The research and development of a drug requires a lot of human, material and financial resources, and there is no guarantee of 100% success.

But once the research and development is successful, it will be a great profit, and at the same time, it will also change the history of human medicine.

Based on previous successes, Dujing Pharmaceuticals embarked on a program to develop a drug that could calm the nerves and effectively treat Alzheimer's disease.

This would have been a good thing, but no one thought that it would become a test of human nature.

Many years ago, under the initiative of Ren Jianyun, Yikang Nursing Home was established, and in the name of charity and caring for the elderly living alone, it admitted a large number of homeless and childless elderly people, including many elderly people suffering from Alzheimer's disease.

And so, a plan to exterminate humanity began.

At first, the effect of the drug, although it does not treat Alzheimer's disease, is effective in calming the nerves and inhibiting the patient's hallucinations and auditory hallucinations.

But in the process of further drug development, the dead man.

After a medical diagnosis, he died of a heart attack.

The sudden death of an elderly person is nothing new, and no one cared about it at first. But the old people died one after another, which makes people can't help but associate it with the research and development of drugs.

After the accident, Ren Jianyun and Sun Jinyu sat together and began to discuss the matter.

By now, the two of them are grasshoppers on a rope.

The two found a suitable burial site in the woods behind the Yikang Nursing Home.

Later, according to the analysis of the scientific research team, it was learned that this drug has serious side effects, severe cases can instantly paralyze the heart, even if it is a professional forensic autopsy, if not carefully examined, it is difficult to find drug residues in the body, and it is likely to be characterized as sudden heart disease death.

That morning, Ren Jianyun and Sun Jinyu met and talked about who would survive after the matter was revealed.

Now, Ren Jianyun is sitting in the interrogation room, and he finally understands. After the matter is revealed, neither of them will live.

And Sun Jinyu didn't want to live for a long time, all he had to do before he died was to expose Ren Jianyun's scandal and drag him to die together.

Ren Jianyun sat on the chair with a very indifferent expression, as if he knew that this result would come sooner or later, but he sighed a little later.

The case of murder and burial in the nursing home came to an end for the time being with Ren Jianyun's confession, and the next thing to be determined is the cause of Sun Jinyu's death.

Now, all the evidence points to Ren Jianyun.

Ren Jianyun raised his head slowly, and he didn't speak, just kept smiling bitterly.

Because he never understood why Sun Jinyu wanted to expose the scandal of his nursing home, why did he blame himself for his death?

When I went that day, I didn't poison Sun Jinyu at all, why did Sun Jinyu die? Is it suicide? Or is he killing and blaming the blame?

"What, don't you admit that you poisoned Sun Jinyu?"

Lu Ke stood in front of Ren Jianyun and asked in a cold voice.

Ren Jianyun raised his head slowly, his whole face was bloodless, and he looked lifeless: "You can doubt me, but I really didn't kill him." ”

Lu Ke nodded and continued: "Sun Jinyu has participated in the operation of the nursing home and the research and development of drugs throughout the process, even if he has the channels to get the medicine, the current evidence still points to you." ”

Ren Jianyun sighed: "I understand, Sun Jinyu is dead, you must be the first to suspect me, after all, the morning of his death, we also met, and the scene was full of my fingerprints." Even if you think about it with your toes, you think of me.

For so long, I often went to Sun Jinyu's house, and I had quarrels with him, and the cleaners and neighbors had seen me and knew that we had conflicts.

Now that I think about it, Sun Jinyu is playing a big game of chess, and he has repeatedly invited me to talk about things at home, just to let me leave evidence. Then wait for the opportunity to blame me for your own death! ”

Lu Ke stared at him deadly: "So, you killed him?" ”

Ren Jianyun shook his head and looked at Lu Ke's gaze: "I said no, do you believe it?" ”

Lu Ke didn't answer his question, and instead said: "I only believe the evidence, our forensic doctor extracted a lethal drug from Hu Youming's body, which happens to be the ingredient of the drug you studied for the treatment of Alzheimer's disease. All the evidence points to you, and now the situation is very bad for you. ”

Ren Jianyun knew that he couldn't argue, but he was still trying to explain: "I really didn't kill him, Sun Jinyu can also get the medicine." ”

Lu Ke looked at him for a while, then looked away with a smile: "It's hard to say whether you believe it or not, after all, there is no conclusion yet." But I'm more interested in why Sun Jinyu is targeting you. ”

Ren Jianyun clenched his fists, his knuckles were white, and he pinched them bloodless.

couldn't help but remind him of the beginning, Sun Jinyu kept looking for things he wanted to quit......

Ren Jianyun is temporarily under criminal detention, and the murder of Sun Jinyu is still under investigation.

"Judging from the current situation, Sun Jinyu is indeed not like the ...... he killed"

In the monitoring room next to the interrogation room, Mo Yufei and Su Simeng were also discussing the case.

Mo Yufei said in a deep voice: "Judging from Ren Jianyun's current situation, killing one is also death, and killing two is also death, he has admitted so many murders in the nursing home, there is no reason not to admit Sun Jinyu's case." ”

Immediately afterwards, Lu Ke also pushed the door and walked into the monitoring room.

"Sun Jinyu is extremely likely to commit suicide, but I have never figured out one thing, why did he blame Ren Jianyun ......"

Lu Ke twisted his fingers and said in a deep voice.

Su Simon continued: "The death of his new wife made him think that all this was God's punishment, plus the matter of the nursing home, he knew that he was guilty, so he chose to die on the second anniversary of his wife's death. Then there is only one possibility for him to blame Ren Jianyun for his death, he wants to expose the matter of the nursing home. ”

Mo Yufei had a different opinion, and analyzed seriously: "If his purpose is to expose the nursing home, wouldn't it be better to call the police directly, leave a suicide note, or leave evidence?" Judging from the scene of his death, the only thing we can find is Dujing Pharmaceutical Company, which is still 108,000 miles away from the nursing home. ”

Lu Ke looked in front of the transparent one-way glass and looked into the interrogation room, and he was also thinking about these things that Mo Yufei and Su Simeng were discussing.

It's just that now, what he is thinking about more is, how did Zheng Yuxuan know about the nursing home?

Sun Jinyu talked to Zheng Yuxuan about the drug experiment before, and he also came to the conclusion that only 80% of the results of the mouse experiment were transferred to people.

Sun Jinyu died, and only the line index was directed to the pharmaceutical company.

And it was Zheng Yuxuan who led the police to the nursing home......
