Police Detective

Detachment Zhao's reaction surprised Bai Song, because the first police officers who went to the scene were from the police station. Detachment Zhao is not responsible for these police problems, but he is worried about these police officers. This shows that Detachment Zhao still attaches great importance to the cases of his own branch and cares enough about his comrades.

The case went on until late at night, and Bureau Wei also came over. Experts, criminal department bosses and others from the city kept coming over, all with the same situation.

Because the decomposition products of cyanide cannot be found, there are two problems. The first is the hydrogen cyanide liquid, and the second is that someone took away the residue of the decomposed sodium cyanide.

No matter which statement is made, the surveillance video does not support it.

Of course, it would be hard to say if other personnel in this building committed the crime.

The fourth floor where Xiao is located is mostly rental housing, but this is not the case on other floors. There are basically no videos, and some of them are in disrepair.

There is a video recording of the entrance and exit of this building, so it can be determined that no outsiders came in when the crime occurred.

If the suspect has been lurking for several days, or even for more than ten days, exceeding the coverage of the camera, then the suspect must not have gone out yet.

This statement is unlikely. There are many residents in this building, and ten days in advance is indeed an exaggeration. Someone will definitely find out. Everyone would rather believe that this person climbed the wall and climbed in through the window to avoid surveillance.

After investigation, no trace was found.

"Huadong, if it were you, how could you make the traces so good?"

It's past three o'clock in the morning and everyone needs to rest. We will have to fight again tomorrow morning.

There are a few people in the detachment and the main team who were not busy with cases before. They are now on night duty in case there is information that cannot be disseminated in time.

The five people from the fifth team were arranged into a small room with only two bunk beds, with a folding bed in the middle. There are a lot of people, which is already a very good condition.

They were all tired, but they couldn't sleep.

"I can't do it." Wang Huadong shook his head: "But someone can do it, Master Hao should be able to do it."

"Not necessarily," Liu Shuyuan said, "I also went to see the scene on the stairs. I feel that it is not difficult to avoid being discovered in the chaos."

"Anyway, I don't think I can do it." Wang Huadong said again.

"That means I'm a layman." Liu Shuyuan said that he still listened to Wang Huadong: "This case is too difficult. It's all Wang Liang's fault."

"Why are you blaming me? I don't want to have a case all the time. You guys are looking forward to something to do every day, but when things happen, you blame me?" Wang Liang said angrily: "I can't live this life."

"Your ability to plant flags in reverse is too strong." Liu Shuyuan said.

"Depend on!"

It's useless to say anything else. This case is really difficult to handle.

At this time last night, everyone was sleeping, and when they got up in the morning, they were still complaining about the pain in their balls. After a short time, they were slapped in the face by reality.

"Master Hao's statement is no different from yours, right?" Bai Song asked.

"Well, but Master Hao is a trace expert, not a footprint expert. He can't be 100% sure about the situation in the corridor. It's just that there is no suspicious situation found so far. There are no traces of struggle in the corridor. It's as if Xiao was poisoned after arriving in the corridor. , then fell to the ground, fainted, and then died." Wang Huadong said.

"Isn't he a footprint expert?" Liu Shuyuan asked curiously.

"It can be counted, but it's not the top one. What he's better at is traces." Wang Huadong explained.

"I don't quite believe that this kind of thing could be done by a group of masters. I almost checked out Xiao's kindergarten affairs and didn't offend anyone." Bai Song said, "That's really weird. Could it be that he came back?" I inhaled some cyanide on the road home, and then over time, I got poisoned?"

"It is true that the content in his body is not high, but this is not realistic. Mild cyanide poisoning can be relieved on its own. If it is moderate or severe, it is impossible to go home and eat." Sun Jie said.

"It's too evil. Go to sleep." Bai Song covered himself with a quilt: "This spring bed is really short."

At around six o'clock in the morning, everyone got up one after another.

Sleeping for three hours is considered normal when you are busy with a case. Everyone is recuperating during this period. It doesn't feel like doing this on the first day.

Xingang Branch Criminal Investigation Detachment.

"Another person died?" Bai Song was frightened when he heard the news: "Why didn't you tell us?"

"Detective Bai, don't worry, this person has been arrested." The local detective was a little panicked when he saw Bai Song's momentum.

"He's been caught!" Wang Liang suddenly jumped in front of the man, "How did you catch him?"

"Captain Wang, please let go, it's not the same thing."

This has been a really troubled winter.

Last night, there was a fight at a nearby construction site over wage demands. Then in the middle of the night, there was a bit of a commotion, with several people fighting with weapons, and one person got a little ruthless and accidentally beat a foreman to death. The construction site is inherently dark, and it is really dangerous to use those "weapons" on the construction site.

The suspect tried to run away, but he was caught within two hours of calling the police, and the trial was almost complete.

"There have been murders for two days in a row. What's the expression on your Zhao detachment's face?" Wang Liang was a little gloating, "I thought these two were the same case."

"Death is not a good thing after all." Bai Song felt that his happiness was in vain: "Let's go get something to eat first. From the looks of it, there must have been no progress in yesterday's case."

The canteen was not closed at night because another case broke out yesterday, and all the people on duty in the detachment went to arrest people. When they came back, they bought a lot of hamburgers and put them in the canteen, so there was no need to finish them all at this time.

In the middle of the night, the only ones available that are open 24 hours a day.

At this time, the master chef of the cafeteria came early, cooked porridge, and prepared flatbreads and fried dough sticks. The five of them ate briefly, chatted with several people in the cafeteria, and got more clues.

The New Year's Eve here has always been uneasy over the past few years, but murder cases are not bad. There are really a lot of fights and people asking for wages. They can be encountered in every police station every week. Looking at the entire branch, they happen every day.

"The Zhao detachment is now under much less pressure." Bai Song said: "They have a new case, and they arrested someone so quickly. Their abilities are still here. From the looks of it, it is estimated that starting today, It is our responsibility to investigate this cyanide poisoning case."

"Let's chew the hard bones, there's nothing wrong with that!" Wang Liang patted his chest.

"Okay, I'm still confident anyway!" Bai Song said: "It's only been a day, but I don't believe it. The murderer is smarter than all of us put together."

"Yes, come on, investigate!" Sun Jie nodded: "Bai Song, tell me about the investigation plan."

"Um" Bai Song paused and said, "We will have a meeting later to listen to the leadership's opinions."
