After the site survey,

Zhou Zhengcheng took Zuo Xu and began an on-site investigation, preparing to learn about the basic situation of the victim from the neighborhood.

"Hello, auntie, we are from the homicide department, we want to know about the situation of 505 with you, do you know Dong Hongbin?"

Zhou Zhengcheng knocked on the door of 504 next door, and a lady came out of it, she saw Zuo Xu and them, and her eyes showed a trace of fear!

After all, the neighbors who get along day and night met yesterday and greeted each other vigorously, but today they were killed, and even their heads were cut off.

Such a heartbreak is really terrifying!

"Alas, what a good family, they are polite when they meet, it feels like a dream, I can't believe it, they are dead!"

The eldest lady sighed, a little difficult to accept the reality: "Usually Sister Ma and I often dance square dances, she often praises his son in the Water Power Department, how useful he is, and how sensible and filial his daughter-in-law is, but I didn't expect that in a blink of an eye, people are gone!" ”

"Auntie, during this time, have you seen or heard anything unusual in their house, or any suspicious people who often come to their house?"

Zhou Zhengcheng interrupted the aunt's sigh and began to ask the other party in a guided way.

"I haven't noticed, there are very few guests in their house, but Dong Hongbin has a lot of entertainment, and I have seen him come back drunk several times."

"Think about it carefully, have any relatives or friends come to their house in the past two days?"

Zhou Zhengcheng continued to ask questions without giving up, the reason why he asked this was for a purpose.

Although the crime scene they investigated today was destroyed twice, it was not completely without gains.

The scene of the crime was on the 5th floor, and they checked the windows of all the rooms, as well as the balconies outside, and found no signs of climbing.

The killer apparently came in through the entrance door.

However, there is no trace of the lock on the entrance door being violently unlocked.

So he boldly guessed that the murderer was very likely to have a key to the entrance door.

Who has access to their home key?

The answer is simple, it must be someone they trust more!

The person who was trusted, killed the whole family.

Although this speculation is somewhat difficult to accept, it is not impossible.

So the first thing they have to do is rule it out.

Hearing Zhou Zhengcheng's question, the eldest lady frowned and thought about it carefully: "When I usually chatted with Sister Ma, I heard her say that since her wife died of illness, their relatives on this side have not interacted much, and during the Chinese New Year, they didn't see how their family went to relatives. ”

Then Zhou Zhengcheng asked a few more questions, but when he couldn't find anything valuable, he ended the conversation.

Next, I found a few neighbors and made a few records, but the content was also the same.

And no valuable clues were found!

Seeing that the sky was about to get dark, they had no choice but to send the physical evidence collected today to various departments before the Public Security Bureau got off work.

"Let's work extra tonight!"

Not surprisingly, Wen Ce's first sentence was to let everyone work overtime tonight.

Zhou Zhengcheng has long been accustomed to it, only Zuo Xu, this is the first time!

But definitely not the last!

Back at the Public Security Bureau, Zhou Zhengcheng instructed Zuo Xu to send the physical evidence to various departments in different categories, summarize and summarize them, and extract valuable clues as soon as possible, so as to point out the direction for them to solve the case.

He himself went to the intelligence department and began to understand the family situation of Dong Hongbin's family and social relations in an all-round way!

After Team Leader Wen came back, he was not idle.

With such a big case, he immediately ran to the leader to report the latest progress of their investigation today!

If you don't get it right, you may have to make a military order and solve the case within a time limit.

Zuo Xu's work is in the nature of running errands, and he is the first to complete and the first to return to the office.

At this time, it happened that the other colleagues of the Public Security Department had reached the end of work and walked out of the door one after another.

Wen Ce just explained, he is working overtime tonight, and he can't leave yet.

I made a phone call to my mother and told her that she was working overtime tonight and would not go back to eat, and asked her to eat by herself and not wait for herself.

Then Zuo Xu ordered three boxed lunches and asked the other party to send them to the Public Security Bureau.

When people are busy, they really forget to eat.

So while there is nothing to do now, Zuo Xu will prepare first!

After a while, Wen Ce came back, and when he saw that Zuo Xu was the only one in the office, he asked, "Xiao Zhou hasn't come back yet?" ”

"Yes, he went to the intelligence department and hasn't come back yet."

Wen Ce nodded: "When he comes back, let's have a meeting." ”

After sitting down, I picked up my pen and notebook, and wrote down the issues to be discussed in the meeting for a while.

"Okay."

Zuo Xu answered, picked up the pen, and recorded the situation of his investigation today.

It's just that today's case has brought him a lot of discomfort physically, and for a whole day, his mind was full of headless corpses, and Qian Lao held his head and commented on it.

Since joining the Homicide Division, he has been scared twice in a row.

The evil spirit made him experience psychological fear, and the headless corpse made him physically sick.

At school, though, you will also see photos of some special cases.

But one is a photo, which gives the impression that it is separated by a world.

Sitting in front of the TV and watching zombie movies, and cutting zombies in person, are really two experiences.

The bloody scene you saw at the scene of the murder, coupled with the smell of blood coming from the tip of your nose, and the stimulation of multiple senses, are definitely not what the photos can give you.

"Little Zuo?"

He was thinking about things when he suddenly heard Wen Ce calling him, and hurriedly put down his pen and said, "Here." ”

"Are you still comfortable with today's case?"

"Adapt."

Can't say it's not adaptable!

"Join the homicide department, this kind of case may be the norm in the future, you have to be mentally prepared!"

"Yes, thank you Team Leader Wen for your concern!"

"What do you think of today's case?"

Wen Ce's sentence already has the meaning of taking the school entrance examination.

Although Zhou Zhengcheng praised Zuo Xu as a flower in front of him, hearing is false, and seeing is believing.

Zuo Xu is not a fool, so he naturally understands what Team Leader Wen means by asking this sentence.

Although he didn't use advanced survey skills today, it wasn't completely without benefits!

He followed Zhou Zhengcheng today and learned a lot.

Especially for such a big case, he feels that if he comes back a few times, his primary investigation skills can be upgraded to the intermediate level.

So he reported what Zhou Zhengcheng taught him today, combined with his own speculation, and Wen Ce:

"Through the investigation of the crime scene, the murderer should not be for money, although we do not know the financial situation of the victim's family, but the two thousand yuan in the bedside table have not been touched.

is so conspicuous, as long as you pull the drawer, you can see it, but the murderer did not move, there was no action to loot the finances at all, obviously he was not for money. ”
