"How did you kill ......" Luna showed an almost poignant smile, such a smile Sunan had seen before, it was the first time she appeared in the city bureau and told her that she was killed.

That's how she laughed then, but this time it was almost crazy.

"In this society, it is difficult to let a person live...... she looked at Su Nan and Xu Zirui motionlessly: "There will always be sudden accidents, and there will always be incurable serious diseases!" But if you want to kill a person, it's very simple, in terms of the means of killing, if I talk about it one by one, it will be a bit of an axe, you are a policeman, what kind of killing methods have you never seen? Especially Officer Xu, who has been engaged in criminal investigation for many years, you should have a lot of experience, right? ”

Xu Zirui didn't answer her, but just reminded her: "Let's talk about the point." ”

"My focus is ...... If you want to kill someone, wouldn't it be easy? I believe that your anti-reconnaissance ability will make it impossible for others to find you, the murderer, forever! ”

After speaking, he laughed to himself, and waited for Xu Zirui to get angry with a good show.

He did feel that the anger was big, but the anger was not directed at her, but at Su Nan: "This is the result of your arraignment last night?" Your so-called truth is for me to waste my time here listening to her nonsense? ”

"People are dying, just kidding, Officer Xu, don't have such a big temper, this kind of bad temper is not easy to find a girlfriend."

"Shut up!" Xu Zirui scolded, and she immediately raised her hand to surrender.

Su Nan pinched the bridge of his nose a little tiredly: "Don't worry, even if you are convicted today, you won't be able to die for a while, and you will be confessed to all those who should be confessed, and strive for leniency." ”

"Can I still be lenient? I have been condemned to death by heaven. Luna sighed lowly, "Officer Xu, I'm sorry, but in order not to waste your precious time, let's get back to business. ”

"If you don't waste time, you should be done by now!"

Tucking her sideburns behind her ears, Luna is described as withered at this time, but her movements and demeanor have a grace that belongs to a celebrity.

"Lin Juan's death started with Song Ming, who himself had a certain mental illness and had been taking antidepressant drugs. Coincidentally, at a project investment meeting, I learned about a fungus called ergotine virus, and I have been interested in research and clinical trials in this area, so I wanted to try it myself. ”

"Be specific." Su Nan said mercilessly: "What meeting, who invited you, just to pay attention?" Didn't participate and buy? ”

"I forgot the name of the meeting, in Southeast Asia, Officer Su, you shouldn't be able to control that, besides, this matter doesn't seem to have anything to do with this case. At first, I was really just paying attention, and then I bought domestic research, and Song Ming was the first experiment in China. ”

"Experiments?" Su Nan couldn't help but slap the table: "A human life was so easily said by you to be an experiment?" I think the real person with mental illness is you! ”

Luna laughed bitterly and said in a low voice, "That's right, I'm thinking, I'm sick too, I should have experimented with myself in the first place...... But even if I use myself as an experiment, I will kill Song Ming and Lin Juan. ”

Xu Zirui said: "Can the ergot virus really control people's thinking and brain? At your mercy? ”

"Hahaha! Officer Xu, you have been engaged in the criminal investigation profession for many years, and you believe all the rumors on the Internet? Luna smiled and shook her head, laughing like she was crying: "If there really is, I will be the first to use it on Su Chen's body!" And on you! You say, should I use it in the bank, so that I can have a lot of money and not be at the mercy of others! You can be with Su Chen! Don't you say? ”

He was still laughing maniacally, and tears flowed from his eyes while laughing.

Su Nan quietly watched her vent her emotions, and when she was almost done, she said indifferently again: "You continue." ”

The handcuffed hands wiped her face, and Luna laughed, "Go on what?" Oh, the ergot virus ...... This thing stimulates the central nervous system, and he also takes sleeping drugs, which is enough to produce chronic poisons that slowly accumulate in the body. ”

Xu Zirui looked at him indifferently and said coldly: "How did you poison the deceased Song Ming?" ”

Suna glanced at him: "She hasn't said this yet. ”

"It's okay, it's okay," Luna said, "Are you going to ask me if Su Chen knows?" I can tell you unequivocally, he doesn't know, he doesn't know anything. If Su Chen had known, he would definitely not have let me do it. Although he would not let me do such a thing for the sake of his own future, I believe that he also loves me, and always advises me not to do anything out of line, he is afraid of me, afraid that I have human blood on my hands, and that I will go on a road of no turning back in the future. ”

Su Nan couldn't help but glance at her more, and some words came to her lips and stopped, if she knew that all her criminal suspicions during this time were arranged by Su Chen before he was imprisoned, I don't know what kind of mood she would feel after saying these words today.

"Tell me when and how you poisoned yourself."

"I remember the time very well...... At the end of the year, Su Chen wanted to give a gift to his future father-in-law, and I gave him a five-grain health meal mixed with ergot virus, and asked him to specially tell his father-in-law to eat every day, and that box was enough for him to eat for a few months. ”

"Su Chen didn't know when you gave it?"

"Of course I don't know, you think I'm stupid enough to tell him about this kind of thing?"

Su Nan said, "Senior brother, what else do you want to ask?" ”

"It's gone."

"Okay, then you can continue to talk about how you used drugs to kill Lin Juan and Song Ming."

"Didn't I say that this fungus has a certain stimulating effect, which is very harmful to the nerves, and after taking sleeping pills, it can not only be converted into toxins and accumulate in the body, but also make people's nerves excited, become irritable and irritable, and uncontrolled behavior is more extreme. In this case, as long as there is a little stimulation from the outside world, it can evolve into an irreparable result, presumably Lin Juan had argued with him about something that day, so he killed someone in a fit of anger. ”

Su Nan sat down quickly in his notebook and said without raising his head: "How do you know that the person he can kill must be Lin Juan, and there is a woman living with them." ”

"You mean Song Yafei? Officer Su, I don't know if he can kill Lin Juan, after all, this thing can't really control people's minds. In fact, even if it is Song Yafei who kills, I don't care, anyway, their family has to die. ”

He said these words calmly without changing his face, but it didn't look like he had killed someone for the first time, but it looked like he had killed people many times.

Su Nan pinched the bridge of her nose, the air in the interrogation room was too oppressive for her.

"So, Lin Juan was indeed killed by her husband Song Ming?" Xu Zirui checked with her.

"Isn't that what you checked?" Luna asked him rhetorically.

Xu Zirui didn't speak, the results of their investigation were very close to this answer, but because there were only three people in the house at that time, two were dead, and one Song Yafei was completely unaware, so whether Song Ming killed him could only be proved by physical evidence.

Today, it is also a way for Luna to confess these things, and to get answers from another angle.

"Song Ming's death was because of the ergot virus?"

"Ergot and sleeping pills, what are the results of your autopsy? Don't have a lot of sleeping pills left in your stomach? ”

Su Nan said: "No, after his wife died, he may have also been aware of it, suspecting that the medicine he took might bring mental side effects, so he didn't take any medicine with him after moving out, including sleeping pills." ”

"Yo, he's still a very particular old man," Luna sneered: "But no matter how particular he is, he is not guarded against Su Chen, and he can't imagine that the really poisonous thing is in the health meal sent by his future son-in-law." ”

Xu Zirui frowned again, and almost knocked on the table: "Tell me well, what the hell is going on, how did Song Ming die." ”

"How did you die...... It's very simple, you know that Song Ming has had a mental illness for a long time, and long-term medication has produced dependence. Coupled with the fact that he killed his wife with his own hands, the mental pressure increased but the maintenance of the drug was cut off, this matter is put on anyone, I'm afraid he won't live long, right? Especially for someone like him in a high position, the pressure goes without saying. ”

Although what is said is true, a person will not be inexplicably 'crushed' to death because of depression and mental pressure, right?

"So, are you sure it has nothing to do with the ergot virus?"

"I'm not sure, but what I know for sure is that the sleeping pills plus ergot line murder didn't happen, and I thought he would increase the dose of sleeping pills after this incident and push him to see his wife as soon as possible, but I didn't expect it to drag on for more than a month."

Su Nan suddenly thought of something, and turned to the little policeman standing at the door and said: "Go to the archives room, find out Song Ming's files before his death, and focus on his psychiatrist." ”

"Yes!" The little policeman said yes and hurried away.

"Although the case is reasoning, the result is not far from ten." Luna took a deep breath, as if relieved.

Su Nan turned his head to look at Xu Zirui, who had a calm expression, but frowned deeply: "It's useless for you to see me, before the investigation results come out, Su Chen's suspicion cannot be washed away, after all, he has sufficient criminal suspicions." ”

"Just because he's Song Yafei's boyfriend?" Luna smiled: "Don't be funny, who is Su Chen, wandering in City A without a father and mother, only I can help him, but there is only a limit to what I can help." But it's different to find a rich and powerful girlfriend, his father-in-law will arrange all his future. ”

Su Nan sneered and turned his pen: "I believe that in the nightclub where Su Chen works, there are countless rich daughters who played in the past, why did he choose Song Yafei?" ”

"This may be fate, in the vast sea of people, meet the right person, this is fate." Luna looked at Su Nan with a playful expression: "It's a pity that you haven't met this person, and you can't understand that kind of mood." ”

Su Nan didn't hear the second half of her sentence, and sneered back: "The reason why he chose Song Yafei is to borrow your hand to kill people." ”
