Today is also missed!

Hu Qing froze and didn't dare to move, Su Yueming cast a sympathetic look at him, if he didn't die, he wouldn't die, and no one could stop him if he killed himself.

"Okay, stop making trouble." Tian He interrupted a few people, and he said while fiddling with the computer, "I checked the water and electricity records of the teaching building according to the message sent by Ding Yixin, but I couldn't find it for some time Record."

This news cheered everyone up. Whether it is pretending to be Han Meng or killing people, it will take time, and it is impossible for Sun Hai to be in two places at the same time.

If it's not at school, it's one step closer to them proving that the fake Han Meng is Sun Hai.

"Su Yueming, check along this line, focusing on where he went at other times after he left the community." Li Zimu said.

In the form that Su Yueming brought back, Han Meng appeared at long intervals, and sometimes only once in two or three days. It can be concluded that he must have other residences.

Otherwise, if he kept running back and forth like this, there would be too many flaws.

Su Yueming was ordered to go out bitterly. There were too few of them, so it was not easy to investigate.

They didn't have any definite evidence for this case, so naturally they couldn't ask the city bureau to transfer them for help.

"That's fine, I'll go to the hospital again." Seeing Su Yueming go out, Hu Qing quickly stood up and ran out.

Ren Qingli turned the scalpel in his hand, and kept looking at Hu Qing with faint eyes until he escaped from the department.

About an hour later, news came from Hu Qing that he found one of the students Tian He had found before in the hospital.

About half a month before the victim was killed, a student was admitted to the hospital with a bad cold.There is only a playground between the ward where he lives and the office where the victim lives, and it takes only 5 minutes to walk there. The most important thing is that everything on the opposite side can be easily seen from the ward here, which is a good place for observation.

When Hu Qing got the news, he immediately contacted Ding Yixin. Ding Yixin acted very quickly, and immediately asked that classmate about the previous matter.

The answer was true. The student claimed that he was not sick or hospitalized at all. Instead, he lost his ID card before the summer vacation. During the summer vacation, he went to make up for it and got a new one before school started.

After confirming the situation, Ding Yixin and Tian He got busy. If Sun Hai used this ID card to go back and forth between the two places, he would definitely leave more evidence.

As long as they can prove that the ID card was used by Pirates Sun, they can prove that Sun Hai was not at school when the incident happened based on the records.

And as long as they can prove that Sun Hai was at the hospital when the crime happened, they can find a way to prove the possibility of Sun Hai committing a crime.

Tian He got busy. He retrieved a large number of surveillance videos, from hospitals and stations, countless videos were divided into small frames and put on the screen.

The sky darkened quickly, and it was already past the off-duty time, but several people in the department were busy and no one made a sound.

The time for the criminal police team to submit the case for finalization is tomorrow, and their time is running out.

What broke the silence was Li Zimu's phone ringing. When the default ringing sounded in the glass house, the three of them were startled.

Li Zimu stopped what he was doing, took his mobile phone and went directly to the door and pressed the connect and hands-free buttons.

"Hello, Li Zimu?" Su Yueming's excited voice sounded over there.

"Well, I pressed speakerphone."

"I found it, I found Sun Hai's rented house near the hospital! Haha, this turtle can't escape now!" Su Yueming was obviously over excited.

"Address." Li Zimu reminded.

"This is diagonally opposite the back door of the hospital..."

After hanging up the phone, Li Zimu looked at Ren Qingli, and Ren Qingli had already taken off his protective clothing and changed his clothes, took his work box and was ready to go out.

"I'll go there." Ren Qingli said.

Li Zimu nodded, and he looked at Tian He who was stretching his neck.

Tian He received his gaze, stretched in pain, then shook his head helplessly, "He was obviously prepared, all the videos I could find didn't have a positive face, let alone a positive face, if it wasn't for the ticket inspector After checking the time, it is impossible to tell that it is Sun Hai."

Based on the watch that Su Yueming brought back earlier, Sun Hai should have rented a house in the community before reporting the case, and reported the case after impressing other people in the community. After reporting the case, he immediately set up a fake scene in the community.

Then he went back to school and arranged an alibi, then went back to the hospital to kill people, and finally returned to school.

The whole process took as long as one month. During this period, in order to maintain the illusion that he was in the school, he also traveled back and forth between the community and the school many times.

"It doesn't have to be a video." Li Zimu thought for a while and said.

"Huh?" Tian He was at a loss.

In such a chaotic place at the station, what else can be used as evidence?

ticket?But the ticket was bought with someone else's ID card. Even if they went to the station to identify the face, the traffic staff probably wouldn't remember it.

"No matter what form it is, as long as it can prove that he was there at that time." Li Zimu entered the glass room, leaving Tian He alone to mutter something.

Li Zimu sat in the glass house for an entire afternoon. During this afternoon, he checked all the physical evidence, and then re-appraised in his own way.

He also checked the cup. The cup was indeed from the victim's office. It was a disposable cup uniformly issued by the hospital, and the words Obstetrics and Gynecology were printed on it.

The cup was indeed from the Department of Obstetrics and Gynecology and it did have Han Meng's fingerprints, but it did not have the victim's fingerprints.

But this doesn't explain much in itself, at most it can only mean that the victim did not give this glass of water to Han Meng, and based on the relationship between Han Meng and the victim, it is very likely that Han Meng poured the water himself.

Li Zimu also checked the rest of the physical evidence, but apart from this, he found nothing new.

After returning to the glass house, Li Zimu picked up the fruit knife again.

Time passed by every minute and every second, and Li Zimu checked the knife over and over again. This is how the case is investigated. It is impossible to put all the evidence on the surface and list one, two, three, and often it takes a little A little patience to repeat the boring inspection.

It was about nine o'clock at night when Ren Qingli came back with his toolbox on his back.

As soon as he saw Ren Qingli, Tian He, who was sitting on the stool with a sore buttocks, hurriedly asked how the situation was.

"I've seen the place Su Yueming found. It's a small hotel with no surveillance video. The room was vacated the night before the incident, and several people stayed there after that." Ren Qingli dug things out from the toolbox .

Listening to Ren Qingli's words, the anticipation on Tian He's face gradually faded. The more crowded the place, the harder it is to preserve the evidence. Even Tian He understands this.

Ren Qingli took all the things he had sorted out into the glass house. While putting down the things, he looked at Li Zimu next to him, and was about to ask how he was doing. When he turned around, he found Li Zimu lying on the table, frowning. He looked at the fruit knife in his hand.

"what happened?"

Li Zimu stood up, looked around, and turned to Ren Qingli after finding nothing, "Is there a blade? It's a very thin one."

With Li Zimu's appearance, Ren Qingli knew at a glance that he must have discovered something, he quickly put down the things in his hands and went to the side to get a clean scalpel blade.

Li Zimu took the blade and was about to do it, but found it inconvenient to operate. Before he could move, Ren Qingli put on his gloves and stood aside, "What do you want me to do?"

"Help me up." Li Zimu handed the fruit knife to Ren Qingli and told him to hold it with the handle facing up.

Seeing that Ren Qingli had fixed the knife, Li Zimu took the scalpel and stuck it in the gap of the handle.

The handle of this cheap fruit knife is made of plastic, and the plastic handle is divided into two pieces, which fit together up and down.

After Li Zimu stuck the blade into the gap and used some strength, the handle of the knife was separated with a click, and two pieces of plastic fell on the table.

Li Zimu and Ren Qingli looked at each other, and they both saw excitement in each other's eyes.

There was blood in the gap between the knife handle that fell on the table, and it penetrated deeply. In addition, there was a lot of dust and dirt in the gap around the edge of the knife handle.

"Am I coming or you?" Ren Qingli looked at Li Zimu.

"I'll come." Li Zimu said.

Ren Qingli heard this, and immediately went to the side to get cotton swabs and other equipment.

On the other hand, Li Zimu quickly took the bloodstains and dusty samples that penetrated into the middle, and then processed them with the help of Ren Qingli, and finally put them into the instrument for DNA testing.

"Do you think it can be measured?" Ren Qingli couldn't help asking after seeing Li Zimu put something into the instrument.

Li Zimu shook his head, he was not sure either.

Judging from the traces of wear and tear, this knife should have been used for a while. If this knife was not Han Meng's but Sun Hai's, then Sun Hai must have touched this knife.

Although the gap in the handle of the knife is small, the sweat on the hands can seep in.

Saliva and sweat are secretions, and there are no cells in the secretions. No cells means no DNA.

DNA can be detected in saliva because saliva usually brings out a certain number of oral epithelial cells, but the palm of the hand is different from the oral cavity and may not be able to detect epithelial cells, and their chances are very small.

After being silent for a while, Li Zimu took the rare initiative to break the silence, "If this knife really belongs to Sun Hai, with his personality, he would definitely practice it countless times before killing someone, because a person like him cannot tolerate failure."

The more Sun Hai practiced and used the knife, the more likely there were epithelial cells in his sweat, and the more likely they were.

But this is beyond their control, and now they can only resign themselves to their fate. If God does not help them, they can only accept their fate.

The DNA test was not so fast, and the two of them lost all thoughts of doing other things for a while, and they both leaned quietly on the table and looked at the fast-running machine in front of them.

Li Zimu was staring at the machine in a daze when something suddenly appeared on his body.

"Raise your hand." Ren Qingli's deep and magnetic voice rang in his ears.

Li Zimu turned his head slightly, Ren Qingli stood beside him at some point, and he took out a new set of protective clothing and put it on him.

"It's dangerous for you to do this." Ren Qingli said softly.

Hazmat suits are partly to prevent contamination of the evidence, and partly to protect them, since the evidence that is brought in is not always clean and safe.

"No need." Li Zimu moved aside, Ren Qingli spoke in his ear, making his ears itchy.

"If you are not obedient, I will not let you in."

Li Zimu glanced at him and felt that Ren Qingli's threat was naive, he could easily guess all the passwords of Ren Qingli's glass house, mobile phone and even bank card.

But he obediently raised his hand and asked Ren Qingli to help him put it on, arguing with people is a very mentally exhausting thing, and he was tired.

"tired?"

Li Zimu's eyes were a little surprised.

"When this matter is over, I will treat you to dinner."

Hearing the word "eat", Li Zimu's stomach growled in unison, he was hungry.

Ren Qingli let out a chuckle, he looked at Li Zimu who was stroking his belly, and couldn't help but raise his hand to ruffle Li Zimu's already fluffy and soft hair.
