"I'll tell you how you killed someone." Conan said to Lu Chen. "Based on the available evidence, we can infer a process like this. "Last Monday, that is, the morning of Wei Qingya's death, you got up early and soon Maybe a small amount of sleeping pills were put into Wei Qingya's water, causing Wei Qingya to sleep all the time. After doing all this, you went to your classmate's birthday party and returned home at noon when no one else was paying attention. Wei Qingya hadn't woken up yet. "
"You energized a silver needle and inserted it into Wei Qingya's chest. When it was estimated that she could not be saved, you pulled out the silver needle. After the needle was pulled out, no traces were 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 before going home."
Conan pointed his finger at Lu Chen and said, "After you got off work, Wei Qingya was not even dead, so you sent her to the hospital for rescue, because Wei Qingya had always had a bad heart, and the pinhole of a silver needle was visible to the naked eye. You couldn't see it, so Wei Qingya was naturally diagnosed with a myocardial infarction. Logically speaking, your plan should be perfect, but you thought that no one could see it, so you dared to agree to Wei Qingya's last wish and leave the body. It was handed over to the school for specimen preparation, but you never expected that first Brother Fang Ze saw black blood in Wei Qingya's pericardial cavity, and then, the small pinhole was soaked in formalin. It was then amplified, allowing us to grasp the most critical evidence.”
"It's really hard to make up stories for a kid like you." After listening to Conan's words, Lu Chen's face was still very calm, just like when he used to practice killing mice in the laboratory.
"According to what you said, Wei Qingya's heart attack was also caused by me?"
"That's right." Fang Ze interrupted at this time, "Since four years ago, you have mixed anti-arrhythmia drugs into the water or food that Teacher Qingya usually drinks, which caused Teacher Qingya's heart to suddenly feel uncomfortable. , and then you widely spread the news about Teacher Qingya’s bad heart in the school, giving everyone a preconceived impression and preparing for your murder four years later.”
"Yes." Conan continued, "As a medical student who studied hard in college, you were absolutely accurate in the dosage. The anti-arrhythmia drug you gave Wei Qingya only made Wei Qingya's heart unstable. It’s comfortable, but it won’t lead to death, so after you’ve been laying the groundwork for four years, your murder will not arouse suspicion.”
"It's ridiculous." Lu Chen said, "I have bought anti-cardiac drugs for four years, including sleeping pills. These drugs are all prescription drugs, and the purchases are recorded. Didn't the police check my purchase records before? I have never purchased this drug at all."
"No, you bought it." Conan continued, "There are anti-arrhythmia drugs and sleeping pills on the medicine shelf of the Pfizer clinic where you work. As the only doctor in the clinic, you took some without leaving any records. The medicine is too easy, but in fact, we don’t need to check the records from four years ago. We only need to check the last time Wei Qingya went to the doctor because of heart discomfort, and check the clinic’s accounts based on the time. It can be found that some anti-arrhythmia drugs cannot find buyers at all, because their buyer is you!"
Lu Chen's calm face began to show panic. Indeed, no matter which one of these three pieces of evidence was taken out individually, from the surveillance video of the community to the pinhole in Wei Qingya's heart to the drugs at the Pfizer clinic whose purchaser could not be found, It's not certain that he is the murderer, but the problem now is that with these three pieces of evidence appearing at the same time, he has no chance of making a comeback!
Ruined.
Lu Chen originally thought that what he did was flawless, so he boldly handed Wei Qingya's body to the school to make a rough specimen, but he didn't expect it.
It was just a simple black blood in the pericardial cavity that caught Fang Ze's attention. And if Conan hadn't come, Fang Ze alone wouldn't have been able to think of all this and find it out, but he happened to encounter Conan who was surrounded by dead people every day and solved crimes every day.
Lu Chen collapsed on the ground, stretched out his hands tremblingly, and said to the police officers present, "I admit that I am guilty. I was the one who killed Wei Qingya. Does this count as surrendering? Can I get a prison sentence?" Easily."
When several people from the Crime Team saw Lu Chen like this, they immediately took out the handcuffs, cuffed Lu Chen, and picked him up.
"Whether the sentence can be given lightly depends on the court, not on us." Team Fang 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's crime? If this guy just broke up with his wife and wanted a divorce, he doesn't have to spend four years designing a murder case. After all, this is not the past. Divorce is a normal thing, and both of them are still young."
After the serious crime team finished speaking, everyone else in the guard room looked at Conan, wanting to hear how this magical primary school student would explain this matter.
But Lu Chen raised his head, hoping that Conan would stop talking, "Please stop talking and leave me something to explain. I still want to be given a lighter sentence."
Conan ignored him and continued, "Before, Fang Ze and I always thought that Lu Chen had a lover outside. That's why after his wife died, we immediately tore up their wedding photos and destroyed the house. To give it away, we also regarded this as important evidence when we first reported the crime."
Fang Ze paused for a moment. Everyone was listening intently and wanted to let him continue, but Conan suddenly said, "I'm a little thirsty. Uncles, do you have any water?"
"Yes, yes." A civil aviation policeman came over quickly 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 was untenable, because if they just had a lover, then why did the couple stay together for four years? There has not been a single conflict in the family. Moreover, during the marriage crisis with Lu Chen four years ago, Wei Qingya only mentioned that Lu Chen wanted a divorce when talking to her mother, but she did not mention that Lu Chen was outside at all. There is something about the mistress.”
Conan looked at the handcuffed Lu Chen and continued, "Besides, if Lu Chen really has a lover, then when he goes abroad today, he will definitely take his lover with him instead of alone. .”
"So why did he want to kill Wei Qingya?" a civil aviation police officer asked impatiently.
