Any adult, even someone who claims to have a simple relationship, has at least a hundred related people. Maybe you think you only have three or five friends, but if you count your colleagues, clients, classmates, relatives and friends, and all kinds of people who have contact with each other, more than 100 people is really not much.

The situation of the game is the most chaotic, the players are from all over the world, even if it is a murder, it is impossible for all members of the union to send people on a business trip to get the transcript, and it has not been checked yet.

The people who had the battery stolen were also checked one by one, and some people did not call the police at the time, and then the police came to the community to ask someone to say that their battery was stolen.

Battery theft is different for different people. Some people don't call the police, feeling unlucky and unlucky, and they will change to a new one the next day, and some people will call the police, very angry, hoping that the police will arrest people as soon as possible.

One by one, most of the people are also ordinary people, and Bai Song can basically be sure that these people are indeed not killing.

There is no clue as to the origin of cyanide.

It's not that there isn't, it's too many!

This is the new port area!

In Tianhua Port, some warehouses actually store hundreds of tons of cyanide!

In addition to this, many factories have this thing, and there are many enterprises in Tianhuagang with similar qualifications. Without any other clues, directly investigating the source is no less than looking for a needle in a haystack.

The Zhao detachment has always relied more on graphic reconnaissance, and in recent days, the nearby videos have been exhausted, and no suspicious characters have been found.

However, it cannot be said that there has been no progress in the case at all.

Xiao used a slightly rusty key to open the door of his house. The keys are basically made of stainless steel or copper alloy, which is basically rusty, but it will still form a layer of oxide film on the surface after a long time.

The key Xiao used to open the door, after analysis, should not have formed an oxide film of this thickness during Xiao's fifteen days of detention.

If this can be analyzed, one can imagine the extent to which the on-site investigation has been.

Now, the furnishings in the house are basically untouched, but the investigators have searched all over to obtain as much evidence as possible on the premise of keeping the scene intact.

Now it is basically certain that after Xiao was arrested, the police took Xiao back to the house to check in order to prevent Xiao from hiding batteries in his residence. From the time the police left until Xiao died, no outsiders entered the house.

From a trace point of view, this should be called a "conclusion".

It can be seen from the situation of the key that this key is not commonly used by Xiao.

contacted the landlord, and the landlord also said that he had given Xiao two keys to the room, and now there is only this one, which means that the other key should be lost. However, it is not known when or under what circumstances it was lost.

At present, the largest suspected location of loss is the original intermediary company.

...

"I'm all tired", Bai Song opened a bottle of beer-flavored non-alcoholic drinks and poured them for everyone: "Use this as wine, today is a Christmas no matter what, everyone has worked hard." ”

"Yes, eat first. Sun Jie also raised his glass.

"Bai Song, do you feel that there is a drama in this case?" Wang Liang raised his glass and asked bluntly.

Bai Song shook his head.

"Huh, you actually shook your head?" Wang Liang said: "Since you joined the work, there has been no case that you can't solve." ”

"Who says there isn't? When I was in the office, there were still a lot of unsolved theft and fraud cases, and some of them just didn't have the conditions to be detected. Bai Song saw that everyone raised his glass: "Come, cheers." ”

Everyone clinked glasses, took a sip, and was silent.

"What's the matter, this is discouraged?" Bai Song looked at a few: "Do you remember the time I went to Shonan Province a few months ago, and I was busy for a month and returned without success?"

"Yes. Wang Liang's eyes lit up: "You mean, this case can also turn around?"

"I didn't mean that. Bai Song said: "Starting tomorrow, their detachment can also free up a few people who are busy with the murder case, it is only three days, after the golden period of solving the case, it is not so urgent, and it will be investigated slowly and carefully." At present, all the related people we are looking for have been found, and if the suspect is within the range of these people, he will definitely not run, and he will not dare to run. Whoever runs now is to increase our suspicions. ”

"Their Zhao detachment, who can't pee with us, always feels like they love to ignore it, and the case of Da Hei is very annoying to them. Wang Liang also had nothing to say and began to complain.

"This is a person with a story", Liu Shuyuan said: "Don't underestimate him, if he hadn't wanted to be the deputy director twice in a row, he wouldn't be what he is now." ”

"Isn't it normal to not be able to be? Wang Liang was slightly disdainful.

"It was supposed to be him. Liu Shuyuan glanced at Wang Liang.

Wang Liang opened his mouth and did not speak.

...

A few days have passed, and the situation is now that the vast majority of people have lost confidence in this case.

It's not that if you have the attention of a big leader, you will definitely be able to solve the case, if only it were really that simple. After all, leadership doesn't grow linearly with rank.

Several experts who came were also full of doubts about this case.

The city applied to the higher authorities for an expert group.

Footprint Specialists.

The corridor and the house have been completely sealed, and after the experts came, they conducted a thorough investigation, and finally came to the conclusion that no suspicious person's footprints were found.

Not only were no footprints found, but no traces of treated footprints were found.

This conclusion cannot be directly used as evidence, but for everyone, the death penalty can already be imposed on this case.

Don't ask, you just don't know.

The puzzle begins to ferment and gets bigger and bigger.

Once the case enters this state, there is a scene but the suspect cannot be found, which will attract widespread attention.

There has been a cordon here, and the media has long paid attention to it, and not only that, but other provinces and cities are also ready to participate in this case.

This is like Bai Song wants to lead the team to other provinces to participate in some cases, and if he can solve the case, he will have a very long face. Moreover, the experts on this case did not find any clues, and it is not a shame that people from other provinces did not find anything valuable.

Tianhua City not only agreed, but also expressed a warm welcome.

After Xiao's body was autopsied, it was thoroughly investigated and tested more than five times.

Approaching the end of the solar year, the mystery of this case is getting bigger and bigger, and even the dog breeding base in Mongolia has sent a police dog with a good sense of smell to help, but it is still nothing, but people have also said that if the police dog is sent at the time of the crime, there may be gains, and I don't know if it is for the sake of face.

Headache.
