Chapter 11

"I'll tell you how you killed people." Conan said to Lu Chen, "Based on the existing evidence, we can infer such a process, "Last Monday, that is, the morning of Wei Qingya's death, you got up early in the morning and probably put a small amount of sleeping pills in Wei Qingya's water, which led to Wei Qingya sleeping all the time. After all this, you went to the classmate's birthday party and returned home at noon when others didn't pay attention, but Wei Qingya didn't wake up at this time“

"You plug a silver needle into Wei Qingya's chest after powering it on. When it is estimated that she is hopeless, pull out the silver needle. After pulling out the needle, there is no trace on the body surface. Then you return to the party again, and take away the silver needle when you leave. Wait until the evening to go home."

Conan pointed to 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 a bad heart all the time, and the needle hole of a silver needle could not be seen by the naked eye, Wei Qingya was naturally diagnosed as myocardial infarction. Logically, your plan should be perfect to perfection, but you thought that no one could see it, so you dared to agree to Wei Qingya's last wish and handed over the body to the school It was made into a specimen, but you never expected that first Fang zege saw black blood accumulation in Wei Qingya's pericardial cavity, and then that small pinhole was enlarged after being soaked in formalin, which gave us the most critical evidence. "

"It's really difficult to make up stories for your child." Lu Chen listened to Conan's words, and his face was still very calm, just as he used to practice killing mice in the laboratory.

"According to you, I also caused Wei Qingya's heart block?"

"That's right." Fang Ze interjected at this time, "since four years ago, you have adulterated antiarrhythmic drugs into the water or food that teacher Qingya usually drinks, which has led to teacher Qingya's heart suddenly uncomfortable. Then you spread the bad news about teacher Qingya's heart wantonly in the school, so that everyone has a first impression and prepare for your murder four years later."

"Yes." Conan then said, "as a medical student who studied hard in college, your grasp of the dose is absolutely accurate. The antiarrhythmic drugs you gave Wei Qingya just made Wei Qingya's heart uncomfortable, but it won't lead to death, so after you paved the way for four years, your murder will not be suspected."

"Ridiculous." Lu Chen said, "I have bought antiarrhythmic drugs for four years, including previous sleeping pills. These drugs are prescription drugs, and the purchase will be recorded. Didn't the police check my purchase records before, and I didn't buy this drug at all."

"No, you did." Conan continued, "There are antiarrhythmic drugs and sleeping pills on the medicine rack of Pfizer clinic where you work. As the only doctor in the clinic, it's too easy to take some drugs without leaving any records, but in fact, we don't need to check the records of four years ago. We just need to check the last time Wei Qingya went to the hospital because of heart discomfort. According to the time, we can find out that there are some antiarrhythmic drugs by checking the accounts of the clinic There is no buyer at all, because their buyer is you! "

Lu Chen's calm face began to appear flustered. Indeed, the surveillance video of the community, the pinhole in Wei Qingya's heart, and the drugs that can't find the buyer in Pfizer clinic. No matter which of these three evidences is taken out alone, it can't be sure that he is the murderer, but the problem now is that these three evidences appear at the same time, and he has no chance to overturn!

It's over.

Lu Chen originally thought that what he did was flawless. Only then did he dare to boldly hand over Wei Qingya's body to the school to make a general specimen, but he didn't expect it to be a secret.

Just because a simple black blood in pericardium cavity attracted Fang Ze's attention. If Conan doesn't come, Fang Ze alone can't think of all this and find it out, but he happened to meet Conan, who is dead and solves cases every day.

Lu Chen slumped on the ground, stretched out his hands tremblingly, and said to the policemen present, "I admit that I'm guilty. I killed Wei Qingya. Is this my surrender? Can I fight for a lighter sentence?"

Seeing Lu Chen doing this, several people around the serious case team immediately took out handcuffs, cuffed Lu Chen and lifted him up.

"Whether we can get off lightly depends on the court, not on us." The team glanced at the medical talents here, turned around and looked at Conan with great interest.

"Little friend, can you tell me about this guy's motive? If this guy just broke up with his wife and wanted to divorce, but he didn't need to spend four years designing a murder case. After all, now is not the past. Divorce is a very 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 the magical pupil explained this matter.

Lu Chen raised his head, hoping that Conan would not continue to say, "please stop talking and leave me something to explain. I still want to take it easy."

Conan ignored him, but continued, "before, Fang Ze and I always thought it was Lu Chen who had an affair outside. This is why after his wife died, we immediately tore up their wedding photos and gave the house away. We also took this as important evidence when we first reported the case."

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

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

Conan took a few sips of the water bottle and continued, "But we soon found that this theory was untenable, because if it was just love and people, why did the couple not have even one conflict in four years? Moreover, Wei Qingya only mentioned Lu Chen's desire for divorce in her mother's conversation four years ago, but did not mention Lu Chen's little three outside."

Conan looked at Lu Chen, who had been handcuffed, and continued, "besides, if Lu Chen really had love. People, then when he went abroad today, he must also have love. People, not alone."

"So why on earth did he kill Wei Qingya?" A civil aviation policeman couldn't wait to ask.
