Bai Qiheng turned on the flashlight, the light shone on the wall of the store, he found that there was an indoor switch, after turning on, the room became bright, this is a small kitchen of ten square meters.

"Boss, I'll go with Nanfeng to take a look." Bai Qiheng asked.

"Well, go ahead." Luo Shixian asked An Ningshuang to wait for a moment to speak, and responded to the male team members.

With the permission of the captain, Bai Qiheng and Sheng Nanfeng stepped into the door. Previously, when checking Zhao Tianyong's information, the police had learned that the "Providence Communication" was the joint property of Zhao Tianyong and Xu Ruyi.

In the course of investigating and handling criminal cases, the police may carry out corresponding investigation work according to the specific circumstances of the case. This means that after the police did Zhao Tianyong participate in the planning of the murder of the four women, they had the right to directly search the residence of the criminals.

"Boss, according to the colleague who recorded the statement at the scene of the crime, the employees of the café did not know that there was a basement in the backyard. Usually, they can also go in and out of the backyard at any time, and they don't find anything abnormal. However, some employees also said that Wan Xiaoting and Wen Qianqian have a good relationship, and may know more than them. An Ningshuang saw that several people had finished communicating, and immediately spoke.

"Hmm." Luo Shixian nodded and asked guidedly: "Who is the storefront of the café?" ”

This is Wen Qianqian's own property, with a solid family background and hundreds of millions of assets, she is the only daughter in the family. At present, her parents are not in Kujiang City, and our colleagues have informed the parents of the deceased that the two have booked the earliest flight back and are expected to arrive today. An Ningshuang recounted the information she had found.

At this time, her sleepiness dissipated a lot, and she continued, "Boss, I asked the toilet manager, and he said that it was almost last September, and the government document came down to expropriate land to build public toilets. During the construction process, due to the mistakes of the construction personnel, the shared area of the toilet was half a square meter more than the original plan, which happened to occupy a little bit of the backyard of the café. After the incident, Wen Qianqian, who was already strongly opposed to building a public toilet at the back door of her house, immediately approached the contractor to theorize. In the end, the government intervened to mediate between the two parties, locked the back door of the men's toilet, covered it with paint to the same color as the wall, and the back door of the women's toilet was not installed. By the way, the backyard of the café was originally only fenced, but Wen Qianqian built a fence because of this incident. ”

"And then?" Luo Shixian answered.

The administrator said that on his first day on work, Wen Qianqian asked for a key to the back door of the toilet, and unreasonably said that she also had a share here. After all, the back door of the men's toilet is her backyard as soon as it opens, even if most of the guests think that only the iron door on the other side is the exit. An Ningshuang showed a rather speechless expression.

It turned out that this was the reason why Wen Qianqian had the back door key to the toilet.

Su Zhiqian thought secretly in his heart, and soon heard a female voice again, An Ningshuang said again: "The information about the cleaner of the toilet has been found, there is nothing suspicious, a retired man in his sixties, living on Xin'an Road." By the way, Boss, you've been to the Administrator with Forensic Doctor Su! ”

"Yes." Su Zhiqian nodded, and quickly added, "Frost, what's wrong?" ”

"It's gone!" An Ningshuang waved her hand and explained: "The old man told me that the police asked him a few questions during the day, I think it must be you and the boss, he said that he didn't make it clear, and you left, so I asked for the answer for you." ”

"You say." Luo Shixian acquiesced to her guess and said in a deep voice.

"Well, the cleaner is a woman, about one meter fifty-seven. Also, the administrator said that the key did not know when it was stolen. Because the back door of the toilet has never been opened since it was built. An Ningshuang finished explaining the tasks assigned by the captain and breathed a sigh of relief.

When the words fell, Luo Shixian's eyes showed surprise, and he didn't speak for a while.

Su Zhiqian saw that he showed a rare silence, and she was concerned about the case, and said, "Team Luo, do you think there is something wrong?" ”

Luo Shixian came back to his senses, looked down at the short-haired woman, and said, "I suspect that the suspect's identity is a cleaner, and now it has been denied." ”

Su Zhiqian was stunned for a moment, she didn't know the details of what happened after Xiaolu escaped, and asked, "Team Luo, why do you think so?" ”

"There is a window in the toilet that is 1.8 meters long, and there is no dust on it, and a woman of 1.57 meters cannot get that high." When he heard his colleagues from the second team talk about the height of the window, this question had already popped up in Luo Shixian's mind.

"Team Luo, listening to you say this, ruling out that the cleaner is the murderer of the serial murder, we can come to another answer, the suspect was in the toilet at the time." Su Zhiqian speculated according to the train of thought given by the man.

"Hmm." Luo Shixian nodded in agreement, and then, he sorted out the case and said, "The suspect met with Xiaolu in the toilet, and he helped Xiaolu escape." After that, Xiaolu went in from the backyard of the café to find Wen Qianqian, and the two left together, the time was around 9 o'clock in the evening, and we met Xiaolu in the hospital at about 11 o'clock in the evening, what happened to the two during this time? ”

"Wait a minute, Boss." An Ningshuang, who had seen all the surveillance, spoke up, strengthened the timeline of the case, and said: "The exact time when Xiaolu attacked me was 8:45 p.m., the time she entered the toilet was 8:50 p.m., the time she met Wen Qianqian was 9:02 p.m., and the time she appeared in the hospital was 10:53 p.m. ”

"Hmm." Luo Shixian responded.

Su Zhiqian listened to the analysis of the two, and couldn't help but ask again in confusion: "Team Luo, do you mean that Xiaolu didn't stay in the café?" ”

"Forensic Doctor Su, are you thinking about Xiaolu saying that she cooked porridge for Xu Ruyi in the kitchen of the café?" Luo Shixian asked.

"Yes, Team Lo." Su Zhiqian nodded, she had heard Luo Shixian's interrogation, and it was not strange that the two of them could think of the same thing.

"Damn, how can this Xiaolu be the same as Zhao Tianyong, lying a lot." An Ningshuang was so angry that she grinded her teeth, and the whole person was completely sleepy.

Luo Shixian first glanced at the team members, retracted his gaze, looked at the store, and said, "If it's casual nonsense, we can ignore it." However, the words of the two men are related to four cases, and we must find out the reasons for their lies. ”

Su Zhiqian didn't look at the person who spoke, but she understood the meaning of the man's words. Indeed, if Zhao Tianyong and Xiao Luken had told the truth, the case would not have been so complicated.

"Boss, you're right, we must work hard to solve the case as soon as possible." An Ningshuang nodded, and she cheered everyone up with her cheerful personality.

The other people standing in the courtyard nodded, and at this time, there were footsteps in the store, and several people saw Sheng Nanfeng walking towards the door, and said as they walked: "Boss, there is a major discovery!" ”
