After meeting with Officer Gongchang, Gao Cheng got the opportunity to meet with Xuantian.

I don't know if it's true or not, this officer seems to have a lot of respect for his past resume, and I don't know why a fire police uncle attaches so much importance to the cases of other groups.

In the interrogation room, Gentian sat alone with his head bowed, looking frustrated that he had given up on treatment.

A policeman stood outside in distress and reported to the bow commander who brought Gao Cheng over: "He still can't say why, he just insists that it was another self who set the fire." ”

"Hmm."

The factory nodded and motioned for the police to leave, and looked at Gentian, who was already exhausted in the interrogation room, through the glass with a heavy face.

"If you can't find other clues, you can only send him for trial in the end......"

After a pause, Gong Chang sighed and turned to Gao Cheng: "Detective Chenghu, do you know why I believe him?" ”

Gao Cheng was also a little curious: "Is it because of Xuantian's firefighter father?" ”

Bow Commander neither denied nor nodded, but recalled, "When I first investigated Gentian, I once called him to the park and talked to him once, but after 30 minutes, the guy didn't say anything, and just sat on the bench with a sad face, which is similar to now......

"But when I left, I looked from a distance, and saw him leave the bench, desperately looking for something in the surrounding grass, and after a while it rained he gave up, and I understood that he was looking for the cigarette butt I smoked, which was the cause of the fire that killed his father......"

The bow commander silently snuffed out the cigarette in his hand, his eyes earnest.

"I can't imagine a guy like him going to someone else's house and setting it on fire, and I don't want to...... Detective Chengto, I've checked your case, and the solving rate has always been 100% since you became famous, no matter how complicated and difficult the case is, you can find out the truth, can I ask you to help a group of Gentian this time? ”

Gao Cheng looked at the silent Xuantian in the interrogation room, and his understanding of this uncle of the nest deepened.

I am afraid that the death of my father has become a knot in Xuantian's heart, so he will be caught by the real murderer and used by his weakness, so that those suspects, whether they are psychiatrists, feng shui masters, or soothsayers, may mentally manipulate Xuantian.

"Let me talk to him first."

Gao Cheng nodded and walked into the interrogation room, inside Xuantian thought it was another interrogating policeman, but when he looked up, he found that it was Gao Cheng, and he couldn't help but look surprised.

"Detective Joto?"

"I believe you're not the real murderer," Gao Cheng chuckled and stood in front of Gentian, "Do you need me to help you prove your innocence?" There is no commission fee. ”

……

Toshizen Town, Genda family.

When Gao Cheng arrived at the door in the police car of Officer Gong Chang, Uncle Maori also drove over from the other side, and when he saw Gao Cheng, Hattori hurriedly smiled and greeted.

"How? Joto, have we found the prisoner's ignition method first? ”

"I've heard what Officer Gong said," Gao Cheng gave Hattori a dismissive look, "So, how did you make an alibi?" ”

Hattori didn't continue to be proud, his eyes were blazing: "We checked the scene again, the fire point is a white woven light bulb fragments, there are bands of brown burn marks and black circle marks on it, and there are ashes after burning paper towels everywhere in the scorched places, the prisoner should wrap paper towels around the 100w light bulb, and then insert a match, once the surface temperature of the bulb is enough, it will automatically light the match......

"The surface temperature of a 100W bulb can reach 218 degrees, and it is easy to light a match, and the prisoner must have done something to the bulb in the warehouse beforehand, and then sprinkled oil on the floor, and then put the red horse with the base torn off the window to the window, and the time of ignition can be adjusted by the amount of paper towel wrapped around the light bulb......"

Hattori looked at Genda's family and said with a smile: "This is the automatic ignition device of the prisoner, and the most obvious evidence is that there is a glimmer of white weaving lamp in front of the shadow of the red horse printed on the curtain next door!" The next thing is to find out how the prisoner manipulated Gentian and the final evidence......"

"I see," the bow chief pondered, "it seems that it does automatically ignite according to you, but it is also possible that the marks on the light bulb were formed by accident during the fire, and if such a device is used, isn't it possible that all three of them are possible?" ”

Gao Cheng took out the key and opened the door of Xuantian's house: "No matter what, check the ...... first"

"Joto, the key you brought?"

"Mr. Genda lent it to me, and I took his commission."

Gao Cheng pushed open the door and walked into the entrance first, and was attracted by the shoe prints in the corridor at first sight, and took out the shoes in the shoe cabinet in the entrance and tried them, and the shoe prints of Xuantian were about the same size.

"Gentian lives in such a big house alone......"

"Well, after his father died, he lived with his mother, and I heard that his mother also died last year."

The bow chief changed into slippers in the hallway and frowned at the shoe prints.

"These shoe prints are all from Gentian?"

"It's the same as I thought," Uncle Maori followed Conan to take out mud-covered socks and a shirt with burnt marks from the trash can next to him, "Bow Chief, Genda said that there was another one who set fire to himself when his sleepwalking was severe, and his words may be true......"

"It's too early to say that," Gao Cheng stood up and said, "Maybe this is also the hands and feet of the real murderer......

Now the most critical alibi has been explained, and that is the automatic time-delay ignition.

In addition, he has roughly asked about the motives of several suspects, the feng shui master Zeng I was threatened by the deceased Mrs. Ryoko with a cheating video, and the female soothsayer Quan Teng was able to get a large inheritance from her recently deceased father after Ryoko's death, and the will was to leave the inheritance to the person who inherited the surname of Zhujiao, so originally only Ryoko, who recruited a son-in-law, could get the inheritance......

As for the son-in-law, the psychiatrist Zhu Jiaoming, although he will not get an inheritance because of his wife's death, he is not without motives.

I heard that Zhu Jiaoming has always wanted to demolish the house and build his own hospital, but Ryoko, who has the ownership of the house, does not agree, and it is very likely that Ryoko will know about Ryoko's cheating......

The real murderer should be one of these 3 people, yes.

Gao Cheng's fingers tapped his eyebrows, and the details of the front and back flashed in his mind.

There are also a few strange suspicions.

At first, Mrs. Ryoko entrusted Nanchuan to investigate suspicious characters, but when the uncle replaced Nanchuan and asked to go to Zhujiao's house, Mrs. Ryoko suddenly changed her tone.

In addition, there is a small cushion that Mrs. Ryoko clutches tightly in her hand before she dies, which seems to be the stuff of a fortune teller...... This does not mean that the murderer is a soothsayer.

Wait a minute......

Mrs. Ryoko shouldn't have seen the murderer set up an automatic ignition device, did she know in advance who the arsonist was, so she suddenly changed her tune?

"Hey, Joto," Hattori exclaimed, looking through the shoe cabinet for a moment, "come here!" ”

"Huh?" Conan followed Gao Cheng to Hattori's side suspiciously.

"Any questions?"

"Look, this is the receipt of the phone bill on the shoe cabinet, isn't it strange that it uses so much 30,000 yuan a month? Gentian's guy doesn't look like he's going to talk on the phone a lot. ”

"Hmm," Conan nodded, "Xiaolan often talks to the garden on the phone, but the phone bill is not so much......"

"So," Hattori thought to himself, touching his chin, "and the same as the Hazuna fool, who often makes long phone calls, why do women like to talk so much?" ”
