Sister Liang said that although she is just a cleaner, the residents of the whole building are still very kind, such as the grandmother of 2602, as long as there are waste products at home, she must keep them.

The grandmother who was on the other side of the door got on the elevator and said she was going to buy groceries and left.

Sister Liang did the cleaning of the whole floor, and the door of 2601 was not closed.

She walked over and could be seen outside the door with a man sitting on the couch.

There was a knock on the door, but the man did not respond.

She thought the man was asleep and called out a few more times, but the one still didn't respond.

Sister Liang felt that something was not right, and when she walked in, she saw the man sitting on the sofa, his head drooping, and his face was like ashes.

As in the previous cases, the murderer was killed with a knife, and no valuable clues were found in the room except for the footprints of Sister Liang.

There was no trace of the murderer, and according to past experience, the murder weapon must have been a knife in the kitchen.

But Gou Tianming is a big man and a rich son, and there is no fireworks at home.

The kitchen is smooth, flat, not to mention knives, there are no pots and pans.

In case the knife doesn't come in the bureau, Pony and the bureau's forensic doctor Xu are on the scene.

Forensic doctor Xu said that the murder weapon should be the scalpel on the flower platform in the garden, and the cause of Gou Tianming's death was almost between 12 and 4 o'clock last night, and Liu Guang downstairs was also at this point in time.

Yi Tian was convinced of this, and for a forensic doctor who had been using a scalpel for a long time, he would not be wrong in judging that the murder weapon was the scalpel.

And Yi Tian understood that the colleagues in the trace laboratory department would soon find a fingerprint on that scalpel, and that fingerprint belonged to the person he was familiar with.

Wang Tong was stunned, and he sent a soul question to Yi Tian.

"Are these two cases the same murderer?"

Yi Tian's face was heavy and he sighed.

"Of course."

Wang Tong was stunned: "Is the murderer stupid?" The case upstairs is done seamlessly, but the downstairs is full of loopholes, do you want the police to find him quickly? Were the previous cases committed by the same murderer? ”

Yi Tian: "I think I already know who the murderer is." ”

Wang Tong was stunned: "Yi Tian, are you a god?" ”

"The murderer's target should be Gou Tianming, Liu Guang downstairs was just unlucky, and he met a murderer who was in a rather bad mood, which was a random killing."

Wang Tong: "Who is the murderer?" ”

Yi Tian: "You know this person." ”

Wang Tong had a question mark on his face: "If you don't sell it like this, you just tell me directly, it will make people's hearts itch." ”

Yi Tian: "Put away your curiosity!" I'm afraid that after you know the truth, my heart will itch and hurt, and I can't wait to know the result. ”

Wang Tong was unwilling: "I ......"

Yi Tian: "Follow me back to the bureau to find out." ”

Downstairs in the Garden of Fortune, he gave the car keys to Yi Tian.

"You go pick up the car, and I'll go to Liu Guang's scene to have a look."

Wang Tong turned around and went to the parking lot of the community.

At the scene of Liu Guang's crime, Liu Guang's body had been pulled away, and there was a large pool of dried blood on the edge of the flower platform.

In the grass where the bloody scalpel was found, not far away, a clown's nose was hidden in the grass.

The officers who came in the early days didn't pay attention to this clown's nose, after all, this thing is a hobby of children, and it is not uncommon in the grass.

He took the clown's nose out, pinched it in his palm, and put it in his trouser pocket.

He remembered the day before yesterday when he found the bag of clownnoses in her bedside table.

He took out the bag of clowns, still in the trash can downstairs, and watched the garbage truck take the bin away.

When and where did she get such a nasty thing?

In the interrogation room of the Public Security Bureau.

In case Dao sat calmly opposite Yi Tian, she remained silent. Wang Tong, who was sitting next to Yi Tian, was also silent, to be honest, he couldn't believe that the mysterious murderer last night was a colleague who had worked with him for many years.

Yi Tian spoke.

"Wan Qian, I said, as long as you confess, I will definitely help you."

Wang Tong echoed: "Yes, Wan Qian, I believe you must have a last resort, it was those fucked guys who threatened you, right?" You name it, justice can always triumph over evil, and I don't believe they can turn against the sky. ”

She shook her head, still silent, her eyes fixed on Yi Tian.

Yi Tian was anxious: "Wan Qian, what do you have to do to speak?" Tell me, there wasn't really any other mysterious person last night, it was you all the time, right? ”

She finally spoke: "Okay, Yi Tian, if I say it to help you, I'm willing to say it." ”

She glanced at Wang Tong, with a hint of love and pity in her eyes that people couldn't refuse.

"I'm sorry, Wang Tong, can I stay alone with him for a while?"

Wang Tong got up and walked out of the door of the interrogation room, and Li Ju, a guy who couldn't hold his breath, and one and two cakes were outside the interrogation room.

Bureau Li: "How's it going?" In case the knife has something to say? ”

Erbai: "Yes, how is it possible, in case she can't be the murderer, Team Yi must be mistaken." ”

Wang Tong has a special sense of decadence.

"Yes or no? There will definitely be a result, but I believe Yi Tian, he said that it must be. ”

In the interrogation room, in case of a knife, he glanced at Yi Tian.

"Can you give me a glass of water first?"

She gestured to the empty cup in front of her.

"Okay, I'll pour it for you."

"No, I'm going to drink yours, you still have half a cup in your cup."

Yi Tian hesitated, but she didn't mind, and directly took his cup and drank it all.

Then, she played with that particular cup, a somewhat comical Minion cup.

"What a ridiculous cup, she gave it to you!"

Yi Tian defaults.

"I don't understand, what's so good about her, she can actually harvest your heart in a short period of time, and I, for so many years, have been behind you, silently paying for you. But why didn't you see it? Yi Tian, are you blind? ”

Yi Tian sat down, took the cup in her hand, and stared at her closely.

"Say it! What did you do to her? ”

She smiled coldly: "Hmph, at this time, even if I am in prison, I am still towards her in your heart." You say, is it my sorrow, or is it her luck? ”

He gritted his teeth: "Say, what exactly did you do to her?" ”

Her face became more and more calm: "Hmph, no one has done anything to her?" This is her life. How did you feel last night when you saw her standing quietly outside the gate, looking at you with unfamiliar eyes? She's not as good as you think! ”

"You did it on purpose, right? deliberately stunned Lao Fang, made me aware of the ordinary, and then went to the gate to see her standing right outside the gate. ”
