After receiving the alarm, the public security of the police station in the jurisdiction quickly dispatched the police, learned about the situation and felt that it might not be a suicide, so they reported it to the Municipal Public Security Bureau, and soon the Public Security Bureau sent the public security of the criminal investigation team to take over.

Captain Ye of the criminal investigation team came over with two public security officers and a forensic doctor, and the scene had been isolated by the police of the police station, and there were many onlookers outside.

Captain Ye walked over and lifted the white cloth that was covering, "Is your identity confirmed?" ”

"Not yet, I heard that it's not from this community, she is renting a house." Said the person from the police station.

"Which unit is she renting? Call her landlord over. Captain Ye said.

"Yes!" The police officer at the police station responded.

The forensic doctor came to investigate, "the preliminary judgment is that it is a fatal head injury caused by a fall from a high altitude......"

The forensic doctor looked at it with a flashlight and saw the strangulation marks on Cheng Juan's neck, "It shouldn't be suicide, it was he who killed ......."

"Is the landlord coming? Go upstairs and have a look. Captain Ye said.

Soon the landlord received the news and rushed over, and was shocked to hear that the person renting his house had died, how could this happen? That's miserable, will anyone want your house in the future?

"Is this your tenant?" Captain Ye pointed to Cheng Juan who was lying on the ground.

The landlord looked underground and saw Cheng Juan's gray face and a large pool of blood on the back of his head, and his face turned white with fright, "Yes, it's ......"

"Who is she?" Captain Ye asked.

"I don't know, she said she came to her after seeing a small advertisement I posted outside, saying that she used to be a nurse, and she was recently divorced and had nowhere to live and wanted to rent a house, so I rented the house to her." The landlord said.

"Signed a contract? Do you have proof of identity? Captain Ye asked.

"Yes, yes. I brought. The landlord hurriedly said and took out the contract.

"Let's go upstairs and have a look." Captain Ye said, "Is she alone here, or is there someone else?" ”

"When I rented it, I said that she lived alone, and I don't know if anyone moved in later." The landlord replied.

When he arrived on the sixth floor, Captain Ye pushed the door, but he couldn't open it, it should have been locked, "Is there a spare key?" ”

"Yes." The landlord hurriedly took out the key to open the door, but Captain Ye stopped him, "You wait outside, don't come in." ”

"Yes, yes!" The landlord hurriedly answered.

Captain Ye led two police officers into the house, one of whom was responsible for taking pictures and the other was responsible for collecting evidence.

After a while, the public security officer in charge of collecting evidence said: "Team Ye, it's strange that there is not a single fingerprint in this room. ”

"Huh?" Captain Ye frowned, no matter if there is one person or several people living here, how can there be no fingerprints, as long as someone lives, there will definitely be fingerprints.

"It's like someone cleaned it up." The police officer who collected the evidence said.

"Does that mean that the murderer is still there? If something goes wrong, destroy all the evidence right away? Another police officer said.

"Quite possibly!" Captain Ye nodded, searched around, and found traces of a fight on the balcony, and there was a broom on the ground, which should have been ignored by the murderer.

"Take a look at this." Captain Ye pointed to the broom.

"Yes!" The forensic police took the broom into the living room, where the lights were brighter, and then took out the brush to take fingerprints and swept the powder, and sure enough, several sets of fingerprints were found.

"There it is!" The public security officer shouted excitedly.

However, Captain Ye is not optimistic, if the murderer has no criminal record, even if there are fingerprints, it is impossible to find out who it is, and now the public security system has just introduced the computer, and the database is basically empty, and there are few people's information, and some of them are also current criminals.

That night, Captain Ye led people around to inquire, and later learned that someone had seen this woman and brought a man back to live.

There are also neighbors next door who also reported that before the accident, an old man in his fifties asked him to hand over an envelope to the deceased, but he didn't know what it was.

Captain Ye led people to check again in the house, but they didn't find anything, only the deceased's clothes and other daily necessities, as well as a few thousand yuan.

Since the money was not taken, it was not a burglary, and in general, the first consideration was either love murder or vendetta.

I also found a lot of useful clues overnight, Captain Ye and they will close the team first and continue to investigate tomorrow.

Lu Yuanping's heart was still beating when he returned home, when he thought of Cheng Juan's miserable white face, his heart panicked, although she didn't kill herself, but she died because of herself, if she didn't send those photos, wouldn't she die?

He regretted it a little, he didn't expect this to happen at all, he didn't expect them to fight so badly, he thought that the most he could do was to quarrel and then part ways, he didn't expect it to be to death.

That's not what he wants.

He has been a doctor all his life, although he is not responsible for saving people, but he has also saved many people, and he has never thought about who he wants to die.

What to do? Do you want to report the crime?

But what if the police suspect that they did it?

He wasn't sure if Cheng Juan jumped off in anger for a while, or was thrown down by Chen Dongsheng, and he didn't think Chen Dongsheng was yet, right? No matter how noisy you are, you can't throw people down?

Or is it accidental?

But this is all because of myself, so do I have any responsibility?

Lu Yuanping was frightened all night, and he didn't know whether to report the case.

The next day, Captain Ye and the others found Cheng Juan's house according to the identification certificate provided by the landlord, and asked Cheng Juan's mother to go over to identify the body.

Cheng Juan's mother didn't believe it when she received the call, she must have made a mistake, right? How could her daughter die, she has been living well.

Although she was divorced, she didn't say anything bad, she seemed to be living a good life, so she shouldn't worry.

Cheng Juan's mother went to the morgue of the Public Security Bureau to identify, and as soon as she saw Cheng Juan's body, she fainted in front of her.

When I woke up, I was already in the hospital, and I cried bitterly when I thought that my daughter was dead.

"Comrade, what the hell is going on? How could my daughter die when she was so good? How did she die? Cheng Juan's mother asked with tears in her eyes.

"The preliminary judgment is that she fell from a height - that is, fell from a tall building and fell to her death, do you know if she has any enemies, or what strange things have happened to her recently?" Captain Ye asked.

Cheng Juan's mother told what happened a while ago, the relationship between Cheng Juan and Lu Yuanping, and Lu Xiaobei's car accident blood transfusion found out that he was not Lu Yuanping's son, the two divorced, but Lu Xiaobei is Chen Dongsheng's son.

As for whether Cheng Juan was with Chen Dongsheng during this time, she didn't know, Cheng Juan didn't tell her, after all, it was a disgraceful thing, but she suspected that they should be together, but she didn't ask, giving her daughter a little face.

With these clues, Captain Ye decided to talk to Cheng Juan's ex-husband Lu Yuanping and her son's biological father, Chen Dongsheng.

When I returned to the criminal investigation team, I heard from my subordinates that someone had come to report the case, saying that it was related to Cheng Juan's case.

"Who is it?" Captain Ye asked.

"He said his name is Lu Yuanping and he is Cheng Juan's ex-husband!" The subordinate said.
