"Detective Joto," the officer asked, "are these yours?" ”

"Well, let's check it inside again to see if there's a possibility of hiding the murder weapon."

Gao Cheng had no intention of stopping the police investigation, although it would be a lot of trouble to really find the murder weapon.

To be honest, despite his reputation as a detective, the Gunma Prefectural Police can still ignore him, not all police officers are rare detectives, and his role as a special adviser is only useful in Tokyo.

Since he can have the current respectful treatment, he must also have self-knowledge.

"Whoa!"

The heavy rain was still falling, and in addition to the footprints, many traces were washed clean, such as blood stains, which caused a little trouble to the police.

After several police officers searched the camping luggage to no avail, they took saw knives and machetes to do the luminol reaction to test for bloodstains, and Gao Cheng's focus was on the hammer that seemed to have nothing to do with the case.

It was a new hammer that I had bought to pitch my tent, but it already had inconspicuous scratches on it.

It's just that I really can't see what it has to do with the case......

In the living room of the house, not only the tools used by Gao Cheng for camping, but also the police also asked everyone to take out all the knives, including the kitchen knives, shovels, sickles, axes and scissors that Tanaka's family already had.

As for the temperament men, they didn't bring anything, and they didn't find anything after the search.

"Well," Yamamura said as he watched his men test for bloodstains, and muttered to the old woman, "Is that really all there is?" ”

"There's also my grandson's toolbox in the warehouse, but it's probably rusty......"

"But I heard there's a pointed kitchen knife with a red handle, don't I?"

"It's just that the child is sleepy and misunderstood," the old woman denied with her hands behind her back, "I don't know what kind of kitchen knife with a red handle, probably because the child has been thinking about the mountain demon mother-in-law or something, and was so frightened that he read it wrong." ”

"Really?" Yamamura looked at Gao Cheng uncertainly, and said with a grin, "It's always me, I still have to investigate this family thoroughly, please wait here for a while......"

"Let's go to the warehouse first...... Where is the warehouse? ”

"Over in the kitchen."

Conan got rid of Ayumi and followed a few criminal policemen to the warehouse, Gao Cheng looked at the active Conan, but did not follow, but silently looked at the temperament man Andalai who lowered his head and didn't know what he was thinking, and the long-haired man Kagawara Fengya.

Miss Akane's body has been taken away by the police, and the neck wound should be further examined, at least to determine what kind of murder weapon it is, but there will be no results in the short term.

Gao Cheng thought about the situation at the time of the crime again.

Since there were no other footprints, it was true that only one of the Andalai Lamas could commit the crime, and the most suspicious thing was the shoes.

In a hurry, Conan rushed out with his sneakers, but at that time, the shoes of the Andalai were well dressed, obviously they were high shoes, but even the shoelaces were meticulously tied, and when he finally returned to the house, he took some time to untie his shoelaces and take off his shoes.

But the problem arose again, judging from the shoes, the Andalai people did not have time to go back to the house to hide the murder weapon......

Gao Cheng closed his eyes slightly, and the situation at the time of the crime flashed in his mind.

If the murder weapon could have been hidden, the Andalai people may have disposed of it under the pretext of washing their hands......

"Brother Joto," Mitsuhiko kept his distance from the old woman in fear, "I really saw it with my own eyes, and there really is a sharp kitchen knife with a red handle......

"The police have gone looking for it."

"But is that mountain village officer really reliable?"

"Ahh There were several cabinets in the Tanaka family's warehouse, and there were many boxes and boxes, and the high places were full of dust, and Yamamura couldn't help but sneeze when he entered the warehouse.

"Let's find the old woman's grandson's toolbox first." Yamamura confidently ordered.

"Yes."

Conan walked behind the detective and paused as he passed a cabinet to find a number of wooden boxes tied with rope on top of the cabinet, one of which looked much cleaner.

"Uncle Yamamura," Conan began, "there seems to be very little dust on that box, could it be that it was taken down just now?" ”

"Well," Yamamura said with a smile as he looked around at the wooden box, "You don't think there's a murder weapon hidden in it, do you?" I don't think so, no prisoner would put the murder weapon in such a striking paulownia box, and tie it with a rope properly......"

"But it's weird."

"Officer Yamamura," Gao Cheng just walked into the warehouse, "Let's open it first, I believe Mitsuhiko is not lying, and the matter of the red handle pointed kitchen knife should be true." ”

Yamamura was stunned and said: "So the old woman killed someone?" ”

"A knife doesn't necessarily kill someone."

Gao Cheng watched as the criminal police took down the paulownia box, opened it and took out a red knife-tipped kitchen knife wrapped in newspaper.

"There really is!" The detective was surprised and handed the kitchen knife to Yamamura.

"It's very similar to the kitchen knife my mother-in-law used," Yamamura took the kitchen knife and put it under the light to check, "The blade is not notched at all, it seems to have been maintained, and the surface is coated with a layer of oil...... But why did the old woman hide the kitchen knife? I sharpened my knife in the kitchen before 4 o'clock, and it was still very suspicious! ”

Gao Cheng's gaze fell on the name engraved on the back of the knife.

"Xiangtai" ......

This knife should be the kitchen knife of the old woman's grandson Xiangtai.

"Anyway," Yamamura said with a headache, "let's test the luminol reaction first......"

……

"What? None of them have a rumillo reaction? ”

In the living room of the entrance of Tanaka's house, Yamamura was completely distressed, and then his face turned blue again.

"Ladies and gentlemen, none of the knives have been checked for any signs of blood ever attached, and no one has left the house when everyone rushed to Miss Tingqian, who was screaming because of the cut in her carotid artery...... There is only one possibility to say this, is the prisoner really the mountain demon mother-in-law?! ”

"Mr. Officer, please, how can there be any mountain demon mother-in-law?" Kahara Fengya said helplessly, "But in this way, at least it shows that we are innocent, right?" ”

"Well, I still need your confessions as a reference for future investigations," Yamamura said stupidly, "so I'll trouble you to come to the police station another day......

"I don't think we need to change the day."

Gao Cheng stood by the sink of the fish tank with his hands in his hands.

"The prisoner and the murder weapon are still here......"

"Huh?"

Yamamura Cao wondered: "Detective Chenghu, we have investigated carefully, and we have indeed found nothing......

"Of course I can't find it, because the murder weapon that killed Miss Akane wasn't a knife in the first place, but just a sharp weapon that could be used as a knife......

Gao Cheng came back to his senses and faced everyone directly.

"And it's always been right under our noses......"
