The case analysis meeting continued, Lu Ke turned to Ling Zizhen and asked, "What about the traces at the scene?" ”

Ling Zizhen replied: "This is also the only difference from Sun Hairong's case, the technical team found a footprint at the scene of this crime, the footprint is very shallow, not clear, can only be judged to be a forty-two size shoe print, but the sole style and the type of shoe can not be distinguished for the time being." ”

As he spoke, he used a projection device to show the footprints: "The scene of the crime this time is on the side of the road at the head of the bridge, and there is part of the dirt ground. And the murderer's time of committing the crime was late at night, and there were no street lights nearby, so the murderer should have left it inadvertently. ”

"Can you infer the height and size of the murderer based on the footprints?" Lu Ke asked.

"Because there is only one set of footprints, there is no way to guess by stride spacing, only based on human bone data. The murderer's height was about 1.75 meters, and there were no typical signs of wear and tear on the soles of his shoes, indicating that the murderer's legs and feet were not diseased. Ling Zizhen said in a deep voice.

Lu Ke sighed and asked again, "In addition to this footprint, is there any DNA evidence such as hair and saliva?" ”

Ling Zizhen shook his head and said, "No, the crime scene is very clean, and the murderer left quickly after the murder and did not stop at the crime scene." In other words, it took a very short time for the murderer to leave from the time he killed. ”

"What about the victim's property?" Lu Ke continued to ask.

"Not lost."

Lu Ke closed his eyes slightly and took a deep breath.

At this time, Mo Yufei suddenly asked: "Sun Hairong is eating at a barbecue restaurant, so why is Tian Minglang not going home at half past ten?" ”

Ling Zizhen explained: "By the way, the technical team found a consumption receipt for a bathing center in Tian Minglang's pocket, and the place of the crime is not far from the bathing center, he should have just left the bathing center." ”

Immediately afterwards, Su Simeng spoke at the right time: "I have carefully observed the road section near the crime scene, and about 100 meters to the north, there is a bathing center, which can be said to be the most high-end bathing center in Lehua County." The bathing center membership card in Sun Hairong's wallet is from that one. Leaving the bathing center and walking south across the bridge, which is the main road, Tian Minglang should have been about to go to the main road to take a taxi home, but was killed on the way. ”

Everyone briefly discussed according to the existing clues, but did not discuss the reason, and after a short silence, everyone turned their eyes to Lu Ke.

Lu Ke calmed down and said in a deep voice: "There are still too few clues at present, both cases happened at night, and they were both in unmonitored sections, and the hope of finding eyewitnesses or other residual clues is relatively slim." However, it is still necessary for the police officers in the hard team to do as much as possible to visit the vicinity of the crime site and expand the scope of the investigation. Notify the technical investigation department, and obtain monitoring to cooperate with the investigation. ”

The criminal police of Lehua County Public Security County, who participated in this case analysis meeting, nodded their heads and made records.

"At present, it has been determined that this is a serial murder case, and there is a deep contradiction between the murderer and the chengguan, and it can even be said that there is hatred. But the murderer's target is not random, he follows the target after identifying it, looking for an opportunity to attack. So, who will have an intersection with the chengguan, and there are contradictions and hatred? Lu Ke analyzed, and suddenly threw out a question.

Mo Yufei replied, "Vendor." ”

Lu Ke nodded, revealing a firm gaze: "That's right, the murderer is most likely a trader, or has been a trader." The most important thing is that he must have been dealt with by the urban management law enforcement team, not limited to the near future. We should expand the scope of the investigation and communicate with the city administration to verify the county-wide law enforcement records of the past five years. ”

"Comrades, we must speed up the progress, according to the current situation of two cases in two days, there is a high probability that the murderer will continue to commit crimes. If there's nothing wrong with that, just disperse. ”

After Lu Ke finished speaking, everyone left the conference room with their respective tasks.

At this time, only Lu Ke and others were left in the conference room, and each of them had a very ugly face, and this time, they undoubtedly encountered a problem.

Lu Ke leaned back in his chair, twisting his fingers in his hands, closing his eyes and pondering.

After a while, he suddenly opened his eyes and sat up suddenly: "What about Tang Mengxue?" Where is she? ”

"She should be in the office, after all, she can't attend our case analysis meeting." Su Simeng said casually.

"Go, call her." Lu Ke commanded.

Mo Yufei sighed, got up and went to find Tang Mengxue.

Within a few minutes, Tang Mengxue followed Mo Yufei into the conference room: "Captain Lu, are you looking for me?" ”

Lu Ke nodded, beckoned to her, and motioned for her to come over and sit down.

Tang Mengxue didn't know why, and thought that Lu Ke had some secret mission to give her.

"When you went to set up a stall yesterday, did you shoot a video?" Lu Ke asked.

Tang Mengxue was stunned for a moment, and said in a daze: "Is there a video of the city's violent law enforcement?" Yes! The whole process is recorded and videotaped. ”

Lu Ke glanced at the projection equipment on the conference table: "Copy the video, let's take a look." ”

Although Tang Mengxue didn't know Lu Ke's original intention, she still did it.

However, Mo Yufei seemed to understand, and said, "Are you looking for a suspect?" ”

Lu Ke nodded and said in a deep voice: "The two deceased were both in law enforcement in the morning and were killed in the evening. It is an obvious revenge killing, and the chengguan is the target of the murderer, and he is fighting for the traders. Therefore, he must have witnessed the violent law enforcement of the chengguan, that is, in the process of enforcing the law, he must have been at the scene. If he wasn't a trader, then he must have been in the crowd of onlookers at the time, silently watching everything. ”

"Having said that, we currently have only one footprint in our understanding of the murderer, gender and height are relatively vague speculations, there are so many onlookers at the scene, how to find it?" Although Su Simon agreed with Lu Ke's investigation idea, he still gave a very realistic problem.

"It depends on our professional reporter comrades, and the ability to shoot unannounced interviews." After Lu Ke finished speaking, he motioned to Tang Mengxue to start playing the video he had taken.

Tang Mengxue operated the laptop, pressed the space bar, and the video started playing.

I have to say that Tang Mengxue's unannounced interview shooting is absolutely professional, the picture is clear, the lens is very stable, and it is in an excellent position for wide-angle shooting.

Under Lu Ke's instructions, the video kept fast-forwarding and stopped at the moment when the chengguan enforced the law.

At this time, various sounds came from the video, sirens, horns, swearing, arguments, and pleading......

Although everyone did not experience this incident at the scene, through this video, they learned all about the law enforcement of the chengguan as if they were there.

But everyone didn't have time to evaluate the law enforcement behavior of the chengguan, and everyone's eyes fell on the onlookers at that time.

"There are not 50 people, but there are 30 people, and there is no guarantee that all of them will be filmed." Ling Zizhen stared at the video, shook his head, and looked embarrassed.

Lu Ke stared at the video and said seriously: "This is the only clue we have at present, hand over the video to the technical investigation department for frame-by-frame interception and analysis." Let the police investigating law enforcement records speed up and see if they can compare some clues. ”
