"Shhh Tap! ”

In the bowling alley, Yuan Zi took a cold towel to cover Gao Cheng's face, and after seeing Kyogoku's true strength, Shiliang Zhenchun's second attack with anger was really hard, and Gao Cheng's face was swollen enough after a while.

"Really, why can't you hide from it every time?" Yuanzi helplessly glanced at Gao Cheng, who was crying out in pain, and said distressedly, "I knew that they were powerful and ran over to persuade them, wouldn't it be nice to explain clearly." ”

"I didn't think too much about it, I could have avoided ......"

"What are you hiding? The other party is all perverted, didn't you see Shiliang and Xiaolan fight last time? ”

The garden said angrily according to Gao Cheng.

"That Kyogoku is really even more terrifying, how can you mess around like this?!"

"Not in the future," Gao Cheng honestly admitted his mistake and changed the subject, "Did something happen outside just now?" It seems that there is a police car......"

"Don't even think about going, give me a good rest! Anyway, there's Uncle Kogoro out there, too! Yuanzi thought of Xiao Ai's private advice, and hardened his heart to stop Gao Cheng.

"That's right......

Gao Cheng looked out itchingly.

In the parking lot of the bowling alley, a murder suddenly occurred in the heavy rain, and the squinted Maori Kogoro was involved in the murder because he taught two female teachers to play bowling.

The scene of the murder was an independent temporary toilet standing in the corner of the parking lot, a female teacher searched for her missing companion, and when she finally opened the toilet door, she found her companion who had been mysteriously drowned, a male teacher who taught physical education.

Conan stood outside the toilet and asked the forensic officer who was checking the toilet inside, "Just help me remove the spare toilet paper from the cabinet above." ”

"I can't really do anything about you little ghost...... Forget it, it's the Maori detective asking you again, right? ”

The forensic staff stood up and took away the roll of toilet paper placed on the upper partition of the toilet, and suddenly found that there were burnt marks on the ceiling, and they were stunned, and hurriedly took pictures for evidence.

"I see." Conan found the last clue and laughed at the corners of his mouth in the drizzle.

I'm sorry, Joto, you can take care of your injuries, and leave this case to me......

Seliang Shinjun hid in the corner, looked at Conan, who was communicating with the forensics, and quickly tapped his finger on his phone to send an email.

"It looks like he's found out the truth, but isn't it the same as my reasoning...... I've been a little less confident lately. ”

"Click!"

Immediately afterwards, Sera Masumi secretly took a photo of Conan and sent it.

"It's this kid, surprised, isn't it?"

"Toot toot." The email was almost replied to in seconds, which made the small smugness on Shiliang Zhenchun's face immediately turn into astonishment, and he looked at Conan in confusion.

"If it's him, it's fine...... Strange, how could the second brother know this child? ”

"That's the way it is," in the bowling alley, Yuan Zi made a special trip to understand the case, and said to Gao Cheng, "The science teacher helped the drunk physical education teacher to sleep in the car in the parking lot, and then went back to the bowling alley......

"As a result, an hour later, when the math teacher went to the parking lot to look, he found that the physical education teacher was missing, and Uncle Kogoro and they helped them look around, and when they returned to the parking lot again, the science teacher found the body in the toilet......"

"Wait," Gao Cheng interrupted in thought, "who found the body?" ”

"It's that science teacher, I heard that after the corpse was examined, the time of the victim's death was the time when everyone left the parking lot and went out to find someone," Yuan Zi twisted his brows and tried to explain, "So the police said that it should be the victim who woke up and left, got into an argument with someone, and was thrown into the temporary toilet after being killed, the murderer is a very powerful person, because there are traces of trouser pockets on the waist, it may be that the murderer is directly carrying the corpse......

"However, there seems to be some problems, because the prisoner used a stun gun......"

Yuan Zi said that his thoughts were all in a mess, and he helplessly spread his hands and said, "I finally asked Xiaolan about this." ”

"Have you looked for a toilet before?"

"It seems that there is a sign for maintenance outside the toilet......"

"Did the police find anything suspicious? For example, fishing lines and the like. Gao Cheng asked carefully.

"Fishing line?" Yuan Zi was stunned, "No, but when I came back just now, they seemed to have found wet towels and four empty cans with burnt mouths in the trash can next to the toilet, and there was still the smell of kerosene in them." ”

Gao Cheng leaned back in the chair and touched his chin.

The clues are still very vague, but from the clues provided by the garden, it seems that the first crime scene should be in that temporary toilet, there must be a reason behind the phenomenon, and the murderer has no reason to take the risk of transferring the body for no reason.

The toilet was marked for maintenance in advance, so there is a high probability that the physical education teacher who disappeared at the time was trapped inside, plus a stun gun and a suspicious empty can found in the trash can.

What is certain is that this was a planned crime.

In Gao Cheng's view, the really difficult case is not what bizarre criminal methods were used, but whether there are no traces, and this case is destined to leave too many traces from the current point of view.

And the design is so complex and bizarre, but it shows a message.

The murderer needs to interfere with the police investigation and create difficulties for the police, that is, it is easy to find himself if he does not do so, and as in most incidents in Conan, the prisoner with this idea is either at the scene or is a suspect who can easily be targeted by the police.

Of course.

If it is easy to be investigated, of course, you need to prepare an alibi for yourself, and on the other hand, the two female teachers who came to the bowling alley with the victim are very suspicious.

"If that's the case," Gao Cheng reasoned, "the prisoner must be the science teacher." ”

"Huh?" Yuan Zi wanted to continue running, and was surprised when he heard this, "Why? That science teacher has an alibi......"

"So, sometimes an alibi is important, but sometimes it's not credible at all," Gao Cheng touched his still swollen face and explained with a smile, "First of all, the science teacher took the victim to sleep in the car, and then the female teacher found the body, and if I guessed correctly, the victim never returned to the car......

"I'm afraid that the science teacher will let him hide from the rain in the makeshift toilet on the way, saying that he forgot his car keys and wants to go back here to get them, and when he enters the toilet, he will immediately use a stun gun to stun him and trap him in the makeshift toilet......

"Although I don't know what murder methods were used later, when I went back to the parking lot later, I should have taken advantage of the time when I went to the toilet to find someone, and if I drowned, it was probably related to the rain and those suspicious empty kerosene cans, and then, as long as the victim was not killed immediately, he could act with others as an alibi."

"So what method was used to make the victim drown alive in the toilet?" Yuan Zi questioned his waist.

Hmph, obviously I didn't investigate carefully, I didn't even see the scene, and I said it so decently, I was just teasing her......

"I'm also curious," Gao Cheng's eyes flickered, and he couldn't wait to see the scene with his own eyes, "No matter what technique is used, you must deal with the traces afterwards, those few suspicious empty cans are evidence, and they are thrown in the trash can next to them, indicating that there is not much time at all, so the prisoner should be the science teacher who found the body in my opinion, Yes,

The question is what exactly was used, and why was it not used when the victim was locked in the toilet in the first place, so that when he returned to the parking lot, he could pretend to find the body, so that the alibi was also valid and the risk was less...... From this point of view, the method of killing itself should be related to time......"

Gao Cheng paused and continued: "The words of the science teacher, although I am not sure, I think it should be the use of heavy rain to soak the bottom of the toilet, seal the toilet vent and door crack, and burn the air with kerosene inside, and the heated air expands and escapes from the water below.

But when the fire is extinguished, the cooled air shrinks rapidly, and the water underneath is immediately sucked into the sealed toilet and the victim is drowned, which is theoretically possible. ”

Saying that, Gao Cheng said to the garden again: "Let's go to the scene again, there must be a lot of traces left in the conditions for realizing these!" ”

Yuan Zi listened dumbly, nodded again and again and ran out of the bowling alley.

"Good!"

My own man is different, the reasoning seems to really make sense, and it makes sense, and the rest is on-site verification.

You must check it well, and even if the reasoning is wrong, at least find him a step down......

"That's right," at the scene of the murder, Shira Masumi looked at Mori Kogoro who was anesthetized by Conan, stared sharply at the female science teacher, and reasoned, "When you go back to the parking lot, remove the towel from the drain, drain the stagnant water, tear off all the tape, and throw the extinguished cans on the shelves into the trash......

In order to cover up the water in the toilet, I also specially changed a new roll of toilet paper, and finally let out a miserable scream as if I had just found the body......"

Shiliang Zhenchun smiled: "The key to this technique is how to make the body be found as soon as possible, because if it is found too late and the estimated time frame of death becomes larger, your alibi will not be established, so the prisoner can only be you, as the first discoverer of the corpse, and you are the only one who can buy time for the rain to accumulate."

"Since the tape is not in the trash can, you should have washed it off, and there should be fingerprints left on it, as long as you look for it in the sewage tank under the toilet, you can find it."

As he spoke, Sera Zhenchun bared his little tiger teeth and looked at the sleeping Maori Kogoro and Conan who was holding a bow voice changer in the back.

"Am I right, Mr. Kogoro, who is sleeping?"

"All, all right......"

The garden, which had just arrived, stood beside it in a daze.

Although Gao Cheng's reasoning method is very different, directly locking the prisoner at the beginning, the result is almost exactly the same, as if he saw the scene with his own eyes.

Because the corner of the toilet is relatively low, this will be because everyone blocked the drain again, and the water even overflowed to the side of the car next to it, and the sleeping Kogoro also sat in the water, and his whole ass was blistered.
