairs from the corner of the stairs. Seeing the captain standing at the door, he stepped forward and said, "Captain, I checked with the maintenance company. They didn't send anyone over. The person who canceled the appointment is a Male, the customer service will send you the call records later."

"Okay, thank you for your hard work." Yu Jing nodded, but his eyes were fixed on the room.

Following the captain's line of sight, Du Zheng saw that Fang Zhishu had already tied the safety rope, and with Zhou Xiaoyang's help, he jumped from the window to check the air conditioner on the outer wall.

Lu Yan looked up at Fang Zhishu, pointed to the master bedroom and said, "Start with the master bedroom. Since the murderer is after the child, the master bedroom is his priority."

Fang Zhishu nodded, checked the ropes on his body, and said hello to Zhou Xiaoyang. In order not to destroy the evidence, he stepped out of the window sill carefully wearing shoe covers, stepped on the depression in the outer wall, and moved towards the air conditioner unit little by little. move away.

Climbing at high altitude is inherently dangerous, and Fang Zhishu is wearing shoe covers on his feet, making it even more difficult.Although Zhou Xiaoyang said several times that he could go out to check the physical evidence and Fang Zhishu could guide him indoors, Fang Zhishu still insisted on doing the investigation by himself.

He is indeed lazy, and occasionally fishes, but he clearly distinguishes between priorities, but this is his job, and it is also his responsibility as a trace inspection worker. When it is time to be serious, he will never relax.

Even though it is only early summer, the outdoor temperature has reached 36 degrees, and the salty sweat slid down from the forehead, as if on purpose, drilling into the eyes.Fang Zhishu suddenly felt that his eyes were very sore and it was difficult to open them. He closed his eyes tightly, tried to squeeze the sweat out of his eye sockets, regained his composure, and continued to climb towards the goal.

But the location of the air conditioner's external unit was farther than he imagined, and he had to pass a corner to see it.Fang Zhishu hung on the wall, thinking about how he would go around the corner.

The maintenance worker who was cleaning the neighbor's air conditioner saw the police coming out, and with puzzled expression on his face, he pointed to the corner ahead and shouted loudly: "Officer, you can go around from the water pipe, be careful!"

Fang Zhishu followed the worker's guidance and saw that there was indeed a place to stay on both sides of the water pipe.He clenched his back molars and approached, but saw half a footprint could be vaguely seen on the edge of the corner.

"This is……"

Fang Zhishu was a little puzzled, and tried to look downstairs.But he was on the 14th floor of a high-rise building. Once he fell, the consequences would be disastrous. He took a deep breath, grasped the decoration of the outer wall with both hands, and sat back slightly.

He knew very well that his legs were trembling, the strength in his hands seemed to be slowly withdrawn, and everything around him slowed down a lot, obviously it was only a few minutes, but he always felt that several days had passed.

He held his breath and cautiously turned his head to look down, for fear that if he relaxed a little, he would drop his hand and fall.

"There seems to be footprints next to the water pipe!" Fang Zhishu squinted his eyes, trying to make himself see more clearly, only to see vaguely footprints on the outer wall from all the way down.

But at the height of the 14th floor, let alone climbing, he was terrified standing up, how could someone climb up from the bottom?

Fang Zhishu thought, looking up along the footprints, the footprints did stop on the 14th floor, and there were some scratches on the air-conditioning external unit platform just one step away from him.

He grabbed the railing of the small platform and stepped over it in one step. The ground was firmly stepped, and only then did he feel a little safe.

Fang Zhishu turned on the camera hanging around his neck, took pictures of the details of the platform of the external machine, and shouted to the others in the master bedroom: "I found something!"

After taking all the photos, when he returned to the master bedroom and stepped on the ground, his feet were so weak that he almost knelt down.

Lu Yan stretched out his hand to grab Fang Zhishu's hand, and locked his eyes on the window in front of him.

"Thank you!" Fang Zhishu grabbed Lu Yan's hand and tried to stand up with difficulty, but before he could stand still, Lu Yan suddenly took a step forward.

Fang Zhishu, who had no support, almost fell face-to-face, grabbed things with both hands, looked up and saw that it was Yu Tui who had just come over, he was relieved, and thanked: "Thank you Yu Tui, Yu Tui is better... ..."

Before he could finish speaking, Yu Jing picked up Fang Zhishu's collar and pulled it aside, "Thanks for your hard work, take a rest first, and report to me later."

After his words fell, he had already walked to Lu Yan's side.

Fang Zhishu sneered helplessly, casually hooked a policeman's neck and slowly said, "No...they were still arguing in the morning?"

The policeman stood with difficulty, Fang Zhishu leaned close to him, his body weight was on him, but he responded immediately: "Forensic Lu just made a new discovery, the handle of the window seems to be loose."

"Really? Then I have to go and see." Fang Zhishu immediately became interested when he heard it, and he also came forward to watch.

He suddenly stopped, turned his head to look at the police officer just now, and asked, "What's your name, I haven't seen you before."

He is different from Lu Yan and Lin Xiangli. He has always worked in the forensic center, but this time he was transferred to the serious crime team to help with them, so he has met most of the people in the police station.But the young comrade in front of him was indeed unfamiliar.

Hearing this, Chu Li bowed seriously and replied: "Hi, Senior Fang, my name is Chu Li, I just graduated from the police academy, and I am a new police officer in the serious crime team!"

Fang Zhishu nodded, "Chu Li, okay, I will remember."

After he said that, he turned and walked to the window.

Wearing gloves, Lu Yan took tweezers, and carefully removed a strand of cotton thread from the bayonet of the handle, "It's new."

Fang Zhishu took out the evidence bag and took the cotton thread, carefully observed, "Judging from the traces of the break, it was torn off. Looking at the degree of pollution on the surface of the cotton thread, there is a high probability that it is new. I will take it back for a test, and then Give you the result."

Yu Jing continued to look at the window. The screw of the handle had been loosened, so the handle could be lifted easily, but the screw was not rusted, and the screw was not worn out, more like it was unscrewed deliberately.

Then he beckoned behind him, "Xiao Chu, take a picture of the details of the window. Go back to the team and find Meng Jingyi, and see if you can't simulate opening the window with cotton thread from the outside."

"Yes!" Chu Li obediently stepped forward to take pictures, and Fang Zhishu kindly taught him how to take pictures of physical evidence at the scene.

Chu Li listened carefully and immediately mastered the technique.

"Young man, work hard, you have a bright future!" Fang Zhishu patted Chu Li on the shoulder, and immediately caught up with Yu Jing.

Chu Li was full of fighting spirit, "Yes!"

Fang Zhishu turned on the camera and handed it to Yu Jing, "I found footprints on both sides of the water pipes on the outer wall. There is no Spiderman in this world. It is not possible for ordinary people to climb to the 14th floor purely by hands and feet. So I went to the external platform Looked up, there were obvious scratches on the railing."

Yu Jing zoomed in on the photo and focused his eyes. Such circular scratches were more like left by a rope.

He boldly hypothesized: "So someone tied a rope to the railing, and with the help of the rope and the hose, climbed all the way up to the 14th floor and jumped into the deceased's house through the window?"

Fang Zhishu nodded, "So I prefer that the deceased came to the scene for the first time to make arrangements, and then returned to the scene on the night of the crime to commit crimes."

Lu Yan listened from the side, and said at the right time: "So this air conditioner maintenance worker of unknown origin is the biggest suspect. Since he came after the child, the child is probably still alive."

"Speed ​​up, we must find the child before the murderer commits the next crime!" Yu Jing clenched his fists and asked loudly, "How's the field job?"

Zhou Xiaoyang's voice came from outside the door, "Boss, they said they found a blood-stained mobile phone in the grass!"

The author has something to say:

small theater:

"Little Police Report"

Chu Li: Yu Dui, you... hello, I... my name is Chu Li, I just... just graduated... from the police academy, I... I...

Yu Jing (with a strange look on his face): I remember that in your physical examination report, there was no mention of stuttering.

Chu Li: I... I... nervous.

Yu Jing (laughs): What are you nervous about?Don't worry, I'm merciful.

Zhou Xiaoyang os passing by: cut!

Chu Li: Yu... Yu team, your cell phone is ringing.

(Yu Jing took out a button bar computer from his bag)

Chu Li (gossip): Yu Dui, do you still use such an old mobile phone?

Yu Jing: No, I use it to keep in touch with old friends.

Chu Li: Oh...that must be a very precious friend, after all, few people use this kind of mobile phone these days.

Yu Jing (smiling): It is very precious, but young man, you ask too much.
