After a while, Zhou Ming hurried to the hospital, and the suspect had already been taken back to custody by his colleagues on duty, so Chen Zimeng was also waiting downstairs early. Without waiting for Chen Zimeng to enter the car, Zhou Ming hurriedly asked, "What did you find?" ”

"I found the doctor in the hospital and gave Su Qin a blood test, and in the morning Su Qin's test report came out, Su Qin had psychotropic drug residues in her blood," Chen Zimeng said, "That proves that her mother is right, Su Qin should have a mental illness." Zhou Ming thought for a while and returned, "Master is good, but there is another point, the current concentration of psychotropic drugs in Su Qin's blood is still at a high level, which proves that she has been taking a lot of drugs recently." "Recently, I have taken a large amount of it, is it because my mental state has become more disordered after the killing? Did she say why she increased the dosage of the drug?" This result was indeed a bit unexpected by Zhou Ming, "The blame is that she has no impression of this at all." "What, I don't have an impression, have all of his two personalities appeared in conversation with you?" "Yes, neither, and none of them should be lies." Hearing this, Zhou Ming's pupils shook slightly, and this conclusion was obviously beyond his imagination.

"Go on, what else to discover? You're not saying that the killer might be someone else. Zhou Ming asked, "Yes, master" Chen Zimeng sorted out his thoughts and said, "In the process of communicating with the suspect again, her two personalities still often alternate, but I probably found a pattern, that scared personality should be her real character, and that cold image may be the role she fantasized about when she was insane, maybe it is a desire in her heart to be strong." After listening to this, Zhou Ming nodded, which was basically the same as what he imagined.

"So assuming my conception is correct, then the normal personality that appears every day is the cowardly Su Qin, if she is a murderer, it should be her indifferent personality, and when she communicates with the cowardly Su Qin, she is very afraid of her stepfather, maybe because of her father's death, she will maintain a certain sense of distance from men, but when she talks about her stepfather, her fear has obviously deepened a lot, but when asked the reason, he is afraid and does not speak. So when her indifferent personality appeared, I continued to ask her the same question, and at this time, her expression appeared with extreme disgust, and she said that the two scumbags were all the way, so I deduced that ......" Chen Zimeng looked at Zhou Ming halfway through speaking, "So you think her stepfather also has bad thoughts about her?" Zhou Ming replied, "Master, I know that Su Qin's words are not all credible, but her stepfather I think it is very necessary to investigate, and Xue Cheng is also a well-known psychologist in the city, and Su Qin's body has a large number of residual psychotropic drugs, I think it is very likely to have something to do with him." ”

After listening to the apprentice's statement, Zhou Ming also fell into deep thought, although Su Qin kept saying that she was the one who killed, but there were still many doubts, at this time, Chen Zimeng investigated these cases again, then Xue Cheng seemed to be somewhat involved in this case, "Xiao Zhao, you and Liu Ying talk about it, after the investigation of Xue Cheng, come back and report the investigation to me, and send some people to secretly observe Xue Cheng's whereabouts, remember not to be discovered." Zhou Ming arranged, "In addition, Zi Meng, you and I will go back to the bureau to meet this Su Qin and see if she has any new words this time." ”

Back in the bureau, the two went straight to the interrogation room, and Zhou Ming said straight to the point, "Your medicine is prescribed by your stepfather." Su Qin obviously didn't expect Zhou Ming to be so direct, he was in a trance for a moment, and regained his composure after a while, "Yes." "Do you know the efficacy of the medicine you take?" "I don't know", "I don't know, then you dare to eat." "He is the most authoritative psychiatrist in the whole map, what do I eat if he prescribes me if I don't eat it?" The instantaneous quick answer also caught Chen Zimeng a little off guard, and watched the master continue to ask questions.

"So have you taken any medicine normally in the past few days?" Zhou Ming then asked, "I don't remember, let's eat it, after all, it's all become a habit." "How much did you eat?" "One every morning and one every evening, for so many years." Seeing that Su Qin's answer was flawless, Zhou Ming decided to suddenly change direction and asked, "Has Xue Cheng ever violated you?" This question obviously hit Su Qin's weakness, and in an instant Su Qin became at a loss, and began to tremble in fear again, "He is a scumbag, every time he looks at me like a beast, I am afraid of being alone with him, I told my mother that she is afraid of affecting her and doesn't care about me, I am so helpless in this family, especially when he knows that Pan Shenyuan is pretending to be my boyfriend, I look at Pan Shenyuan's eyes are so terrifying, as if he wants to kill him, no, as if he wants to kill me together." While saying Su Qin, he sobbed, Chen Zimeng and Zhou Ming looked at each other, as if they had another assumption in their hearts.

After the interrogation, the two returned to the office, Chen Zimeng said, "Master, if Su Qin said that he was a real person who committed the crime, would it be possible that it was Xue Cheng, who had an inexplicable hatred because of his deformed love, so he set up a bureau to kill the deceased, and in order to keep himself from being implicated, he used drugs to cause Su Qin to go insane, confusing the murderer with the one she thought of him, and then used this means to force Su Qin to turn himself in because he couldn't stand the inner torment, so as to achieve the punishment that he mentally thought that Su Qin betrayed him." ”

After listening to the apprentice's deduction, Zhou Ming lit a cigarette and fell into deep thought, "Wait for Zhao Ying to come back and take a look together, and in addition, you send someone to find the monitoring around Xue Cheng's house in the past few days to see the time when he and Su Qin are in and out." "It's the master," Chen Zimeng walked out of the office after saying that, and Zhou Ming silently walked to the window and muttered, "Is it really Xue Cheng?" ”
