Because they received a call from the detachment, the three of Bai Song first found a monitoring room to stay in. It was relatively quiet, and there were no cameras or recording equipment in the monitoring room.

This monitoring room is very weird. The big screen is a 65-inch TV that has just been changed, but the image is very unclear. Obviously, the camera did not change, just the display. There are obvious age differences between images and displays.

"Besides this, are there other main clues?" Bai Song was about to listen to the generation detachment to finish.

"Yes, the most important thing is that there is a driver who has an impression of this person. Because the driver chats with him, he doesn't speak, and he shows the driver an address and lets him drive over. The driver thought he was dumb, so he had the impression." , On behalf of the detachment said: "The driver successfully identified Lin Liang."

"What is the interval between the two cars?" Bai Song asked, "How long did he stay with Lin Qing?"

"There is no specific video of the place where the car stopped, but it can be roughly inferred that it will be minutes after he got off the car and took a taxi again", the detachment said: "It feels like there is something wrong with going there alone, and then left, even though He walks quickly and will not spend more than 5 minutes at Lin Qing's house."

"Then why did he go..." Bai Song thought for a while: "The driver who recognized Lin Liang, did he mention what Lin Liang was carrying in his hands?"

"He said no, he had the impression that Lin Liang only brought his mobile phone," the deputy said: "But cash was used for checkout."

"Then what is he doing this trip?" Bai Song felt puzzled.

"According to the judgment of Ouyang experts, two people at the scene committed a criminal act. This is definitely not possible within 5 minutes. So he should not be the murderer, the murderer..." Dai Detachment said: "We still suspect Li Ruibin and his son. ."

After the detachment team finished speaking, they found that Bai Song did not reply to him. Then he realized that Bai Song did not answer the question asked by him. He wanted to say something, but he didn't know what to say.

"Is he just going to take a look, no other meaning?" Liu Shuyuan said.

"That's too coincidental, right?" Sun Jie said: "This time is almost the same as the time of the deceased's death. It stands to reason that you can run into murderers at this time."

"This time is indeed a coincidence, it's a coincidence," Bai Song has a good memory: "Between the time he got off the bus and the time he got on the bus, it happened to be Lin Qing's home using electricity..."

When Bai Song said this, he suddenly woke up: "On behalf of the detachment, I suspect that Lin Qing did not die three days before we found the body! That electricity consumption came to confuse us! Lin Liang probably just turned off the air conditioner at the time. Waiting for the equipment!"

"What!" The generation detachment seemed to be electrocuted.

All current inferences are based on the determination of the time of death of the deceased.

All investigative directions were also deduced from the time three days before the discovery of the corpse.

This case is very special. The deceased was frozen. It is impossible to judge the time of death from the body itself. Therefore, the turning point of power consumption is currently the only basis for judgment by the police. If this basis is false, then all conclusions derived from the false basis are false.

The biggest contribution made by the generation detachment and others is also from the power consumption.

but...

If this was detained by criminals in advance, but the electrical appliances were turned off three days before the body was found... Then this...

The police were completely fooled.

...

"He went to turn off the power..." The generation detachment was still a little trembling: "Then, Lin Qing has been dead for many days. This is just to confuse...playing us..."

The generation detachment was autistic and felt a strong sense of frustration for a moment.

"Wait a moment," Liu Shuyuan said: "In such a short period of time, if Lin Liang entered Lin Qing's house and turned off the air conditioner and other equipment, how could he escape Ouyang Xinyu's investigation? There is a logical problem here, he After going there for less than five minutes, turning off the power is definitely enough, but I don’t believe it to remove the traces. If someone else removes the traces for him, then he doesn’t need to go, that person just turns off the power."

"It makes sense." The generation detachment heard it clearly over there. When he heard Liu Shuyuan's words, his mentality improved a lot. What Bai Song said was just a hypothesis, and there was no other theoretical basis to support it.

"I didn't have too much contact with Ouyang Xinyu," Sun Jie said: "But in our daily work here, except for East China, I also surveyed the site. If it really is as you said, then he enters the house again, this trace Even I can't hide."

"You forgot one thing," Bai Song thought for a while: "Just now, the phone call from Wang Huadong made it clear that Ouyang's hypothesis of the time of death proposed by her. Ouyang Xinyu said that the time of the deceased Lin Qing's struggling footprint It may have been half a month. In other words, ten days have passed when we found out that Lin Qing had died."

"This is not right," said the detachment: "Lin Qing's mother had a chat with Lin Qing five or six days before the death of the deceased."

"Did you make a phone call or made a voice?" Bai Song asked rhetorically.

"Um..." The detachment suddenly thought that she was a little stupid. Lin Qing's mother discovered Lin Qing's body because the murderer used Lin Qing's cell phone to send a message to her mother. That being the case, the "Lin Qing" who chatted with Lin Qing's mother before this may be all fake.

"None of these can explain the traces of turning off electrical appliances," Liu Shuyuan insisted.

"Who said?" Bai Song said: "Turn off the air conditioner and other equipment, it must be touched?"

"Pull the switch outside?" Liu Shuyuan immediately retorted, "The refrigerator at home has no electricity."

"The times have progressed," Bai Song pointed to the large screen in the monitoring room: "Electronic equipment has progressed faster. I just thought of one thing, that is, in Lin Qing's residence, many of the devices are smart devices, and there are smart speakers. Think. To turn off the air conditioner, you just need to open the door, say a few words at the door, and it will all be closed."

"Intelligent?" Liu Shuyuan and Sun Jie were lost in thought.

Everyone doesn't doubt that Lin Liang has the key to Lin Qing's residence. Lin Liang has lived here before, and it is not difficult to secretly match the key. If this is the case, people can do it without having to enter the door!

"That's not right, there is another problem here." The generation detachment took a deep breath. He has completely recovered: "Lin Qing's house was stolen twice, do you remember? After the first stolen, she changed The lock was stolen for the second time. She changed the lock again. And this lock has no traces of technical unlocking recently. Lin Liang, how come there is a new key?"

The clue that Lin Qing’s home was stolen twice, Bai Song almost forgot (Chapter 1150), but the generation team is still relatively solid. He not only knows that Lin Qing’s home has been stolen twice, but also that Lin Qing has changed twice. New locks are such details.

"On behalf of the detachment," Bai Song said: "What you said makes sense, but it explains the problem even more. Two thefts are not normal in themselves. This is one of them; the second is to report to the police twice, which definitely does not mean certain There are only two times, and I can only say that Lin Qing has only found it twice. If there is a third time, and the purpose is to steal the key in the house to match one, can Lin Qing find out that a thief has entered the house?

"What was the purpose of the two thefts before then?" The detachment was still puzzled.

"In this case, there are two suspects. One is likely to be Lin Liang, and the other is currently unknown. The first two thefts may be the matter of the other suspect." Bai Song said: "And then stolen again, then It may be that Lin Liang stole the key, or Lin Liang’s accomplices stole the key. After stealing it, he came out with one, and then went to open the door and return the key. Lin Qing changed the lock and got a few extra keys. No one will give it, most likely it will be kept at home."

"Wait a moment." Liu Shuyuan looked around, then went to the door and took a look outside: "Bai Song, you said that since Lin Qing's death time can fall forward, then Lin Qing's father doesn't have time to commit the crime. Is it possible that he did it?"

Hearing this, Bai Song was also taken aback. When he first asked Lin Qing's mother, he felt that Lin Qing's father might have a problem. However, he quickly regained consciousness: "If Lin Qing's father did it, how did Lin Liang die? We must know that our previous speculation was three days before the body was found, and Lin Liang died that day."

"That's right. If Lin Qing's father really was the murderer of Lin Qing, then he should also be the murderer of Lin Liang's case, and Lin Liang's case required a lot of arrangement, and he was definitely on the scene at the time. In addition, follow-ups are needed. To clean up the traces, these Lin Qing's fathers all have evidence of their absence." Liu Shuyuan said: "Then we should be able to try now to see if the electrical appliances in Lin Qing's home can be controlled by smart speakers and other devices."

"This is very simple", the deputy said: "There are our people near Lin Qing's residence. I immediately send someone to try it out. If it works, then immediately start investigating. I believe that the murderer did not let us so deliberately. Knowing the time of death of the deceased must be afraid of us going forward."

"Yes." Bai Song told the deputy detachment about some of Ouyang Xinyu's findings and conjectures: "I have never figured out why the murderer had to send a message to Lin Qing's mother after three days to come over. In fact, he was afraid of police investigation. We don’t know about the buckle made by the murderer if we don’t have a longer period of electricity usage records! We have to say that the murderer’s calculations are really amazing!"

"That's not right? How could this electricity usage record be only three days? Three months is possible, right?" Liu Shuyuan still raised objections.

"You know, the murderer doesn't necessarily know, and the murderer may also be afraid that the police may call too little," Sun Jie said.

"There is another reason," Bai Song said: "The murderer is also afraid of Lin Qing's cell phone in his hand. If it takes a long time, Lin Qing's mother takes the initiative to go to Lin Qing's house and then call the police. The murderer may be located by the police. So, three days is a good middle point. Is it reasonable to say that?"

"Reasonable," Liu Shuyuan expressed his approval.

"It's not easy to get you to recognize it." Bai Song discovered that he hadn't seen him for nearly a year, and Liu Shuyuan had also made a lot of progress. He was able to find loopholes in his logic frequently.

"That's what you said," Liu Shuyuan groaned twice before thinking about the case.

After continuing to communicate with Dai Detachment for a while, a clue came from the WeChat account of Dai Detachment, where the deceased Lin Qing lived, and the smart speaker could indeed control the air conditioning and other equipment in the home!

Such a setting can directly make a lot of sense.

Lin Liang was almost 100% the murderer who killed and divided Lin Qing, and after the killing, he froze in the refrigerator.

After Lin Qing died, the air conditioner and other equipment in her residence were still running 24 hours a day. After a few days, Lin Liang took the time to go there, turned off the electrical appliances, and forged Lin Qing's death time.

This setting can be said to be unheard of for Bai Song, and if some words hadn't rushed to that level, he wouldn't have thought it could be done like this.

There are a few points in this. The first is that Lin Liang’s time is not in the morning and evening rush hours. Yuzhou’s taxis are notoriously fast, and the total round trip distance has been shortened to about 40 minutes. The second is that Lin Liang is here. I have lived in this neighborhood and I am very familiar with the neighborhood. It is easy to hide from the camera. It only takes ten minutes to do such a thing.

Therefore, Lin Liang has never left everyone's sight for more than an hour on the side of Lin Liang's friend, friend and dog friend, which means that if it works, Lin Liang still has to create an alibi for himself.

"I'm not interested in Lin Liang right now," Bai Song said: "His IQ is definitely not going to come up with such a plan, and if he is smarter, he won't be killed. There must be someone behind this matter~ lightnovelpub.net~ and this talent is the real mastermind."

"Indeed, but if Lin Qing died for half a month, Lin Liang would not be very afraid at that time. It is normal to go to the bath center to take a bath." Sun Jie also nodded.

"Bai Chu, you people are really amazing. If this kind of thing makes us stupid think about it, we won't think of it. If we continue to study on that fake death time, then..." I really admire him, his thinking in this area is completely locked, and he can't think of it.

And just like smart audio devices, the generation detachment has never been in contact with them. This should be something that has only been launched in large numbers this year. There used to be, but there are even fewer.

"I also happened to happen," Bai Song said: "What I said is not necessarily correct, but our thinking should be opened up. However, you don't have to worry about the detachment. We still have several clues to investigate this case. I feel that I am a bull and think that I have no plan, but no matter how professional he is, he is afraid of us, not to mention that we have now solved a big mystery."

"I'm fine." The generation detachment is full of fighting spirit: "To be honest, when a policeman, this kind of case is what the police should do. Compared with this case, the previous cases are really nothing!"

The generation detachment is a little excited. He has experienced so many murders for so many years, and none of them have caused him such headaches and excitement. If this case can be solved, he will be able to retire!

At this moment, the mobile phone of the detachment rang, and Bai Song had to hang up first.

In less than five minutes, the generation detachment immediately called Bai Song over again: "The soil that buried Lin Liang at that time has been found in the construction dump. Bai Chuan, do you want an expert to see it."

"Okay, let me tell him, and we will go too." Bai Song said immediately.
