"This murderer didn't just kill these people." Wen Mo took out the information on Ye Mingne's case and She Xinyue's case and spread it out: "This is a supplementary investigation by the police after it was found that the identities of the two deceased were confused, and the object of interrogation was the neighbors of Ye She's two deceased. ”

"The statements of all the neighbors of the two deceased have an interesting point: after the two deceased were actually dead, there were still people in the house who saw signs of their activity."

"You mean ......?" Luo Qin felt a little incredulous.

"The murderer didn't just kill the victims, she also lived quietly as them for a while, and when the time came, she would wait for the opportunity to change to another one, constantly changing her identity. With such a stack of ID cards, ten victims, the murderer no longer cares whether to kill or not, as long as she can give her a new identity and life, she never minds letting her hands be stained with blood, which can be seen from the fact that she dared to kill Li Hao in broad daylight. She was frightened and fled in a hurry, and she will definitely find a new victim in the shortest possible time, and go incognito again, Luo Qin, there is not much time left for us. ”

"As you said, start from the evidence, but although the evidence we have seems to be a lot, we can use very little, the murderer may commit another murder at any time, and we don't even know which city the crime will take place, and what's worse is that the murderer is used to hiding the body, we may not even know whether the murder really happened."

"The nature of a serial killer dictates that she will definitely do it again. No matter how tight our time is, we have to follow the evidence step by step. You have to remember that we are human beings, not gods, and it is impossible to conjure clues out of thin air to save everyone, even if the murderer commits murder again, we have not done anything wrong, and learning to be relieved and learn to face it is also a compulsory course for psychological experts. ”

"For a serial killer, the first killing is always the most special, let's pack our things, we have to go to Liu Yumei's hometown."

Q City, H Province.

After a four-hour train, Wen Mo, Luo Qin and Cheng Feng arrived in this city in northeastern China. In the early days of the founding of the People's Republic of China, the city that rose with oil also declined due to oil, rows of newly built new buildings, with scattered pedestrians on the street, made people feel a little lonely for no reason, and the three of them did not waste time, and went straight to the police station of Liu Yumei's aunt's house according to the address, explained the intention, and under the guidance of their peers, they went to the door.

Liu Yumei's aunt Sun Hongyan is a typical low-level citizen, and when she heard that the police came to the door, her face sank and she wanted to close the door. The film police who came with him obviously had already learned Sun Hongyan's trick during the last investigation, so they took the first step and held the door: "Sun Hongyan, we are just here to understand Liu Yumei's affairs, if you don't cooperate, we will take you back to the police station, and you choose the place yourself." ”

Sun Hongyan reluctantly opened the door: "Come in, come in, it's really a group of ghostly guys." ”

The group sat down, and Sun Hongyan's face was long: "That dead girl hasn't seen anyone dead or dead for 20 years, what kind of sin have I done, every day the police come to me to ask me about her situation, she is a twenty-year-old living person, where is I who I want to see if I can't see it?" ”

"Sister Sun, think about it well, before Liu Yumei disappeared, you didn't see any strangers around her?" If the murderer wants to replace the original Liu Yumei, he will definitely have contact with her for a period of time before the killing, and someone may not have seen the murderer.

"Alas, my mother, I am 63 years old this year, where is my head so good, and I remember the little things twenty years ago so clearly? Besides, that dead Ni is a mourning star of her father and mother, I can't hide yet, how can I rush to find her, how do I know what fox friends she has? ”

"Think about it again, after all, Liu Yumei has no relatives in Q City except for you, and you are the one who applied to the court for a declaration of death."

Sun Hongyan immediately jumped to her feet: "I can't remember, I can't remember, I can't remember how many times you ask, just Liu Yumei's little fox, she must have died outside, you catch the murderer elsewhere, don't hang around my house every day, there is such a niece, I am too cold to mention it!" ”

Sun Hongyan was very emotional, her voice became louder and louder, and she even stomped her feet and slapped the table, eager to sweep these obstructive policemen out immediately.

"Mom, what's going on?" Sun Hongyan made a lot of noise, and no one sitting heard the door open, so when he saw a middle-aged man who looked similar to Sun Hongyan entering the house, he was really startled.

Sun Hongyan's son Sun Baozhu obviously didn't expect that there were four people in police uniforms sitting at home, and they were on the spot for a while, but Sun Hongyan wiped his face, pulled his son aside and said a few words, Sun Baozhu's face was a little pale, and he glanced at them with a complicated expression, without saying a word, he turned around and went out again.

After driving her son out, Sun Hongyan gave an eviction order: "Let's go, I don't know anything, don't come back in the future." Let's go! ”

Coming out of Sun Hongyan's house, the film police explained a little embarrassedly: "That, our people are still very simple, it's rare to be like a shrew like her, don't be prejudiced." ”

Wen Mo smiled and didn't speak.

Back at their quarters, the three of them got together.

"This time in Q City, we came in vain, I really didn't know that there was such an aunt, I didn't care about my niece, I took the demolition money of my niece's house with a clear conscience, and the police came to understand the situation so uncooperatively, and I was not afraid of the money biting." Luo Qin was a little indignant, he has been a policeman for many years, and he has seen a lot of people of all kinds, and this kind of superb relative is still quite rare.

"Of course she's afraid." Wen Mo smiled and nodded Luo Qin: "Something is wrong with her son." ”

"Yes, otherwise why did the police come to the house to find out about his cousin, who has nothing to do with him, and he turned around and left? And when we leave, we will be scared when we look at it. Cheng Feng took out a cigarette, and just wanted to smoke it, but Wen Mo frowned when he saw Wen Mo staring at his hand, stuffed the cigarette back again, and drank a cup of water without a sip.

"Did you notice that the structure of their house was strange? The balcony will be dozens of centimeters higher than the living room, and no one will decorate it like that with such a thick cement platform. And the balcony was empty, not even a clothes pole, apparently unused. The only sunny balcony in their house is not used, which is strange. ”

Plus, Sun Hongyan's reaction. It stands to reason that her niece's whereabouts have been unknown for 20 years, and a police officer came to her door to ask her, and it was normal for her to be impatient, but why did she act angry? What is the force that supports her hatred of a junior she has never met a few times? ”
