I am a super cop

Chapter 207 Blue Gas Bottle

Since Gu Chen locked down the two biggest suspects, he started his next move.

All the whereabouts of the two people that night were investigated one by one.

It can be said that Zhao Mingming's poisoning time within 27 minutes can be basically determined to be deliberately planned by someone.

However, there are two options before him. One is to call Zhang Wen and Han Wenfeng to the police station for questioning. This is a basic operation. After that, call again.

Obviously everyone is in favor of the latter...

"Old Ding, I have to trouble you to take another look at the surveillance video of Zhang Wen and Han Wenfeng." Police Officer Wang held the investigation report submitted by Gu Chen and turned to Officer Ding beside him.

"I need to make a quick trip, right?" Officer Ding asked in a crisp manner, anticipating Officer Wang's move, and said, "Come on, anyway, the coffee in the dispatch room is pretty good, so it's okay to have a little time."

Gu Chen and Lu Weiwei turned their heads together, and saw Police Officer Ding running there non-stop, holding an oversized thermos cup in his hand.

"Old Ding is really worthless!" Lu Weiwei smiled, and quickly looked at her thermos, thinking that she could also decorate it.

"Gu Chen, are the two suspects you mentioned reliable?" Police Officer Wang had some doubts.

After all, upon waking up, Gu Chen and Lu Weiwei had already completed all the investigations.

This is the result that Police Officer Wang most hopes to see...

"Zhang Wen and Zhao Mingming should have the most direct conflict, because the opportunity to perform on the same stage with John Lauer originally belonged to Zhang Wen, who is more skilled, but Zhao Mingming's father and his teacher Wang Dewen gave this opportunity to Zhao Mingming. , so the person most likely to hate Zhao Mingming should be Zhang Wen."

Gu Chen organized the information he got from Zhao's father into materials, so he deduced that the person with the most murderous motive is Zhang Wen.

"I also agree with Junior Brother Gu's judgment." Lu Weiwei couldn't help interjecting: "Everyone knows that being able to perform on the same stage with the world's top violinist John Lauer is a rare opportunity, especially for young Musicians are well-known and have high value, and this kind of competition is quite fierce.”

"Also, when Wang Dewen knew that Zhao Mingming's skills were not as good as Zhang Wen's, he insisted on bringing Zhao Mingming, who was a little less skilled, onto the stage. This is very telling."

Gu Chen also wrote the names of the two on the question board, and said: "In this way, Zhang Wen must hold a grudge in his heart. Freezing three feet does not happen overnight, and the conflict between the two has a long history."

Afterwards, Gu Chen showed the video of the two in the corridor, where the two refused to give in to each other, and showed Officer Wang: "Look, Senior Brother Wang, the two of them are in a state of turmoil, and the trash talk is enough to explode the old man." long time."

"Hehe, these two guys are really interesting." Police officer Wang was also amused by the video of the quarrel between the two, and asked casually, "What about Han Wenfeng? What is the basis?"

"He was beaten up by Zhao Mingming, who said he was neither male nor female." Gu Chen said.

"That is to say, these two people also have a long-standing grievance?" Officer Wang asked.

"That's right, at least it's the kind of people who hate each other when they meet, and talk bad about each other when they meet." Gu Chen hesitated, and then said: "However, this kind of grievance will not develop to the stage of poisoning, after all, speaking Korean Zhao Mingming is not the only one who is angry with Feng Niang, I think Zhang Wen needs to investigate carefully."

"I also agree." Lu Weiwei agreed again: "This Zhang Wen's family background has just gone from peak to trough, and the family still owes debts."

"Think about it, everyone. He was a son of a rich family before. When he and the children of these rich families were studying under Wang Dewen, we all had a balanced relationship."

"But suddenly one day, my family fell into poverty, and I couldn't even pay the teacher's tuition fee. In the end, I had no choice but to become a small assistant under the pity of the teacher, and even the performance opportunity that should belong to me, They were all ruthlessly taken away."

"This time is the saddest and most difficult time to accept. After all, if I can seize the opportunity to perform on the same stage with the world's top violinist John Lauer, maybe I will become famous and gain both fame and fortune. .”

"At this time, Zhang Wen, who had hoped to make a comeback, was ready to meet his glorious moment, but Zhao Mingming appeared in the middle, and abruptly took away the opportunity that originally belonged to him, ruthlessly."

"The most terrible thing is that this is my deadly enemy. Can this make Zhang Wen calm? Anyway, if this kind of thing happens to me, maybe I won't be able to calm down."

Lu Weiwei talked a lot, reasoning and analyzing all kinds of reasoning, which made Officer Wang startled for a while.

However, Police Officer Wang did not know that these were the exact words Lu Weiwei heard from Gu Chen on the way back to the Furong Police Station.

"Yes, Lu Weiwei." Officer Wang said in surprise, "Your reasoning really impresses me."

"Following Junior Brother Gu to handle the case, there will always be some improvement." Lu Weiwei is not greedy for credit, and has to mention Gu Chen at the critical moment.

Not long after, Officer Ding, who went to the dispatch room to check the monitoring, also came back.

The hot coffee in the thermos was still steaming, and the strong coffee smell made Lu Weiwei sniff her nose: "Old Ding, have you ever drank this coffee?"

"Not yet, I'll drink it when I'm ready."

"Okay, pour me some." Lu Weiwei pursed her tongue like a greedy cat.

Officer Ding poured coffee generously, and asked Lu Weiwei suspiciously: "I said, Weiwei, you are so greedy, could you be tricked away with a lollipop when you were a child?"

"Yeah." Lu Weiwei sipped her coffee and said with a smile, "I'd better be lied to, especially suitable for being a girlfriend."

After finishing speaking, Lu Weiwei secretly glanced at Gu Chen again.

At this moment, Gu Chen has already used the video copied by Police Officer Ding to check Zhang Wen's specific movements yesterday.

This time, Gu Chen did not follow the chronological order, but started playing from the time closest to Zhao Mingming's poisoning.

first video.

It was also the scene of Zhang Wen and Zhao Mingming imploding trash talking in the channel. Gu Chen directly clicked to exit, and then entered the second video.

In the video, Zhang Wen handed a bunch of car keys to Wang Dewen in the backstage passageway, and then left after a few simple explanations.

Then there's the third video.

The scene came to the parking lot. Zhang Wen drove the imported car and parked it in the parking space of the theater.

Then, after making sure that there was no one around, he got out of the car and entered the theater.

And at this time, it happened to be the end of John Lauer's concert.

All the VIP audience got up and went to the backstage of the Grand Theater, preparing to line up for a separate photo with John Lauer.

Seeing this, Gu Chen didn't click on the next video, but fell into deep thought.

"Junior Brother Gu, isn't the car that Zhang Wen is driving the same imported leading car? It is also the car that Zhao Mingming drove later." Lu Weiwei also found out the trick, and couldn't help asking the question.

Police officer Wang stared, and immediately went to check the situation, and asked after a while: "This Zhang Wen, why is he driving the same car as Zhao Mingming?"

"Maybe the owner of this car is Wang Dewen, otherwise Zhang Wen doesn't need to hand over the car keys to him." Gu Chen also asked this question based on the previous video: "Besides, before Zhang Wen handed over the car keys to Wang Dewen, Zhao Mingming has already gone to the parking lot, so the two car keys of this car are on Zhao Mingming and Zhang Wen respectively."

"One car key for each person?" Police Officer Wang looked at Gu Chen beside him in amazement, and said, "Then this car must belong to Wang Dewen, otherwise, given the grievances between Zhang Wen and Zhao Mingming, he would never have given away his car." Give it to each other to open."

"That is to say, Zhang Wen is very likely to have tampered with this car, and he was the only person who had driven the car before Zhao Mingming got in the car." Lu Weiwei suddenly felt terrified, as if the truth was slowly approaching .

"Since Zhang Wen is fine with this car, how can something happen to Zhao Mingming? Moreover, forensic doctor Liu has already given a conclusion on the inspection of the vehicle, and found no toxic substances hidden in the car. "

Officer Wang also denied Lu Weiwei's opinion based on Liu's forensic doctor's conclusion last night.

In his opinion, the possibility of toxic substances in the car is extremely low, otherwise any residue may be detected by forensic doctor Liu.

Officer Ding blew on the cool air, put the hot coffee in the thermos cup into his mouth, took a few sips, and said: "This Zhang Wen has been to a car repair shop before, and it seems that there is something wrong with the car, but he soon found out It’s out, there’s a video inside, you can watch it for yourself.”

Before he finished speaking, Gu Chen clicked on the video marked as a car repair shop.

In the picture, Zhang Wen drove the car into a small car repair shop, and drove the car away not long after, only staying for 3 minutes back and forth.

"What the hell is this guy doing? Is he repairing a car?" Lu Weiwei was confused and said, "Can't fix anything in 3 minutes?"

She knows that there are not a few hours for car repair and maintenance, but in the video, the time is indeed 3 minutes.

Lu Weiwei looked at Police Officer Wang beside her and asked, "Old Wang, what can you do in three minutes? Tell me."

"This?" Police officer Wang was also confused by the question, hesitating for a few seconds before saying: "It is impossible to change the engine oil in 3 minutes, it seems possible to add some coolant and wiper washer fluid."

"And... inflating?" Gu Chen's eyes lit up when he was reminded by Police Officer Wang: "The vehicle can be inflated in 3 minutes."

"That's right." Officer Ding agreed, "It doesn't take much time to inflate."

At this moment, Gu Chen found out the location of the repair shop, showed the phone map in front of everyone, and said:
"Look, this small shop is very remote, and there are many large auto repair shops around the Grand Theater, but this Zhang Wen chose to go far and drive an imported luxury car to a remote small shop for repairs, or maintenance. , I'm afraid it's hard to say, right?"

"Junior Brother Gu, what do you mean... this repair shop is tricky?" Lu Weiwei frowned slightly, as if she also felt the same way: "If there is really a problem with this shop, then we have to go and investigate immediately."

"It's really unreasonable to drive a luxury car to a remote shop."

Police officer Ding also agreed with Gu Chen's opinion, raised his head and said, "Who would dare to hand over an imported luxury car to this small repair shop with an open-air tent?"

"Then what are you waiting for? Go to this store and have a look." Officer Wang got up immediately. He is no longer the salted fish he was at the beginning, and acting immediately is a good habit he learned from Gu Chen.

Several people reached a consensus and drove directly for three to 10 minutes, and finally found this car repair shop in the alley after the confirmation of the mobile phone navigation.

There was originally a canopy built at the door, which may have been demolished by law enforcement agencies due to illegal construction.

So now there are only a few pillars left, with various lube advertisements posted on them.

Two cars can be parked in the store at the same time, and there is almost no monitoring equipment around except for the camera at the intersection.

Seeing that there was a business coming, the owner of the small shop also took the initiative to ask: "Dear police comrades, what's wrong with your car?"

Gu Chen didn't reply directly, but showed Zhang Wen in the screenshot of the video on his mobile phone in front of the store owner and asked, "This person, did you come to your store last night?"

The shop owner with a strong figure bent down to take a look, and after thinking for a few seconds, he said lightly, "I seem to have a little impression."

"He was driving an imported luxury car, and he only stayed in your shop for 3 minutes." Lu Weiwei stood aside and continued to remind.

The store owner just "oh" and said, "I remember, there is such a person."

"Then what is he doing here?" Officer Wang asked.

"The person who came to inflate said the tire was flat." The owner of the repair shop said.

"Are you doing nothing else?" Gu Chen asked.

The store owner scratched the back of his head, feeling like he was being interrogated, but he quickly remembered something, and hurriedly said: "By the way, he asked me if there was any nitrogen in the store and wanted to add some nitrogen to the tires. I said no, Then he took out a can of blue vials from the car, said he had it, and asked me to use the gas scale."

Gu Chen and Lu Weiwei looked at each other, feeling that this was interesting.

Officer Wang hurriedly asked behind him, "Then what happened next?"

"Later? Then I agreed and charged him ten yuan. He switched on the air scale and filled the tires with nitrogen." The store owner recalled for a few seconds, and then said: "By the way, he is very skillful. I just don’t understand tire pressure.”

Gu Chen frowned, and asked, "How do you say that?"

"Because his tire pressure was too high, I also reminded him that it was enough, and the tire might blow out after reinflation, but he still overfilled it."

Afterwards, the owner of the repair shop took out a pack of cigarettes and handed them to Gu Chen, Officer Wang, and Officer Ding in turn.

Several people didn't confiscate it, so he ordered it for himself, smoked it patter, and said casually: "He didn't listen to my suggestion, so I didn't talk too much. Anyway, this is not my car. Whether there is a puncture or not is not the same as the car. What does it matter to me?"

"How high was the tire pressure?" Gu Chen asked.

"It's very high, and it's seriously exceeded the standard." The shop owner said.

"Then what about the blue vial containing nitrogen?" Lu Weiwei asked.

The shop owner looked around, pointed to a garbage dump in his shop and said, "It's there, he said that the nitrogen has been used up, I said this bottle is good, leave it to me, he didn't agree, he insisted on taking it away , Later, when he drove the car to the intersection, he threw the blue bottle from the car into the roadside trash can."

"I was amused at the time. He didn't want it himself, but he didn't give it to me. This thing should be worth some money, so I'll pick it up."

After thinking about it, the shop owner said again: "If you want to take it, but you have to pay for it, just give it a little thought."

Lu Weiwei walked over, picked up the blue gas bottle, and was about to put her nose close, but was stopped by Gu Chen who was at the side.

"Senior Sister Lu, I'd better hand it over to Forensic Doctor Liu for testing first."

"Okay." Lu Weiwei nodded, and took out a folded transparent evidence collection bag from her equipment.

After putting on white gloves, seal the gas bottle.

Officer Wang gave some money and asked the shop owner to issue an invoice, and they left by car.

On the way to the technical department of the Municipal Bureau, Officer Wang, who was driving, glanced at Gu Chen beside him, and asked, "Gu Chen, what do you think?"

"Maybe this is Zhang Wen's modus operandi." Gu Chen said.

"Let me guess." Lu Weiwei in the back row frowned slightly, and after thinking for a few seconds, said: "This Zhang Wen may not be filling the tires with nitrogen."

"Smart." Gu Chen suddenly grinned: "Senior Sister Lu is right."

"That is to say, the gas bottle is likely to contain poisonous gas?" Officer Ding also asked curiously.

Gu Chen nodded and said: "I have carefully watched the video of Zhao Mingming getting into the car. After he got into the car, he opened the door and squatted in the left front of the car for a long time. I think he must have found the left front tire. The tire pressure was too high, so I went there to deflate it."

"So, this is Zhang Wen's cunning." Lu Weiwei suddenly realized.

Gu Chen nodded and said: "That's right, this Zhang Wen used the stored toxic gas to forcibly inflate the left front tire, which was already under normal tire pressure, and then drove an imported luxury car with seriously over-inflated tires, and parked in the car. Grand Theater parking lot."

"Then Zhao Mingming, who came to drive to lead the way, started the car and found out the warning that the tire pressure was too high. Then he got out of the car and found that the tire was too inflated, so he released the air from the left front tire to stabilize the tire pressure. "

"But he doesn't know that the left front tire has been filled with poisonous gas by Zhang Wen at this moment?" Police Officer Wang said.

"That's right." Gu Chen nodded and said, "While releasing the gas, a large amount of toxic gas volatilized, making Zhao Mingming inhale the poisonous gas unknowingly."

"But at that time, he didn't have any adverse reactions immediately, so he continued to enter the vehicle and prepared to drive to lead the way."

"However, while driving on the highway, with the inhalation of the poisonous gas into the lungs, causing various adverse reactions, Zhao Mingming began to experience severe delirium, and his whole body began to foam at the mouth, which led to the accidental car accident last night. What happened is what we all saw."

Based on the various pictures in the video and the blue inflatable bottle, Gu Chen made his own reasonable reasoning.

Everyone also agreed, but the most important thing is that all the conditions will be considered valid only when Liu's forensic doctor's final test results prove that the gas contained in the blue gas bottle is indeed poisonous.
