That night, Xing San'er never closed his eyes. He always felt that the group of people might appear at any time.
Until the next morning, many police appeared on the first floor, and a stairwell was cordoned off.
The person who discovered the body was the cleaning lady who was cleaning the first floor today. She smelled a strange smell when passing by the stairwell, so she went into the stairwell and found the body.
Lu Wan let out a long breath, her face turned a little pale, not only because of staying up late, but also because of the corpse in front of her.
The male corpse seemed to have been strangled, and the female corpse's face was bloody and dented. Lu Wan felt that she had been beaten to death.
There were blood stains on the walls on both sides of the stairs, and there were two daggers on the steps. It was obvious that there had been a fight here.
Zeng Hao came over and said, "Many entrances to this stairwell are not monitored. You can go around from the third floor to another stairwell and then leave directly from there. I asked my colleagues who were guarding the exit yesterday. There were 7 people in total after 12 p.m. Individuals left there, but there are no special records.”
The task of squatting last night was to pay attention to people entering the building, so everyone would not pay too much attention to the people coming out of the building.
"Preliminary judgment is that the time of death was between 11:30 and 12 o'clock last night." Qin Youwei clicked his tongue, "How much hatred is there to beat a woman like this?"
"Anything else found?" Lu Wan ignored Qin Youwei's complaint.
"I suggest you check all the hot pot restaurants in the building." Qin Youwei said, "The two people's clothes smell of hot pot base. I guess they have eaten hot pot in the building."
As he said that, Qin Youwei took out another mask stained red with blood, "This was taken from the face of the deceased. It is a popular fashion mask now. It should be used as a logo."
Lu Wan and Ma Hongbo glanced at each other in unison.
Ma Hongbo was also there when Chen Xiaoxiao reported the situation last night. Both of them knew that Bai Mo had discovered that a woman wearing a 3D mask had followed Cao Fei.
In fact, when Lu Wan learned that there was a murder near the first floor, she was worried that it was related to the theft gang. Now that a woman wearing a mask appeared, she found some pointing evidence.
Bai Mo and Chen Xiaoxiao arrived late. After completing their investigation last night, they went home to rest according to Lu Wan's arrangement. In the morning, they learned that a murder had occurred and rushed over immediately.
Bai Mo saw the mask at a glance. Although it was covered in blood, Bai Mo was sure that the mask was the same one worn by the woman in the supermarket.
"The deceased was disfigured. Let's see if we can draw a portrait." Lu Wan pointed to the female corpse.
Arriving in front of the corpse, Bai Mo looked at the woman whose face was covered in blood and flesh.
"Unlike the female corpse at the beach, the face of the deceased this time was hit too hard, and many important points were damaged, making it impossible to draw the full picture." Bai Mo said.
Before the look of disappointment completely formed on Lu Wan's face, she heard Bai Mo's but.
"But based on the existing points, I am 90% certain." Bai Mo opened his shoulder bag as he spoke, "The deceased is the woman who followed Cao Fei in the supermarket."
Bai Mo took out two portraits, one was of a woman wearing a mask, and the other was a portrait of her face that he spent most of the night drawing.
"The picture of wearing a mask is more like a supermarket surveillance picture, and the accuracy is 100%." Bai Mo said, "The latter one is only 80% sure."
Zeng Hao took the portrait and said, "I'm going to visit the hot pot restaurant in the building and see if I find anything."
Lu Wan arranged for everyone to visit the nearby area separately to investigate all the ways to leave here, then walked down the stairs and left the stairwell.
After walking out of the blockade, Lu Wan saw Xing San'er not far away who was looking at her.
Arriving in front of Xing San'er, Xing San'er pointed to the stairwell with a gloomy face, "Is it related to Cao Fei?"
Lu Wan nodded, "I think you should cooperate with our investigation. Cao Fei is in danger now. Many people are looking for him. He may have accidentally obtained something that can kill many people."
This building is full of Xing San'er's spies, and Lu Wan knows very well that it won't be long before Xing San'er knows that the police are looking for someone with the portrait.
With Xing San'er's connections and abilities, she was able to quickly connect these things, so Lu Wan simply admitted that she wanted to gain Xing San'er's favor and get Xing San'er to join forces with her.
Xing San'er thought for a moment and nodded, "If Cao Fei comes to see me, I will take him to you."
Xing San'er was not a fool. Murder cases occurred one after another. He could also see that Cao Fei was trapped in a huge whirlpool. This was no longer a problem that a bunch of thieves could handle.
······
After returning to the police station, Lu Wan and Ma Hongbo did not rush upstairs. They stayed in the parking lot with a tacit understanding.
After everyone left, Ma Hongbo took a deep breath and said, "It seems that there is really a fourth party, and that person is the murderer of Huang Mao."
Before leaving Shanghong Building, Zeng Hao used Bai Mo's portrait to find the hot pot restaurant where the two deceased women had been. Unfortunately, only the bar in the store had cameras, and they were unable to determine the full profile of the deceased woman.
Bai Mo's inference was correct. The deceased woman was the one who followed Cao Fei in the supermarket.
In this way, the timeline is clarified.
The deceased woman learned about the relationship between Xing San'er and Cao Fei from Xiangpao yesterday, so she decided to find Xing San'er. Unexpectedly, the deceased woman was very cautious. She entered the building in the evening when there was a large flow of people and waited until after 11 o'clock to start taking action.
It's a pity that the deceased woman met the murderer in the stairwell.
"The deceased woman is a member of the theft gang. She is looking for Cao Fei, and the murderer is also looking for Cao Fei. And the murderer is not only looking for Cao Fei, he should also be looking for the theft gang." Ma Hongbo looked at Lu Wan, "What do you think? Is it possible that the murderer is someone from Beining City?"
Lu Wan bit her lip and shook her head slowly. Lu Wan did have this suspicion after learning that the deceased woman was a member of the theft gang.
Fei Wen has a cooperative relationship with the theft gang. He may have arranged for someone to follow the theft gang. After Cao Fei's accident, Fei Wen was worried that he would be implicated, so he asked his men to kill him and silence him.
But there is something unexplainable here.
The person arranged by Fei Wen must be a professional killer. The killer tortured Huang Mao in order to find out the whereabouts of Cao Fei. However, the two deceased members of the theft gang did not know where Cao Fei was, so there was no need to torture him.
If it was a professional killer, shouldn't he just strangle the deceased woman to death? Just like with the dead man.
According to Lu Wan's experience, she felt that this was more like a revenge killing.
Recalling that Bai Mo had been investigating the case in the old way for the past two days, and indeed found some important clues, without Bai Mo, they would have never been able to determine that the two deceased today were members of the theft gang.
Lu Wan suddenly had a realization. Bai Mo didn't know about Fei Wen's relationship with the theft gang, so he didn't think too much about it.
"It seems like we should really look at this case from the perspective of a normal serial murder case."
