Liu Yan and Song Tao were eating in the snack street, chatting boringly, they were all inconsequential things, fortunately, they completely solved this homicide case, and let the big stone in everyone's hearts fall.

Song Tao said, "By the way, Liu Yan, by the way, how did you identify the murderer as Zhuang Yan?

How can there be such a superficial guess, it's just that when Liu Yan was looking for the front seat drawer of the deceased Wang Feng's car, she accidentally saw a shameful condom, and the pants of the two deceased's lower bodies were strange, so Liu Yan had this guess, this Zhuang Yan must have a lot to do with the case.

But Liu Yan knew that she knew, but Liu Yan still didn't want to say this kind of shameful thing, and said casually, "Intuition." ”

"So powerful?"

"Uh-huh, that's it. Liu Yan spread her hands and said so arrogantly.

Song Tao smiled and didn't continue to say anything.

After eating the snack, Liu Yan touched her stomach, showed a satisfied smile, and said with a smile, "Song Tao, you're full." ”

Song Tao said, "I'm full, and then what?"

You can't keep letting people break the bank, which makes Liu Yan unhappy, so Liu Yan made a request to go back, "Forget it, let's go back." ”

"So early?"

Liu Yan stretched and yawned, "Go back, you can finally relax." ”

Song Tao smiled, "Yes, you can relax." ”

In fact, Liu Yan didn't know that the current case of serial murder was the first time that Song Tao encountered it in the jurisdiction, and its seriousness can be imagined.

Song Tao stood up, "It's okay to go back, go back." ”

Liu Yan then stood up, followed Song Tao out of her seat, and got into the police car;

In the next four days, Liu Yan lived a peaceful and leisure life, and the fly in the ointment was that Anya forced Liu Yan to find a job;

But four days later, a new case appeared: at 9:23, Liu Yan was driving a battery car, wandering outside, when suddenly the phone rang.

Liu Yan slowed down the car, leaned towards the side of the road, and after parking, she took out her mobile phone to see that it was Song Tao;

was really hit by Liu Yan's crow's mouth, the voice on the phone was a little anxious, and Song Tao said, "That's right, where are you? The case happened in your community." ”

Liu Yan frowned, "In our community?"

"Yes, 601 from Unit 6, come over right away. ”

Liu Yan nodded, "I'm outside, I'll go over now." ”

"Uh-huh. ”

Liu Yan didn't reply, so she hung up the phone, put her phone away, and planned to go back to the community to have a look, muttering the address that Song Tao had reported to herself just now, "Unit 6, 601." ”

After entering the community, Liu Yan parked the car at the carport, and then went directly to the location that Song Tao said, that is, the sixth unit; when she arrived at the door, she took the elevator and pressed the button on the sixth floor directly.

The elevator door opened, Liu Yan saw the door at once, crowded with many people, Liu Yan frowned, this full of people crowded, how can you squeeze in?

There was really no way, Liu Yan shouted, "Let one go, let one go, that's my relative." ”

Don't say it, as soon as others heard this, they really mistakenly thought that Liu Yan was really a relative of the deceased, and sympathetically let go of a narrow passage.

When she walked to the door, Liu Yan saw that there was a cordon there, but Liu Yan didn't care, she didn't bother to call Song Tao, so she praised it directly.

Ding Jia, who was guarding the door, recognized Liu Yan, so naturally he wouldn't stop him, and said politely, "Sister-in-law, you're here." ”

Liu Yan glanced back, she didn't pay much attention just now, and then she saw it, "It turned out to be Ding Jia, Song Tao is inside, right?"

"Uh-huh, in there. Ding Jia hurriedly said.

Since this is the case, Liu Yan walked in, saw that there was no one in the living room, and looked at the room next to her, and happened to be in a room, and saw Song Tao and Zhang Qian.

Liu Yan walked in and said hello, "I'm here." Liu Yan added, "You two, what are you doing?"

Zhang Qian turned his head and smiled, "Sister-in-law, you're here." ”

Isn't this nonsense, everyone is here, isn't it here, can you still go?" Liu Yan didn't bother to take care of it, and asked instead, "Let's talk about it first, what's going on." Then his eyes turned to a man and a woman on the bed.

The man and woman on the bed are still young, that is, about twenty-five, but the eyes of both of them are closed, and Liu Yan's heart "chuckles", isn't it that both of them are dead?

Song Tao began to explain the matter, "That's the case, we received the alarm and came over immediately, and when we opened the door, it was already the case." ”

Liu Yan sniffed it with her nose, sniffed it, and always felt a strange smell, and asked, "What kind of smell is this?"

"Carbon monoxide also smells like carbon dioxide. After speaking, Song Tao pointed to a rather large stove under the bed.

At first, Liu Yan really didn't notice it, but when she saw it, she instantly understood what the whole thing had happened; Liu Yan whispered, "Suicide?"

Song Tao shook his head, "Yes, but it's not." ”

What kind of strange answer is this? Liu Yan asked, "Why do you say that?"

Song Tao took out a transparent plastic bag, and there was a piece of paper in the plastic bag, and the handwriting on the paper was very neat.

Liu Yan took the plastic bag and began to check the contents of the paper; the general content is that there were some problems in the relationship between the two, and the man had a bad idea, threw sleeping pills, and the medicine poured the woman, and finally the man also had no memory of the world, found a fire, closed all doors and windows, and finally stepped up to the Yellow Spring.

Seeing this, Liu Yan frowned, "The words on this paper were written by a man?"

It's really hard to say, Song Tao said, "If it's suicide, then it should be." ”

Liu Yan blinked, "Why do you ask that?"

"The door outside has signs of being pried open, so I called you over. ”

So that's the case, Liu Yan ignored the two dead people in front of her for the time being, walked out, and confirmed that the keyhole of the outer door was indeed a trace of being pried open.

After checking these, Liu Yan began to conduct a comprehensive investigation of the room, and it was really as said on paper, the entire room, the whole home, was sealed and blocked, and even some small vents were blocked by wet towels.

Liu Yan frowned, the cause of death was known, but Song Tao suddenly said that he might suspect that he killed him, which made Liu Yan guess.

It stands to reason that this case is not difficult, but being suddenly bluffed by Song Tao really made Liu Yan difficult to start, so she walked back to the deceased's room and looked at the two corpses;

Liu Yan stood up straight and said, "Song Tao, please have a forensic doctor." "For the internal problem, Liu Yan is really helpless, "Check whether the man also has sleeping pills in his body, if there are really any, then it is possible that he killed him, after all, the man has no external injuries, and the chance of unexplained coma is too small, and the poisoning time of carbon monoxide and carbon dioxide is very long." ”

felt that Liu Yan's words made sense, so Song Tao did so, "Okay, I'll contact the forensic doctor." ”

Before the forensic doctor came, Liu Yan began to test the two corpses, and it was initially estimated that the two died of hypoxic poisoning, but if it was really he who killed him, the man who was not harmed should have taken a large amount of sleeping pills.

Liu Yan suddenly said, "By the way, Song Tao, where are the sleeping pills?"

"We didn't have to look for it, we found it in the first place. After finishing speaking, Song Tao shouted, "Zhang Qian, didn't you put away the sleeping pills?"

After a while, Zhang Qian's fart came over, holding a transparent plastic bag in his hand, and there was a bottle of medicine in the bag.

However, Liu Yan was still curious, and said to Song Tao, "Song Tao, disposable gloves, I want to open the bottle of sleeping pills to see." ”

Since this is the case, then let Liu Yan take a look, maybe she can really see what is coming.

After taking the disposable gloves handed over by Song Tao, Liu Yan reached out and took out the sleeping pills in the transparent plastic bag, weighed them, and gave people a lot of feelings.

Out of curiosity, Liu Yan opened the bottle, first sniffed it, and then estimated the amount of medicine inside;

Liu Yan frowned, relying on these doses, can they really take down two people and let them die of lack of oxygen in a coma?

Although she realized this, Liu Yan didn't plan to say it, and when the forensic doctor really came, then all the problems would be solved, and this was the evidence that Song Tao wanted.

Unconsciously, Liu Yan began to speculate, these things looked like suicide, and Song Tao suddenly said that he killed, what was going on?

Liu Yan, who really couldn't figure it out, walked out alone, and when Song Tao saw this, he shouted, "Liu Yan, where are you going?"

Only then did Liu Yan realize that she was still holding sleeping pills, put them in a transparent plastic bag, and then handed them to Song Tao, "I'll go somewhere else to see, maybe I can get something." ”

Since this is the case, Song Tao couldn't say anything, and took the sleeping pills, "Go, go." ”

Walking out of the door of the deceased's room, Liu Yan touched her chin, and always felt that something was missing, a strange thing.

Then Liu Yan scratched her head and said to herself, "Damn, there's something missing." ”
