Captain's Road to Attack

"When did you die?" Cheng Gong asked.

"According to the degree of blood coagulation, it should not exceed three hours." Zhu Ci'an said.

Afterwards, the body temperature and rigor mortis were checked again, which verified the result of his speculation just now.

Hearing this, Cheng Gong immediately called Li An over and asked, "When did you get here? Did you see anyone walking out of the gate when you were staying?"

Li An couldn't help being taken aback when he heard the words, he understood what was going on as soon as he heard these words.

"Boss, are you saying that the murderer left under our noses??"

"Don't talk about this first, did you see it?" Cheng Gong pointed to Li An and asked.

Li An tried his best to recall, and said: "My people and I just came here not long ago, just over an hour, and no one came out of the gate of this building."

Cheng Gong was not annoyed when he heard the words, but just sighed lightly, there was nothing he could do if he missed it.

Then Cheng Gong looked at Zhu Ci'an, saw that he was still studying the head, and asked, "Is there something wrong with this head?"

Zhu Ci'an looked up at Cheng Gong, tilted his head and said in confusion, "Do you still remember when the killer killed the second person?"

"Remember." Cheng Gong said.

"This time the knife edge is exactly the same as last time, except for the absence of the gun and the intentional reverse, it can basically be identified by the same person." Zhu Ci'an said affirmatively.

Hearing this, Cheng Gong fell into deep thought, and his expression became serious.

"If it's really that guy, we have to speed up the pace. The third person to die is probably the real culprit behind this case." Cheng Gong murmured.

Luo Hongbo next to him didn't intervene, and asked strangely when he heard Cheng Gong say this: "What do you mean by that? Can you explain it a little bit more clearly?"

Cheng Gong glanced at Luo Hongbo and said: "Although the killer's pattern is not yet certain, judging from the current situation, the killer first helps the murderer to take revenge on the murderer, and then ends the murderer's murder. The logic of murder, but the most important thing right now is to find out who the murderer is, if we can leave him alive earlier, there will be traces to follow when we catch that killer again."

"That being said, all doubts now point to Xu Tian, ​​and now he is dead, and all clues are broken." Luo Hongbo frowned when he saw this.

"Boss, we can check the videos of all the cameras around here." Ma Tao of the second team said to Luo Hongbo.

Seeing that Cheng Gong and the others didn't have much reaction to this, Luo Hongbo said, "You don't seem to have any hope for this?"

Li An smiled wryly and said: "I really hope to see clues in the surveillance, but judging from past experience, this killer has very strong anti-detection capabilities, and the reason why he did it today is definitely not impulsive."

"No matter what, you have to look to find out, what if you miss it?" Luo Hongbo said.

Cheng Gong also nodded and said, "That's right, we can't let go of a possibility."

At this time, Cheng Gong said to the officers of the trace department who were checking the fingerprints: "Don't check the fingerprints, first look at the footprints on the ground."

A team leader of the Trace Section nodded upon hearing this, and said to Cheng Gong, "Leave the two of us, and the rest go out. You can come in after we finish the inspection."

Cheng Gong nodded, and everyone withdrew.

Xu Tian's residence is a high-rise residential area, so a group of people gathered in the corridor after leaving Xu Tian's house.

Fortunately, this is a high-rise building, so residents almost always take the elevator when they go downstairs, which has no effect on Cheng Gong's work. However, as time went by, news of the dead people in the building spread like wildfire, and soon some people became curious. Came over to see what happened.

However, as soon as the elevator door opened, there was an obvious yellow boundary bar, and I couldn't see anything except poking my neck around to look around.

There is also a bizarre version of the story, saying that Xu Tian's family was charged with evil spirits, his son committed suicide a few days ago, and Xu Tian had another accident today. I heard that Xu Tian's wife didn't come home last night, and the accident probably happened as well.

Hearing the chatter from downstairs, Lu Feng really couldn't help but shake his head, he could say anything so confidently without any basis, and then the listeners would believe it without any doubt.

Then Ma Tao reported to Luo Hongbo with his notebook: "Boss, I have just obtained the surveillance records of all the cameras in the last 24 hours from the building property. This is a high-end residential area, so the security is relatively standard. There must be a residential area at the entrance of the residential area." The key cards issued by residents are only acceptable, and all public areas and gates are monitored by cameras. I think this time the murderer will definitely appear on one of the cameras as long as he enters the gate. There are security guards under the building. Both of them There will be regular patrols at night, and if there is a change in the position of the camera, they will go out to check as soon as possible.”

Luo Hongbo nodded, "Then assign people to immediately check all the camera recordings in the last three hours, and report any clues immediately."

"Yes!" Ma Tao replied immediately.

Cheng Gong also said to Xiaopang and the others: "You guys go too."

Xiaopang, Liu Xin and others nodded and walked over. Ma Tao's computer screen was too small after all. Fortunately, Xiaopang had the foresight to take the mini projector in the bureau. Play multi-frame video at the same time, as long as you have enough eyes, multiple people can cooperate and observe at the same time, which makes it easier to find the suspect's route.

When Ma Tao saw Xiaopang's "artifact", he was a little excited, he was a bosom friend! !

Xiaopang smiled shyly, and after skillful operation, sixteen grids of images were immediately reflected on the wall, playing in sync, and the time was three hours ago.

So in front of this wall, more than a dozen pairs of eyes divide the work of the screen that they are responsible for, staring at each frame of the screen together, for fear of revealing any clues.

It is played at five times the speed of the time. As soon as someone sees a figure, they will stop immediately, and then resume the normal speed. After careful observation and investigation, continue to fast-forward and observe.

Under the watchful eyes of everyone at such a speed, two figures immediately caught everyone's attention.

"Stop!!" Almost several people shouted at the same time, and everyone else became nervous with that momentum.

Cheng Gong and Luo Hongbo stood side by side behind the crowd and observed all the scenes. When this voice was yelled out, they also yelled out at the same time.

"Cut to the second screen and zoom in." Cheng Gong ordered.

Xiaopang immediately carried out Cheng Gong's order.

At this moment, it is none other than Yan Xuemin's conspicuous and unusual appearance that is reflected on the screen.

And there was a man standing next to him. This man was wearing a black baseball cap, a black mask, sunglasses, a black leather jacket, black pants, and black leather shoes. His whole body was in black and he was armed to the teeth.

"Yan Xuemin??" Liu Xin was surprised immediately.

But Cheng Gong and Luo Hongbo didn't show the slightest surprise when they saw this man's face.

On Luo Hongbo's face was an expected smile of "it really is him". Cheng Gong was expressionless. He glanced at his watch, then at the time on the screen, narrowed his eyes and said, "Fast forward the time!" .”

Fatty didn't react until he heard Cheng Gong's order, and the screen immediately fast-forwarded again.

But Yan Xuemin's face did not appear until the end of the scene.

Luo Hongbo looked at Cheng Gong, this situation can only explain one thing.

Cheng Gong naturally thought of it too, he slowly glanced behind him, and then looked around at the police officers around him.

Cheng Gong's eyes were frightening, and even a person with a clear conscience would look at him with chills.

Luo Hongbo also looked around like Cheng Gong, and at this time everyone couldn't help but look at the people around them, looking for the ghost?

But Cheng Gong and Luo Hongbo didn't find anyone suspicious after looking around. Even if the people under him were not as close as Lu Feng and Liu Xin, their names and faces were impressive.

Suddenly Cheng Gong suddenly turned around and walked towards Xu Tian's room, Luo Hongbo also immediately reacted and ran towards Xu Tian's room immediately.

When he opened the door, he found that people from the Trace Department had passed out on the ground. Cheng Gong stepped forward and touched the carotid artery of one of them, and he was relieved when he found that his heart was still beating.

Then I saw that Xu Tian's window screens had been pulled up, high enough for people to come in and out freely.

Cheng Gong ran to the window, looked down, there was no rope, looked up again, and found that there was a special fire ladder not far away.

Without even thinking about it, Cheng Gong immediately turned around and shouted, "Where does this fire escape lead to?"

At this time, no one could answer Cheng Gong's question, only Xiaopang retrieved the architectural drawing of the building as quickly as possible to check the route of the fire escape, even so, he was sweating profusely.

"Boss, the fire escape leads to the top roof." Fatty blurted out quickly.

Cheng Gong immediately said to Li An, "Go to the rooftop."

Immediately after Li An made the order, he ran up from the fire escape like the wind.Because Xu Tian lived on a relatively high floor, it might not take long to wait for the elevator, and Li An didn't plan to wait at all.

After arriving at the rooftop, Li An and several police officers searched around but couldn't find anyone.

Just when Li An was about to report to Cheng Gong, he found that the other side of the building where Xu Tian lived was washing the wall, and several construction cleaning workers were slowly rising from below on a ladder.

At the same time, Li An saw two figures downstairs, one black and one Yan Xuemin who was dragging his white coat and hat.

In desperation, Li An immediately reported this important situation to Cheng Gong. Upon hearing this, Cheng Gong immediately called the traffic police to help set up a card to stop the transportation of Yan Xuemin and the mysterious man in black.

At the same time, Li An watched the man in black and Yan Xuemin leave Xu Tian's family area at high speed on a motorcycle.

At this time, Cheng Gong, Luo Hongbo and others immediately went downstairs to pursue them in a car. According to the information about their appearance and motorcycle provided by Ang Li, it is not impossible to catch up.
