"So, what are you doing here?" Mizuma looked at Judy-sensei.

"We saw a lot of police cars through the windows facing the street, so we came to take a look at them if we were curious, and we were very sorry. Xiaolan replied.

“dei！dei！dei！seeing-is-believing!” Teacher Judy said excitedly.

"Don't make a mess!" Shui Jianyue shook her head helplessly, the scene of the crime is not just to come and leave as you want, since the three of them have already broken in, they can only wait for the case to end before letting them leave.

"Police!" Shiratori walked over, "The surveillance in the parking lot happened to film the four cars in. “

"That's good news, good luck. Mizumayue was pleasantly surprised and said that it was much more convenient with monitoring.

"But it's not all due to luck, we also chose a place where the surveillance footage will be clear before parking here. Twilight Yoshito interjected: "After all, they are very expensive cars, if there is any damage or theft, it would be better to check the surveillance video." “

"I see, let's go and contact the mall to get the footage. Mizuma Yue nodded and ordered.

"The police department, the autopsy has been completed, and some suspicious traces have been found. Police officer Yasuya Yamamoto came over and said.

Reaching out and taking the autopsy report, Mizuma looked at it.

The murder weapon was an extremely thin wire that strangled the deceased's neck with great force until the trachea rupture.

There was no Yoshikawa thread on his neck, and there were no sleeping pills in his stomach, but there was a large amount of alcohol in his stomach and even in his blood, which was the same as the drunken and comatose state of the deceased described by the three people.

But this also means that when strangling, not only is the power very strong, but also the speed is very fast, otherwise the deceased will wake up with a strangulation sensation in the neck before he dies, and no matter how drunk he is, it will be the same.

In other words, whether it is an automatic cord reel or a car, even if it is combined with a pulley group, it cannot be used to kill people.

The target of the murder weapon should be locked onto something more powerful, Mizuma Moon thought as she asked, "So, what is the suspicious thing?"

"It's blood. Yasuya Yamamoto said: "At the time of the autopsy, a very fine bloodstain was found on the back of the deceased's seat, which may indicate that the murder weapon was wrapped around the deceased's neck and wrapped around the chair, and the forensic department was notified for examination after the autopsy was completed." “

"I see. Mizuma Yue nodded, which showed that the murderer did not stand directly next to the deceased and strangled him, but arranged a mechanism to pull the line farther away with the help of machinery.

"Prepare for the luminol test. Mizumatsuki's heart moved, and he commanded.

"Got a clue?" Miwako Sato had been standing by and watching, and when she saw Mizumatsuki's expression, she knew that he had an idea.

"Well, try your luck. Mizuma nodded.

It's better to guess what kind of machinery the murderer used first, in this underground parking lot, the most intuitive thing to find...... It seems that there are only cars left. Mizuma Moon found out.

"No......" Mizuma Moon shook her head to herself, first of all, after the three of them came out of Yoshito's car, because they were holding a thin line in their hands, although the dimly lit thin line in the parking lot was not easy to be seen by their companions, but they shouldn't have the courage to run too far, so if they want to hold the car, they can only hold the nearby car.

But they don't know when the nearby car will drive away, and if they don't drive away until the deceased wakes up, it wouldn't have been a failure to let the deceased wake up and find the noose around his neck.

If you see some people coming out of the mall and ready to get in the car and leave, you can tell that they will start the car immediately, but it is obvious that someone else is already in the car and rushes to someone else's car to tie the line, whether it is the car owner who is about to leave or the murderer's companion will not ignore it.

"The police department, the camera footage is back. Police Officer Gonbei Uchida walked over with a laptop in his arms.

Mizuma and Miwako Sato, as well as three other suspects, all surrounded them.

Uchida Gonbei operated, and quickly transferred the picture out, and then transferred to a place a little before the four people came back, there was a vacant space between the car of Ruiji Bukuro and the car of Yuya Companion, and on the other side of Yuya Awa's car was Megumi Taiyama.

Soon, Yoshito's car appeared in the picture, and smoothly drove into the car of Ruiji Fubukuro and Yuya Companion, and then the three of them got out of the car in the order they said before, and it can be seen that they also tried to communicate with the deceased at this time.

"Hmm? How did you end up in your own car. Seeing the picture of Butaka Ruiji and Taishan Megumi walking back to their cars, Mizuma asked.

"I just took my coin purse, and I didn't touch the backpack behind me at all. Budai Ruiji said, and Taishan Hui also gave the same answer.

Indeed, although the camera footage is not very clear, it can be seen that the two men are just doing something on the bridge - according to the two people, they opened the glove box to find something, and did not touch the backpack with the automatic reel in the back seat or the toy car on the passenger seat.

The next two men got out of the car and walked to the mall with Yoshito Twigki, not seeing anyone approaching any other vehicles during this time.

After the three of them disappeared from the frame, Mizuma pressed down the fast forward, allowing the screen to quickly transition to the time when the corpse was found.

During this time, cars around the area came in and out, and the four Porsches remained motionless in the center of the frame, and there was no sign of anyone approaching the Porsche.

The deceased was sitting in the car, and it was estimated that he had already died in terms of time, but there was no difference between his current state and the state of the three when they got out of the car.

Until Yoshito Twilight reappears in the picture, opening the car door as if calling for the dead, and then screaming and retreating, Conan and Mizuma Tsuki running one after the other, there is nothing to see in the picture.

How did you see something?Miwako Sato asked Mizuma Tsukimi, because she didn't see anything.

Mizumatsuki didn't speak, but turned the picture back to when the three people just got out of the car, and continued to play it from here until the three people left the screen position, and replayed it four or five times over and over again before stopping.

It wasn't because he gave up or found something, but because the equipment for the luminol test was ready.

"Guys, we're going to spray a blood test called luminol on your car, rest assured that it won't cause any harm to your car and will be easy to clean. Mizuma turned back to the three of them and said.

"No problem. Yoshito Twilight was the first to agree.

"It doesn't matter as long as it's washed off. Cloth Bag Ruiji also agreed.

"Clearing suspicions is more important than anything else. Naturally, Taishan Hui will not refuse.

"Let's get started. Mizumayue gestured to the forensic department, which was already eager to try, to signal that they were ready to start, "The specific content of the test can be explained by the county police officer." “

Then everyone came to the car of the Twilight Wood Yoshito, and the Shan County Gongwang walked to the front of everyone and pointed to the seat made by the deceased, a thin blood mark, and it was also in the position of the back of the chair: "The height of this blood mark is below the neck of the deceased, and we speculate that after the murderer went around the neck of the deceased, there was a circle around the back of the chair, and then in the process of strangling the deceased, the thin line was embedded in the skin of the deceased, and then the thin line broke, and the thin line stained with the blood of the deceased was continued to be pulled and then bypassed the back of the chair and crossed this line on the back of the chair." ”

"So, now it's looking for bloodstains, right? If you find bloodstains, you'll know where the murder weapon went, right?" Budai Ruiji and his mind turned very quickly, and he understood the meaning of Gongwang in Shanxian County.

"That's right, and this is the luminol reagent, which can react with blood, no matter how rare and dull the blood stains are, they will not be ignored. Shan County Gongwang nodded, picked up the spray can in his hand and sprayed.

"The reaction produced is fluorescent, which is difficult to observe under normal circumstances, and this is where ultraviolet light is needed. While explaining, Shan County Gongwang picked up the ultraviolet lamp and irradiated it.

"Even if you say it, we don't see anything special happening. Twilight watched blankly as Shan County Gongwang sprayed in his car, but nothing happened.

"Look at the door!" shouted Miwako Sato.

Gongwang of Shan County hurriedly shone the ultraviolet lamp at the door of the car, and found a small fluorescent spot on the edge of the door, and if you didn't look closely, you thought it was the reflection of the light.

This shows that ...... "Twilight Yoshito didn't understand."

"It means that the murder weapon passed through here during the process of being removed, so some of the blood stains on it were left on the car door. Mizuma explained, "Since the marks were found on the door on the left, let's first identify Mr. Companion's car on the left, but unfortunately he himself can't express whether he agrees or not." "To the left of Yoshito's car is the car of the deceased's companion Yukiya.

The four officers of the forensic department rushed up, and poured the spray cans in their hands on the expensive car, and after estimating that they had sprayed the whole car to the side, they brought a huge black cloth, and each of the four grabbed a corner to block the lights of the parking lot. Kept Yukiya's car in the dark.

Immediately after that, two forensic personnel stepped forward and repeatedly swept with ultraviolet lamps.

This time it was easy to find, there were straight but intermittent fluorescent lines on the ground, and two small fluorescent dots were also found on the car's ground, and the thin lines were in the same spatial section.

And the murder weapon moved straight away, and what about the destination? After passing the car that accompanied Yukiya, it was ......

"Hey, what do you think I'm doing?" Finding that most of the people's eyes were on him, Taishan Hui asked angrily.

"Next is Miss Taishan's car, don't you have more reasons than me?" asked Mizumatsuki.

"Hmph!" Taishan Hui snorted coldly and did not answer.

Starting from the outside of the inspection car, in the same order as the inspection of Yukiya's car, it didn't take long for the ultraviolet rays to hit Megumi Taiji's car.

It's so obvious...... What did everyone think in their hearts, on the door of Taishan Hui's car, there were several staggered lines like elementary school students' papyrus, as if there was worn glass on the ground.

"What is this?" Tai Shan Hui stopped: "What the hell is this thing you are photographing? Say it's bloodstains, bloodstains, do you turn off the lights, take a good look at the bloodstains here, don't tell me about the red body!"

"If a drop of blood is integrated into a basin of water, can you still see the color of the blood?" Mizuma asked: "No, it can't, and the luminol reagent is an ultra-sensitive reagent that can detect even such diluted blood stains, so if you can't see it, it doesn't mean that there is no trace of blood left!"

"Then keep looking! Find out where the murder weapon is? Haven't you already checked it? I don't have any props here that can be used to strangle people, and it's obvious on the surveillance that I haven't done a big move to strangle people, right?" Taishan Hui continued to ask.

"This kind of problem, it's easy to get the result with a simple calculation" Mizuma Yue smiled disapprehantly: "The deceased's neck was broken, and the rope fell into about one, plus the length reserved for the deceased not to be detected by the deceased before, in fact, it only takes enough strength to shorten the rope by five or six centimeters, you must know that the shortened circumference is not much related to the original diameter." “

"As for your props, I want to ......" Mizuma Yue dragged a long note, walked to Taishan Hui's car and opened the door, after starting the car, rolled down the electronic lift window, sprayed some luminol on it, and then took the ultraviolet lamp, and sure enough, there was a bright fluorescent spot, which means that the blood concentration is much higher than other places.

Of the four Porsches present, yours is the only one with electronic windows, and in the entire parking lot, only the window lift is the most powerful machine. Shui Jianyue gently touched the fluorescent dot behind him, and as expected, there was a little burr daring, it turned out to be a small pit on the glass that was barely visible to the naked eye to recover the murder weapon.

"What nonsense are you talking about?" Taishan Hui couldn't refute it, so he could only shout blindly.

"It's not nonsense. Mizumatsuki said with a smile: "Using Mr. Companion's car, the fluorescent point on the site as a fulcrum, calculating the height difference between the opening of the window and the closing of the window, the shortened length can be calculated to be far more than six centimeters, which means that it is completely feasible to use the window to tighten the rope and strangle the deceased, and if it weren't for this, you would explain to me why there is a small pit in your car window?" It's this bloodstained position, don't tell me I knocked it out myself, the glass is not so strong, except for the case of deliberately drilling out round holes, the marks of the knock will gradually increase soon!" Looking at Taishan Hui, who had fallen into helplessness, the corners of Mizumatsuki's mouth and eyes began to appear in a mocking tone.
