"Team Lu, how should I interrogate?" Liang Fanxin asked Lu Yifan cautiously. After all, Lu Changfeng's identity is relatively special, and now he is only suspicious of him, there is no evidence, and there is no way to ask him at all.

"Just interrogate normally, don't worry about his relationship with me!" Lu Yifan said with a cold face, "If you can't ask, you can use Tian Xue to trick him." ”

"Good!" Lu Yifan's opinion was the same as what Liang Fanxin thought in his heart, and when he saw that Lu Yifan took the initiative to mention it, he hurriedly agreed.

Seeing that Liang Fanxin agreed so quickly, Lu Yifan couldn't help but glance at her. Liang Fanxin stretched out his tongue mischievously: "Your relationship is not very good, I don't want you to participate because I'm afraid you won't be able to hold your breath." Liang Fanxin explained curtly.

"Go ahead, I'll watch from the monitoring room." Lu Yifan encouraged Liang Fanxin.

So Liang Fanxin and the monkey walked into the interrogation room.

"Officer Liang, I don't know what you are looking for me to know? I don't know if I'm assisting in the investigation now, or if I'm the identity of the suspect? As soon as Liang Fanxin walked into the interrogation room, Lu Changfeng took the lead in questioning her, full of resentment. After all, it was brought in the name of assisting in the investigation, but it ended up being locked in the interrogation room for half an hour, and anyone would be angry.

"Mr. Lu, there are some clues that need to be sorted out, I've been waiting for a long time." Liang Fanxin said with a smile.

"I want to ask, does Teacher Lu have a lot of contact with Tian Xue?" Liang Fanxin asked Lu Changfeng, "I heard from the school teacher and Tian Xue's roommate, Tian Xue and you are very familiar?" ”

"Familiar? I guess it's not, I've only done psychological counseling for her two or three times, and I'm not particularly familiar with her. Lu Changfeng thought for a while and said.

"Really? Could it be that Mr. Gao and Tian Xue's roommate remembered wrongly? I wonder if you can let me see Tian Xue's medical records? Liang Fanxin then asked.

When he was at school, Lu Yifan specially asked Lu Changfeng to bring Tian Xue's medical records, just to see the connection between Lu Changfeng and Tian Xue from here.

Lu Changfeng helplessly handed over the medical record in his hand to Liang Fanxin: "Officer Liang, I am a psychological counselor, and the treatment of patients should actually be confidential, but I understand that these things are necessary in order for you to solve the case, but I hope you don't spread them!" ”

"Don't worry, the secrecy regulations of our police station force you to imagine more!" Liang Fanxin said impatiently, and then looked through the medical records.

Judging from Tian Xue's medical records, the contact between her and Lu Changfeng is indeed relatively small, only four times, which is similar to the two or three times that Lu Changfeng said.

And judging from the medical records, Tian Xue's psychological counseling treatment was extremely uncooperative, so Lu Changfeng also wrote some words such as 'uncooperative treatment, slight autism, psychological distortion' on the medical records.

"Teacher Lu, doesn't Tian Xue cooperate with the treatment?" Liang Fanxin looked at it and asked Lu Changfeng.

"She probably didn't want to ask me for counseling so much, she just wanted to find a place to hide. Every time she came to me, she sat alone and didn't speak, or spoke very little. I only learned from her words that she may have suffered more serious domestic violence, and of course, from her actions, I also noticed that she was hiding something. Lu Changfeng said recalled.

"She is like a little girl who has never experienced being cared for, and has always lived in her own spiritual world. Then every time you touch the real world, you suffer a blow. ”

"What do you mean, can you be specific?" Liang Fanxin was in a fog when Lu Yifan said it, and he didn't know what he was talking about.

"It's autism, psychological distortion!" Lu Changfeng raised his head and explained to Liang Fanxin, "No one cares about her, they care about her, so she has always lived in her own world, so she has never had friends!" ”

After Liang Fanxin heard it, she left and thought about what Huang Xiaoling said, she felt that she was not Tian Xue's friend, the two were just classmates who happened to be assigned to a dormitory, and Tian Xue basically had no communication with her.

"And this situation lasts for a long time, so her logical judgment is based on what she thinks, so she is psychologically distorted!" Lu Changfeng continued.

Speaking of psychological distortion, Liang Fanxin's mind resurfaced the strange smile on Tian Xue's face when he was in the interrogation room. Why would a sixteen-year-old girl face a corpse so calmly, calmly destroy and dispose of evidence, and then calmly call the police.

In the face of the psychological attack of the police, he was unmoved, and even played himself, is it all because of psychological distortion?

Liang Fanxin couldn't help but rub his brows with a headache, blaming himself for not learning criminal psychology analysis well when he was in the police academy, and now he can't even handle a little girl.

"Teacher Lu, I don't know where you are on the night of the 19th of this month?" Liang Fanxin calmed down for a moment, and suddenly asked Lu Changfeng.

"Nineteen?" Lu Changfeng was stunned for a moment when he heard this, then a trace of doubt appeared on his face, and then he tilted his head and thought for a while.

"The 19th is supposed to be a rest day, I don't seem to be at school, and I go to bed early after eating at night." Lu Changfeng recalled and explained to Liang Fanxin.

The nineteenth was the day Du Lei died, and Liang Fanxin asked about Lu Changfeng's whereabouts, naturally to investigate his possible crimes.

"I wonder if anyone can prove that you're home?" Liang Fanxin was not satisfied with his return, and said that he went to bed early, so who knows if he slept at home, and it is possible to run out and kill people.

"I'm sorry, I live at home alone, and there shouldn't be anyone who can prove that I'm at home." Lu Yifan said helplessly.

"What about the night of the twentieth? The evening of the 20th should be the day when the students return to school, you should have already gone to work, is there anyone who can prove that you went to work? Liang Fanxin then asked.

On the evening of the 20th, at around eight or nine o'clock, Liang Fanxin and Lu Yifan bumped into the murderer at Du Lei's house and came back to find the syringe bag they left behind. So if Lu Changfeng is really the murderer, it is impossible for him to appear in school.

"Eight or nine o'clock is the time for students to study in the evening, and I am in the office to sort out the medical records. If you need to prove it, you can go to the school and ask the teacher, and there should be a lot of people who see me going to and from work. Lu Changfeng said calmly.

Liang Fanxin glanced at the monkey and motioned for him to record all the information.

"Okay, Mr. Lu, I want to trouble you to stay here for a while, we need to sort out the clues, and there may be some things that you need to cooperate with the investigation." Liang Fanxin said embarrassedly, and then walked out with the monkey.

"How about Team Lu, do you see any suspicions?" Liang Fanxin walked out of the interrogation room and went straight to the monitoring room, found Lu Yifan who was watching the monitoring and asked him.

"No, I haven't been in contact for more than four years, and I don't know much about him." Lu Yifan looked at the surveillance screen and said.

"Regarding Tian Xue's medical records, I have read them, and they are all records of the normal time period. If it was really a night meeting, I suspect that he would not have recorded it at all, otherwise he would not have met secretly at night, and Tian Xue would not have been tight-lipped about his roommates. Liang Fanxin said his analysis.

"Go to his house and school, investigate his movements on the nineteenth and twentyth, and see if what he says is true!" Lu Yifan added, "At these two points in time, he said that he was alone. If he is really the murderer, then secretly going out or returning home, it is very likely that he will be seen or filmed by the surveillance, you go and check it. ”

"I've arranged for the monkeys to investigate."

Liang Fanxin looked at Lu Yifan frowning, and he could understand that he must be in a very uncomfortable mood now, after all, Lu Changfeng is his younger brother, if his younger brother is really a serial murderer, what kind of mood he will feel as his elder brother can be imagined.

"Why are you looking at me like that? Think I'm pathetic? Lu Yifan noticed Liang Fanxin's eyes, staring at her like an eagle.

"No ......" Liang Fanxin hurriedly waved her hand, she didn't dare to pity him.

"Humph!" Lu Yifan snorted lightly, turned his head and left.

Liang Fanxin looked at Lu Yifan's back, he was really a hard-mouthed and soft-hearted master, and when he just left, he finally saw Lu Changfeng, it seems that his mood is indeed very uncomfortable.

"Why don't you keep up!" Lu Yifan's voice came from the front, pulling Liang Fanxin's thoughts back.

Liang Fanxin trotted to keep up with Lu Yifan's pace and asked, "Team Lu, where are we going now?" ”

"To school, of course." Lu Yifan looked at Liang Fanxin with a very speechless look, as if to say, 'Why are you so stupid?' ’

Liang Fanxin suddenly exploded, and when he first went to school, he didn't understand the situation well and came back, and now he has to run again!

Lu Yifan suddenly stopped, Liang Fanxin couldn't hold back and bumped into his back at once, Lu Yifan smacked his mouth, looked at her with some disgust, and said, "Why are your eyes so big?" ”

Liang Fanxin felt that this scene was familiar, and suddenly thought of the first time she went to the police when she first came here, when both sides looked at each other unpleasantly, and now it is such a situation, thinking of this, Liang Fanxin laughed out loud all of a sudden.

Lu Yifan looked at her a little inexplicably, this person was still laughing after being scolded, isn't he a fool? "Normal!"

Hearing Lu Yifan's reprimand, Liang Fanxin immediately suppressed his smile, coughed lightly, and pretended to be serious, but the smile in his eyes did not decrease at all.

Lu Yifan glanced at her and walked forward again, with a smile on his lips that he couldn't hide, shaking his head lightly while laughing, after Liang Fanxin's trouble, his heavy mood seemed to be a little better.

The two got into the car, Liang Fanxin noticed that Lu Yifan was just holding a cigarette but not lighting it, thinking back to the past few days, it seems that he has never smoked, but just hung the cigarette to his mouth and pretended, she couldn't help but be a little curious, could this big smoker still change sex? "Team Lu, why don't you light your cigarettes?"

Lu Yifan took down the cigarette from his mouth and pinned it to his ear, and said casually: "If you want to quit smoking, wait until your lungs are completely black." ”
