After the old man left, Ace called a young man at this time, he was also the person who appeared before and after the crime, this young man was wearing a white dress, a pair of black pants, and slippers, Ace looked at his dress as a poor boy, Ace was also slightly stunned, and began to ask the young man. "You also went to the third floor on the day of the fire?"

"Yes, I went to pay the rent and went to the third floor, which was the wrong way." The young man spoke.

"When are you going to the third floor and what are you doing?" Ace looked at the man carefully before asking him.

The young man replied to the trump card: "At two o'clock in the afternoon, I went to pay the rent, I went the wrong way, I went to the second floor, I looked at my mobile phone at the time, I didn't pay attention, and I went to the third floor." ”

"Is that so?" Ace stared at the man in front of him, trying to see something from his expression, but there was no way to see it, and no one proved what he said, but Ace was asking for clues this time, not looking for a suspect, and now the suspect has become a complex suspect, and now he doesn't know who to go to.

"Comrade policeman, it's really like this, I just went the wrong way, the landlord can testify, it was he who called me at that time, and I went to pay the rent. The young man said on this occasion, and he also called the landlord out to testify.

Ace now understands a little, the two people they inquired about today seem to be busy in vain, they didn't ask anything out of their mouths, but the old woman, to provide a stranger to come to room 309, can't find anyone to go to the hostess of room 309, you can ask about the situation, but now you have to pay special attention, if this man is a suspect What is the relationship between him and the owner of room 309, this must be fully prepared, otherwise to ask the person in room 309, it will be a no, so the gains outweigh the losses.

Ace thought about it for a long time, and planned to check the security uniform, and if he wanted to find this person, he had to find the owner of room 309. "Let's go to the people in room 309 and ask this man in security uniform."

"I've already asked, the hostess of room 309 said, it's just his ordinary friend, there is no problem." Jin Shan said lightly, just when the ace was thinking there just now, Jin Shan had already called to ask, and the ace opened his eyes and looked at Jin Shan. "So fast, what else did she tell you?"

Jin Shan smiled slightly and looked at the trump card, his old friend, everything is good, and the bad thing is that he will ask the root to the end. "Even though she said that, I think she's lying, and I can conclude she's lying." Jinshan decided that the owner of room 309 was lying.

"Could it be that this man in security guard has anything to do with this case, or has nothing to do with it, why do you think she's lying?" Ace asked Jin Shan bluntly why his judgment was like this"

"I just called and asked, at first the eighth sister in room 309, said that she didn't know this man in security uniform, I later said that on the day of the fire, the man in security uniform went to her house, under my aggressiveness, she said that the person was her friend, I felt very strange, I always felt that she was lying."

Jin Shan heard the words of the eighth sister, where can he hide Jin Shan, this kind of thing, Jin Shan has experience?

Ace touched his chin and thought. "You mean the security man, we're going to investigate."

Jin Shan made an OK gesture, which means that it is not necessary to check. "Needless to say. Must check. ”

Three hours later.

"Comrade policeman, if you have something to ask, I still have to work, after a long time, I have to calculate the salary for me." The man in the security uniform was called to them, the man's expression was a little ugly, he was called here by the police, he was very unhappy, his speech was a little discordant, and his attitude was not harmonious.

Ace winked at the man in the security suit and looked at him in surprise, his tone a little rude. "We're just asking you to ask a few words, don't be so careful."

The man in the security uniform kept a straight face, so as not to give face to the ace, this person didn't take them seriously at all. "You have something to ask, we don't have time, don't you delay my time?"

Although the man in his security suit had a bad attitude, Ace smiled harmoniously at the security man, and then immediately followed. "On the day of the fire in this building, you came to the house of the eighth sister in room 309, but did you have such a thing?"

If people don't know, unless they don't do it, the man in the security uniform knows this truth and answers the trump card very happily. "Yes, I went at eight o'clock in the morning and left at half past eight, and I left with my eighth sister."

Ace thought for a moment, then asked. "What is the relationship between you and the eighth sister, you have to be honest, since you went out, there have been two strange things, the eighth sister's house was broken into the house, and then the gas tank was tampered with, resulting in a fire, and the more serious thing is in the back, room 308 next door is still dead, not burned to death, but he killed."

The man in the security uniform listened to what the ace said so much, and he didn't care. "What does this have to do with me, I'm good friends with Eighth Sister, what's wrong, you also ask this."

Ace looked at the man in the security uniform and immediately complained about him, this person is simply unreasonable, and it is rude to speak. "Since you have such an attitude, you go back first, and we will call you if there is something?"

Ace hated this person when he saw it, and asked like this, and the more he asked, the more he looked at this person's attitude, hey.

The man in the security uniform looked at the two of them, turned around and left, so as not to pay attention to them. "Comrade policeman, don't ask me any questions, I'm just ordinary friends with Eighth Sister."

Jin Shan looked at the back of the man in the security uniform, and he was still blaming the ace in his heart, why did he let him go. "Detective, why did you let him go like this, I don't know what your intentions were?"

Ace shook his head and said. "Look at his attitude, the more he is here, the more I feel angry, I think this person has a bad mentality, and there is no way to prove that he is a suspect."

Jin Shan analyzed this. "Could it be that the man in the security uniform and the eighth sister killed the deceased of 308, and then turned the gas canister on their mobile phone, they did this to create chaos and make it impossible for us to find out, or they just tried to burn the body."

Ace himself thought about this problem and always felt that it was wrong. "They left at half past eight in the morning and came back at night, they didn't have the time to commit the crime, even if they could fake a person who had picked the door lock, so that we thought someone had entered his house, but the time of the deceased's death, it couldn't be faked, they did the crime."

Jin Shan analyzed. "Before, we had to separate these two cases to investigate, and we got them together again, to be honest, I don't know how to do it now, I can't do anything, and there is proof of this thing, it's hard to say clearly, not to mention that there is no monitor on the third floor, who knows if there are other people who have entered, and the two sons of the deceased have also been there."
