In the detention house.

Lu Zhengbei reluctantly came to the detention center, gave the food Wan Yuchun asked for, and then drove back to the old house.

Wan Yuchun opened the food box sent by Lu Zhengbei and saw the food with good color and flavor. He immediately picked up his chopsticks and ate it.

However, she was just half eaten when she suddenly vomited violently. There was also bleeding in her mouth, nose and external auditory canal. She screamed and fainted.

The police rushed Wan Yuchun to the hospital and pushed into the rescue room.

For a long time, the doctor came out of the emergency room, took off his mask, and sighed, "well, we tried our best. The patient is too poisoned to be rescued."

"What poison did she get?" the policeman asked in a tight voice

"Arsenic trioxide, commonly known as" arsenic. " The doctor replied word by word.

After a careful investigation, the police found that Wan Yuchun's soup was faulty, and the arsenic dose detected in the soup was enough to kill.

It can be concluded that the person who sent the food was suspected of committing a major crime, and the police immediately listed Lu Zhengbei as the first suspect.

Three policemen drove to the old residence of Lu family and quickly walked to the bedroom where Lu Zhengbei lived. The leading policeman said solemnly: "there is sufficient evidence to prove that you are related to the murder of Wan Yuchun. Please go to the police station with us."

Hearing this, Lu Zhengbei felt like a thunderbolt on his head. He stood at a loss and forgot to speak for a moment.

The sound of metal impact brought by handcuffs pulled Lu Zhengbei's free mind back. He asked in a puzzled way: "Wan Yuchun is dead? I was fine when I saw her just now

"The dead was poisoned and died after being sent to the hospital because of ineffective rescue." The policeman explained without expression, glanced at Lu Zhengbei and said coldly, "the poison was found in the soup you sent, so you are the most suspect. Lu Zhengbei, please cooperate with us in the investigation. "

"Her death has nothing to do with me!" Lu Zhengbei was eager to prove his innocence, so he sped up his speech. "Wan Yuchun asked me to give her something to eat, so I asked the servant to cook the food, and then I took it directly to the detention center. I never touched that thing all the way."

Lu Zhengbei was very confused. He really hoped that Wan Yuchun would disappear, so that he would not have to marry her.

However, this is just thinking, never thought to put into action, killing is a heinous crime, he has not played enough, how can he take the initiative to jump into the fire pit?

Someone must be playing tricks on this matter, but that person is definitely not himself!

However, no matter how he explained it, the police thought he was sophistry and did not believe what he said.

"Lu Zhengbei, if you don't do it, we'll give you a clean answer."

The patience of the police had been exhausted by him and he could not help but put handcuffs on him. One of the policemen took him to the police car and took him to the police station.

The Lu family heard that Lu Zhengbei had been taken away by the police. They rushed back from the outside and gathered in the living room of the old house.

The chief policeman ordered his colleagues to find the surveillance video, and he began to cross examine the master and servant of the Lu family.

The first one to be questioned was the servant who made soup for WAN Yuchun. She knew that she was scared to death after the incident, so that she was in a state of half stupidity and half stupidity like being shocked.

The police called her several times, and the servant came back to her senses and said, "Comrade police, I swear, I haven't done anything."

"Don't be afraid. We won't injustice any good people." The tone of the policeman softened a little, his eyes were shining and he said, "tell me about the process of making soup."

After swallowing, the servant said seriously, "as usual, I first prepare all the ingredients, and then put them together in the soup pot. Then I pour water into the pot, close the lid, set the fire, and then start to cook the soup. After a while, when the soup is ready, I give it directly to the third young master. "

The policeman frowned and thought for a while, and then asked in a tight voice, "what's the difference between the ingredients you use and what you usually use? For example, have you changed the channel of purchase? "

"No! There's no difference between the ingredients and what you usually use. " The servant answered with great certainty.

The police did not find any valuable clues from the servant, so they asked the servants who often went into and out of the kitchen. They found that the testimony of all the servants was basically the same, and it was impossible to see who would attack the food.

Then, the police interrogated Lu's family, who were almost all trying to justify the suspect. They repeatedly stressed that Wan Yuchun was Lu Zhengbei's fiancee and that he had no reason to kill her.

Later, the police carefully watched the surveillance video several times with doubts, proving that the servant did not add any special "ingredients" to the soup. The process and ingredients used in the soup were consistent with what she described.

The police from the forensic science department rushed to Lu's old house and examined the ingredients in the kitchen, but they found no poison in the ingredients.

After some twists and turns, the police came to a conclusion: the poison was not put into the soup in the process of making. Then, there is only one possibility for this homicide case, that is, Lu Zhengbei poisoned the food on the way.At that time, when he was alone in the car, he had both the time and the conditions to commit the crime.

As for the fact that Wan Yuchun is his fiancee, it does not mean that he has no motive to commit the crime. Let alone killing his fiancee, even the murder of a genuine wife is not uncommon.

Even if there is any evidence in front of his family, nailu will tell his family the result of the investigation.

After the police left, Mr. Lu walked up and down in the living room with a gloomy face. The deep eyebrows gathered together to form a deep character of Sichuan.

Zhou Qiuyue was so sad that she cried: "Dad, I know my son. It's impossible for Zhengbei to kill anyone!"

Mr. Lu gave her a dignified look and sighed: "I hope he is not the murderer, but the police don't believe it. Well, what can I do? "

When Zhou Qiuyue heard this, she cried even more, so that she couldn't say a word.

Mr. Lu's facial features were still tight, and he sighed several times in succession. It seemed that his eyebrows were full of anxiety.

For a long time, after receiving the news, Lu Zhengqing and Tang Mengyu rushed back to the old house of the Lu family, and went straight to the room of Mr. Lu to inquire about the situation.

"Grandfather, what's the result of the investigation?" Lu Zhengqing asked eagerly.

Mr. Lu frowned and shook his head. He said gloomily: "at present, all the evidence points to the north. The situation is very unfavorable to him. The police think that he is the person who poisoned the drugs."

Tang Mengyu smell speech, beautiful eyebrows frown, open his mouth said: "with my understanding of him, it is unlikely to do such a thing."
