Su Duyun and Li Haoran walked into the office hall together, and as soon as they entered, they saw many colleagues standing at the door to greet them, and everyone applauded to welcome Captain Su back.

Su Duyun was very moved, she smiled, but wanted to cry even more.

Hurriedly said a few happy words to everyone, and walked back to his office.

She sat down in her seat, leaning back in her chair, a little hard, a little numb. She sat up straighter again, and saw that Li Haoran was still sitting on the sofa by the window, as before, under the sun, his face was full of light.

"Are you tired?" Li Haoran asked with concern when he saw that her face was not very good.

Su Duyun smiled, and a pair of small dimples reappeared, "I just arrived at the office, I haven't done anything, how can I be tired?"

Li Haoran grabbed his hair a little embarrassed, and said with a smile, "If you are tired, rest more, after all, you haven't been here for a long time, start with simple work, don't be reckless." ”

Su Duyun looked at him, looked at his office supplies on the table, everything started again, and the haze in his heart was blown away a lot, and said with a smile: "Okay, you go out, I'll sort out the original work first, and then take over the new job." ”

"Yes, Captain!" Li Haoran stood up respectfully, saluted, and walked out dignifiedly.

Su Duyun chuckled, turned on the computer, and checked his work records.

"Hey, what's going on? You guy, are you afraid that you won't be able to support your daughter-in-law? Zhang Sheng saw Li Haoran come out, and stepped forward to sarcastically say.

Li Haoran hammered him and said with a wry smile: "I'm afraid that I'll suffocate her at home, although we are looking forward to a holiday and rest all day long, but if you really take a long vacation, are you willing?"

Xiao Zhang covered the place where he was hammered, with a painful face, "I'm going to report a work injury, you always bully me like this." ”

Li Haoran stepped forward and rubbed it vigorously, and Xiao Zhang, who kneaded it, screamed twice before he stopped and said with a smile: "Do you think you are sick Xi Shi? You are still injured at work, you are really embarrassed to say it!"

Xiao Zhang hurriedly dodged to the side and acted like a little daughter-in-law, and the colleagues on the side laughed.

"Hurry up, take out all the materials of the chemical plant case, and let's go to the conference room to study and study together. Li Haoran said seriously.

Zhang Sheng also returned to his usual routine, picked up the materials and entered the conference room, because it was a collaborative investigation, so this time only the two of them followed up.

Zhang Sheng put the new material on the screen.

According to the degree of decay of the female corpse, she has been dead for at least ten years, and there are burn marks on the surface of the skin, which should be corroded by strong acids. The fatal wound is a rigid metal piece about 25 mm in diameter that is inserted directly into the chest cavity from the back until death.

There were no tools for committing the crime at the scene, because it was a chemical plant, so the strong acid was easy to obtain, but the crime work that caused fatal injuries had been tested at the scene and in the surrounding area, and there was no result.

Starting from the personnel information, the relevant missing persons cases were sorted out ten years ago, and there were several similar ones, but after investigation by the local police, they have all been ruled out.

And the boss of the factory couldn't get any information, he just said that he didn't know anything, and the factory was waiting to make a move, and this was another murder, and it definitely couldn't be sold.

And the owner of the factory has been abroad ten years ago and has no time to commit crimes.

"For such a long time, if we hadn't found it, it is estimated that this female corpse would have been completely forgotten by people along with this factory. Xiao Zhang put away the materials one by one and put them back in the file box.

"The key point now should be the tools for committing the crime and the information of the deceased, as long as you find these two, you can find a breakthrough. "Li Haoran has always loved to find key points when handling cases.

The two checked the detailed pictures of the scene according to the clues provided by the local police, and before they knew it, it was noon.

Su Duyun walked in with three boxed lunches.

"Hey, why is there still mine? I'm so sorry. Xiao Zhang stretched out his hand and took it, but there was no embarrassment on his face.

Su Duyun chuckled, handed Li Haoran a box, and sat down beside him.

"How is it, are you tired?" Li Haoran asked her.

Su Duyun shook his head, took a small bite, and then said: "I sorted out some original work records, and I was going to go out in the afternoon, and the Eastern District Police Station caught a thief." ”

Xiao Zhang saw that Su Duyun didn't move much, and saw that there were still a lot of braised pork in her box, so he stood up and stretched out his chopsticks to Su Duyun's lunch box, "What's so good about the thief, I have a big case here, do you want to hear about it?"

Li Haoran hurriedly blocked Xiao Zhang's chopsticks with his chopsticks, "How can you eat my daughter-in-law's dishes, who knows how much saliva you have on your chopsticks." ”

Xiao Zhang's eyes widened, and he said justifiably: "We used to eat like this before!"

Li Haoran's eyes widened, and he said hatefully: "That was before, not now." ”

Xiao Zhang sat back in his seat in frustration and muttered, "Stingy, I'm too lazy to pay attention to you." ”

Su Duyun chuckled, and after Xiao Zhang, he sandwiched a large piece of braised pork, and then sandwiched two pieces of braised pork for Li Haoran.

Xiao Zhang swallowed it in one gulp and grinned.

Li Haoran hurriedly clipped it back to her, and put another piece of meat to her mouth, "You have lost so much weight recently, you need to eat more meat." ”

Su Duyun smiled at him and ate the meat in his mouth.

"Oh my God, I can't stand it. Xiao Zhang on the other side covered his eyes and shouted.

"I can't stand it, get out, it's annoying to look at you. Li Haoran really wanted to hammer him again.

"You guy, you have a daughter-in-law and forgot your partner, if I hadn't worked hard to get this case, you wouldn't even have a chance to see it, and I'm so angry. Xiao opened his mouth and said, his hands could not stop, and he stuffed all the food into his mouth like a hungry ghost.

Li Haoran sat opposite, coaxing his daughter-in-law to eat, laughing, after coming here, everyone knew each other well, and they got along for two days, all of them were good friends.

"Is that the case of the female corpse of the chemical factory?" asked Su Duyun as she ate.

"Well, Team Zhang and I have been working on this case recently, and it wasn't originally under our control, but we found out anyway, so we fought for it and assisted in the investigation. Li Haoran replied.

Xiao Zhang quickly finished eating, packed up the lunch box, and didn't forget to stare at Su Duyun's braised pork that he hadn't finished eating.

Li Haoran hurriedly brought a book and threw it at him, "The meal is also finished, just go out for a walk, don't always be a light bulb here." ”

Xiao opened his mouth and pouted, "I want to report the case to the Su team, why do you always look at me unpleasantly." ”

"Eat! You think everyone is as hungry as you are. Li Haoran said indignantly.

Xiao Zhang laughed, "Pull it down, I used to stand in front of the corpse, and Team Su and I can also eat, unlike you, the little daughter-in-law!"

"Let's talk about the case, you two don't fight. Su Duyun stopped it in time.

Xiao Zhang wiped his mouth with a tissue, and then gave a brief introduction to the morning's situation.

"Well, Haoran is right, the tools for committing the crime and the information of the deceased are indeed the key to solving the case. You see, since everyone has been killed, why do you put it in an iron box? And put it in a chemical factory? Why don't you just find a place to bury it? Is it that the criminals have other purposes?" Su Duyun thought for a moment and said casually.

Xiao Zhang and Li Haoran looked at each other, yes, they hadn't thought about it before.

"I think there are two possibilities for the criminal to do these two things, it may be that he is very superstitious and needs to be left like this. It is also possible that this person is important to him, and he can't bury her in a hurry. Su Duyun finished eating a box of lunches, and it was still very fragrant.

"But these assumptions, you have to find out who she is first?" Xiao Zhang asked.

Su Duyun thought as she packed up her lunch box, "Maybe her family didn't know she was missing, or maybe his family knew about it but didn't report it." The former is more likely. ”

Su Duyun cleaned up, wiped the table, and continued: "You can check the people who have no bank records, no consumption records, and no traffic records from ten years ago to the present, now is not the era of big data, it is easy to find similar people." ”

Li Haoran sat on the side and looked at her who stood up, her eyes were still bright, and her small dimples were deep.

She's still her!
