This case discussion was held in the conference room of the Public Security Bureau. In addition to members of the Criminal Police Team, the participants included Ma Hongbo, Director Bai Yonghui and Deputy Director Zhang Shuo.
The two directors' interference in the case shows the seriousness of this incident.
The case occurred in Shanghong Building, which is a crowded public place. It immediately aroused great concern in the society.
Among them, the owner of Shanghong Building is the one who is most concerned about the case. Shanghong Building is already in decline. If there is no reasonable explanation for this murder, Shanghong Building may be over.
After asking for instructions from the two directors, Qin Youwei said: "There were two corpses at the scene. The time of death was between 11:20 and 12 o'clock last night. The male deceased was earlier than the female deceased."
"The cause of death of the male corpse was mechanical asphyxia. He was severely injured during his lifetime, with four broken ribs, brain damage, and intracranial hemorrhage. I assess that even if he was not strangled, he would have died if craniotomy was not performed in time."
"The female deceased died of brain injury, with multiple fractures on her head, and some bone fragments even entered the brain. Two daggers were found at the scene that should be the weapons of the two deceased people, with their corresponding fingerprints on the blades of the male deceased's daggers The wiped blood was extracted.”
"Can you confirm the murder weapon used by the murderer?" Director Bai Yonghui asked.
Qin Youwei frowned slightly, "I mentioned some fiber components on the temples of the male deceased and the face of the female deceased. After testing, it was found to be a fiber component of cotton and linen, which is the white gloves you commonly wear on construction sites."
"Killing with bare hands?" Bai Yonghui was startled. "The human skull is quite hard. The murderer destroyed the skull of the deceased woman with just a pair of fists?"
Qin Youwei nodded, "My judgment is this."
Bai Yonghui looked at Ma Hongbo, "The cavalry team is well-informed. Have you ever seen this kind of killing method?"
"Some well-trained masters can do it." Ma Hongbo didn't know why Bai Yonghui suddenly asked, and explained cooperatively, "I don't know what the close combat level of our special police in Meihai City is. As far as I know, some special police in Beining City It can break the skulls of ordinary people."
"A well-trained master?" Bai Yonghui nodded thoughtfully, "We do not have such masters in Meihai City. Now it is confirmed that the two deceased people are members of the theft gang. Does the horse team know the origin of this master?"
Ma Hongbo was helpless for a while, and it turned out that Bai Yonghui was waiting for him here.
This also shows that Lu Wan did not tell Bai Yonghui the information he provided, but it is not clear whether Lu Wan was following confidentiality or did not want the Meihai City Public Security Bureau to get into trouble.
"I don't think the origin of this expert is very important." Lu Wan suddenly spoke and waved her hand to Chen Xiaoxiao, "Let's listen to everyone's investigation results first!"
Chen Xiaoxiao stood up and said: "After comparison with the DNA library, we have determined that the male deceased was named Liu Chao. He was from Sanjiang Province and had a criminal record. Further investigation is underway. The blood stains on Liu Chao's dagger belong to a pickpocket named Xiangpao. It was left behind yesterday when Liu Chao asked about the cannon."
"That means they didn't hurt the murderer at all?" The person who asked the question was Ma Hongbo, his face full of shock.
Seeing the puzzled looks on everyone's faces, Ma Hongbo quickly explained: "When I was investigating them, I found out that they had two conflicts with the local underworld, but they escaped unscathed. It is said that there are several masters among them."
When he heard that there was blood on Liu Chao's knife, Ma Hongbo instinctively thought that Liu Chao had injured the murderer, but he didn't expect that it was not the case, so he was so excited.
"It stands to reason that they planned to go find Xing San'er. In order to prevent emergencies, these two people must be the most powerful in the gang." Lu Wan understood what Ma Hongbo meant, "But these two people did not hurt the murderer. "
The same thought appeared in everyone's mind - what a great master this must be!
Ma Hongbo's brows were squeezed into the character "Chuan". Such a powerful killer may not exist in Beining City. The only person who can afford such a level killer is Fei Wen, the richest man in Beining City.
"What are the results of the visit near the building?" Lu Wan asked Zeng Hao.
Zeng Hao replied, "According to the surveillance inside the building, the two deceased people left the hot pot restaurant and took the escalator to the third floor, and then walked into the blind spot of the surveillance. The entrance to the stairwell where the crime occurred is also in that blind spot."
"Is anyone following them?" Lu Wan asked again.
Zeng Hao shook his head: "Nothing was found in the surveillance, and only two deceased people walked into the entrance of the third floor of the stairwell where the crime occurred during that time."
"The murderer may be familiar with the terrain of Shanghong Building. After all, he killed Huang Mao there the day before and escaped unscathed." Chen Xiaoxiao analyzed.
Lu Wan originally had a strange feeling after hearing Zeng Hao's answer, but Chen Xiaoxiao's analysis sounded very reasonable, and Lu Wan temporarily put aside her doubts.
"I identified a person's WeChat account through their payment records at a hot pot restaurant, but the bound mobile phone number was far away in Beining City." Sun Xiaokai said, "I found the mobile phone number that logged into the WeChat account. It was a black account. This mobile phone number It is currently shut down."
"The mobile phones of the two deceased persons at the scene were missing. Is it possible that the murderer found other members of the theft gang through their mobile phones and then continued killing?"
There is nothing wrong with Sun Xiaokai's speculation. Since the murderer has taken action against the theft gang, he will probably kill them all.
Deputy Director Zhang, who had been silent all this time, his face darkened. In the Public Security Bureau, Bai Yonghui was in charge of criminal investigation, and Zhang Shuo and the other deputy director rarely interfered.
If it weren't for the excessive pressure from the secretary this time, he would definitely not come to attend the meeting.
The secretary's instructions were very clear: catch the murderer as soon as possible and no more deaths would be allowed.
"How is the investigation of the theft gang?" Deputy Director Zhang asked excitedly, "If another person dies, it will be difficult for us to explain."
Bai Yonghui looked at Lu Wan, he also knew the instructions above.
During this meeting, three people from the first team did not show up, namely Bai Mo, Yang Pengyu, and Peng Yuetao. Apparently, the three of them were still investigating the case.
"Peng Yuetao and Yang Pengyu are following an outsider named Zhu Yanchao. We highly suspect that Zhu Yanchao is a member of the theft gang, but Zhu Yanchao has not contacted anyone else since yesterday." Lu Wan replied.
"I think we should notify the SWAT team to send a few plainclothes people over for support." Zhang Shuo asked Bai Yonghui for advice. "Firstly, it can ensure that the target will not be lost, and secondly, it can also ensure the safety of the target."
Bai Yonghui nodded in agreement, "Okay."
Lu Wan glanced at her phone, which showed Peng Yuetao's real-time location. She was also worried that the murderer would find other members of the theft gang through the deceased's phone, so she kept in touch with Peng Yuetao.
Lu Wan's eyes changed after seeing Peng Yuetao's position.
After Zhu Yanchao was released yesterday, apart from finding a massage parlor to sleep at night, he had been wandering around various shopping malls in Meihai City.
But at this moment, Peng Yuetao's position actually stayed in a housing area in Xiacheng District for a long time.
Lu Wan immediately reported to Bai Yonghui. Bai Yonghui was also worried that there was a problem with Peng Yuetao, so he immediately contacted the special police detachment to send people to support.
The case discussion meeting was temporarily over, and everyone left the conference room one after another. Lu Wan and Bai Yonghui stayed away as if they had agreed.
In the blink of an eye, only Lu Wan and Bai Yonghui were left in the conference room.
The door of the conference room was closed tightly, and Zeng Hao, who was the last to leave, closed the door specially for the two of them.
"You asked for all the information about the theft gang. Is there something Ma Hongbo is hiding from us?" Bai Yonghui asked.
Lu Wan nodded slowly. She was thinking about whether to tell Bai Yonghui the direction of Ma Hongbo's investigation.
"Haha!" Bai Yonghui smiled, "You don't have to be embarrassed. Since you don't want to tell me, you must be afraid that I will be implicated, and I don't want to know either."
The tacit understanding between master and disciple was vividly displayed at this moment.
"Right?" Bai Yonghui lit a cigarette, "Why didn't you see Bai Mo? Have you arranged other jobs for him?"
"Well!" Lu Wan said, "Ma Hongbo and I shared too much information. I felt that my vision of the investigation was affected, so I asked Bai Mo to try to re-investigate this case according to the investigation ideas of serial murder cases."
Serial murder case?
Bai Yonghui looked at Lu Wan with wide eyes. He did not question Lu Wan's suspicion about the direction of the case investigation. Before the case was solved, all suspicions were possible.
"You actually asked Bai Mo to check a line alone?" Bai Yonghui was surprised that Lu Wan actually reused Bai Mo.
"Yes! He is a person who lives to solve crimes. I think he will surprise me." Lu Wan chuckled lightly, and her smile was full of charm under the decoration of flaming red lips.
······
Outside the gate of the Family Courtyard on Yaochang Street, Xiacheng District.
Peng Yuetao and Yang Pengyu sat in the car and stared at Zhu Yanchao, who was eating wontons opposite the gate.
"This kid is so damn cautious!" Peng Yuetao scolded, "He obviously didn't notice that we were following him, but he actually wandered around from yesterday afternoon to now."
"The more this happens, the more it proves that he will take us to his base!" Yang Pengyu's voice was a little excited.
Zhu Yanchao had been wandering around various shopping malls, and now he suddenly came to Yaochang Street. There were residential areas nearby. He was obviously ready to go home!
"The Army has sent support. I heard that the case is very loud now, and we might be in danger here. I think if..." Peng Yuetao suddenly stopped talking. He saw Zhu Yanchao leaving the wonton shop, He actually walked directly into the gate of the family courtyard.
The two got out of the car immediately and followed Zhu Yanchao inside.
Seeing Zhu Yanchao entering a unit building, Yang Pengyu, who was experienced in tracking, said, "I'll go up and see which apartment he entered. You wait below. I'm afraid this is a cover. You will come out after walking around for a while."
After saying that, Yang Pengyu jogged into the unit building.
This is an old-fashioned family courtyard in a factory area, with two rooms on one staircase and no elevator. When Yang Pengyu entered, he could hear people going upstairs.
Yang Pengyu quickened his pace at first, and then slowed down when he could see Zhu Yanchao's back.
Zhu Yanchao stopped on the fourth floor. He turned back and glanced at Yang Pengyu who was following behind. He had no intention of opening the door.
Yang Pengyu kept speed and passed by Zhu Yanchao, walked up to the fifth floor, randomly selected a door, knocked twice, and shouted in the pure Meihai dialect: "Mom, open the door!"
At the same time, Yang Pengyu took out his ID. If the door opened, he needed to gain the trust of the other party through the ID.
The door hadn't been opened yet, but fortunately Zhu Yanchao seemed to believe that Yang Pengyu was the resident upstairs, and Yang Pengyu heard a knock on the door.
The knocks on the door were very regular, three long and two short, like secret signals, which also showed that this was Zhu Yanchao's destination.
The door downstairs opened, and Yang Pengyu breathed a long sigh of relief. Just when he was about to notify Peng Yuetao, he heard a loud noise.
That was the sound of the door hitting the wall, and someone knocked out from inside. Then Yang Pengyu heard another man's roar.
Yang Pengyu immediately came to the corner of the stairs on the fifth and fourth floors, and happened to see Zhu Yanchao being strangled by a man with a wire and pulled into the room.
The man was wearing a cap and a mask. He heard Yang Pengyu's footsteps and looked up at Yang Pengyu.
"Don't move!" Yang Pengyu yelled and pulled out a pistol, but he found that the man in the peaked hat also took out a pistol.
boom!
