Gu Chen and Qi Tian looked at each other, as if they both wanted to go together.

"Is Boss Meng's son called Meng Yang?" Gu Chen asked.

The woman was stunned for a moment, and said, "How do you know? That's right, Boss Meng's son is called Meng Yang." ”

"Does he still have a habit of collecting sneakers?" Qi Tian also asked.

"Yes, he has a lot of shoes in his room, and he asked me not to move, I heard that they are quite expensive. The woman also recalled for a few seconds, and then said: "But I don't understand much, so I usually don't clean the boss's son's room, and even if I have to clean it, I have to do it under his supervision." ”

"You said that only Meng Yang had been here in the afternoon, but did you leave at that time?" Gu Chen picked up the transcript and asked again.

In fact, if this condition is true, then Meng Yang and the woman who reported the crime are both suspicious, because no one else has been to the scene.

The woman nodded and said, "Yes, around three o'clock in the afternoon, after Meng Yang came here, I left." ”

"But why are you leaving? is it because Meng Yang has something to discuss with Boss Meng?" Gu Chen asked.

"That's right. The woman did not deny it, and said: "Meng Yang seems to have come to ask Boss Meng for money, he seems to be short of money recently, but the two quarreled." ”

But because I was an outsider and it was embarrassing to stay at home, I said hello to Boss Meng and told him that I would come back at night to clean the rest of the room. ”

"But before I left, Boss Meng and Meng Yang were still arguing, and both of them seemed to have a big temper. ”

The scene suddenly fell into a brief silence, and judging from various conditions, Meng Yang seemed to be the most suspicious.

But whether this middle-aged woman is lying or not, it is unknown at present.

Gu Chen carefully observed the layout in the room.

The Meng family lives in a small western-style building, and the monitoring layout is set up at the four corners outside the door.

It can be said that if you want to enter and exit Meng's house, the surveillance will definitely be able to photograph it.

"Where is the monitoring and operation platform of the villa?" Gu Chen walked to the door, turned around and asked the woman who called the police.

"You mean...... "The woman doesn't know much about this, but she also knows that she can see the monitoring from the computer screen.

"That's right, this is it. Qi Tian on the side echoed.

"In the next room to the boss, or I'll show you there. The woman understood now and hurriedly said.

The others didn't dare to slack off, and the police officer just now stayed outside the scene, and Gu Chen and Qi Tian followed the woman to the next room.

The woman didn't understand it very well, but Gu Chen was very proficient in this kind of operation, and she called up the surveillance screen at about three o'clock in the afternoon by dividing five by two.

In the picture, Meng Yang, who had a verbal altercation with the elderly in Huimin Supermarket in the afternoon, drove to the front of the villa, and then walked into the house.

Time is advancing minute by minute......

About fifteen minutes later, the woman who called the police left the villa with a satchel on her back.

More than an hour passed before Meng Yang walked out of the house dejectedly.

But instead of driving, he left on foot......

Gu Chen sped up the surveillance screen again and advanced it until the alarm woman walked into the villa.

It didn't take long for Gu Chen and Qi Tian to arrive at the scene.

"That's right, Meng Yang was indeed the last to leave the scene, and this Boss Meng has obviously been dead for a while. Gu Chen made an approximate inference about the time of death based on the characteristics and characteristics identified by Forensic Liu in the past.

"You're right. Qi Tian also confirmed: "From the time she entered the room to the time we arrived at the scene, the time was very short, but Boss Meng has obviously been dead for a while, so her suspicion can be ruled out for the time being." ”

Seeing that the police cleared her suspicion, the woman immediately breathed a sigh of relief, patted her chest and said gratefully: "Thank you police comrades, thank you very much, I thought I would make a big deal, I was really afraid that you would misunderstand, and then arrest me at the police station." ”

"We don't wronged a good person, and we don't let a bad person go. Gu Chen saw that the woman was nervous, and comforted her: "You did a good job of protecting the scene, after you found the problem, you notified the police in time, and did not leave the scene without authorization, you did the right thing." ”

"Yes, ordinary people have already scared away, it seems that your psychological quality is still excellent. Qi Tian couldn't help but praise a few words.

The woman said embarrassedly: "Comrade policeman, don't tease me, I'm just afraid of being implicated, now my suspicion can be ruled out, then please find the murderer immediately and bring him to justice." ”

Hearing Gu Chen's words just now, the middle-aged woman didn't think much about it, but she didn't feel so nervous anymore when she looked at the appearance of the police.

She was originally a part-time worker, but now that her boss is gone, she doesn't know who to settle her salary with, so she is still a little frustrated.

Moreover, the boss who was fine in the afternoon, why was it gone in the evening, she always felt that it was too strange.

Gu Chen's expression didn't change much, he continued to put on his white gloves and said to Qi Tian beside him: "Senior Brother Qi, let's check the scene again." ”

"Inspect the scene?" Qi Tian, who was thinking about how to arrest people later, couldn't help but wonder: "Isn't it right to go and arrest Meng Yang directly?"

"But Meng Yang is the deceased's own son after all. "Gu Chen Anyway, judging from his contact with Meng Yang, although this guy is sometimes excessive, judging from the actions of only one dollar, he is still kind in his heart.

Therefore, even if all the evidence pointed to Meng Yang, Gu Chen still hoped to find better clues.

"That's okay, you stay and continue the search, and I'll go with someone to find Meng Yang. Qi Tian was also anxious, and felt that this major suspect should be arrested as soon as possible.

After communicating with the police officer at the door, the two drove away.

At this time, there was still an old comrade in the room, and he continued to search for suspicious clues at the scene.

"Senior brother, did you find anything just now?" Gu Chen couldn't help but ask curiously when he saw the other party coming over.

"I found two drinking glasses in the room. After thinking for a few seconds, the old comrade said again: "Maybe after they drank it, they haven't had time to clean it." ”

Gu Chen didn't say much, walked directly into the room, and sure enough, as the old comrade said, the two used wine glasses are still on the desk.

And on the closet of Boss Meng's room, there are many imported wines.

Red wine, white wine, beer, you name it.

If Meng Yang is obsessed with the sneaker circle, then Lao Meng should be obsessed with collecting good wine.

It can be said that both father and son have their own interests and hobbies.

Gu Chen walked back to Boss Meng's body, turned on the strong flashlight, and examined Boss Meng's mouth.

As the woman who reported the case said, he did have symptoms of inflammation of his gums.

Half an hour later......

Qi Tian and another old comrade returned triumphantly and brought Meng Yang directly into the scene.

"Where's my dad, where is he?" Meng Yang also seemed shocked by the news of his father's death.

When he found his father lying on the ground, he was stunned, and immediately rushed forward with a scream, as if to hug his father's corpse.

"Dad, what's wrong with you, what's wrong with you?" Meng Yang shouted loudly, and the whole person was hysterical.

can be dragged by Qi Tian and another old comrade on the spot.

Seeing this, the woman who called the police couldn't help but take two steps back and hid behind Gu Chen.

"Dad, what's wrong with my dad, what's wrong with him?"

Although Qi Tian had already informed him of his death in the process of arresting Meng Yang, Meng Yang still couldn't believe that it was true.

It wasn't until he saw his father fall to the ground that the emotions in his heart exploded at this moment.

"You kid pretend to look like you?" Qi Tian couldn't help but snort coldly, and said, "Let me ask you, have you ever been to the house at about three o'clock this afternoon?"

"That's right, but so what? Who killed my father?" Meng Yang was still emotional.

Gu Chen, on the other side, had already begun to record Meng Yang's answer.

"Your nanny told us that after you came to the house, she had a big fight with your father, is there such a thing?" Qi Tian asked again.

Meng Yang was stunned for a moment, and then said, "Yes...... There is such a thing, but what does this mean? Isn't it normal for a father and son to quarrel? It's rare that you suspect me just because of a quarrel?"

Seeing that everyone didn't speak, Meng Yang also said angrily: "What do you mean? My father's death, you doubt me?"

After Qi Tian and Gu Chen looked at each other, they took the lead and said: "We have retrieved all the surveillance in the afternoon, except for the nanny in the house, it is you, and the nanny left after you entered the house, so it was only you and your father in the room at that time, isn't it?"

"I ......" Meng Yang suddenly felt speechless, feeling that he had fallen into a dead end after death.

Only then did I quickly recall the situation in the afternoon.

"That's right, it was my father and I who had to discuss things, so we had a big fight, so we let the nanny go home first. Meng Yang did not deny it.

"What are you willing to quarrel with?" Gu Chen put down the notebook and looked up to ask him.

"Because of the money. Meng Yang obviously also recognized Gu Chen and Qi Tian, who were the policemen he met in the afternoon.

But one yard is one yard, now it is a murder, and it is his father who died suddenly, so Meng Yang's reply has become serious.

"Because of the sneaker inventory I managed, I had financial difficulties, and I borrowed a lot of money from outside, but because I didn't agree with my father about the sneaker business, I had a big fight. ”

"He thinks that my shoe speculation is nonsense, and in his impression, mining is king, he wants me to give up all my collection and exchange these precious sneakers for cash to save my money. ”

"But that's absolutely impossible, these valuable sneakers are my collection, so I won't sell them at a low price. ”

Speaking of this, Meng Yang glanced at Gu Chen, he knew that Gu Chen understood this, because before going home in the afternoon, he had discussed a lot with Gu Chen, about topics such as sneaker dreams.

"And what happened in the end?" Qi Tian asked.

"Finally?" Meng Yang briefly recalled, and said: "In the end, we were both tired of arguing and sitting in the room, he still loved to drink so much, so he took a bottle of wine and drank it by himself." ”

"After I saw this situation, I took the opportunity to reason with him, he loves wine, collects wine, and I love basketball shoes, and it is a reason to love collecting basketball shoes. ”

"So I instilled that philosophy in him and told him that we're all collectors, and if he loves to collect good wine, why can't I collect those precious basketball shoes?"

"I showed him my financial statements and told him how I made money in the shoe industry, and he relented and agreed to give me a sum of money. ”

"Then you mean, you have already gotten the money?" Gu Chen asked curiously.

Meng Yang nodded and said, "That's right, but I have to transfer money tomorrow, so I also sat down and had a few drinks with my father, he was still at the door when I left, and it was usually the nanny who took care of the family." ”

"No wonder you didn't drive away because you had been drinking?" asked another old comrade.

Meng Yang nodded fiercely and said, "Comrade policeman, although I also like to drink, I will never drink and drive, please rest assured, this is why I don't drive a car, but go to the intersection to take a taxi." ”

"But after you left, your father died of strange poisoning. Qi Tian also kindly explained.

In Qi Tian's opinion, even if the reason given by Meng Yang is reasonable enough, in the entire small western-style building, only Meng Yang has the time to commit the crime.

And judging from the time of Boss Meng's death, it was precisely after Meng Yang left, these suspicions ...... Qi Tian will not let it go at all.

But how Meng Yang committed the crime, Qi Tian had no clue now, except for a few small objects found at the scene, he didn't find any traces of poison.

And just now Meng Yangxing was arrested outside, and the veteran Qi Tian also specially searched Meng Yang's whole body, and no poisonous drugs were found.

Without absolute evidence, the police simply could not use Meng Yang's assumptions as a reference.

"I think we have to call up all kinds of monitoring of the road between Meng Yang's coming out of the small western-style building and being arrested, and strive to grasp the situation after Meng Yang left. After thinking for a few seconds, Qi Tian's thoughts began to be simpler: "The rest of the clues, that is, to search in the small western-style building, I don't believe that I can't find toxic substances." ”

Qi Tian is determined to find evidence.

When Meng Yang was arrested, he never thought that he would be arrested, so he could not hide the poisonous substance.

And if the police can find out Meng Yang's strange behavior along the way, then finding out the toxic substance is just around the corner.

What is missing at the moment is this part of the surveillance footage......

If not, it must still be hidden in the small western-style building, as long as the small western-style building is searched in a carpet way, Qi Tian will not believe this Meng Yang will not admit it.

"Take Meng Yang back first, ask someone to come over and dispose of the body, and let's go back to the police station for other things." Qi Tian looked down at the table below, and it was not suitable for a small number of police officers to search at night.

We can only strive to send a large number of police officers to conduct a carpet search after dawn, and we may be able to achieve great gains.

Don't look at Meng Yang's non-confession now, he will cry when the time comes.

Meng Yang was taken into a police car and returned to the Haitang Police Station.

The Meng family's small western-style building is also temporarily closed, and no one is allowed to enter without permission.

Gu Chen sat alone in the office, using the master-level reasoning in his mind to start various simulations.

However, what made Gu Chen clueless was that from the current situation, he couldn't deduce how Boss Meng was poisoned and killed?

Qi Tian dragged a tired posture to the office, and when he saw that Gu Chen was still there, he couldn't help but take a step forward and said, "Why don't you go to rest?" This case will be investigated again tomorrow, and the answer will not be found tonight." ”

"Senior Brother Qi, who do you think the suspect is?" Gu Chen suddenly asked him.

"Do you need to talk about this? It must be this Meng Yang. Qi Tian said.

"Why?" Gu Chen asked again.

The time of death, the place of death, and the contradiction between Meng Yang and his Lao Tzu are all enough to show that the murderer is Meng Yang. ”

"And before our police entered Meng's house, the last two people Boss Meng contacted were the woman who reported the crime and Meng Yang. ”

But the woman who reported the case left before Meng Yang, which just shows that Meng Yang has a crime that cannot be cleared. ”

After some rhetoric, Qi Tian was also quite proud of his reasoning.

In other words, this is an attempt to use the surveillance screen to retrieve important information about the suspect.

"I think it's too early to tell. Just when Qi Tian looked proud, Gu Chen directly poured cold water on him and said, "Or there is a third possibility, the person who poisoned Boss Meng got up and was Boss Meng himself." ”

"What?" Qi Tian was stunned for a moment, and it took a long time to come to his senses and say, "Gu ...... Gu Chen, are you crazy? Who would kill themselves? Even if you have imagination, you have to have a basis, right?"

Qi Tian looked at Gu Chen very strangely, feeling that this bold assumption really scared him.

However, when he came to his senses and carefully analyzed Gu Chen's rhetoric, he suddenly felt a little bit of truth.

"Eh, Gu Chen, hearing you say this, it opened up another way of thinking. Qi Tian picked up the pen and paper on the table and began to write the three of them on paper.

"The woman who reported the crime can basically be ruled out, because of all the known conditions, she has no time to commit the crime, and she has no motive to commit the crime. ”

After crossing out the woman who reported the case, Qi Tian put a big question mark between Meng Yang and his father Boss Meng: "But the question is, if it is really as Meng Yang said, after he just had a big quarrel with his father, the two of them drank together in a friendly manner, then is there a problem with the wine?"

"Senior Brother Qi, you have finally opened your mind. Gu Chen also laughed dryly, took the pen in Qi Tian's hand, and wrote down the symptoms of his death under Boss Meng's name.

"Boss Meng's lips are purple, he died of poisoning, and we found a bottle of medicine at the scene, do you remember?" asked Gu Chen.

"Yes...... There is a bottle, it seems to be a medicine for gum inflammation, right?" Qi Tian said.

This is the information I got from the woman who called the police, and she still bought the medicine.

"That's right, I've read the instructions on the bottle, it's a cephalosporin antibiotic. Gu Chen took the bottle in the evidence collection bag in his hand and said, "This is the key to the problem." ”

Qi Tian was suddenly stunned for a moment, and asked weakly, "Could it be ...... Is there something wrong with the drug? That is, the woman who bought the medicine is also very suspicious, right?"

Gu Chen didn't speak, but under Boss Meng's name, he wrote cephalosporin antibiotics, and then another substance......
