The scene was blocked, and Tan Yao was not suspicious for the time being, but he still stipulated that he could not leave S City and was summoned at any time. The death of Tan Hall is not a trivial matter, and the bureau attaches great importance to it. A deputy leader was ordered to take Du Heng to a meeting. The leader's surname is Fu, his name is Fu Lin, he is a big smoker, he just sat down, the cigarette did not leave his hand, the whole room was a little smoky, Mai Dong got up and pushed open the window.

Fu Lin extinguished the cigarette with some embarrassment: "Let's talk about the current situation." ”

Zheng Qian began to narrate the situation learned by the trace inspection department: "There are two deceased people in total. The female deceased's name is Qin Qing, 45 years old, who teaches at S University, has relatively simple social relations, and has not had any recent disputes with others. We checked the communication records related to her mobile phone, and there is nothing abnormal recently. The male deceased, Tan Xing, 53 years old, is currently the director of the Provincial Public Security Department, and we have not yet fully understood his social relations because of the complexity involved, and the relevant communication situation is also being reported to the higher authorities because it involves confidentiality. In addition to the footprints of the deceased and the informant, three different sets of footprints and fingerprints were found in the house, two of which are now being identified through a database of fingerprints. The two men were arrested eight years ago for intentional homicide and were released fifteen days ago. One of them is called Wei Yong, and the other is called Wei Wen, and I have sent you all the specific information. ”

"Are these two from M City?" Du Heng asked.

"Yes, the case of the two was handled by Tan Hall back then, and it is not ruled out that they have a grudge, so they are waiting for an opportunity to retaliate after they are released from prison. Zheng Qian continued: "We found messy furnishings in the deceased's home, apparently rummaging through something, leaving a large number of fingerprints in a hurry. That's probably what you can find in the trace exam. ”

"From the top of the body, the female deceased died an hour earlier than the male deceased, the cause of death of the female deceased was mechanical asphyxiation, there were obvious strangulation marks on the neck, there were traces of trampling on the back, and there were rough cotton threads left on the clothes, and we compared the missing line segments to the same material as the cloth on the sofa. The piece of cloth on the sofa was missing, and the piece of fabric that disappeared was most likely the murder weapon. The blood alcohol concentration of the male deceased was 589.35mg/100ml and he was drunk, so it is very likely that the male deceased did not notice when the female deceased died. The cause of death of the male deceased was excessive blood loss, multiple electric shocks to the body before death, foam in the nasal cavity, the whole head may have been soaked in cold water and compressed, and there was no obvious swelling in the lungs. Based on the two different methods of committing the crime, the forensic doctor speculated that the perpetrator may not be the same person. Wang Yue said what he thought.

"Of course it's not the same person, they all say that there are at least three people's footprints at the scene. Zheng Qian added.

"No, I suspect they were killed by two different groups of killers. Wang Yue explained: "The female deceased was dressed neatly and drank coffee when she died, so it is very likely that she was entertaining guests, and I don't know what caused the dispute, and she killed people in a moment of passion." ”

"Who would go to someone's house at night?" Zheng Qian asked.

"Is it possible that he is either someone else, or his own family, but the two are not familiar with each other, so he is neatly dressed?" Mai Dong immediately thought of Tan Yao: "When I asked Tan Yao this morning, I found that his mental state was not quite right, it looked like ...... Knocked over the drug. ”

"What does that mean?" Ding Wen didn't understand, "We asked him at the bar if he came back in the morning." ”

But between eleven and twelve o'clock it happened to be the time when the bar business was at its most prosperous, and if he disappeared for a while and then went back, it would be easy to hide it. Mai Dong continued: "I checked their landline at home just now, and the last call was to Tan Yao, the call time was 1 minute and 38 seconds, and the time was 11:21 in the evening. ”

"Yang Lei, take a look at the surveillance at the door of the bar, and pay attention to about eleven twenty to eleven forty. Du Heng instructed Yang Lei to take out the surveillance, several people watched it together, the night was very dark, the surveillance in front of the bar was very dark, and it was not easy to see, and when he saw it for the third time, Mai Dong shouted: "Stop! ”

Yang Lei enlarged the portrait, and Mai Dong pointed: "Look at this." The man in the video was wearing a mask and showed a hand, and Mai Dong looked at Du Heng: "The tattoo on his hand is exactly the same as Tan Yao." ”

Tan Yao got into a car, and Du Heng hurriedly asked Yang Lei to take a look: "Is there a car like this near the door of Tan's house?" ”

"Yes, eleven fifty-two. "A dark figure inside the surveillance came through the backyard of the house. At about 12:11, a figure hurried out.

"Arraign Tan Yao. Du Heng said: "If we revisit the site again, there must be something we missed." ”

Soon Tan Yao was taken to the police station, and he was extremely impatient: "It's endless, I reported to the police, you don't arrest people and arrest me every day for interrogation, what do you mean?

Du Heng ignored him and sat down: "I remember the first time I saw you, when I was five years old, Mai Mai and I were playing in the sand under the tree, diagonally opposite your house, and you were sitting on the piano bench playing the piano. Mai Mai said that you are like the prince in the book, although I hate to admit it, but at that time you were. When I was young, I was really jealous of you, and the children in the whole community liked to play with you, but I only had Mai Mai as a playmate, and you easily snatched her when you appeared. You can play the piano, I don't have all five notes. I remember you said you wanted to be the best pianist......"

"Did you have people bring me here today just to catch up on the old days? If you really like to talk about it, find a place to sit down and talk for as long as you want. Tan Yao hung his head and said sullenly.

Du Heng ignored him, and continued: "What we envy the most is that you have a good mother. Mai Mai's mother and I are both teachers, and they can treat all the students as their own children, but they will forget their own children. Your mother is obviously different, she will make you delicious pastries, will accompany you to parent-child activities, and will take you to amusement parks...... We've never seen her get angry with you, it's really funny to say, every birthday wish Mai Mai and I wish for a mother like you......"

"Shut up, I don't want to hear it!" Tan Yao said, covering his ears in evasion.

"Then let's talk about the case. Du Heng took a deep breath and calmed himself down: "We checked the surveillance, you went home at eleven fifty-two, what are you going to do when you go back?"

"My own home, do I have to have something to do to go back?" Tan Yao began to defend.

Du Heng didn't talk to him about it, and directly handed him the call record: "You went home because Qin Qing called you." ”

"So what?" Tan Yao rubbed his head: "I answered the phone, and I am the murderer?"

"Qin Qing is not familiar with you, you don't even want to say a word to her at the dinner table, and you generally won't talk to her when she calls, unless she says she has something very important to say to you, or she holds your handle in her hand. Du Heng paused for a moment and raised his eyes to look at him: "Although you have just come back from abroad, you clearly know that it is illegal to take drugs in China...... And your father is special, once this incident comes out...... You are impatient, but you still choose to come back. Du Heng took out the things in his hand: "At eleven thirty-two you got in the car, and at eleven fifty-two you got off the car at the back door and entered the house." Du Heng handed him the surveillance photos.

"The two of you had a heated confrontation, and she obviously didn't mean to hide it from you. And I insulted you as much as I could...... You put up with it all. Until...... She mentions your mother......"

Tan Yao was in a mess all of a sudden, and he immediately remembered the woman: "Do you think I will help you hide it? I won't! I want everyone in the world to know that the director of the anti-drug department who is selfless and selfless in the iron mask is a poisonous ghost. Do you think your mother's death was really an accident, you are as stupid as your mother, stupid enough to believe such a man. How high is your mother, when she was in school, she pretended to look at me with pity every day, and gave me small favors and small favors...... I wanted to throw up when I thought about it, but what happened in the end, she died! I slept with the man she loved the most, and enjoyed everything she had, and she had nothing. Look at you...... At the beginning, your mother said that you were her proudest work, but look at you now, no one is a ghost...... Does that little girl named Wendy make you happy? I really want your mother to see her proudest son...... I'm going to be ruined easily!"

Tan Yao wanted to calm down, Du Heng was deceiving him, he had no evidence, he even burned the murder weapon, nothing was left, don't panic...... He took a deep breath: "These are just your conjectures, I just talked to her about some ordinary things. ”

Du Heng then took out the evidence: "We found this when we revisited the scene. It was a medical record card: "We found the medical records in Qin Qing's room, she has moderate depression, she went to a detective agency yesterday and got a report." That report was about your father. Du Heng handed him the report, it was a spliced report, it was too torn to pieces, and the handwriting was very blurry: "I can't see it clearly, right, I specially asked the detective agency to find another one." ”

Tan Yao took it with trembling hands and read it at a glance.

"Qin Qing has always wanted to have a child of her own, thought of countless ways, took a lot of medicine, and as she grew older, it even became an obsession. She has an extreme personality, and in the long run, she slowly becomes moderately depressed. When she saw the report yesterday, you can imagine how she felt at that time...... So she thought about dying, but she wasn't willing to die for nothing, so she installed a pinhole camera in the living room, and then called you back, stimulated you, and then pushed you down the river to kill her. ”

Du Heng finally took out a video, which was taken by Qin Qing about Tan Yao's murder.

Tan Yao looked at it, scratching his head, what else could he say.

"I'm sorry that the third time we met after the reunion would be in a place like this. I'm also sad that you used to be beyond my reach because of you, and I tried to be better. I don't know what you've been through to become what you are now, but I'm really disappointed that the hands that belonged to the pianist became murderous hands......"

Tan Yao couldn't hold back any longer, buried his head in his slender hands, and cried bitterly.
