My Inseparable House Guests

"I'll tell you how you murdered." Conan said to Lu Chen, "Based on the available evidence, we can infer about such a process. "Last Monday, the morning Wei Qingya died, you got up early in the morning. Maybe a small amount of sleeping pills was put into Wei Qingya's water, causing Wei Qingya to sleep all the time.After all this is done, you go to the birthday party of your classmates, and at noon you find a time when others are not paying attention, and then you return home. At this time, Wei Qingya has not yet woken up."

"You plugged a silver needle into Wei Qingya's chest after powering on, and when it was estimated that she was not saved, you pulled out the silver needle. After the needle was pulled out, no trace was visible on the body surface, and then you returned again. party, and take the silver needle away and dispose of it when you leave. Wait until night to go home."

Conan said with his finger Lu Chen, "And after you got off work, Wei Qingya was not even dead, so you sent her to the hospital for emergency treatment, because Wei Qingya has always had a bad heart, and the needle hole of a silver needle has changed. I can’t see it, so Wei Qingya was diagnosed with myocardial infarction of course. Logically speaking, your plan should be perfect, but you think no one can see it, so you dare to agree to Wei Qingya’s last wish in front of her to save the body. It was handed over to the school to make specimens, but you never thought that Fang Zege saw black blood in Wei Qingya’s pericardial cavity, and then that small pinhole was soaked in formalin. After being enlarged, we have the most critical evidence."

"It's really hard to make up a story for your kid." After hearing Conan's words, Lu Chen's face was still very calm, as calm as he used to practice killing mice in the laboratory.

"According to you, I caused Wei Qingya's myocardial infarction?"

"That's right." Fang Ze interjected at this time. "Since four years ago, you have mixed anti-arrhythmic drugs in the water or food that Teacher Qingya usually drinks, which caused the heart of Teacher Qingya to suddenly become uncomfortable. Then you spread the bad things about Teacher Qingya's heart in school, so that everyone has a first impression and prepares for your murder in four years."

"Yes." Conan continued, "As a medical student who studied hard in college, you are absolutely accurate in the dose. The anti-arrhythmic drugs you gave Wei Qingya only made Wei Qingya's heart not Comfortable, but it will not lead to death, so after four years of laying your grounds, your murder will not be suspicious."

"It's ridiculous." Lu Chen said, "I bought four years of anti-arrhythmic drugs, including the previous sleeping pills. These drugs are all prescription drugs, and the purchase will be recorded. Haven't the police checked my purchase records before? I never bought this medicine."

"No, you bought it." Conan continued. "There are anti-arrhythmic drugs and sleeping pills on the Pfizer Clinic where you work. As the only doctor in the clinic, you take some without leaving any records. Medicine is really easy, but in fact, there is no need to check the records four years ago. We only need to check the last time Wei Qingya went to the doctor because of an uncomfortable heart. Check the clinic’s accounts according to the time. I can find that there are some anti-arrhythmic drugs that cannot be purchased at all, because their purchaser is you!"

Lu Chen’s calm face began to panic. Indeed, the surveillance video from the community to the pinhole in Wei Qingya’s heart and then to the Pfizer Clinic who could not find the purchaser’s drugs, these three pieces of evidence were taken out separately. I can't be sure that he is the murderer, but the problem now is that these three pieces of evidence appear at the same time, and he has no chance of coming back!

Ruined.

Lu Chen originally thought that what he was doing was perfect, so he dared to give Wei Qingya's body to the school to make a rough specimen, but he didn't think it was a hundred secrets.

It was just because of a simple black blood in the pericardial cavity that attracted Fang Ze's attention.

Lu Chen sat on the ground paralyzed, stretched out his hands tremblingly, and said to the policemen present, "I admit that I am guilty. It was I who killed Wei Qingya. Isn't it counted as surrendering me like this? Can I win a favor? Faintly."

Several people around the serious case team saw Lu Chen doing this and immediately took out the handcuffs, handcuffed Lu Chen, and picked him up.

"Can you take it lightly? It depends on the court, not us." The Fang team glanced at the top medical student here, turned his head, and looked at Conan with interest.

"Children, can you tell me the motive of this guy? If this guy just broke up with his wife and wanted a divorce, he wouldn't have spent four years designing a murder case. After all, it's not before. Divorce is a normal thing, and both of them are still young."

The voice of the serious case team fell, and everyone else in the guard room also looked at Conan, wanting to hear how this magical elementary school student explained this matter.

But Lu Chen raised his head, hoping that Conan would not continue speaking, "Please stop talking, leave me something that I can confess, I still want to relax."

Conan ignored him, but continued, "Previously, Fang Ze and I thought it was Lu Chen who had a love outside. Only then will we tear off the wedding photos of the two immediately after the death of our wife, and the house Give it away, we also regarded this as important evidence when we first reported the crime."

Fang Ze paused. Everyone was fascinated and wanted to let him continue, but Conan suddenly said, "I'm a little thirsty, do uncles have water?"

"Yes." A civil aviation policeman hurried over and gave Conan a bottle of mineral water, and thoughtfully unscrewed the bottle before handing it to Conan.

Conan took a few sips from the water bottle and continued, "But we soon discovered that this theory is untenable, because if it’s just a lover, why did the couple stay for four years? There hasn’t been even one conflict here. Moreover, in the marriage crisis between Wei Qingya and Lu Chen four years ago, her mother only mentioned that Lu Chen wanted to divorce, but did not mention that Lu Chen was outside. There is something for the junior."

Conan looked at Lu Chen who had been handcuffed and continued, "Besides, if Lu Chen really has a lover, then when he goes abroad today, he will definitely be a lover, not alone. ."

"So why did he kill Wei Qingya?" a civil aviation policeman asked impatiently.
