Under the organization of Ling Hai, all the staff involved in the investigation of the case held a case meeting together.

Even Jiang Liu was connected by phone.

Gen was the first to introduce some of the current situation of the deceased, as well as the state of the body.

Wu Dao followed up and shared with everyone the current direction of investigation and the clues he had mastered.

Ling Hai asked, "At present, it is determined that there are four people who are motivated, so what are the conditions they still need to meet?" ”

"There are three known conditions: access to wires, access to tight spaces under the roof, and access to the storage key." Wu Dao replied.

"Isn't that just a match between those four people and these ripe conditions to draw conclusions?" Ling Hai said.

Zou Lianya didn't agree with him, "This is not simply a match, there are some other external factors that need to be taken into account, such as even if they do not have the conditions to commit the crime, it cannot be ruled out that there are accomplices, and the case can be completed with assistance." ”

"It's important." Wu Dao agreed with Zou Lianya's statement, "After all, Zhang Lei's figure is taller than ordinary people, and it is too difficult for a person to completely complete the link from killing to splitting the corpse to throwing the corpse, and it is difficult to do it completely without revealing his feet." ”

"I have a question." Jiang Liu's voice suddenly came from the other end of the phone.

Ling Hai pushed the phone to the middle of the table, "Lao Jiang, say it!" We're all listening. ”

Jiang Liu proposed to go to the sanitation department to check the situation, since the garbage was to be collected there, so was there any eyewitness to Zhang Lei's body disguised as garbage when it was transported from the back door to the sanitation department?

Wu Dao responded to him, "We have investigated together before the sanitation department, and they said that they received a lot of garbage on the day the monitor was broken, but they will only crash the garbage away and destroy it centrally, and will not disassemble it one by one to check, so they don't know if there are human stumps." ”

"I suggest two directions, starting from the typesetting records of the cleaning department on the day, and starting from the garbage terminal docked by the sanitation department."

Jiang Liu's words are concise and to the point.

"Okay Lao Jiang, I'll check it when I go back." Wu Dao replied.

Ling Hai suggested that in addition to these two aspects, the potential connection between the two deceased people also needs to be investigated.

This coincides with what Jiang Liu said to Wu Dao before.

Soon, after reorganizing the key points of the case, everyone actively participated in the responsible link.

In the evening, Wu Dao received a phone call.

It was the dormitory boss who called, and the fourth Qi Bin finally regained consciousness after so many days, if he is free, I hope he can come and take a look.

Wu Dao and Gen said about it, and Gen said that he was very interested and wanted to go along.

After all, human blood was detected on his clothes before, if this is a criminal case, then Wu Dao is considered a related person, and it is better to have an unrelated person present.

The Fourth People's Hospital in Z City is a psychiatric hospital, which is often said to be a place for the mentally ill to recuperate, but it does not mean that it only admits schizophrenic patients, such as mental illness, severe sleepwalking, hysteria, and autism are all within the scope of their treatment.

Qi Bin was diagnosed with sleepwalking because he was talking to himself and was also sleepwalking, so he was sent here for treatment.

During this period, his family has always been around to take care of him, and it was not until today that he took the initiative to speak, and his parents hurriedly notified the dormitory boss to reassure them.

Wu Dao first greeted Qi Bin's parents, and then asked them to avoid it for the time being.

Qi Bin lost a lot of weight, his face was gray and a little tired.

"Wait for the money, what's wrong with me? I can't remember a lot of things. Qi Bin grabbed Wu Dao's hand, eager to know what happened.

Wu Dao roughly told him some information, and he gradually calmed down.

"I got a girlfriend, you know?" Qi Bin looked at Wu Dao.

Wu Dao peeled an orange for him, "Don't stimulate me!" Let's talk about the order of the dormitory, why shouldn't it be you, the fourth oldest, to get off the list first! What are you in a hurry! ”

Qi Bin took the orange he handed over and ate it, "I met a female student from the journalism department of the Communication University next door. ”

"Not a member of society?" Wu Dao knew that the news of the dormitory boss and second child had never been reliable.

Qi Bin sat up, "Of course not, I'm a tender grass, tender grass with flowers, and I can still let the old cow eat me, a yellow flower guy?" ”

Qi Bin said that he was in a very low mood some time ago, mainly because the girl's attitude towards him was hot and cold, and their relationship has only recently reached a new level.

Wu Dao couldn't help but remember that at the moment of the serial murder case against women, he would see everyone in the dormitory once, and the fourth child was really suffering from gains and losses at that time, and he didn't even bother to say a few words.

According to Qi Bin, he was on the verge of falling out of love at that time, and felt that his whole life was meaningless.

"Fourth, let me ask you, do you remember where the blood on your body came from?" Wu Dao suddenly became serious.

Qi Bin stuffed a clove of orange into his mouth, "Blood? What blood? ”

Wu Dao glanced at the root number that had been silent, "It seems that he forgot what happened at that time." ”

Gen rummaged in his bag for a while, and took out a few photos for Qi Bin, "This is the clothes you were wearing that day, there were a lot of blood stains on it, but you yourself were not injured, so this blood should be someone else's, do you recall anything?" ”

When Qi Bin saw the photo, he immediately panicked, and his whole body shrank into a ball, as if he remembered something, but he refused to continue communicating and kept hiding himself in the quilt.

Seeing this situation, Genhao suggested finding a psychological counselor to analyze the memories that Qi Bin did not want to recall through hypnosis.

This approach has played a crucial role in the detection of many cases.

Especially in recent years, with everyone's attention to criminal psychology, this science and the profile of psychological counselors have become particularly valuable, and many criminals are good at concealing or having complex personalities, which are invisible in the eyes of psychological counselors.

About two hours later, the psychological counseling analyst came to a conclusion.

Qi Bin should have encountered an accident while sleepwalking, he mentioned some words such as hotel, girl, high-rise building, dead and alive, etc., and analysts speculated that he should have witnessed a death and was very close to the deceased......

As for the blood stains, they may have been splattered on him.

"So what's going to happen to him next?" Wu Dao was very worried about Qi Bin's health.

"This requires concentrated psychological intervention and counseling, although he is usually an optimistic person, but the more people with this kind of trait, the more likely they are to fall into an extremely low mood when they encounter some ups and downs and difficulties." The counselor said.
