last case

When Xie Jibai heard Tang Xin's words, his spine instantly felt chills. He reached out to touch the teapot, regardless of the fact that he was not wearing gloves and the teapot was covered with blood.

The milky white teapot is still hot, and the temperature is not too low.It was obviously a hot feeling, but when Xie Jibai touched it, he shivered fiercely.

"The murderer just left?" Xie Ji Bai couldn't help looking at the door, but they didn't see any suspicious people during the process of taking the elevator up.

Just a little...

Tang Xin saw Xie Jibai's hand, his slender fingertips were stained with a little blood, which looked extremely eye-catching.

Tang Xin took off the gloves, then took out a tissue from his pocket, held Xie Jibai's stiff hand, wiped off the blood, and said, "Let's wait for the boss and the others to come."

Xie Ji Bai nodded stiffly, feeling that his blood-stained fingers just now seemed to be burned, and he didn't take his hand out of Tang Xin's hand.Tang Xin's hands are big, his body temperature seems to be a little low, his joints are well defined, and he is very strong when holding his hand.It didn't make Xie Ji Bai feel sick and uncomfortable, it was just a little awkward, but it was far from as bad as he imagined.

Chen Wanting and the others rushed over quickly after receiving the call. When they entered the room, they were all taken aback when they saw the dead body. Although they were prepared, this scene was still very bloody.

"Xiaobai?" Chen Wanting immediately walked to Xie Jibai's side and asked, "Are you okay?"

"Boss, I'm fine." Xie Jibai said.

Chen Wanting nodded and breathed a sigh of relief. He knew that Xie Jibai must be uncomfortable seeing this kind of scene, but Xie Jibai's complexion was much better than before.

There was a lot of blood in the room, and it was difficult to collect evidence.Tang Xin had already looked at the corpse in general before, so he asked his assistant to help carry it away, so that it would be better to see it on the spot.

The deceased's name was Sun Xueling, who was Zhou Penggui's senior sister when she was in college, and now she is the HR manager of Zhou Penggui's company. Her husband had passed away for two weeks, and the rest was nothing special.

After collecting evidence, they generally learned about the situation from their neighbors.

Neighbors said that Sun Xueling was quite a polite person, but she was busy with work and her neighbors didn't see each other often. A few days ago, her husband died suddenly, but I heard that Sun Xueling had been haggard a lot recently, and there was nothing strange about it.

Not long ago, Sun Xueling's neighbor was also at home, but they didn't hear anything.

After everyone returned to the bureau, Xie Jibai was going to monitor the elevator in that building.Both elevators are monitored, but no one drives the elevators, and they are used 24 hours a day.

It is summer now, and according to the current weather conditions, it will take about an hour and a half for the scalding hot water to cool down.

Xie Jibai felt that this might be a key condition. Before Tang Xin gave the autopsy results, they could at least check the elevator monitoring based on this.

Xie Jibai played the elevator surveillance, and then selected the video from the two hours before they found the body to view.

Due to the situation that the elevator is occupied by decoration, the number of times the elevator runs is not many, and there are many people every time.

After watching for a long time, Xie Ji Bai became a little anxious, because he didn't find any suspicious person.Perhaps the murderer didn't actually use the elevator, but climbed directly to the 21st floor.

Xie Ji Bai was a little annoyed, and soon, he saw the shadows of himself and Tang Xin in the elevator monitor.The monitoring is installed in the upper right corner of the elevator, and it can take a little distance outside after the elevator door opens, but it can't take a long distance.

At that time the elevator door opened, Xie Ji Bai and Tang Xin were standing outside among the crowd waiting, and the people from that elevator came down crowded.

Xie Ji Bai suddenly quickly pressed the keyboard and stopped the recording.

The video on the screen is frozen, and the black and white image is really not clear.Xie Ji Bai stared at the screen tightly, with a serious expression on his face.

"What's the matter, Xiaobai?" Seeing his expression, Chen Yancai walked over and said, "Is there any problem?"

Xie Jibai pointed to the screen and said, "The crow..."

"Ah?" Chen Yancai's eyes widened immediately. After searching for a long time, she suddenly called out "Ah" and said, "It really is!"

The others gathered around and stared at the screen carefully.

There are a lot of people on the screen. Among the group of people, there is a man wearing a long trench coat and a hat with his head bowed. He seems to be wearing a little too much, which looks quite unnatural.However, this is not the point. The point is that there is a crow-shaped collar pin on the neckline of his clothes.

The surveillance was not very clear, so Xie Jibai and the others couldn't be sure if the crow tie pin was exactly the same as what they saw before, but the shape of the tie pin was very similar, which was already very suspicious.

Xie Jibai recalled the situation at that time, because there were too many people, so he didn't notice this man at all, and had no impression at all.

He looked back at the elevator monitor just now. This man did not go up from the elevator on the 21st floor, but from the [-]th floor.

Because the floor was relatively high, after he entered the elevator, the elevator was quite empty.He walked in and stood at the rear corner. His shadow immediately entered the blind spot of the camera, and he couldn't see clearly.During the whole process, the camera did not capture the man's appearance.

"This person is very suspicious." Liu Zhihui said, "He seems to be avoiding the camera on purpose."

"But he took the elevator from the eighteenth floor." Chen Yancai said, "Could it be just a coincidence."

A coincidence is possible, but Xie Ji Bai believes that this is a cunning suspect.He knew the location of the surveillance camera, and he was afraid that the surveillance camera would capture him, so he took the stairs down a few floors after the murder, and then took the elevator.

Chen Yancai said distressedly: "Although what Xiaobai said is reasonable, I think it is also unreasonable. Then he just walks down the corridor. There is no surveillance there. Just walk down. Why do you need to take the elevator again?"

Qin Xu rarely said, "Because he has to take the elevator, otherwise he won't be able to get down."

"I know this." Liu Zhihui said in detail: "When we rushed over just now, I saw that the elevator never came, so I wanted to just climb up to the [-]th floor in one go. But an old man told me that the stairwell is not allowed, Because of the decoration, there are a lot of things piled up there, there are big cabinets, and the small stairwell is sealed, and it is impossible to go up or down."

If this is the case, it can indeed explain why the suspect walked down the stairwell and then changed to the elevator.

"It seems that everyone has a clue?" Tang Xin walked in and said.

"How about you?" Xie Jibai asked.

Tang Xin said, "I just came here to tell you guys."

Tang Xin took the corpse for an examination, as well as the pot of blood rose tea that was held under the arm of the corpse.

Tang Xin said: "I tested that pot of blood rose tea, there is indeed blood in it, but..."

Everyone looked at him, but Tang Xin stopped in the middle of speaking, and everyone had a bad premonition instantly.

Xie Ji Bai couldn't help but said, "It doesn't match the DNA of the previous two times at all?"

Tang Xin nodded and said, "Yes, it's the same as the previous two cases, it's brand new DNA, and I don't know whose blood it is."

For a moment, everyone had a headache. They didn't know what the murderer was going to do now. Now there were three blood roses, one dried flower, one fresh flower, and one scented tea. They were all dyed with different blood.

Chen Yancai couldn't help but glanced at it. She had just bought scented tea not long ago, and she no longer had the slightest desire to drink it.

Tang Xin said: "As for the other circumstances, I won't know until I finish the thorough autopsy. However, depending on the situation, the deceased Sun Xueling should have been directly pierced through the neck by a sharp weapon, and there was no other trauma. I have not taken any medicine, or been poisoned, and I will continue to check."

Chen Wanting nodded and said, "Okay, you can go."

After Tang Xin reported the situation, he went back for the autopsy.

Everyone was silent for a while, feeling that things were getting weirder and weirder.

Qin Xu suddenly said, "I suddenly thought of a question."

"What's the problem?" Liu Zhihui asked quickly.

"The location of the fatal injury of the deceased." Qin Xu said.

When he mentioned this, there was such a question in everyone's mind.

The deceased died from an injury to the back of the neck. Although the room was bloody, there were no traces of a fight. It is very likely that the murderer killed the deceased with a knife after entering the room while the deceased was not paying attention.

Then there is a big problem.

How did the murderer get into the house without being noticed by the deceased?

Could it be that Sun Xueling is at home alone and has no habit of closing and locking the door at all?Or, the murderer was someone Sun Xueling knew and had the keys to Sun Xueling's house.

In addition, the biggest problem is the motive of the murderer.

The deaths of Zhou Penggui and Sun Xueling were very strange. Blood roses were found at the scene of the first crime, and blood roses were also found at the scene of the second crime, but in slightly different forms.They had to believe that it was the same murderer who committed the two crimes.But what is the murderer's motive?

Xie Jibai continued to watch the video, and Chen Yancai went to check Sun Xueling's connections, and it turned out that it was actually quite normal.

Sun Xueling is just an ordinary white-collar worker, going to school, working, and getting married.There are no enemies or enemies, only friends and ordinary people. Coincidentally, her parents have passed away long ago.

When Tang Xin came back from the autopsy, he didn't expect that there were so many people in the office, except for Chen Wanting.

Tang Xin said: "It's really rare, why are you all here? Are you going to work overtime all night?"

Chen Yancai clattered on the keyboard and said, "I'm really sorry for disturbing the time between you and Xiaobai."

Tang Xin smiled, did not deny it, and asked, "Boss has gone back?"

"No, I'm answering the phone outside." Xie Ji Bai raised his chin and said.

Through the glass, Tang Xin saw Chen Wanting leaning against the wall in the tea room and talking on the phone.

Tang Xin said: "I guess I must be calling Boss Su."

"It must be." Chen Yancai said, "As soon as the phone rang, I knew it."

Liu Zhihui opened his eyes wide and said, "Ah? Sister Chen, you still have this supernatural power."

"Bah, what a special function." Chen Yancai said: "Xiao Liu, you have to watch carefully, didn't you hear it? Boss's cell phone, Boss Su called a special cell phone ringtone, and we ring him a very ordinary ringtone .”

"So that's how it is." Liu Zhihui suddenly realized.

Tang Xin hadn't noticed it before, and he felt a sudden realization. Then he took out his mobile phone and set a special ringtone for Xie Jibai's phone number.
