"I've discovered something very important, maybe I know who you are." I say.

Zheng Ming was stunned: "Do you know who killed Su Hongtao?" ”

I nodded and said, "If I'm not mistaken, the murderer should be Liu Xinghe." ”

When Zheng Ming heard this, he knocked on the door suddenly. But no one answered in the house, so Zheng Ming went to ask the apartment administrator again: "Do you have the key to this room?" ”

The apartment manager was a little embarrassed and said, "Yes, there is, but it must be him who takes it, otherwise it ......."

Zheng Ming was a little angry and said, "Do you know who he is? He may be a murderer, and I have already run away! ”

When the apartment administrator heard Zheng Ming say this, where did he dare to talk more, he immediately took the key and opened Liu Xinghe's door.

However, Liu Xinghe was not in the house, the house was in a mess, looking at it like this, Liu Xinghe did escape.

"I'll contact Captain Zhou immediately and ask him to send someone to arrest Liu Xinghe." Zheng Ming said.

I waved my hand and said, "Don't embarrass him, even if Captain Zhou arranges it, Liu Xinghe may not be able to be arrested." ”

"This kid doesn't know where he has gone, you can't expect the two of us to get him back, right?" Zheng Ming said very anxiously.

Su Baitao took it and said, "How can it be the two of you?" If it is true that Liu Xinghe killed his sister and let him run to the ends of the earth, I will find him and let him pay for his sister's life! ”

Zheng Ming turned to me and asked, "How do you know that it was Liu Xinghe who killed Su Hongtao, and we didn't see anyone with him." ”

"You come here." I pointed to the ground in front of the door: "There are two distinctly different marks on the ground, what do they mean?" ”

The two of them came over to take a look, and Su Baitao said: "It means that the smooth part has been cleaned by someone, and according to my experience, it should still be cleaned with a vacuum cleaner." ”

"That's right, do you remember when we asked the apartment manager if he noticed anything suspicious, and what he said?" I asked.

The two men went to look at the apartment manager again, and the administrator quickly repeated: "I said, I said that on the night of the crime, I heard a sound similar to that of an electric motor. ”

"I think if you hear the sound, it's caused by a vacuum cleaner." I say.

"Even if that's the case, how did Liu Xinghe kill Su Hongtao, don't forget, this is a secret room, the whole room is closed, and Su Hongtao died of poisoning...... Zheng Ming couldn't figure this out.

After thinking about it carefully, I said to them: "It is very likely that the incident happened at that time, after Liu Xinghe fell asleep in Su Hongtao, he first put the seal halfway on the four sides of the door, and then turned on the gas switch. Then, Liu Xinghe walked out of the room and closed the door tightly. Outside the door, use the suction port of the vacuum cleaner to align the door crack, turn on the switch of the vacuum cleaner, and the remaining half of the seal will be sucked by the vacuum cleaner, so that it can be attached to the door and door frame. ”

Zheng Ming suddenly realized: "No wonder there is a seal on the door of the room, the reason is here." ”

"Liu Xinghe tried to use this method to create the illusion of Su Hongtao's suicide, but he still made a mistake and revealed his flaws." I say.

"I don't know where he will go, and I must not let him go easily." Su Baitao said.

I asked her, "Do you know where Liu Xinghe likes to go the most?" ”

Su Baitao frowned, and after thinking about it seriously: "He always seems to go to the zoo." ”

"Zoo? Didn't you go there once last week? I said.

"Yes, we went there once last week, and I know they come to the zoo a lot. It is said that Liu Xinghe is very familiar with the animals in the zoo, and some animals have become good friends with him. Su Baitao said.

When Zheng Ming heard this, he gritted his teeth and said, "This guy got very close to the animals, and in the end he became inferior to the beasts. ”

"Although I know his method of killing, I do not know his motive for killing. White Peach, do you know why he killed your sister? "I think now in addition to Liu Xinghe, only Su Baitao can explain.

Su Baitao thought for a while and said, "Maybe, it may have something to do with an ugly woman." The woman was a rich woman, not very good-looking, but covered in gold and silver jewelry. The rich woman fell in love with Liu Xinghe, her sister was a little angry, and she also went to laugh with other men, the conflict between the two intensified, and they quarreled last time. I think that this time Liu Xinghe killed his sister, maybe it was also because of that rich woman. ”

I reacted immediately: "You said that the rich woman is ugly and covered in gold and silver jewelry?" Do you have a picture of her and don't know her name? ”

Su Baitao saw my appearance and wondered: "Why are you so excited when you talk about it, you know her?" ”

"I suspect she's my enemy, but I can't be sure." I say.

Su Baitao opened her phone and found a photo from the photo album of her phone: "She is the rich woman I said, the last time she was with Liu Xinghe, I secretly took a photo." ”

When I looked closely, it was the alchemist!

"Sure enough, it was her, and she was secretly doing evil. Even if she didn't do anything to me, I wouldn't let her do anything bad. I said.

Zheng Ming said: "Let him like animals, let's go to the zoo to find it." ”

"How can a murderer go to a zoo at such a time? Wouldn't that be self-defeating, and the police would easily find him? I shook my head.

Su Baitao seemed to remember something, and said, "I know a place, maybe Liu Xinghe will go there." ”

"Oh? Let's talk about it. I hurriedly asked.

"It was a rich woman's villa in the suburbs, and I heard from my sister that Liu Xinghe would sometimes go there to find a rich woman." Su Baitao also added: "There are a lot of animals there, all of them are strange guys, I don't even recognize them." ”

Zheng Ming couldn't wait to say, "Then what are we waiting for, we must arrest that guy back now." ”

Under the guidance of Su Baitao, we came to the vicinity of the villa when it was dark. It is indeed a suburb and there are no other houses within 100 meters of the villa.

When you get close to the villa, you can smell a strong smell, which is obviously from an animal, and it smells disgusting, and it is incompatible with the tall villa in front of you.

At the back of the villa there was a large shed, and there were strange cries coming from it, presumably in which the animals were located.

"Let's go around to the back and see what's inside the shed." Zheng Ming came to curiosity.

I also wanted to take a look, so the three of us took advantage of the darkness to go to the shed, and the smell of animals became even stronger.

"I don't know how he has such a hobby." I frowned

"Maybe this guy is also suspected of trafficking in protected wild animals, I'll see what is in the shed." Zheng Ming spoke, as if he was glancing at it in a shed.
