Don't pick up your boyfriend at the crime scene

He Yanzhao is small in stature and thin in stature. He is a typical type that girls will envy. He is not a picky eater. He does not eat instant noodles like Wei Qichen. He only eats stewed chicken noodles with mushrooms. He has a good appetite since he was a child. There are many, and the most delicious barbecue and hot pot must be accompanied by a bottle of iced Coke.

Because the family conditions are not bad, and his grades were good when he was a child, so his parents let him go, thinking that their children can eat whatever they like. The only worry is that what he eats is too unhealthy for fear that it will be bad for his health in the future. But I didn't know that going back to the physical examination was another green light, and I didn't see excess fat and turned into a chubby man.

This is probably the proud son of heaven in the legendary foodie world. Normally, a person who can eat better than Wei Qichen can actually look like this, with a small face that is not even as big as a palm. This is really amazing. ........ Let all the lesbians in the city bureau feel unwell and slightly fat because of working day and night upside down.

The two hadn't hugged each other for too long, Wei Qichen just rubbed the top of He Yanzhao's soft and fluffy hair with his hands for a while, feeling tired and crooked enough, plus there are more important things to do during working hours , so he let go of his hand, and then carefully restored the other's hairstyle to its original state.

Wei Qichen asked, "Why do you suddenly think of coming to the scene of the crime?"

He Yanzhao raised his hand and scratched his hair, "There is no news about Brother Lin being kidnapped, I can't sit still in the dissection room by myself, I want to comfort Brother Zongjie but I don't know what to say, I feel very uncomfortable, so I just thought about going out and doing something.”

Sure enough, it was because of Han Lin. He is a close brother after all. When encountering danger, he felt anxious and felt a little restless? It's normal. Wei Qichen nodded, and he comforted him, "It's okay, Han Lin won't be alive for the time being. Dangerous, our tracking team has started to trace out from the monitoring at the intersection of the hospital, and we will soon find out where he is."

He Yanzhao raised his eyes, and he looked at Wei Qichen, "Why are you so sure that Brother Rin must be safe?"

"The drug dealers arrested him for a purpose, not just as a simple hostage, because he has mastered the technology of drug production and is currently recognized by the police and drug dealer gangs as the only person around us who can make drugs. Those gangs of desperadoes Doing so many bad things is all for money, do you think they will smash their own money printing machine?"

This? There is some truth in what he said. He Yanzhao felt a little relieved after hearing this, and he let out a sigh of relief, "I don't ask for anything else, as long as you are safe and alive."

After circling around here, Wei Qichen squatted down and took a look. The dismantled steel plate that was lying on the ground and used to splice the ceiling did indeed have a few thin black pieces stuck at the corners. He didn't reach out to touch the hair. This is the evidence waiting for the colleagues in the search team to take away with professional tools.

"I do know that the victim was brought up to the ceiling from here." Wei Qichen stood up and clapped his hands, "But what happened to the other person?"

He Yanzhao suggested, "Why don't we go to the women's restroom again? Well, this is not a supernatural event. The murderer can't disappear out of thin air. As long as he appears, he will definitely leave traces. Just look for it again. Think we'll be able to crack the modus operandi."

Wei Qichen followed He Yanzhao out, he said, "I also know that as long as he shows up, he will definitely leave traces, and if he can't find traces now, it proves that the murderer must have cleaned up the scene after committing the crime, but how did he clean up? There are people on the sixth floor at that time, how can he guarantee that no one will come in the women's restroom?"

He Yanzhao asked, "Hey, by the way, who were there on the sixth floor when the incident happened?"

Wei Qichen thought for a while and said, "One cleaner, two patrolling security guards, your brother Zong Jie, and a female secretary, but that female secretary left the company at ten past ten."

He Yanzhao said, "There is a female secretary, and the cleaning lady is also a woman. Compared with the female secretary? The cleaning lady may go in and out of the women's bathroom more frequently. The murderer has to call people into the bathroom first, and then kill them to deal with the wounds on her body." If he wants to accomplish so many things and avoid people who may enter at any time, how many minutes must he control the entire crime time to completely avoid accidents? What happened??"

"This may require a few more people to do different on-site simulations before we can draw a conclusion." Wei Qichen walked into the women's bathroom as he spoke, "However, your suspicion is not unreasonable. The murderer did something. ?It is impossible for him to not consider any possible accidents with such meticulousness. Could it be that this cleaning lady enters the women's bathroom for cleaning every day is very regular?"

"Why don't we ask Auntie Cleaning." He Yanzhao said, "I don't believe that someone is so regular that he can be accurate to the minute. Even if you get up on time every day, eat on time and go to work on time, there is no guarantee that you will arrive at the office in the end." The hours, minutes and seconds are exactly the same, right? There will always be accidents in life, how can there be so many 100%."

"En!" Wei Qichen nodded, and he called Chen Lin and asked, "Can you still contact the cleaning lady who is in charge of the crime scene on the sixth floor?"

At this time, Chen Lin was still watching the surveillance video with his eyelids stretched. He felt that he was only one step away from going blind. When he heard Wei Qichen's question, the child was still a little dazed, but he quickly realized it. Then he replied, "Ah? Aunt Cleaning? I put her back after the interrogation was over that day. Team Wei, if you want to find someone? Go to the property management area on the first floor of the AC building. The cleaning aunt and security patrol in the whole building There are unified arrangements, and this part of the staff is managed by the building administrator, and enterprises and shopping malls are only responsible for paying property management fees based on the square meter.”

"Oh!" Wei Qichen turned his head and raised an eyebrow at He Yanzhao after hanging up the phone, and said, "Let's go, go to the first floor and ask."

The shopping mall did not reduce the flow of people because of the murder case. Along the way, there were still many customers entering the entrance of the shopping mall. Wei Qichen pulled an elevator and the management staff asked the location of the property management office. It's a smooth walk.

"Oh, you said the cleaning aunt on the sixth floor, after the incident, she said she was too scared, so she resigned." The property manager cooperatively searched the employment roster, and then he said to Wei Qichen, "But it's unlucky to say, The cleaning aunt on the sixth floor fell to her death because she accidentally stepped on the hollow manhole cover when she came home at night. We managed to recruit a new aunt, but it happened again within three days of working.”

"It's been less than three days?" Wei Qichen and He Yanzhao were surprised together. After they shouted this sentence, they looked at each other in disbelief.

"Yes." The property management staff continued, "You also know how much the cleaning can earn. The wages here are only about a thousand yuan higher than those in other places, but this is all hard work. Especially the white-collar workers in the office buildings above the sixth floor, if the sanitation is not in place, they will complain. This is a big customer and cannot be offended, so we have a set of special requirements for these aunts, such as the ground. There are strands of hair, and there must be no peculiar smell in the toilet. Every 10 minutes, you must enter the toilet for inspections, and you will be deducted 100 yuan for each complaint. It is also because of the high requirements that it is difficult to recruit people. I don’t know when the case upstairs will be handled. It's over, but you police must not be able to hold down other people's land and prevent them from doing business? No, my cleaning lady has not been recruited yet, and I am still worried that if the police close the team one day, I will not clean here. What can I do if I go to clean up for others?"

Wei Qichen was speechless.

Originally, there is no 100% statement about rules. After all, accidents are everywhere, but at least having rules to follow is much better than blindly trying to get lucky.

But the murderer was facing a cleaning aunt who had just joined the job for three days. Could he dare to avoid all accidents in this place and kill people directly by grasping the three-day rule?

Wei Qichen didn't believe it.

He Yanzhao asked the property management staff, "Auntie Cleaning should have retained information when she joined the job, can you show us her information?"

"There are documents." The property management staff casually flipped through the stack of documents next to his hand, but it was easy to find. After turning a few pages, he found the registration information of the cleaning aunt. He reached out and picked up the paper Handed it to He Yanzhao, "That's all, thanks to you guys coming early, I'll be free in a few days to clean up the materials, and I'll just throw away the things of those who don't do it."

He Yanzhao glanced down at the information on the page, then he raised his head and said to Wei Qichen, "It's all written by hand."

Wei Qichen frowned. He understood what He Yanzhao meant. It would be easy to falsify the information filled out by hand. If the cleaning aunt had problems herself? If you want to find the person targeted by the police with such a note, it is tantamount to finding a needle in a haystack .

So He Yanzhao did not give up and asked again, "Employees must buy insurance when they join the job, have you registered these data with the Social Security Bureau?"

"Hey, there is no one who buys insurance just three days after joining the company. We have to work here for at least three months and perform well without being complained. The company will provide the service of buying insurance for aunts who are confirmed to be able to do it for a long time. That's it. She left in three days, and whoever is full will buy insurance for her."

Even so, Wei Qichen still took a photo of the hand-filled information of the cleaning lady who had only been working for three days, and he sent the picture to Chen Lin, and edited a section to ask him to check the ID number and Although the mobile phone number did not report any hope, Wei Qichen's heart sank uncontrollably when he learned that the two numbers did not exist.

This trip came to nothing, so Wei Qichen and He Yanzhao had no choice but to turn around and walk upstairs again.

He Yanzhao asked, "So we can include this cleaning lady among the suspects now, right?"

Wei Qichen nodded, "Well, there must be something wrong with her, so when the murderer committed the crime, was she in charge of looking out or helping to clean up the scene?"

He Yanzhao said, "It's not necessarily necessary for someone to look out. The cleaning aunts in our city bureau are all women. Occasionally when I go to the bathroom and see them cleaning inside, they will put up a sign for suspension of use at the door. In such a situation, most people would avoid going to the bathroom upstairs or downstairs, would the murderer avoid accidents in this way?"

Wei Qichen frowned, "This possibility cannot be ruled out."

After speaking, he seemed to think of something, and a few scattered fragments flashed through his mind instantly. Wei Qichen stopped his upward steps, and he quickly took out his mobile phone and called Chen Lin again, "Hi, Chen Lin Lin, the last time I asked the video analysis team to capture the video for me, it started with Lin Jinshu chasing someone into the AC building, recaptured the pictures captured by the front cameras and sent it to me immediately."

Chen Lin was dizzy, but he still answered, "Okay."

Within 3 minutes after hanging up the phone, the message quickly arrived on his mobile phone. He Yanzhao only heard a crisp 'ding', and then leaned his head to see what surveillance screen Wei Qichen wanted. After clicking on the message, he found It was a long picture, and after swiping it from left to right, He Yanzhao shouted in surprise, "Auntie Cleaning?"

Although she couldn't see her face, the blue overalls could confirm her identity.

Wei Qichen suddenly realized, he stretched out his hands to pinch He Yanzhao's shoulder excitedly, "No wonder I watched the video last night and didn't see anything strange. It turns out that this person is by our side, just because he is so inconspicuous." , just because she reported the case, so we didn't suspect her at all from the beginning to the end, so we couldn't find any suspicious people who came in and out. Do you think it's strange that a cleaning lady appeared in the mall with a mop Yes? She can block out all possible accidents with a suspended sign. It is not surprising that she appeared at the scene of the crime, and it is not surprising that she cleaned the scene of the crime. It is because of her preconception that she killed two men People must be a man, so we never considered the possibility of women committing crimes."

Because Wei Qichen was too happy, He Yanzhao couldn't help laughing along with him, "This is just speculation, there is no evidence, and you are so sure that the murderer must be her?"

"It's her, it must be her." Wei Qichen's eyes were shining when he spoke, he grabbed He Yanzhao's finger again, dragged him and walked quickly towards the crime scene, "Look? Come and see , I couldn't figure out anything at first, but if the murderer is her?, then everything makes sense."

The blood in the room where the murder happened has dried up, Wei Qichen did not enter the destruction, he just walked into another room next door with He Yanzhao to simulate the scene, then pointed to this place and said, "Look? From the surveillance video, I can see that the woman in the intercepted picture is short and thin, and the bathroom space is not too big. If there are two tall men standing here, there must be some degree of congestion."

Wei Qichen is about 1.8 meters tall, and He Yanzhao is about 1.7 meters tall. Both of them are not too fat or strong, but they entered the compartment together and locked the door with their hands. All seem a little difficult.

He Yanzhao looked at the closed door and said, "I remember that when I came for the autopsy that day, there was a lot of blood splattered on the inside of the door, so it can be proved that the murderer locked the door when he committed the crime, although she may have used the identity of the cleaning aunt Eliminate some people who would accidentally enter during her crime, but there should be no 100% sure that there will be no accidents? , and then locked the door.”

Wei Qichen nodded, and he looked around the small space, "The two of you are standing inside, and you still have to talk for a few words, no matter whether the result of their conversation is pleasant or unpleasant, the man will turn around and leave first. The murderer should have put on gloves, or she had already changed into the clothes she was going to use when she was waiting for someone."

His gaze was fixed on a hook on the left hand side of the partition board, Wei Qichen pointed to this hook and said, "Maybe there is a backpack hanging here, which contains clean replacement clothes, or the bag is in the next compartment, and she puts it on." After the glove crime was over, he used the string to pull his clean schoolbag over, then changed into clean clothes, and then went out."

He Yanzhao recalled the details of the day of the crime, he said, "I remember that except for the cubicle at the scene of the crime, no trace of blood was found in the rest of the place, so the murderer must ensure that she is clean when she walks out of the cubicle. Yes, and then use a mop to wipe the footprints from the outside of the bathroom to the inside. After all the unfavorable evidence has been dealt with, she pretends that she is still working, and panickedly reports that the victim's body has been found. During this period, the crime tools and blood-stained clothes have been moved away."

Wei Qichen nodded, took out his mobile phone and called Chen Lin again.

"Confirm the surveillance video. On the night of the incident on July [-]st, after the cleaning staff accepted our interrogation and left the scene, the images captured by the surveillance video were extracted and sent to me immediately."

Chen Lin is still doing business? He is very efficient. His colleagues from the search team on the scene are all there. He is too lazy to come and dawdle, so he volunteered to join the video analysis team. He was about to lose his mind, but he was very familiar with every video in his hands, so when he received Wei Qichen's untold number of calls today, Chen Lin could find exactly what he needed right away.

One and a half hours after the incident, Auntie Cleaning took the elevator with her schoolbag on her back and was sent out of the AC building by another police girl. The video is very short, only 2 minutes, but this woman is facing her back The moment he entered the elevator, Wei Qichen quickly stopped the video.

He Yanzhao pointed at the screen in surprise and shouted, "It's a leather backpack."

Wei Qichen turned his head.

He Yanzhao immediately explained, "The leather backpack is very well sealed, unlike the cloth schoolbag, even if she puts blood-stained clothes into the schoolbag, she doesn't have to worry about the backlog of blood seeping through the surface of the schoolbag, and even if the schoolbag's surface is damaged When the blood is splashed, just wipe the surface with a paper towel or cloth strip, and you don’t have to worry about the blood stains remaining on your back or rubbing on your clothes.”

The author has something to say: To be honest, I want to solve this case more urgently than Team Wei and Xiao He.
