Unlike the atmosphere of yesterday's meeting, everyone in Room 1 unconsciously felt a sense of frustration at this moment.

ZHAO GUANGMING'S DEATH CONFIRMED THE TRUE EXISTENCE OF RAGUEL, AND NOT ONLY THAT, BUT ALSO SOLEMNLY TOLD EVERYONE HOW TERRIBLE THIS UNKNOWN OPPONENT WAS.

He dared to confront the criminal investigation detachment head-on, mailed threatening letters, sent provocative text messages, and even after he succeeded, he still dared to send a message confirming that this was his masterpiece.

Chen Jianbin , Wang Tao and others have been criminal police all their lives, but they have never seen such an arrogant, cautious, and difficult opponent.

And now, Chen Guojun's autopsy report is the last straw for everyone, if some clues can be found, it is possible to find the other party's fox tail.

So, every detail counts.

Wang Tao had not seen the object in the photo, and looked at Chen Guojun with some doubts.

"It's a pacemaker!"

It was not Chen Guojun but Sun Baoqiang who answered Wang Tao's question, and Sun Baoqiang, who stood up, carefully recognized the words on the picture, and a familiar look appeared in his eyes: "This is a foreign-made pacemaker, my father just implanted this thing last month, and this thing alone costs 50,000 yuan!" ”

When Sun Baoqiang raised his head, there was a relieved look on his face, and he seemed to have a certain guess about Zhao Guangming's sudden death: "Old Chen, this thing was found from Zhao Guangming?" ”

Chen Guojun walked to the side of the projection screen, first nodded to Sun Baoqiang, signaling that he guessed correctly, and then looked at Chen Jianbin : "Zhao Guangming was implanted in the First People's Hospital last year This pacemaker, we have contacted the hospital, I checked Zhao Guangming's medical records and found that he has a more serious heart disease, last year not only installed a pacemaker, but also did a heart bypass surgery." ”

Everyone listened to Chen Guojun's report quietly, did not interject, there was a specialization in the art industry, although everyone also had some forensic common sense, but most of them judged the time of death and the like, and the specific analysis also required the professional conclusions of the doctors.

"Zhao Guangming died of insufficient blood supply caused by cardiac arrest, accompanied by a heart attack, and it can be determined that there are only two reasons for this, one is the malfunction of the pacemaker, and the other is the detachment of the stent caused by the blood clot falling off."

"Lao Chen, the possibility of a pacemaker malfunction should be very small, right?"

It was Sun Baoqiang who asked the question, because his father had just implanted a pacemaker, so he knew the most about this aspect: "Especially the pacemaker used by Zhao Guangming is the most famous brand in the world, and it is also the most expensive, and the doctor who operated on my father said that this brand of pacemaker has never malfunctioned." ”

"Lao Sun is right, so our first suspicion is that the deceased may have been negligent in taking medication, or the murderer directly moved his hands and feet on Zhao Guangming's antithrombotic regular medication, causing the blood clot to fall off and cause Zhao Guangming's death."

Chen Guojun's suspicions are very reasonable, and anyone with a heart stent knows that once a heart bypass surgery has been performed, specific drugs must be taken for a long time, which can be said to be a lifelong medication.

The series of actions planned by the murderer could not have been carried out in a hurry, and it must have been carefully planned and planned, so it is very likely that the other party knows about Zhao Guangming's condition.

Then to kill Zhao Guangming, as long as the other party's medication is accurately controlled, it is possible to make Zhao Guangming die violently within a fixed period of time.

However, Chen's next conclusion overturned his suspicions: "But we detected the ingredients of the drugs he took in Zhao Guangming's body, the residual measurement met the normal use standards, and we found no blood clots that fell off in the heart stent." ”

No blood clot was found, and the drug residue test was normal, so what method did the other party use to make Zhao Guangming have a heart attack?

There are two reasons in total, blood clots and pacemakers, now that no blood clots have been found, it can only be the second possibility, Chen Jianbin tapped his index finger on the table, and his voice was low: "Old Chen, do you mean that the murderer moved his hands and feet on the pacemaker?" ”

"Team Chen, this ...... Basically, it's impossible. ”

Sun Baoqiang directly questioned: "When the pacemaker is implanted, it is very strictly tested, not just a surgeon, but after the handover of equipment, nurses, doctors and other links, it can be implanted into the patient." ”

"Not only that, but it is necessary to recheck and adjust the parameters within a period of time after implantation, go to the hospital for regular check-ups, and charge the battery if the rechargeable battery is used."

"EVEN IF THIS RAGUEL HAS GREAT ABILITY, IT IS IMPOSSIBLE TO DO THINGS ON A PACEMAKER!"

"Lao Sun, what you said is right, the reliability of pacemakers is indeed very high under normal circumstances, but what if the other party does not do it directly, but through other means?"

Other ways?

Sun Baoqiang showed a suspicious expression: "The principle of the pacemaker is that artificial pulses stimulate the heart to contract regularly, except for the strong magnetic field......"

"Huh? Lao Chen: Do you mean a strong magnetic field? ”

"That's right," Chen Guojun switched the projection picture again: "At noon today, we have sent the pacemaker in Zhao Guangming's body to the First Life Hospital for testing, although I don't know what method the other party used to damage the pacemaker, but the answer given by the hospital is that the pacemaker has been interfered with by a strong magnetic field and has been completely damaged." ”

"It is precisely because of the damage of the pacemaker that Zhao Guangming, who relied on the pacemaker to survive, was able to die in an instant without alarming you who slept with him."

The pacemaker was damaged by the interference of a strong magnetic field, resulting in Zhao Guangming's death.

The murderer's means of causing death have been found, but how did the other party do it?

You must know that Zhao Guangming was already taken to the criminal investigation detachment yesterday afternoon and died at three o'clock in the morning, which means that the strong magnetic field released by the other party at that time killed Zhao Guangming.

With this clue, a lot of things can be determined.

Because even a magnetic field cannot be generated out of thin air, Chen Jianbin looked a little excited, three o'clock in the morning is too good, although killing Zhao Guangming at this time will not immediately cause the police to find out, but it also means that the murderer is easier to expose, after all, strong magnetic fields are not so easy to generate.

Chen Jianbin turned his head to look at Xia Dong, and his tone was a little urgent: "What kind of strong magnetic field can damage a pacemaker?" ”

Xia Dong pondered for a moment, she was not particularly familiar with pacemakers, but as a technical master, she knew the basic common sense: "First of all, the stability of the pacemaker itself is not low, and it is impossible for the magnetic field generated by ordinary electrical appliances to interfere with or even cause damage to the pacemaker." ”

"So this kind of device must be specially made, but any strong magnetic field has a certain range, and I have to check some information to give an answer."

"Okay, Xia Dong immediately started the investigation and found out the other party's modus operandi as soon as possible."

CHEN JIANBIN GAVE AN ORDER WITH SOME EXCITEMENT, THIS IS SINCE THE FIGHT WITH RAGUEL, CHEN JIANBIN THINKS THAT THE MOMENT WHEN HE IS CLOSE TO THE OTHER PARTY RECENTLY, WHEN ANYONE IS NOT MYSTERIOUS, IT IS WHEN HE IS EXPOSED TO THE SUN TO BE JUDGED.

"And Wang Tao, you check the surveillance video near the detachment at about three o'clock in the morning today, since the other party uses strong magnetic field interference, the distance must not be too far, check if there are any suspicious people!"

While Chen Jianbin made a major discovery here, Song Chuan also made a major discovery in the self-surrendering net bar.

In the hall, in the third row of computers, in front of a machine near the window, a middle-aged man is surfing the Internet, and there is a pair of crutches next to him!

Qin Feifei, who was following Song Chuan, covered her small mouth excitedly, the fat-headed fish on her chest pressed against Song Chuan's back, and whispered excitedly in Song Chuan's ear: "Could it be the man on crutches?" ”
