The forensic wife is very nice to me

"Severe mental illness is actually the mental illness that ordinary people call mental illness, and it is also a narrow definition of mental illness." Qiu Lan looked at the information in her hand, "People with this kind of illness are not clear in their minds, and all their behaviors are also unclear. Uncontrollable."

"However, this medical record has been going on for so many years, and it was diagnosed before she married Zeng Qipeng, so how could Zeng Qipeng marry a woman with mental illness?" Qiu Lan frowned, with a question mark in her heart .

After listening to her analysis, Xu Chengyan nodded and echoed softly: "This is indeed a suspicious point. The suspect's family background seemed to be good before. He got married suddenly without holding a ceremony and just registered. It is indeed suspicious."

"Hmm." Qiu Lan stared at the document with a thoughtful look.

Suddenly, she remembered the document Xiao Cong sent just now, and her eyes flickered slightly, "Officer Xu, you came just in time. Xiao Cong and I were discussing the girl's bones just now, and found something suspicious."

Qiu Lan turned around, clicked on the file in the computer, and slid to the page of the appraisal result, "Look, Xiao Cong made a mold for the deceased's tooth socket before, and then took the twenty teeth found at the scene one by one. Matched and found that one should not belong to the deceased."

"Doesn't belong to the deceased?" Xu Chengyan frowned, the expression on his face was a bit stiff, and there was a trace of doubt on his brows, "If it didn't belong to the deceased, whose would it be?"

"I have asked Xiao Cong to take the tooth to the forensics department. After they finish the test, there should be a result, but I preliminarily judge that it is an adult's tooth. Zeng Qipeng's tooth is intact, so it should not be his." Qiu Lan pursed her lips, her eyes were heavy.

"Could it be?" Xu Chengyan stared at the content on the screen suspiciously, and said softly, "It's Zhang Yunmei's?"

"That's what I guessed too, because it was brought back together with the girl's bones." Qiu Lan took a deep breath and analyzed calmly with one hand on her chin, "Wait for the forensics department to extract the DNA from the teeth." You’ll know when you come out and compare.”

"However, if this tooth is really the biological mother of the deceased, then I guess she has been killed."

Standing aside, Xu Chengyan lowered his eyes, thinking carefully about all the information of the case in his mind, and his lips could not help but purse, "Now all the evidence points to Zhang Yunmei, but the only suspect who has come into contact with her is Zeng Qipeng."

"But there is no way to get information about Zeng Xiaoqi and Zhang Yunmei from him."

Qiu Lan bit her lip lightly, frowned slightly, and lowered her head in thought.

She remembered that when she was in college, she heard a special lecture given by a foreign psychologist about the problem of mental imbalance caused by strong stimulation.

According to the investigation of the case, Zeng Qipeng had no mental illness before, but somehow he suddenly became a mentally disturbed person.

And in that special lecture at that time, foreign experts mentioned that in the memory storage area of ​​the brain of a patient with such a mental illness, the specific segment that stimulated his nerves will always be remembered.

Afterwards, under a certain amount of the same stimulus, the patient will involuntarily repeat what he did and said at that time, because such behavior and thinking are like echoes in the valley, repeating the same words constantly, so it is regarded as a psychological phenomenon. called memory echo.

Perhaps this method can help the case.

"Officer Xu, I thought of a way, maybe I can learn something from Zeng Qipeng's mouth." Qiu Lan moved her lips, raised her eyes to look at the person in front of her, and spoke firmly.

Outside the custodial ward of the Central Hospital, Qiu Lan found a female nurse Zeng Qipeng had never seen before, put on the same type of clothes she found at his home, and bought a doll that was about the same length as Zeng Xiaoqi's skeleton.

But this puppet has an enlarged photo of Zeng Xiaoqi pasted on its face.

"Doctor Qiu, is this really okay?" Xu Chengyan frowned, looking at the things in front of him, he couldn't help but feel a little puzzled.

"I don't know if it will have a specific effect, but this method was mentioned by an expert I once heard. We can try it, and maybe we can find some clues?"

"And Dr. Li and I will be by the side. If something is wrong, we can stop immediately." Qiu Lan pursed her red lips, glanced at Li Yaxian next to her, and raised the corners of her lips.

"Yes." Li Yaxian responded with an elegant smile, and softly echoed: "Officer Xu, don't worry, this is the memory echo proposed by Professor Wen Deli, but I really didn't expect it to be used to solve the case before."

"Okay, let's try." Xu Chengyan nodded, signaling to the colleagues behind him to open the door of the detention ward.

The female nurse walked into the room holding the puppet with Zeng Xiaoqi's face on it.

According to the plan, she only needed to inadvertently put the doll into Zeng Qipeng's sight and let him see it.

Sure enough, as soon as the doll was placed on the bed, the man with dull eyes immediately noticed her, his pupils lit up, "Qiqi!"

There was surprise and astonishment in his voice, "This is my Kiki, my Kiki, why are you here?"

The doll on the bed was carried into his arms by Zeng Qipeng. He stroked the doll's face kindly, with a smile on his face and a soft voice, "Qiqi, don't be afraid, Dad is here, don't be afraid, I will protect you."

Seeing his appearance, Qiu Lan knew that her plan was half successful. She looked at the female nurse in the ward, took out the mobile phone in her bag, and pointed the receiver to her lips, "Go get the puppet Take it here, pretend to be angry and hit the child."

The female nurse in the room heard the voice from the bluetooth headset, immediately instructed, strode to the bedside, pulled out the puppet from Zeng Qipeng's hand, put it on the bed, pretended to be angry, and kept patting the puppet , "Disobedient, I will make you disobedient!"

"I'll kill you, kill you!"

"You, don't hit Qiqi, don't hit Qiqi!" Zeng Qipeng froze on the spot in horror, his hands hovering in the air, kicking his feet anxiously.

It could be seen that he wanted to go up to rescue Zeng Xiaoqi, but there was an inexplicable sense of fear in his eyes, as if he would be afraid of the woman who beat the child in front of him.

"I'll kill you, I'll kill you, I'll make you disobedient!" The female nurse continued to move while paying attention to the people next to her, "Kill you, you little bastard!"

"Don't hit me." Zeng Qipeng was so anxious that his body was trembling, he took a few small steps forward but didn't dare to stop him, his eyes were flustered, and he kept muttering, "Qiqi is still young, still young, you Don't hit her, don't hit her!"

He stood there in fear, his brows furrowed, and his heart ached, but he dared not go forward in fear, so he could only murmur beside him.

"Angry, throw the puppet away and throw it against the wall." Qiu Lan stared at the scene in the room and ordered in a low voice.

The female nurse heard the words in the earphones, picked up the puppet, threw it heavily on the wall, and yelled: "I told you to be disobedient, and I will kill you. Let me see if you dare not listen to me in the future!" .”
