Could the perpetrator have climbed up from the back wall?

Liu Yan suddenly had such a thought in his heart, he muttered a few words to Lian Jianfeng, and then led a few policemen to the back wall of the community.

Outside the back wall of the Fuguiyuan community, there is the backyard of an express hotel, in which dozens of cars are parked, brightly lit, and there is a security guard, who is patrolling back and forth.

Liu Yan walked up to the security guard and asked, "Comrade, have you been on duty here tonight?" ”

The security guard looked at Liu Yan, and then at the several policemen standing behind Liu Yan, and said a little nervously: "I won't tell you, I only came to the backyard to patrol in the middle of the night, and there are no security guards here at all. ”

Liu Yan asked again: "Is there a camera installed in this place?" ”

The security guard shook his head and said, "No, this is just a place to park vehicles for guests staying in the hotel, and the front lobby is connected, and after eleven o'clock in the evening, the door leading to here from the outside is locked, even if there is any movement, the staff on duty in the lobby can hear it, there is no need to install that thing." ”

Liu Yan asked again: "Who is on duty in the lobby in the first half of the night tonight?" ”

The security guard said, "It's Sister Qin, she's still on duty now, or I'll take you to see her?" ”

Liu Yan responded: "Okay, you take us to meet her." ”

The security guard led Liu Yan and his party to the front desk of the Express Hotel.

The woman on duty was about thirty years old, with a confused look, as if she had just woken up, when Liu Yan asked if there was any unusual movement in the backyard of the hotel in the first half of the night, Ms. Qin shook her head and said: "I didn't pay attention, there were a lot of parking in the backyard in the first half of the night, and there would be movement from time to time, if you want to say that there was any abnormal movement, I really don't know." ”

Liu Yan was a little disappointed in his heart, and felt that what Ms. Qin said was the truth, before eleven o'clock in the evening, it was the peak period for guests to check in to the hotel, and people and cars came and went, even if there was any movement, everyone would not particularly care.

When he was in the backyard just now, Liu Yan had already made observations, although the backyard was brightly lit, the visibility was still much worse than during the day. He had just taken a closer look at the back wall of the community, and there was no sign of climbing upwards, perhaps because the visibility was too low.

Liu Yan raised his wrist and looked at his watch, it was already five twenty o'clock in the morning, at this time, it should be the darkest time, Liu Yan instructed the security guard of the hotel to let him go to the backyard and always pay attention to suspicious movements, and then said hello to Ms. Qin, and asked the police to rest temporarily in the lobby of the hotel for a while, tossing for a whole night, he was also a little tired.

Just after a little stunned, just after six o'clock, Liu Yan woke up, at this time the sky was completely bright, Liu Yan woke up Lian Jianfeng and several other policemen, and everyone walked towards the backyard together.

In the early summer morning, the light is very good, although the sun has just emerged, but the surrounding objects are clearly recognizable, three or four meters away from the back wall of the community, Liu Yan saw that there are indeed traces of climbing on the wall.

This trace appeared in the two places of the rear window and the sewer pipe of the second unit, the climber's arm was obviously grasping the iron hoops of the upper hoop of the sewer pipe to go up, but his feet stepped on the window sill about five or six centimeters away from the sewer pipe, from the iron hoop that fell on the sewer pipe and the traces on the window sill, the climber's hands and feet were wearing covers, which may be plastic or cloth, because the feet were very hard in the process of climbing, and the marks left on the floating ash on the window sill were obvious.

According to the part of the two feet, Lian Jianfeng judged that the climber's height was about 1.78 to 1.81 meters, and the shoe size was 43, he jumped directly into the room from the window sill on the fourth floor, and the lock between the two windows was not pried, which shows that this window is likely to be deliberately opened by the owner of the house, and it has not been closed until now.

Liu Yan judged that the reason why the climber climbed into the room from the windowsill so hard was obviously because he didn't want the community's surveillance to film him, and for Jiang Limin, it was very likely that the two of them were having a tryst. If there is no such relationship between the climber and Jiang Limin, then the unexpected arrival of the climber will inevitably cause Jiang Limin to be highly vigilant, she will shout and struggle, so that it is impossible to cause the evil consequences of falling from the building.

Since the two of them were in a tryst, and it took so much effort to climb into the room, they had to do something, right? When Jiang Limin's body was sent to the hospital, Liu Yan specially instructed that he should focus on checking the situation in this regard.

At about eight o'clock in the morning, the results of the hospital examination came out, and there was no such residue in Jiang Limin's body.

Although Liu Yan was a little disappointed by this result, he was even more convinced that this climber had made full preparations when he came to Jiang Limin last night, and his ultimate purpose was to create a false impression that Jiang Limin had committed suicide by falling from the building.

So, he didn't want to leave anything of his own at the scene of the incident.

Liu Yan did not give up, and once again came to Jiang Limin's residence, carefully inspected every corner of the bed, and finally found a very short hair on the sheet, this hair was about two centimeters long, obviously left by the man, whether it was the hair of the person last night, it is still uncertain.

This hair is the only clue so far, and Liu Yan handed it over to a police officer and asked him to take it to the hospital for further identification.

After doing this, Liu Yan sat alone in Jiang Limin's room, thinking quietly.

What kind of character will this man be? Intuition told him that this man should have a family, and if both of them are not married, then they can have a fair and bright relationship, and there is no need to climb the wall at all.

Since the relationship between the two has developed to the point of a private tryst, then, in daily life, Jiang Limin should have frequent contact with this man, so that they have a good impression of each other.

So, in daily life, which men will have the opportunity to have frequent contact with Jiang Limin?

The first category should be the people in her life circle, this life circle, including the residents of the Fuguiyuan community where she lives, and also the part of the people that her living habits can often come into contact with, such as card friends, drinking friends, travel friends, and so on.

According to the residents here, Jiang Limin has always gone straight to work and never greeted anyone in the community, and it is impossible to have a story with a man in the community in a situation like this.

The rest are the card friends, drinking friends, and travel friends she has met in her living habits, if you want to understand these, you must first know what special living habits Jiang Limin has.

The second type of people should be people in her work circle, in her work circle, there are also two kinds of people who have more frequent contact with her, one is her colleagues at work, and the other is the enterprise managers who often deal with the power management station.

The third type of people are the people in Jiang Limin's social circle, including the card friends, drinking friends, and travel friends she has met, as well as the leaders and colleagues who have a certain relationship with her at work, in addition, as well as friends derived from her social relationships, and friends of friends.

In order to understand these, we must first understand Jiang Limin's living habits, Liu Yan is ready to start from three aspects, the first step is to understand the residents of Fuguiyuan Community, the second step is to understand Jiang Limin's relatives, and the third step is to understand Jiang Limin's colleagues.

When Liu Yan came down from the upper floor, Lao Du, the property manager of the community, was sticking out his head to look at the south building. The Fuguiyuan community is not large, with only more than 70 residents, so all the property management work, including cleaning, security work, and collection of water and electricity bills, is all done by Lao Du alone.

Judging from Lao Du's expression, he should be a person who likes to inquire.

Sure enough, before Liu Yan walked in front of Lao Du, Lao Du spoke: "Mayor Liu, is the case closed?" Is it suicide or homicide? ”

Liu Yan shook his head and said, "It's not over yet, Lao Du, there is a situation I want to ask you, has Jiang Limin brought strange men to the house recently?" ”

Lao Du said: "No, not to mention that recently, since she lived in this community, she has never brought a stranger back." Jiang Limin is a person who doesn't like to socialize, and her daily life is two o'clock and one line, going to work at seven o'clock in the morning and coming back at six o'clock in the afternoon. Even her relatives have not been here for at least a year, it is said that it is because when she divorced, she was burdened with a debt of more than 2 million, which made her relatives very dissatisfied with her, so they cut off contact. ”

Lao Du's words made Liu Yan feel that Jiang Limin was a pure-hearted person with few desires, and had no hobbies such as playing cards, drinking, and traveling at all.

However, Liu Yan is still ready to continue to further understand Jiang Limin from another side, some people, the performance at home and in the unit is completely like two people, at home is a stuffy gourd, but in the unit is a very active role.

Originally, Liu Yan was going to ask Jiang Limin's relatives about her situation in the next step, but just now I heard Lao Du say that she had not been in contact with her relatives for more than a year, and Liu Yan simply dispelled this idea.

Then, the focus of the next step can only be understood from Jiang Limin's unit investigation.

As soon as Liu Yan walked out of the gate of the Fuguiyuan community, his mobile phone suddenly rang, it was a call from the hospital, and Dean Zhang told Liu Yan that the test of that hair had already yielded results.

This result can't help but make Liu Yan laugh.
