Kazukawa and Hui stood on the side with their hands down, watching Gao Cheng devote themselves to the case and seriously discuss it with Officer Henggou, looking at Gao Cheng to definitely deduce.

"If the murder weapon is a thin line, it is either hidden, or it is rushed into the sewer or burned directly, it is unlikely to be found, maybe it will be much more convenient to investigate from the source of the murder weapon......

Gao Cheng temporarily put down the murder weapon, continued to observe the scene, and noticed that there were faint blood stains on the head of the bathroom shower.

Connecting the previous clues together, the murderer entered the duck's room 10 minutes before the crime, and went to the bathroom to take a bath, and then he should have tricked the duck into the bathroom, attacked the back of the duck's head with a shower, and then took the opportunity to wrap the duck's neck with a thin thread, but was secretly photographed before the duck's time......

"Isn't this a movie played by Kazumi?" Henggou picked up a box of videotapes in front of the TV, "How can there be this?" ”

"That roll is a rented video from Mr. Kamoshita," the officer explained, "and the hotel seems to have a rental service for tenants......"

"In other words, Mr. Duckshita has seen this tonight, right?"

Henggou looked tense and inserted the tape into the playback port.

"I don't know if there will be any clues......"

Gao Cheng followed and watched the video.

The movie is a horror film called "Steps of a Small School", Henggou looked at the strange picture on the screen and instantly changed his face, and cold sweat broke out on his forehead.

"This ...... This movie looks weird and scary......"

"Officer, you shouldn't be scared, right?"

"How, how could it be ......?"

An hour and a half later, Henggou watched the end of the movie with trembling teeth, turned to Gao Chengqiang and smiled: "Ha...... Haha, that's interesting...... But I don't think there's any clue......"

Gao Cheng ignored the stiff smile of Henggou, thought about picking up the videotape box, looked at the 94 minutes marked on it, and then looked at the movie that ended in 93 minutes.

"One minute less content ......"

"Huh?"

"Generally, movies have a beginning, at least the film company and the main creator or something like that, right?" Gao Cheng tried to replay the video and said, "Mr. Duckshita's videotape is 1 minute less than normal......"

Henggou said in a daze: "What's going on?" ”

Gao Cheng put the videotape box on the table, raised his eyelids and said with a solid gaze: "If the other videotapes are normal, then there is only one possibility, the murderer may have cut off a one-minute tape as a murder weapon, just check whether there are any traces of bonding in the videotape." ”

"But the black line on the photo is as thin as a kite...... Is it twisted together? ”

"It's not that troublesome, in fact, you just need to stretch the tape hard, the tape tape is very malleable, and there should be no problem with 1 minute length of 80 cm to more than 2 meters, it is more than enough to wrap around the duck's neck as a murder weapon, and it is also very easy to deal with because of flammability......"

Gao Cheng got up and walked to the bathroom door.

"And the reason why the murderer put the duck's corpse in the bathtub should also be convenient to wash off the magnetic powder left by the tape on the duck's neck to avoid revealing traces, and the biggest problem now is ......"

Gao Cheng's gaze swept over the wound on the back of the duck's head, turned to the lotus shower hanging on the wall, and the clues in his mind seemed to be strung together by something and quickly flashed a bright line.

"The reason why the murderer did not wear clothes...... It should be to avoid the blood under the duck from splashing on the clothes, so I will use the excuse to take a bath and enter the bathroom......"

"Police Department!" A police officer came back with the test sheet and said, "The results of the examination are out, the blood stains on the bath spray head are consistent with the blood type under the duck, and the murderer did use the bath spray head to stun the victim and then strangle him to death!" ”

Henggou perked up: "Detective Chenghu, you are right!" But even so, there is still no way to determine the prisoner......"

"Who is the prisoner...... I already know. ”

"Oh, got it...... What the?! ”

Henggou's figure was stunned, his thick eyebrows widened, and his eyes looked straight at Gao Cheng.

"Already, already known?"

"As long as you avoid preconceived ideas and start from the beginning, it's easy to figure it out......"

Gao Cheng turned to the three waitresses who had been brought over with him, and raised his finger in the puzzled gaze of the three people.

"Yes, if the dot on the photo wasn't a mole, everything would make sense...... Miss Bessho Noboru Shiko, the murderer is you! ”

"Me?" The short-haired hostess's face turned pale, "Detective Cheng, Chenghu, what are you talking about, there is no mole on my chest......"

"It's true that there are no moles, but ......"

Gao Cheng took the duck off the phone.

"The point on the murderer's chest is also not a mole, but the blood stains splashed on the body when you hit the duck's lower head with a bath spray, which looks easy to mistake for a mole, but only when you see the photo, it is clear that it is a blood stain that has not been dealt with in time......"

"Wait a minute!" Sanzhi Asaka stepped forward and said, "Why do you say that about Dengzhizi?" Didn't she take the initiative to show you your chest? ”

"That's the reason," Gao Cheng calmly looked at the silent Bessho Noboru Shiko, "The blood stains on his chest were washed away as early as when he entered the open-air bath, but the blood stains on his clothes were not treated, and it would be easy to be found if he really checked it, so he would take the initiative to grab the collar and open his chest, so that the police could avoid the body search if there was no black mole......"

"How, how could it be ......?"

Sanzhi Asaka was speechless, and looked at the short-haired hostess suspiciously: "Dengzhizi ......"

Yokozo came back to his senses and uncovered the neckline on the left side of the short-haired hostess with a serious face: "There is indeed a little blood stain on the inside of the kimono!" Sure enough, it was you, Hehui's mother, Wenzi, who intimidated Hehuijun's office, and now killed the people under the duck...... Now do you have anything else to say? ”

"I was just joking at first......"

The short-haired hostess bit her lip and lowered her head.

Because the child who was abandoned by himself was famous, he reluctantly sent postcards...... I want to separate Kazuki from such a mother, maybe because I can't have children......"

"So ...... said"

"Yes, I'm not Hehui's mother, and Hehui's father is not a murderer, I just want the office to stop handing over Hehui's mother's postcard to Hehui......"

Short-haired hostesses, don't overdo it.

"But after a while, there was really money deposited into my account, and when I didn't know what to do, the duck came to me...... I called the room to explain to him, but the guy laughed and said that even if it was fake, it would be just right to squeeze me dry......

"I'm really scared."

The short-haired waitress looked at Mizhi Asaka.

"However, the mood of a woman who longs for a child...... I guess I have a little bit of an experience......"

"Let's talk about the rest at the police station," Officer Henggou nodded ignorantly and turned to Gao Chengdao, "Then, Detective Chenghu, can you go to the police station by the way to help make a record?" ”

"No, it's not me who called the police anyway, and you all know the case," Gao Cheng looked at the little kid who was asleep on his stomach, "And there is this kid who needs me to take care of ......"

"Uh......"

Henggou remembered the rumors in the police world, this young detective really rarely makes notes or anything like that, it's really ......

"Alright then, I'll get in touch with you about something."

"It's already half past three......

Gao Cheng yawned, picked up the sleeping little kid and followed him out of the murder scene.

What kind of sin have you created, why are you not taking care of the little ghost or taking care of the child on the way lately?

The dignified detectives are about to become nannies......

Sanzhi Asaka stopped at the side of the aisle, silently watching Gao Cheng walk by, and a hint of softness flashed in his eyes when he looked at Jukawa and Hui.

"You're Hehui's mother, Wenzi, right?" Gao Cheng suddenly turned around.

"Huh?"

"This kid still remembers falling asleep while watching the sound of chopping vegetables while looking at the black mole when he was being held by you, but he was a little mistake...... Gao Cheng said calmly, "He Hui probably grew up in the church, but ordinary housewives don't hold their children to cook, in fact, he was carried on his back at that time, that is, his real mother is you with a mole on the back of her neck......"

Sanzhi Chaoxiang's eyes dimmed: "I ......"

"I'll explain it to his firm," Gao Cheng said with a smile, "After being blackmailed, the firm didn't give the postcard to Hehui, but it shouldn't be in the future, keep writing, although this little ghost says he doesn't like it, but making the postcard dirty and wrinkled is evidence of reading it repeatedly while crying, and I definitely want to receive the postcard you sent again......"

"Yamato ......"

Sanzhi Chaoxiang choked up and watched Gao Cheng take Juchuan and Hui back to room 308, don't turn your head and wipe the corners of your eyes.

"Thank you, Detective Joto."
