"Ah!"

Everyone was startled by the sudden accident. Xiaolan, Yuanshan and ye screamed in horror.

Baiyan Zhenyu, Conan and Pingci of the kimono department were used to this scene for a long time. Without any fear, they immediately ran to check the situation.

Baiyan Zhenyu did not check the body for the first time, but looked up to ensure that there were no other falling objects threatening the safety of everyone.

However, to his surprise, there was a figure on the edge of the roof of the tall building where the body fell, lying on the railing and looking down.

"There's someone up there!"

Baiyan Zhenyu reminded them that after a word, he ran to the roof of the building first. Conan and the kimono Department arranged for officer Sakata, who was responsible for driving, to call the police and followed him.

Baiyan Zhenyu's physical quality was strong, and he used skills similar to Parkour. He soon reached the roof and saw the yellow man looking down.

Looking at the man in yellow who turned around when he heard the news, Bai Yan Zhenyu's face sank and asked, "did you push that man down?"

"No... I didn't do it."

The man in yellow flustered waved his hand and explained, "I'm the manager of the coffee shop on the second floor. Someone called me and said there was a strange man on the roof, so I came up to see the situation. As a result, I heard a scream downstairs. Then I lay down on the railing to see what happened downstairs."

"Oh? Really?" Bai yanzhenyu didn't believe his one-sided words. He stared at each other's eyes and tried to see something from it.

"Really, this is my business card. If you don't believe it, you can ask my clerk." the man in yellow took out a business card and handed it to Bai Yan Zhenyu, which proved his identity, but he couldn't clear his suspicion of crime.

"In that case, please go downstairs with us to meet the police."

Baiyan Zhenyu's suspicion weakened slightly. After searching the roof with the service department, they returned downstairs with the suspect.

Before the police arrived at the scene, Bai yanzhenyu and others were not idle and began to check the body that fell on the front hood.

The victim was a middle-aged man with a rope tied around his waist, a knife inserted in his chest, and a black wallet between the knife and his chest.

Judging from the stiffness of the body and the blood coagulation at the wound, the time of death was at least one day ago, and the cause of death was not a knife inserted in the chest, but strangled by someone.

After checking the situation of the body, Bai yanzhenyu pointed to the rope on the deceased's waist and speculated: "it seems that the uncle didn't lie. If he tied a knot on it and got stuck in the door leading to the roof, as long as the uncle pushed the door open, the body would fall down."

Officer Sakata looked at the roof above and the body. He asked, "but how could he fall into the patrol car?"

"It should be just a coincidence," said Hattori, touching his chin thoughtfully. "But I think it should be a punishment for someone?"

"Er... Service department, what punishment?" Bai Yan Zhenyu was stunned when he heard the speech. He didn't quite understand what service department meant.

After scratching his head, he explained, "the fierce knife pierced the wallet and directly stabbed it into his chest. This situation is exactly the same as the previous two cases. This is the third case."

Just as everyone was about to ask for details, a middle-aged woman in the crowd suddenly gave a short scream, turned in panic and fled to the car parked on the roadside.

"Hey, that aunt..."

When he was just about to catch up, he found that the car had disappeared. He stopped helplessly and sighed, "Damn, she ran away!"

"Don't worry, I've written down the license plate number. I'll let people check back and know the identity of the aunt."

Conan went to Ping Ci of the service department and asked seriously, "service department, please tell us the case you said."

"OK, but this is not the place to talk. I'll tell you at the police station."

Hattori nodded. After the police came to control the scene, they returned to the Osaka Police dongjiri office with Bai yanzhenyu and others to tell the previous case.

"More than ten days ago, the first incident occurred in Fengzhong city. The victim was a middle-aged man named Nagao Yingmin;"

"Last week, a second incident occurred in mufang city. The victim was a middle-aged woman named Xikou Duodai;"

"There were no witnesses in both cases, and the distance from the scene was more than ten kilometers, but another thing in common was the murderous knife."

"I don't know if there is any special reason. After being strangled by the murderer, the two victims deliberately stabbed the wallet in the coat pocket with a fierce knife, and then stabbed it into the heart."

After he told the public the news that Osaka Police had not reported, he asked them to keep the news temporarily, so as not to affect the police's case solving by public opinion.

Everyone knew this, agreed without hesitation, and then began to study these killings.

Baiyan Zhenyu watched the live photos taken by the clothing department, pointed to the wallet on the victim's chest and guessed: "the murderer deliberately pierced the wallet. Could it be caused by money problems?"

"Changwei Yingmin is the manager of the convenience store, Xikou Duodai is the landlady of the wine house, and yean and Ren, who fell down before, are a taxi driver."

With his chin in his right hand, Sakurai explained: "Nagao Yingmin and Xikou have good assets for many generations. There is little possibility of getting involved with the murderer because of money, and there is nothing in common except the way of being killed."

After listening to the explanation of nobuji, Bai yanzhenyu shook his head and reminded: "no, this deliberate practice can basically rule out the possibility of unintentional killing, so there must be something in common, but you haven't found it yet."

With a slight frown, Nobu explained: "although the schools where they were born, grew up, studied and worked are all here in Osaka, the region is completely different."

Officer Sakata ran into the house from the outside and heard the conversation between the two. He said excitedly, "brother Pingci, this little brother Baiyan is right. We have found the common ground of the victims!"

"Really?" Hisashi was surprised and couldn't wait to ask, "what do you have in common?"

"It's all in here."

Officer Sakata waved a video tape in his hand, turned on the projector in the room and played out the contents.
