There was a sudden silence for a few seconds.

Everyone looked at each other and didn't seem to dare to be too loud.

According to what Gu Chen said, if Dr. He dies unexpectedly, it will not be possible to assess the blood pressure value.

So no one knows how low his blood pressure was in the moments before the accident.

And the doctor at the hospital is likely to pass it off and conclude that he died in a car accident.

Lu Weiwei was a little uneasy, and hurriedly asked Gu Chen: "Then Senior Brother Gu, if, I mean if, if Doctor He really died unexpectedly as you said, can you still find some clues?"

"It's still possible. Gu Chen took a deep breath and explained to everyone: "If we are more diligent in tracking, maybe we can still confirm the blood content of different drugs that Dr. He is taking." ”

After glancing for a week, Gu Chen said again: "Because we have all watched the video, Dr. He in the video did have dizziness symptoms at the moment before the car accident. ”

Combined with the sudden fainting that occurred at the public welfare stall before, from these two points, it is not an accident. ”

"Because Dr. Ho is delirious or even unconscious, we can weigh whether Dr. Ho has had a heart attack, stroke, arrhythmia or low blood pressure. ”

"If the test results of Dr. He have no signs of heart attack or stroke, but the blood content of high blood pressure medication is abnormally high, then this is a bit weird, at least Dr. He himself will not take too much medicine, right?"

"Yes, Dr. Ho's consumption of drugs is very strict, and it is impossible to consume too much. ”

Zhang Xiaomei, as He Zhengjun's colleague, knows He Zhengjun's situation best, so Zhang Xiaomei is also very sure.

Gu Chen thought thoughtfully: "If Dr. He doesn't have suicidal thoughts, he is being framed by others." ”

Looking at everyone in front of him, Gu Chen said again: "I think Dr. He probably didn't take the medicine correctly, or took too much medicine, which caused the blood pressure to drop and cause an accident, what do you think?"

"Agreed. Lu Weiwei was the first to nod.

Then came Officer Wang and Yuan Shasha, the two hesitated slightly, but still agreed with Gu Chen's opinion.

The most puzzled is Zhang Xiaomei, who hesitated for a long time, but she couldn't believe that her colleague Dr. He was in a car accident because of this result.

"Zhang Xiaomei. Seeing that Zhang Xiaomei was still hesitating, Lu Weiwei couldn't help but remind her.

"Huh?" Zhang Xiaomei was stunned for a moment, and said contradictory in her heart: "I...... I still don't believe this is happening. ”

She glanced at Gu Chen and continued to ask, "Then apart from this situation, is there no other possibility?"

"I'm speculating, too, and I'm not saying it has to be that way. Seeing that Zhang Xiaomei was too emotional, this made Gu Chen can't help but have a trace of suspicion.

"But...... What if it's something else?" Zhang Xiaomei clasped her hands tightly, as if she was also thinking about something.

Gu Chen walked up to her, looked Zhang Xiaomei who was a little overly nervous up and down, and asked her with a smile, "Then what do you mean?"

"I don't know. ”

"You don't know? Not yet. ”

"But ......" Zhang Xiaomei sighed, and said helplessly: "But I don't know what to say, maybe you're right." ”

Gu Chen saw that Zhang Xiaomei couldn't give other clues, so he explained to her: "I just speculated based on Dr. He's several abnormal conditions, combined with the characteristics of his hypertension disease, and the overdose reaction of hypertension medication. ”

Of course, it is not necessarily correct, but for now, this speculation is more in line with Dr. He's current condition. ”

Looking down at his watch, seeing that the time was getting later and later, Gu Chen asked Zhang Xiaomei, "Did Dr. He go out after work?"

"Yes. Zhang Xiaomei said.

"Then did he take high blood pressure medicine?" Gu Chen asked again.

"Nope. Zhang Xiaomei still shook her head.

"I see. Gu Chen nodded slightly and patted Zhang Xiaomei on the shoulder: "Xiaomei, you go back and have a good rest first, if there are any missing clues that need to be provided to us, remember to contact Lu Weiwei." ”

Zhang Xiaomei didn't seem to be in a good state, just nodded slightly, and then walked thoughtfully in the direction of home.

......

......

At night, there are fewer and fewer vehicles on the road.

Lu Weiwei looked at Gu Chen with some confusion: "Senior Brother Gu, don't you think this Zhang Xiaomei's situation is abnormal today?"

"Absolutely. Gu Chen stood next to his vehicle, also leaning against the door and said:

Zhang Xiaomei's reaction was fine, but when I speculated that Dr. He might have been dizzy due to taking too much medication for high blood pressure, her gaze clearly fluctuated strongly. ”

"I felt it too. Officer Wang stepped forward and couldn't help but say: "This girl seems to have remembered something, but she doesn't dare to say it clearly, she seems to have something hidden in her heart." ”

"Then do you think she's making trouble?" said Yuan Shasha, making her hypothesis.

Gu Chen hesitated for a few seconds, and couldn't answer, so he could only shake his head: "At present, this kind of assumption can exist, and it can also be boldly assumed, but if things are really what we think, then there may be many clues involved in this that we don't have master." ”

"What do you mean......" Lou asked.

"The interpersonal communication between them. Gu Chen said.

Lu Weiwei still didn't understand, and continued to ask: "Are you saying that the communication problems between Dr. He and his colleagues caused someone to do something to him?"

Gu Chen nodded slightly, but said: "If you look at it purely from interpersonal communication, it must not be Zhang Xiaomei, because the relationship between the two of them should be good, it may be other factors." ”

Thinking of this, Gu Chen turned his head and said to Officer Wang, "Senior Brother Wang, please contact Senior Brother He and ask him to find out who He Zhengjun had been in contact with in the hour before he came to the public welfare booth, and had he drunk any drinks?"

"Okay, I'll get in touch. Officer Wang didn't hesitate, he knew that Gu Chen wanted to start from the point in time before He Zhengjun fainted.

As you have just discussed, if someone deliberately puts effort into the process, then there needs to be an interval of one to two hours between taking the medication and having a car accident, and it can be after a meal that he is given all the pills. ”

But if you want He Zhengjun to absorb those excess drugs more quickly, you have to crush the pills, or open the capsules and pour out the powder, and arrange for Dr. He to take it with a small amount of food.

In this way, the absorption rate of the drug will be much faster, the effect of the drug will be faster, and the impact will be more drastic.

As a result, symptoms of low blood pressure appear within 10 to 30 minutes.

Therefore, Officer Wang speculated that Gu Chen wanted to count from when He Zhengjun fainted, and push forward for 10 to 30 minutes to see what people he had come into contact with and what he had drunk.

Picking up his mobile phone, Officer Wang began to contact He Junchao......

Time passed minute by minute, and when everyone was sitting in the car and waiting quietly, Officer Wang Gu Chen finally received He Junchao's video message in the group.

It didn't take long for the phone to call Gu Chen directly.

"Senior Brother He. Gu Chen swiped the answer button and clicked on the hands-free.

"Gu Chen, I have also checked the monitoring situation you asked me to investigate, He Zhengjun once met Zhang Xiaomei at an intersection before he came to the public welfare stall. ”

"Zhang Xiaomei?" Gu Chen was stunned, and his eyes involuntarily looked at everyone.

Then he said: "You go on, when you see Zhang Xiaomei, is there any interaction between the two of them?"

Yes, Zhang Xiaomei gave him a thermos cup. ”

"Then what about later, has He Zhengjun seen anyone else?" Gu Chen seemed to have a sense of foreboding.

And He Junchao on the other end of the phone was very sure: "No, I transferred the distance from He Zhengjun after work to the public welfare stall location, except for meeting Zhang Xiaomei on the road and taking a thermos cup from Zhang Xiaomei's hand, I haven't contacted anyone else." ”

"Then did he drink water?" Lu Weiwei hurriedly asked him.

"Drink water?" He Zhengjun on the other end of the phone was stunned for a moment, and quickly said: "It seems that I have drunk, while waiting for the traffic light." ”

"Smack!" Officer Wang slapped his thigh: "That's right, if that's the case, then everyone's situation, as Gu Chen speculated just now, there is a big problem with this glass of water." ”

"Yes, that's the problem. Getting this clue, Lu Weiwei was even more excited than Officer Wang.

But after a while, Lu Weiwei asked again: "Then isn't this glass of water the key evidence of this car accident?"

"Where's the water cup?" Gu Chen picked up his phone and asked again.

He Junchao couldn't resist the continuous questioning of these people, so he hurriedly said: "You have to let me slow down, give me some time, and let me look for it again." ”

"Give you 2 minutes. Gu Chen said.

"Okay. He Junchao didn't bargain and directly began to continue the search.

Everyone sat in the car and waited for 3 minutes, but He Junchao did not respond.

Lu Weiwei couldn't sit still, and hurriedly said loudly into her mobile phone: "I said He Junchao, have you found it?"

"Find ...... I found it, but I ...... But at the scene of the crash, it was gone. He Junchao on the phone looked a little helpless.

Gu Chen took a deep breath and said lightly, "You say be specific." ”

Specifically, when the car accident occurred, He Zhengjun's battery car parts were knocked to pieces, and then the traffic police also rushed to the scene, and the ambulance also came. ”

After He Zhengjun was sent to the hospital, and the traffic police also roughly cleaned up the debris and cleared the road, maybe the water cup was also at the scene, but then the sanitation workers came, and the scene was cleaned, and it is estimated that it was cleaned up. ”

"Okay, got it. As soon as the words fell, Gu Chen had already started the vehicle.

Gu Chen knew that the scene of the car accident might have become the key for everyone to find clues.

But when he heard the news that the scene had been cleaned, Gu Chen's face was obviously a little ugly.

If it is cleaned up, it means that the last trace of clues may be interrupted.

But if this is the case, maybe He Zhengjun's car accident will become a mystery, whether it is his own overfatigue, or because of dizziness caused by low blood pressure, no one will say clearly at that time, and the investigation will become more and more complicated.

Gu Chen didn't think much about it, and directly started the vehicle and rushed to the scene.

......

......

When I came to the scene of the accident, there were already obvious traces of cleaning on the road at this time.

And the bloodstains just now can still be clearly seen on the road.

After Gu Chen got out of the car, he hurriedly searched the roadside at the scene.

Everyone focused on searching the location of the flower beds on the side of the road, which were already near the garbage cans.

Sanitation workers sweep the garbage on the roadside, and most of them will empty the garbage into hand trolleys, which will then be transported to the garbage station.

There are also small amounts of garbage that sanitation workers throw into nearby roadside bins.

But in either case, nothing was found at the scene.

On the other hand, according to Gu Chen's request, Officer Wang also contacted several traffic police officers who were cleaning up the wreckage of the battery car at that time to confirm whether any water cups had been picked up.

But the results were all no......

Officer Wang hung up the phone a little depressed, spread his hands at Gu Chen and said, "Look, I can't find it at all, everyone said they didn't see the water cup." ”

"And at that time, they were cleaning up the materials that had fallen from the battery truck, that is, the X display racks, posters, yoga mats, and nothing else. ”

Gu Chen frowned, simply sat on the side of the road, then took out his mobile phone and continued to check according to the previous surveillance footage.

From the moment of the car accident and impact, Gu Chen used his specialty-level observation power to watch it more than a dozen times.

However, due to the extremely fast impact speed and the fact that the picture capture was not clear, Gu Chen could only find that the wreckage parts of the battery car were scattered all over the place.

But while everyone was entangled, the sound of squirming sounded again.

Everyone stopped looking, everyone stood up, everyone turned their heads to look at the source.

An old lady wearing a cleaner's vest is using a bamboo broom to clean up roadside debris.

Gu Chen slowly walked up to her with everyone and asked, "Auntie, is you the one who cleaned up the scene of the car accident just now?"

"Yes, what's wrong?" asked the old woman.

"Have you ever seen a cup? The kind of thermos that drinks water. Lu Weiwei hurriedly asked.

The old aunt was stunned: "What thermos cup? I didn't see it." ”

"Ahem, that's right. Officer Wang coughed twice, and couldn't help but say: "That cup was used by the injured person, it was probably a blue cup, and the length was about this ......."

In order to make the appearance of the cup more concrete, Officer Wang began to gesture with both hands.

However, the old lady's expression did not fluctuate......

After listening to Officer Wang's introduction, he shook his head directly: "I don't know, I didn't see the thing you said." ”

"And isn't it just a cup? How much is it?

"It's not a question of whether to find it or not, whether it's expensive or not, because of this ......"

"I'm going to sweep the floor, don't get in the way. The old lady didn't seem to want to listen to Officer Wang anymore, so she directly swiped under his feet with a bamboo broom, and Officer Wang instinctively stepped back.

"Sha, Sha, Sha, Sha......"

The rhythmic sound of sweeping the floor sounded again.

But at this moment, Gu Chen found a white plastic bag hanging in the corner of the trolley garbage truck not far away.

However, on the inside of the white plastic bag is a prototype of a blue thermos cup.

Gu Chen frowned and walked slowly towards the garbage truck.

After that, remove the cup directly from the plastic bag.

At this time, this blue thermos cup is very similar to the cup used by He Zhengjun in the surveillance video sent by He Junchao before.

Moreover, there are many friction scratches on the outside of the blue thermos cup, and there are obvious impact marks on the lid and bottom corners of the thermos cup.

"Could it be...... Is this the cup?" Gu Chen couldn't help but wonder.

"I'll see. Seeing this, Officer Wang hurriedly took it in his hand and observed.

At this moment, the old lady sweeping the floor in front of her suddenly turned her head to look and found that several people were holding their own things and observing.

The old lady's face suddenly darkened, and she instantly dropped her broom and ran back.

She snatched the thermos cup from Officer Wang's hand and shouted angrily, "What are you doing?

"Not ......"

"What isn't? I saw it all? You took it from my bag. ”

Saying this, the old lady opened the white plastic bag with a suspicious face, and in an instant, several empty bottles of mineral water fell to the ground.

Officer Wang was a little helpless, and quickly explained: "We took it from your bag, but we just want to confirm whether it is the cup of the person injured in the car accident." ”

"No, they all said no. The old lady seemed to be resolute and unreasonable.

Officer Wang just wanted to step forward to theorize, but was stopped by Gu Chen.

Gu Chen took the initiative to walk up to the old lady, and also said with a smile: "Old lady, we don't mean anything else, we just found that there are many scratches on this cup, and it seems that this cup is a trace left by bumps and bumps in high-speed rotation." ”

"I just wanted to make sure if it was the object that the friend lost in the car accident, and nothing else. ”

Seeing that Gu Chen spoke politely, the old lady was also polite: "This is what I picked up, and if you say a broken cup, it's useless for you to keep it, I can still sell it for some money...... Money ......"

As soon as the old lady said money, Gu Chen had already taken out a 100 yuan bill from her wallet.

"100 yuan, buy your cup, is it enough?" Gu Chen said.

The old lady was stunned, her eyes lit up and she said, "This ...... How embarrassing is that? These 100 yuan can buy a lot of plastic bottles. ”

"Take it. Gu Chen handed over a hundred yuan to her, then took the cup directly from her hand and asked her, "You haven't poured the water in this cup, have you?"

"No, no, no. After getting Gu Chen's 100 yuan, the old lady was so happy that she answered all questions: "When I picked it up, it was like this, and I didn't see much water in it, so I threw it directly into the plastic bag." ”

"That's good. Gu Chen breathed a long sigh of relief, glanced at several colleagues and said, "Let's go, go to the technical department of the city bureau." ”

Sitting back in the car, Gu Chen carefully took out a plastic bag, wrapped the water cup, and put it to the side.

Then drive to the technical section of the city bureau.

Officer Wang was a little unhappy and said: "I said Gu Chen, just the old lady just now, can you give her 100 yuan? ”

"You also say she loves to be cheap. Gu Chen glanced at Officer Wang in the rearview mirror of the car, and said, "It's not a matter if you can solve it with money, in my place, time is the most valuable." ”

......
