The figure who rushed into the floor was a middle-aged man who looked a little embarrassed, with a pair of handcuffs in his hands. Obviously, it was not as simple as an ordinary person.

After entering the floor, the middle-aged man glanced around, and then immediately ran to the stairs behind Conan and others, as if he was avoiding something.

However, when he ran to bu Mei, officer Sato with a police gun also ran up from downstairs.

Seeing Conan and others, officer Sato's face changed. He immediately pointed his gun at the middle-aged man and ordered: "Dongtian, stop, raise your hands immediately and stand still, otherwise I'll shoot."

After hearing officer Sato's cry, the middle-aged man named Dongtian stopped. His face changed and seemed to be making some very difficult choice.

After a moment of hesitation, Dongtian's face showed a firm intention. Then he grabbed Bu Mei who stood beside him and threatened, "don't come here, let me go!"

"Damn it!"

Considering the safety of Bu Mei, officer Sato had to put away his pistol, follow behind Dongtian and run to the roof of the abandoned building.

Dongtian didn't hurt Bumei. He put Bumei in the stairs leading to the roof, and used a ladder on the roof as a pedal to escape to another building next door.

When Sergeant Sato chased to the roof, Dongtian had successfully climbed to the roof of the next building, threw the ladder as a passage downstairs and escaped into the next building from the stairs.

Officer Sato didn't want to let Dongtian escape. He used the iron rainwater pipe of the abandoned building as a traction rope, successfully fell into the stair platform on the side of the next building, entered the next building and continued to pursue Dongtian.

Before long, officer Sato caught up with Dongtian, knocked Dongtian down in the men's toilet and handcuffed Dongtian with himself to prevent him from continuing to find a chance to escape.

However, when officer Sato handcuffed the handcuffs, he found that Dongtian's arm accidentally passed through the sewer pipe in the toilet. There was an iron pipe between them.

"No... where's my key..."

Officer Sato looked bitter and found that the key was left in the drawer of the office, that is, she and Dongtian were trapped in the toilet.

Fortunately, Sergeant Sato didn't perform the task alone. Soon, Sergeant Takagi and Conan arrived here together.

……

"Well, I see. I'll be there right away."

Bai yanzhenyu, who originally wrote in Maori office, suddenly received a call from Conan, so he came to the trapped building of police officer Sato according to the address given by Conan, and saw Conan and his party in the toilet.

After hearing speechless Conan's story, Shii Masawa looked at Sato police officer and Gao Mu police officer, Tucao way: "that is to say, you first make complaints about the murderer escorted, and then you are trapped in the chase process?"

Sergeant Sato nodded with shame and then asked, "brother Baiyan, listen to Conan that you have a way to unlock the lock, so please help open the handcuffs. If you don't go back, there will be a riot in the police department."

"Sorry, Conan didn't tell me clearly on the phone. I don't have tools in my hand for the time being..."

Baiyan Zhenyu stood up and suggested, "why don't you let officer Gaomu go back to your office to get the key? Anyway, the prisoner is here and can't run away."

"No, if the colleagues in the first search class knew it, they would laugh at me." officer Sato, who loves face, obviously didn't want it to be known by other officers.

"Then you can only wait for me to go back to get the tools and help you unlock the lock." Bai yanzhenyu said no more and was ready to go back to get the tools to help officer Sato unlock the lock.

Just then, Dongtian suddenly collapsed and shouted, "in fact, I'm innocent. I didn't kill anyone at all. Please believe me..."

"Dongtian, stop sophistry." officer Sato looked at Dongtian impatiently and didn't believe what he said.

Dongtian's eyes were dark, but he stubbornly explained, "the prisoner is really not me. I don't know what's going on. I got up early in the morning and miss murashi was dead. Please believe me."

Baiyan Zhenyu stopped and asked curiously, "officer Gaomu, what case is this?"

"Well, there was a murder case two days ago. The one who died was Miss Murakami Zhenmei, who lived in the same apartment as Mr. Dongtian, and she was also the boss of his company."

Looking at the unknown Bai Yan Zhenyu and others, officer Gaomu explained: "the scene of the crime was the bathroom in Miss murashi's room, and when she was found strangled in the bathroom, Mr. Dongtian lay drunk on her bed to sleep."

"The door lock and chain of the gate are all locked, which is equivalent to a secret room. In addition, Mr. Dongtian's fingerprints can be collected from the handle, key, chain of the gate, murder weapon wrapped around the neck of the body and video recorder wiring."

"According to our investigation, Mr. Dongtian often had conflicts with her at work, and not long before the crime, Mr. Dongtian excitedly told his friends in the tavern that we must teach miss murashi a lesson..."

"I think he accidentally came to miss Murakami's room when he was drunk. After a dispute, he killed Miss Murakami under the stimulation of alcohol."

After officer Takagi explained the situation of the case, officer Sato added: "the reason why you locked it was that you didn't want her to escape. After killing her, you fell asleep on her bed because you couldn't drink."

"I really don't remember all the things that night..."

In the face of the evidence spoken by police officer Takagi and police officer Takagi, Dongtian seemed very lost, but he still didn't give up his defense and denied: "you're right. I really hate her because she often makes trouble for me, but it's not enough to kill her."

"In that case, would you like to go back to the police station with us and explain clearly?"

Officer Sato looked at Dongtian angrily and asked, "if the murderer is really not you, we will release you. Why should we run away?"

"Because I have to go to Chicago to attend my daughter's wedding."

Dongtian's tone was very firm and explained: "since I divorced my ex-wife, she has been raised by my ex-wife. I thought my daughter had hated me in the past 17 years, but I didn't expect that she sent me a wedding invitation some time ago. You say, how can I not participate in such an important activity!"
