Conan: Open the Door, I’m a Policeman

"No," Mizumayue said shamelessly. He was the one who was most suspicious of the people present now. Wouldn't he let him clear the evidence by letting him go. "Now you are one of the suspects. If you want to leave, you must go through a search of your belongings and be accompanied by a police officer. I hope you can understand."

"Uh... don't bother, it's not a big deal." The president sat down embarrassedly, and in Mizumayue's eyes, it was clear that he had a guilty conscience.

After talking for a while, Fujiwara Sakagi came in again with a stack of reports in his hand and handed it over to Mizumayuki.

Mizuki turned around, and when the forensics department investigated the monitor on the roof of the office building, they found that the monitor could swing its head, but the power of the rotating shaft was a bit too large, and a comparison was also found on the edge of the roof. Deep cuts, extended cuts were found to be roughly connected to the monitor and the I-beam drag marks on the abandoned building opposite. Along with the report came photos of roof traces and monitors, as well as some distance and weight data.

Interestingly, a harmonica was found at the death scene, which was identified as something of the deceased and initially thought to have fallen from the deceased. However, it was later found that there were no fingerprints on the harmonica, and there were no signs of the harmonica falling on the surrounding ground. It was speculated that the murderer had deliberately placed it under the I-beam for the victim to pick it up.

Mizuki turned the report over, took a pen and wrote and drew on the back of the blank, and drew a sketch of the roof of the second floor, connecting a line between the monitor and the I-beam, assuming a monitor pendulum Head to pull the I-beam, you can roughly calculate the tension on the cable and the power required by the monitor.

However, after calculating, Mizuma gave up, and threw half of the straw paper in Fujiwara Sakagi to let him continue the calculation. Miwako and Sato went out to have a small meeting with colleagues waiting in the corridor.

"The police department supplement, what should I do now that I'm stuck in a bottleneck?" Fat Ball Qianhu Yishen asked. It has to be said that after the promotion of the Mumu police department, the status of Mizuma Yue has improved a lot. The police officers under her do not ask the police department Sato Miwako, but ask the police department to supplement the water Mazuki for advice.

Mizuki thought for a while and said, "Come on, let's have a live teaching class."

"Take this opportunity today to talk about the pre-guessing method. The pre-guessing method is used in the current situation where there is no clear pointing evidence, but there are relatively few suspects."

"The first step is to guess a murderer. I personally think that the president of this case is the most suspicious. Let's assume he is the murderer. Do you have any opinions?"

"No..." the surrounding police officers replied.

"Assuming he is the murderer, what techniques can he use? Sakagi, have the data been calculated?"

"Report to the police department, the data is calculated, that monitor can pull the I-beam!"

"Okay, then I guess he used the monitor to swing, pull the I-beam down, and smash the deceased to death."

"The next step is the second step, speculating on the action. We found a harmonica without fingerprints at the scene, so I speculated that he stole the harmonica of the deceased first, in order to avoid leaving fingerprints, he wiped it and put it on the ground to attract the deceased. Attention, use the monitor to pull the I-beam down while the deceased picks up the harmonica."

"The third step is to corroborate. If you want to achieve this method, it will leave traces, such as the cut marks on the edge of the roof. At the same time you look at this photo, there is a protrusion on the bottom of the monitor that is obviously welded and has no function. From the beginning, there are traces of being bound by thin wires and being pulled vigorously, which basically confirms the establishment of this technique, and the speculation is reasonable."

"The fourth step is to look for possible evidence. Continue to organize his next actions. After killing the dead, according to the secretary, he sent the secretary to check the situation, and then came down by himself. Then during this period, he did What? Presumably this method requires a thin wire connecting the monitor to the I-beam, maybe a piano wire or a fishing wire, but we didn't see that wire, it's likely he was put away, and it shouldn't be. Time to deal with that thread, he was trying to leave just to deal with it. It could be on him or in his office now."

"The last step, confirm, you go to contact this office to apply for a search warrant, and I'll talk to the president. Okay, get out of class." Everyone dispersed and performed their duties.

When Mizumayue walked into the office, the president immediately greeted him and asked, "How about the police officer, is there a result?" Mizumayue felt that his mental state was not very good, and he seemed to be very nervous.

"Sit down first, and I'll tell you what the police found," Mizumayuki nodded and said.

"Now we've found out... blah blah blah... so presumably you first... blah blah blah... and let him come over here to talk to you, count the time he walks down the alley, use the harmonica to prolong the time he's standing there, Use the monitor swing to pull down the I-beam and crush the dead."

"Uh, according to what you said, the police officer, as long as you find out the rules, anyone can use the automatic swing of the monitor to commit crimes!" The president defended.

"The suspects are roughly you and the secretary. According to what you said, the secretary didn't have time to deal with the line, so we locked you. And if the automatic head-swing is used, how can the prisoner ensure that before the deceased arrives, the automatic Swing your head and fall off the I-beam? So only you who are sitting in the office, UU Reading www.uukanshu.com can manually make the monitor swing at the right time, and only you, the president, can install a rotating Monitors with much more power than needed.”

"No, that's not right." It wasn't the president who was the naysayer, but Kogoro Mouri. "It's not about time, but for visibility."

Mizumayue raised her eyebrows. The president's office only had a window facing the street. It is estimated that the secretary said that the president had never come out when the incident happened. How could he see it?

"At the time of the incident, a cleaning car of the company was parked across the street, but later the president asked to drive away, so you didn't see the police officer," Kogoro Mouri said eloquently, "that cleaning car has a characteristic , There is a small piece of glass that can be used as a mirror at the fisheye position. My daughter Xiaolan was still using that piece of glass to look in the mirror at the time of the incident. I think at that time, President, you should be using a telescope to observe the alley through the glass reflection, right? Because Xiaolan interfered with your vision by looking in the mirror at that time, so you pulled down the I-beam ahead of time, causing the deceased to be smashed to death before picking up the harmonica. Am I right? Mr. President."

Mizumayue pouted. There was a car parked opposite and then drove away. He asked them eight times before about the situation at the time of the crime, but no one said anything... The problem of these detectives not cooperating with the police I didn't change it again, no matter what clues I had, I swallowed it in my stomach and refused to say...

The power increase of the PS monitor is a setting that I added myself, because every time I see this, I want to complain: My home appliance fan can also swing its head, but the power is poor, even if the monitor is advanced or powerful, it will not work. As for pulling a piece of I-beam, right?
