Zhou Ning led people downstairs, and met Deputy Director Zhong on the way. Zhou Ning didn't take the initiative to say hello, but the man also turned his head, as if he didn't see it, and just missed it perfectly.

Going downstairs, Pharaoh had already parked his car in front of the door, holding a bucket, and when he saw someone coming out, he hurried up.

"Wash your hands. I went in just now. The smell in the bathroom is a bit spicy. I guess you can't wash your hands."

Da Zhao raised his finger towards Old Wang and said with emotion:

"Master Wang's observation ability, whoever dissatisfies you, I dissatisfy others. As expected of working in the technical department, he is more sensitive than ordinary police officers, and he also takes care of Zhou Xiaozhou's hobbies."

"Just talk too much, wash your hands and go back to rest."

Zhou Ning pushed him and was the first to stretch out his hands. Lao Wang poured out water and he washed it. He suddenly felt alive. After all, the hallway smelled like toilets. It looks like, needless to say about other aspects.

Several people got into the car, Da Zhao sat with Zhou Ning, and said in a low voice:

"Not to mention the lack of cooperation from the local area, I looked at the deputy director of the Xinghua City Bureau, Zhong, who didn't feel anything at all, and didn't seem to be afraid of our careful investigation. Do you have confidence in this case, or in the traces they cleared up? "

Zhou Ning did not refute, because since they arrived in Xinghua City, let alone cooperation, it can be said that they have obstructed everywhere, and after the on-site inspection, it is not difficult to see that the scene has been cleaned by professionals, and all traces have been deliberately erased.

Zhou Ning closed his eyes, thirsty, tired, hungry, all the uncomfortable feelings came up, and even the shaking of the car made him feel sick for a while.

Of course, today's experience also made him very disgusted. From the day he entered the Public Security Bureau, Liu Yongxin, Xu Dayuan, Sun Ju, Hu Ju, etc. he knew all worked hard, even for people with ordinary abilities like Xiao Zeng Xiaobai , The heart is also kind, and has a sense of justice to know what should be done and what should not be done.

Cui Haibin is the only one who is an exception, of course, it is another matter if he was appointed by the shuanggui.

Apart from these, this is the first time that there are problems in the whole bureau, up and down. Could it be because of the distance?

It seems that the people in the black car are likely to be the murderers in this case. Their family relationship can influence the forensic doctor, instruct director Zheng, and find professionals to clean up the scene. A deputy director even helped It's not difficult to guess where such a person is, covering up and reporting.

Not long after, when they came to a hotel, Master Wang went down to check in. Apparently, the local city bureau had no intention of making arrangements. It had reached this point. Even if they arranged, it was impossible to go there. Da Zhao went to order takeaway.

On the morning of April 4st.

Zhou Ning opened his eyes and grabbed his mobile phone. He glanced at his mailbox and received several inspection reports. The blood stains on the brick found on the top floor of the Salt Industry Company's compound were found to belong to the deceased after DNA testing.

There were also some blood samples found at the scene, but the various test results on the deceased did not come out together.

After Zhou Ning finished washing, Da Zhao also got up, rubbed his eyes and glanced at the time.

"I said, we don't need to get up at six o'clock to get ready. Don't rush Sister Cui. They are probably busy all night. I will send the inspection report after a while."

Zhou Ning nodded.

"Get up, get ready, and see how Liu Yufei and the others are busy, and if Zhang Qiuju's condition is stable, I want to go to her house to take a look."

Da Zhao was a little puzzled.

"Hometown?"

Zhou Ning nodded.

"According to what Tang Jianghai said, He Jiahong knew the people in the black car, so we have to check from the social relationship. Going to his hometown may be rewarding. Only when we find the car can we find these suspects. DNA was found on the body and it could not be identified."

Da Zhao nodded, what Zhou Ning said was the problem.

"I'll go and see if Liu Da and the others are in the hotel. You go down and have breakfast first. Bring me a copy. I'll eat it on the way. Remember two."

After finishing speaking, as if fearing that Zhou Ning would repent, he rushed into the bathroom quickly, grabbed the police uniform and ran away after washing.

Zhou Ning tidied up his supplies, opened the door, and Pharaoh came in before he went out.

"Director Zhou, you should eat in your room, or go to the restaurant."

Zhou Ning followed Lao Wang out with his bag.

"Are you all up?"

"Well, Da Zhao knocked on everyone's door, Liu Da and the others left earlier, and it was already after twelve o'clock when they came back last night."

Zhou Ning was a little surprised. Thinking of Xiaoqu, Zhou Ning hurriedly asked:

"Xiao Qu also came back in the middle of the night?"

Old Wang nodded.

"He's washing up, let's go down first."

No nonsense, quickly came to the restaurant, here are all people from their city bureau task force, the waiters were invited out, after all, it was a morning meeting, Liu Yufei waved to Zhou Ning.

"Come and sit down."

Zhou Ning went over, and Da Zhao had already put a plate for him, which was full of breakfast he could accept. Wave your hands.

"You all have worked hard, hurry up and eat first, as long as I can do a good job in logistics, anyway, there can't be waiters here. Listen, you eat quickly."

Big Zhao grinned.

"Master Wang is worthy of being a soldier. This style is my father's favorite. He is meticulous in his work and takes care of everyone's emotions. This ability is not bragging."

Zhou Ning didn't answer, and looked at Xiao Qu, who was yawning with two national treasure-level dark circles under his eyes, so tired, it was obvious that they were busy last night without any real gains.

"The vehicle didn't find the information, did it?"

Xiao Qu nodded limply.

"I tracked all the way out of Xinghua City and lost it towards the east. I could only find a general location. However, this car did appear in front of Jiulaofeng Park at 23:54 that night. This park is a free park. , with roadway.

This black car was driving directly south. It drove east in about 10 minutes. At 23:19, it appeared on the side of the road on the side of Wuzhong East. There was no driving light. It was a surveillance corner, and it was impossible to see if anyone was there. When you get down, you can see a front of the car.

I analyzed it, and calculated according to the shaking of the car, someone got off the car at 23:19, and the time of leaving for the first time was 0:22. "

Zhou Ning heard the important point, raised his head and stopped chewing.

"First time? That is to say, have these two cars come back?"

Xiaoqu nodded.

"About an hour after leaving, the car stopped here again at 3:29 on March 1, but this time it was a little further back, and the car shook more this time. The time of departure was 37:3."

Zhou Ning frowned, and recorded these time points in his notebook.

According to the analysis of this time period, at 23:12 He Jiahong went back to find the keys and personal belongings, then these people pretended to leave, but went directly to He Jiahong's house to lurk in, waiting for He Jiahong's return.

After all, the time when He Jiahong ran into the community was 23:35, and the time when the shoes fell from the monitoring was 23:37, which means that at this time, He Jiahong was not dead, maybe struggling, maybe being taken to the rooftop for threats, or even injured, However, there was no blood in the corridor, which made Zhou Ning even more confused.

What is the process?
Liu Yufei sighed at this moment, took a bite of the boiled egg, and said as if venting:
"The households in Unit [-] of Building No. [-], except for the owners of these two houses on the fifth floor, we all went in and took a look. The house is very old and there is no trace of deliberate cleaning. Do you think the first scene will be on the rooftop of the top floor ?”

Zhou Ning was silent, he was not sure, but the temperature of the roof, and the environment without sound insulation, it seemed impossible to do such a thing, thinking about the traces of the temporal fracture of the deceased, Zhou Ning waved at Da Zhao.

"Show me one more time, the scanned picture of the deceased's skull."

Da Zhao quickly opened the laptop and found the corresponding picture. Zhou Ning stared at it and said:

"The blow on the right temporal part was very powerful. Judging from the shape of the fracture, there was only one blow. Such a heavy blow would immediately cause the deceased to lose consciousness, but he would not die immediately. Intracranial hemorrhage appeared gradually. As for the time of death, I estimate that About three hours."

Liu Yufei froze for a moment, a little unbelievable.

"You mean, after He Jiahong was hit on the head and fainted, the cerebral hemorrhage did not cause her death all at once, but gradually appeared. At this time, the murderer may think that she just fainted, and after beating her, she found that she was out of breath. , faked a suicide scene because of fear?"

Zhou Ning nodded, pointed at the few time points just recorded, and narrowed his eyes slightly.

"Based on the time the black car was parked, when they returned for the second time, the deceased did not die. The deceased had intracranial hemorrhage. At the beginning, he may have fainted due to the blow, but then he would gradually develop epilepsy or lie. This movement will not Small."

Liu Yufei understood. If according to what Zhou Ning said, when these people left, they found that He Jiahong was dying, and they all panicked. But when they came back again, they had already thought of countermeasures. , they faked a suicide scene.

Of course, corresponding arrangements have been made for who will call the police after dawn, which further proves that the identity of the murderer is unusual.

At this moment, Da Zhao's computer was beeping non-stop, and Zhou Ning's mobile phone also received an email notification at the same time. Needless to say, Da Zhao had already started downloading the mail, and handed the computer to Zhou Ning.

Zhou Ning scanned it quickly, and some other information can be skipped, but the DNA of four males was found in the residues found in the nails, mouth, wrists and vagina of the deceased, of course only the DNA in the nails The male DNA matches that of Tang Jianghai.

Among the remaining three men's DNA, two of them had a DNA similarity of 25%. Seeing this, Zhou Ning was also stunned.

Liu Yufei had already leaned over and looked at it for a long time but couldn't understand what it meant.

"What happened to Director Zhou?"

Zhou Ning hurriedly said:

"I'm not surprised to find Tang Jianghai's DNA in the nails of the deceased. After all, they had contact with each other that day. After all, when we took samples, we found that the nails of the deceased had been deliberately scraped. What surprised me was that among the three people who violated He Jiahong, some The two men are related by blood, possibly brothers or cousins."

Da Zhao cleared his throat, and everyone looked at him, which made him somewhat nervous.

"I don't mean anything else. I just want to ask the next step. What are we going to do? We won't find someone in the whole city to do DNA comparisons. If we really do this, Big Sister Cui will hunt and kill Zhou Xiaozhou. How do we determine the scope? ?”
