While Lin Yao and the others were pondering, the victim's husband walked in.

"Comrade policeman!"

When he came in, he was very emotional and shouted at them.

"Comrade policeman, I don't dare to look at my wife's body now, after seeing it, I feel a pain in my heart!"

"If the murderer is caught, I will definitely break his body into pieces!"

Fan Jun got up and walked towards him:

"Don't get excited, then let's go out and talk, I'll ask you a few questions."

"Good! You ask! ”

The man nodded repeatedly.

Then, Lin Yao and the others followed him to the living room.

"What's your name?"

"He Jun."

"What time did you come back?"

Fan Jun stared directly at him and asked.

"It must be early in 10 o'clock, I went out for a drink with my friends after work today, and when I came back, I saw my wife....."

As he spoke, he hid his face again and began to weep bitterly.

"Don't cry first, answer the question first!"

Fan Jun stared at him and said.

"Okay, okay, comrade policeman, I'm sorry, I'm so stabbed that I can't control my emotions."

The man nodded as he wiped his tears.

"Did you contact your wife halfway through?"

Immediately after, Fan Jun continued to ask.

"There is no contact, because I told her during the day today that I will eat out."

"When you come back, is the door lock normal?"

"It's normal, I guess the murderer climbed in through the window or knocked on the door, and then took my wife hostage to the bedroom."

The man said immediately.

"Then when you opened the door and came back, did you hear any special movement inside?"

"No, I didn't hear anything when I came back, I just opened the door and walked in, and when I came in, I saw my wife lying here....."

Subsequently, Fan Jun asked the man some basic information, and then arranged for him to go to the hotel first.

"How? Did you find anything? ”

Fan Jun walked up to the technician who was surveying and asked.

"No footprints, fingerprints, etc. of anyone else were found at the scene, and there were no traces of any windows turning in, and there were no signs of struggle at the door of the room."

The technician reported to Fan Jun.

Fan Jun frowned and turned his head to look at Lin Yao:

"Has this murderer handled it so cleanly that there is no trace of it?"

Lin Yao didn't speak, pondered for a while, and then said:

"Team Leader Fan, tomorrow Xiao Cao and I will be in charge of investigating here, and you will go to investigate the director of the electronics factory."

"This time, the murderer is so abnormal, I feel that something is not right."

"Good!"

Fan Jun nodded in agreement.

.............

Early the next morning, Lin Yao and Cao Lin came to He Jun's residence again.

At this time, the body had been carried away, and there were two police officers guarding the door.

After Lin Yao and the others entered, they looked around.

"Brother Yao, when did you say the murderer would kill next?"

Cao Lin followed behind Lin Yao and asked him.

"I'm not a murderer, how do I know. However, judging from the frequency of his work, it shouldn't be too long. ”

Lin Yao said casually as he walked around the room.

"That's right."

Cao Lin nodded, and then said:

"I wonder if this murderer is a psychopath? There is no law to do things, it is completely just to think of a play is a play, just like this time, the style of the eucalyptus has changed greatly. ”

"I feel like he's just going to make it impossible for us to study him."

Lin Yao didn't speak, but continued to look around.

He then opened one of the cupboards in the living room.

He couldn't help but be slightly stunned.

I saw that there were some bottled milk, coffee and other drinks in this cupboard, and that one drink.

Cao Lin also saw the situation inside the cupboard, and he couldn't help but say:

"He still has so many bottles at home, it's too dangerous, and now this drink is a time bomb!"

Lin Yao stared at the drink placed inside, then took out a bottle from it, held it in his hand and looked at it.

"Huh? That's not right...."

Suddenly, Lin Yao frowned, stared at the drink in his hand and said.

"Is there something wrong? That's the drink, yes. ”

Cao Lin couldn't help but say suspiciously.

"Yes, it's the drink, but the cap seems to have been opened."

Lin Yao said as he stared at the gap under the bottle cap.

Then, he twisted it lightly with his hand and unscrewed it directly.

"That's right, it's opened."

As he spoke, Lin Yao unscrewed off the bottle cap, and then looked inside the bottle cap, there was no picture.

Lin Yao put the bottle aside, and then took out another bottle from it.

"This bottle is also unscrewed!"

Lin Yao couldn't help but say in surprise.

Immediately afterwards, he didn't take out all the drinks in it, and then checked them one by one, and found that the caps of these drinks had all been unscrewed, and there were no pictures in the bottle caps.

"This ..... What's going on? ”

Cao Lin couldn't figure it out for a while when he saw this situation.

"We've seen it when we opened bottles in the supermarket before, and the mouths of those drink bottles are sealed, even if there is a picture in the cap, the cap is also sealed."

"Why was all of this he bought opened?"

Lin Yao's eyes narrowed slightly, staring at these drinks tightly, and then, he said in a deep voice:

"So, these drinks should not have been bought by him, but he opened them himself."

"What? He opened it himself? He opened all the caps, and then selected a bottle with a picture on it and drank it, and let the murderer kill him, is he crazy? ”

Cao Lin's eyes widened in shock and said suspiciously.

"No, he didn't let the murderer come and kill him."

Lin Yao shook his head slightly and said.

"You mean ......"

Suddenly, Cao Lin reacted and said in surprise,

"He deliberately let his wife drink this bottle and then let the murderer kill her?"

"Don't bother."

Lin Yao shook his head, then took out his mobile phone and called Wang Ming, who was in charge of the inspection in the technical squadron.

"Hello? Brother Wang, the bottle of drink I got back from the Changhe Community last night, you can help me test the saliva on the mouth of the bottle, compare who it is, and reply to me as soon as possible. Okay, thanks! ”

After finishing speaking, Lin Yao hung up the phone directly.

Then, he turned around and walked straight outside.

Seeing this, Cao Lin hurriedly followed.

"Where to go? Brother Yao. ”

"Do some research on your neighbors."

With that, Lin Yao walked directly downstairs, and then knocked on the door.

"Who?"

A cautious woman's voice came from inside the room.

"Municipal Criminal Police Team."

Half an hour later, the door opened a crack, revealing the face of a middle-aged woman.

When she saw clearly the police uniforms worn by Lin Yao and the two of them, she dared to open the door.

"Comrade policeman, is there anything wrong with you? After that incident upstairs last night, I've been scared all night! ”

The middle-aged woman looked at Lin Yao with a frightened expression and said.

"I'm sorry, we'd like to ask you something."

"Okay, please come in."

Then, the middle-aged woman invited Lin Yao and the two of them in, let them sit on the sofa, and then poured them a glass of water.

"Don't be busy, let's get to know the situation and leave."

"Comrade policeman, did the serial killer come upstairs last night? It's scary! ”

The middle-aged woman clutched her chest and said with a heart.

This kind of thing happened around her, only a wall away from her, and the impact on her psychology was too great.

"The matter hasn't been investigated yet, so don't worry too much."

Lin Yao soothed her, then showed her the photo of the drink and asked her:

"You don't have this drink at home, do you?"

The middle-aged woman leaned in to take a look, and then said directly:

"No, no, we've never drunk this drink before, and now we've been posting notices on the Internet and TV, how dare we buy this drink!"

"It's good if you don't have it."

Lin Yao nodded, and then continued to ask:

"How's your relationship with the house upstairs?"

"I still understand, because we are also an old community, and the neighbors are relatively familiar."

The middle-aged woman thought for a moment, then said.

"Who's in their house upstairs?"

"It's the two of them, and they have a child, but the child goes to school outside and doesn't live at home, so I haven't seen them for a long time."

The middle-aged woman immediately replied.

"How is the relationship between them and the couple?"

"Husband and wife feelings?"

The middle-aged woman hesitated slightly, then said:

"It's hard for us to say anything about things between husband and wife."

"But as far as I know, this man is not good, he raised a junior outside, and he quarreled every day because of this for a while ago, and then I don't know what happened."

"Little Three.....

Lin Yao and the two couldn't help but mutter, and then looked at each other.

They then asked the middle-aged woman some more questions and walked out.

As soon as he walked out of the door, Lin Yao's mobile phone rang again.

"Hello? Brother Wang, you say. What? Found a man's saliva at the mouth of the bottle? Okay, I see, thanks. ”

After finishing speaking, Lin Yao hung up the phone.

"Brother Yao, only men's saliva? That is to say.... This murderer is mistaken? The man drank the drink, but he killed the woman, and it seems that he can only determine which one bought the drink. ”

"I'll just say he can't be so precise about who's drinking!"

After Cao Lin heard this, he couldn't help but immediately say to Lin Yao.

"No.... I'm pretty sure now that it's a hitchhiker! ”

Lin Yao sneered and shook his head directly.

"Hitchhiker killing? You mean.... The murderer is actually the husband of the deceased? ”

Cao Lin's eyes suddenly widened, and he looked at Lin Yao and asked.

"That's right."

Lin Yao and Cao Lin stood in the corridor, Lin Yao took out a cigarette from his pocket and lit it.

"One of the characteristics of hitchhiking is that because the hitchhiker doesn't fully understand the style of the serial killer, there are a lot of things that are a little different."

"For example, this time, whether it is the position of the dagger, the number of knives stabbed, and whether the dagger is left behind, there are some differences from before."

"This is because we did not release the details of the eucalyptus, which led to the de-imitation of the murderer, but not to the extent that it is 100 percent similar."

Cao Lin couldn't help but nod again and again, and then said:

"No wonder no trace of outsiders was found in the room, it turned out that the murderer was himself!"

"Let's go to the property monitoring room."

After finishing speaking, Lin Yao turned around and went downstairs directly.

After explaining the intention to the people in the property in the monitoring room, the surveillance video from last night was retrieved.

After some comparison, they found a tightly wrapped man who first walked into the community at about six o'clock, and then came out of the community at about ten o'clock.

At 10:13, the victim's husband came in from outside the entrance of the compound.

"That's him!"

Lin Yao pointed to the screen and said directly,

"This man who is so tightly wrapped is the husband of the deceased."

Seeing this scene, Lin Yao was even more angry.

Now there is such a big head for this serial murderer, and there are people who join in the fun and hitchhike to kill people, disrupting their detection direction!

Immediately afterwards, Lin Yao analyzed:

"This must be how it happened, this man has a conflict with his wife, and he has the idea of killing her."

"As a result, he happened to see the serial murder in the report, so he wanted to imitate the murderer, he bought a large amount of this drink, and opened the bottle cap just to find the picture, so as to blame it."

"Damn! Now that I think about it, I feel sick when he cried so sadly, pretending to be like it! ”

Cao Lin couldn't help but smash the wall of the corridor and scolded loudly.

"So what do we do next? Find evidence of his crime and arrest this kid? ”

Then Cao Lin looked at Lin Yao again and asked.

"Now that the general situation has been determined, we can just leave this eucalyptus to someone else, and our priority now is to catch the murderer of the serial killer, otherwise more people will be killed."

Lin Yao shook his head slightly and said.

"Yes, yes, now the real bottle cap murderer is the key!"

Cao Lin nodded in agreement.

Lin Yao took out his mobile phone from his pocket and called Fan Jun.

"Hey, Team Leader Fan, I have made an important discovery in the eucalyptus here."

"You say."

"I suspect that this case is a hitchhiker murder, and the real murderer is the husband of the deceased."

Lin Yao said directly to him.

After Fan Jun heard Lin Yao's words, he immediately exclaimed:

"What? Hitchhiker kills eucalyptus, what's going on? ”

Subsequently, Lin Yao told Fan Jun what he had discovered.

With years of experience, Fan Jun also decided that the murderer was the husband of the deceased when he heard this.

"Team Leader Fan, you can arrange for someone else to follow up on this eucalyptus, and I will now go to the director of the electronics factory to investigate."

Then, Lin Yao said to Fan Jun.

"Okay, come here!"

Fan Jun immediately agreed.

Subsequently, the two hung up the phone, and Lin Yao directly called Cao Lin to go to Huafeng Community.

After coming to the eucalyptus scene, Fan Jun was discussing something with Han Bin and the others.
