The reaction of the Zhao detachment surprised Bai Song a little, because the police who went to the scene first were from the police station. The Zhao detachment is not responsible for the problems of these policemen, but he is worried about these policemen, which can show that the Zhao detachment still attaches great importance to the cases of its own sub-bureau and loves its comrades in the sub-bureau enough.

The case went on late at night, and the Wei Bureau also came, and there were constantly experts, bigwigs from the criminal department and other people in the city, all of which were exactly the same situation.

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

Either way, the surveillance footage doesn't support it.

Of course, it's hard to say if it was someone else in the building who committed the crime.

The fourth floor where Xiao is located is mostly a rental house, but this is not the case on other floors, and there is basically no video, and several of them are in disrepair.

The entrance and exit of this building were videotaped, and it can be determined that no outsiders entered at the time of the crime.

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

This statement is unlikely, there are more residents in this building, and it is indeed an exaggeration to be ten days in advance, and it will definitely be discovered. Everyone would rather believe that this person climbed the wall and climbed through the window to avoid the surveillance.

After investigation, no traces were found.

"Huadong, if it were you, would you be able to make the traces so good?"

At three o'clock in the morning, everyone has to rest, and tomorrow morning we have to fight again.

There are a few people in the detachment and the general team who have not been busy with cases before, and they will be on duty at this time, in case there is information that cannot be transmitted in time.

The five members of the fifth team were arranged in a hut with only two bunk beds, with a folding bed in between. There are a lot of people, which is already a very good condition.

I was very tired, but I couldn't sleep.

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

"Not necessarily", Liu Shuyuan said: "I also went to see the staircase scene, and I feel that it is not difficult not to be found in the chaos." ”

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

"That's my layman. Liu Shuyuan said that he still listened to Wang Huadong: "This case is too difficult, and Wang Liang is to blame." ”

"Why do you blame me? I don't want to come to the case all day long, you look forward to something to do every day, but when things come, blame me?" Wang Liang said angrily: "I can't live this day." ”

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

"Damn!"

...

It's useless to say anything else, this case is really uncomfortable.

At this time last night, everyone was sleeping, and when they got up in the morning, they were still complaining that the idle eggs hurt, and it was only a long time before 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, and he is not 100% sure about the situation in the corridor, but he has indeed found no suspicious circumstances at present. There was no trace of a fight in the corridor, 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 an expert in footprints?" asked Liu Shuyuan curiously.

"It's okay, but it's not the top, he's better at traces. Wang Huadong explained.

"I don't really believe that this kind of thing will be done by several masters, Xiao and I are about to check all the things in his kindergarten, and I haven't messed with anyone. Bai Song said: "It's really evil, could it be that he inhaled some cyanide on the way home, and then after a long time, he was poisoned?"

"The level in his body is indeed not high, but this is also unrealistic, mild cyanide poisoning can be relieved on its own, if it is moderate and moderate, it is impossible to go home and eat. Sun Jie said.

"It's so wicked, sleep. Bai Song covered the quilt: "This spring bed is really short." ”

...

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

Sleeping for three hours is considered normal when you are busy with cases, and everyone is recuperating during this time, but it doesn't feel like this on the first day.

Criminal Investigation Detachment of Xingang Branch.

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

"Inspector Bai, don't worry, this person has already been arrested. The local little criminal police were a little panicked when they saw Bai Song's momentum.

"Someone was caught!" Wang Liang suddenly jumped in front of this person, "How did you catch it?" ”

"Team Wang, you let go, it's not a thing..."

It's been an eventful winter too.

Yesterday evening, there was a fight at a nearby construction site over a wage. Then in the second half of the night, there was a bit of a fierce commotion, several people fought, and one person was a little ruthless, and a foreman was killed by mistake. The place on the construction site is already dark, and the "weapons" on the construction site are really dangerous.

The suspect wanted to run away, and he was caught within two hours after calling the police, and the trial was almost over.

"There have been murders for two days in a row, what is the expression of your Zhao detachment?" Wang Liang gloated a little, "I thought these two were the same case." ”

"It's not a good thing to be dead. Bai Song felt that he was happy: "Let's go eat something first, looking at this, there must be no progress in yesterday's case." ”

The canteen didn't close at night, because there was another case yesterday, and the detachment on duty went to arrest people, and when they came back, they bought a lot of hamburgers or something and put them in the canteen, and they didn't have to finish eating at this time.

In the middle of the night, the only ones you can buy are those that are open 24 hours a day.

At this time, the master of the canteen came early, boiled porridge, flatbread and fritters, and the five of them ate a little, chatted with a few people in the canteen, and got more clues.

The New Year's Pass here in the past few years has always been unpeaceful, the murders are okay, there are really many fights and salaries, every police station can encounter them every week, and the entire sub-bureau looks at it every day.

"Their Zhao detachment is much less stressed. Bai Song said: "They have a new case, and they arrested people so quickly, and the ability of the people is still here." Looking at this situation, it is estimated that starting today, we will have to be responsible for investigating this cyanide poisoning case. ”

"We gnaw on the hard bones, there's nothing wrong with it!" Wang Liang patted his chest.

"Okay, I'm still full of confidence anyway!" Bai Song said: "It's only been one day, I don't believe it, the murderer is smarter than all of us combined." ”

"Yes, come on, check!" Sun Jie nodded: "Bai Song, let's talk about the reconnaissance plan." ”

"Boom..."Bai Song froze for a moment: "I will have a meeting in a while to listen to the opinions of the leaders..."
