Police Detective

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

This monitoring room is quite strange. The large screen is a newly replaced 65-inch TV, but the image is very unclear. Obviously the camera hasn't been changed, just the monitor. There is a clear age difference in the graphics and displays.

"Besides this, are there any other major clues?" Bai Song was ready to listen to what the detachment had to say.

"Yes, and the most important thing is that there is a driver who has an impression of this person. Because he didn't say anything when the driver chatted with him, he directly showed the driver an address and asked him to drive there. The driver thought he was mute, so he had an impression." , said on behalf of the detachment: "The driver successfully identified Lin Liang."

"What about the distance between the two cars?" Bai Song asked, "How long did he stay at Lin Qing's place?"

"There is no specific video of where the car stopped, but it can be roughly inferred that it took 10 to 15 minutes from the time he got off the car to the time he took a taxi again." The deputy detachment said: "It feels like he went there alone to have something to do, and then left. Even if he walked quickly, he would not stay at Lin Qing's house for more than 5 minutes. "

"Then what was he doing?" Bai Song thought for a moment: "Did the driver who identified Lin Liang mention that Lin Liang had something in his hand?"

"He said no. In his impression, Lin Liang only brought his mobile phone," the detachment representative said, "but the payment was made in cash."

"Then why did he go here?" Bai Song felt confused.

"According to expert Ouyang's judgment, there were two people at the scene who committed the crime, which definitely could not be completed within 5 minutes. So he should not be the murderer, the murderer." The deputy detachment said: "We still suspect Li Ruibin and his son."

After speaking on behalf of the detachment, he found that Bai Song did not reply to him. Then he thought that Bai Song had not answered the question he asked. He wanted to say something, but he didn't know what to say.

"Did he just take a look and have no other intentions?" Liu Shuyuan said.

"Isn't that too much of a coincidence?" Sun Jie said: "This time is almost the same as the death time of the deceased. It stands to reason that if you go at this time, you will encounter a murderer."

"This timing is indeed a coincidence, what 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 the time when Lin Qing's house was using electricity."

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

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

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

All investigation directions are based on the time three days before the body was found.

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 the only basis for the police's judgment at present. If this basis is false, then all conclusions derived from the false basis are false.

The biggest contribution made by Dai detachment and others is also to find clues from the power consumption.

but

If this was done by criminals in advance and they just turned off the electrical appliances three days before the body was found, then this

The police were completely fooled.

"He went to turn off the power." The deputy detachment was still a little trembling: "So, Lin Qing has been dead for many days. This is just to confuse and play tricks on us."

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

"Wait a minute," Liu Shuyuan said: "In such a short period of time, if Lin Liang entered Lin Qing's home and turned off the air conditioner and other equipment, how could he escape Ouyang Xinyu's detection? There is a logical problem here. He It's been less than five minutes. Turning off the power is definitely enough, but I don't believe it. If someone else cleans up the traces for him, then he doesn't need to go. That person can just turn off the power."

"It makes sense." The acting detachment heard it clearly over there. He felt much better after hearing Liu Shuyuan's words. What Bai Song said was just a hypothesis and had no other theoretical basis to support it.

"I don't have much contact with Ouyang Xinyu," Sun Jie said, "but in our daily work here, apart from East China, I am also the one who investigates the scene. If it is true as you said, then he entered the house again, this trace Even I can’t escape.”

"You have forgotten one thing." Bai Song thought for a while: "The phone call from Wang Huadong just now made it very clear that Ouyang proposed the time of death hypothesis. Ouyang Xinyu said that the time when the deceased Lin Qing struggled and left footprints It may have been half a month. That means ten days have passed since we found out that Lin Qing was dead.”

"This is not right," said the detachment representative, "Lin Qing's mother chatted with Lin Qing five or six days before the deceased's death."

"Did you make a call or send a voice message?" Bai Song asked.

"Well" the detachment suddenly thought that it was a little stupid. Lin Qing's mother found Lin Qing's body because the murderer used Lin Qing's mobile phone to send messages to her mother. In this case, the "Lin Qing" who chatted with Lin Qing's mother before this may be fake.

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

"Who said," Bai Song said, "turning off air conditioning and other equipment must require touching?"

"Turn on the electric switch outside?" Liu Shuyuan immediately retorted: "Then the refrigerator at home is out of power."

"The times have progressed," Bai Song pointed to the big screen in the monitoring room: "Electronic equipment has advanced faster. One thing I just thought of is that in Lin Qing's residence, there are many smart devices and smart speakers. I think. To turn off things like air conditioning, just open the door, say a few words at the door, and it's all turned off."

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

No one doubted that Lin Liang had the key to Lin Qing's residence. Lin Liang had lived here before, so it was not difficult to secretly obtain the key. If this is the case, people really don’t need to enter the door to get it done!

"No, there is another problem here." The deputy detachment took a deep breath. He had completely recovered: "Lin Qing's house was robbed twice. Do you still remember? After the first robbery, she changed The lock was stolen the second time and she changed it again, and there was no trace of the lock being unlocked recently. Lin Liang, how come you have a new key?”

Bai Song had almost forgotten the clue that Lin Qing's home had been robbed twice (Chapter 1150), but the acting detachment was still relatively solid. He not only knew that Lin Qing's home had been robbed twice, but also knew that Lin Qing had changed her clothes both times. Such details as new locks.

"On behalf of the detachment," Bai Song said, "What you said makes sense, but it further illustrates the problem. Two thefts in itself are abnormal, and this is one; second, calling the police twice does not necessarily mean that There were only two times. It can only be said that Lin Qing only discovered it twice. If there was a third time, and the purpose was to enter the house to steal a key, would Lin Qing have discovered that there was a thief in the house? "

"Then what was the purpose of the two previous thefts?" The deputy detachment was still puzzled.

"There are two suspects in this case. One is most likely Lin Liang, and the other is unknown at the moment. The first two thefts may have been the fault of another suspect." Bai Song said: "And if it was stolen again later, then It was possible that Lin Liang stole the key, or that Lin Liang's accomplices stole the key, got one, and then went over to open the door and return the key. Lin Qing changed the lock and had the extra keys. No one gave it to me, most likely it was left at home.”

"Wait a minute." 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 be moved forward, then Lin Qing's father does not have no time to commit crimes. This Is it possible that he did it?"

Hearing this, Bai Song was also stunned. When he just asked Lin Qing's mother, he felt that there might be something wrong with Lin Qing's father. However, he quickly regained consciousness: "If it was Lin Qing's father who did it, then how did Lin Liang die? You must know that our previous speculation was three days before the body was found, and Lin Liang also died that day."

"That's right. If Lin Qing's father is really the murderer of Lin Qing, then he should also be the murderer of Lin Liang's case. Lin Liang's case requires a lot of arrangements. He must have been at the scene at the time. In addition, follow-up is needed. Go and clean up the traces. Lin Qing’s father has alibi,” Liu Shuyuan said, “Then we should try it now to see if the appliances in Lin Qing’s home can be controlled through smart speakers and other devices.”

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

"Yes." Bai Song told the acting detachment some of Ouyang Xinyu's findings and conjectures: "I have never figured out why the murderer sent a message to Lin Qing's mother after three days to ask her to come over. In fact, he was afraid that the police would investigate. Without the electricity usage record for a longer period of time, we might not know what the murderer did! I have to say that this murderer is really good at calculations!”

"That's not right, right? How can this electricity consumption record only last for three days? It's possible for three months, right?" Liu Shuyuan still raised an objection.

"You know, the murderer may not know, and the murderer may also be afraid that the police will call too few," Sun Jie said.

"There is another reason," Bai Song said: "The murderer had Lin Qing's cell phone in his hand, and he himself was afraid. If it takes a long time, Lin Qing's mother takes the initiative to go to Lin Qing's house and then calls the police. Then The murderer may be located by the police or something, so three days is a good halfway point, is that reasonable?”

"Reasonable", Liu Shuyuan expressed his approval.

"It's not easy to get your approval." Bai Song found that Liu Shuyuan had improved a lot after not seeing him for nearly a year, and he could often find loopholes in his logic.

"That's what you said." Liu Shuyuan snorted twice and began to think about the case.

After continuing to communicate with the detachment on behalf of the detachment for a while, clues came from the WeChat account of the detachment on behalf of the deceased. In the residence of the deceased Lin Qing, the smart speaker can indeed control the air conditioner and other equipment in the home!

This kind of setting can directly explain many things.

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

After Lin Qing's death, the air conditioner and other equipment in her residence were still running 24 hours a day. A few days later, Lin Liang took the time to go there and turn off the electrical appliances, thus forging the time of Lin Qing's death.

This setting can be said to be unheard of by Bai Song. If some words hadn't reached that level, he wouldn't have imagined that he could do this.

There are several points here. The first is that the time when Lin Liang went was not during the morning and evening rush hours, and taxis in Yuzhou City are notoriously fast. The total round-trip journey was shortened to about 40 minutes; the second was that Lin Liang was in I have lived here and am very familiar with the area. It is easy to hide from the camera. It only takes ten minutes to do such a thing.

Therefore, among Lin Liang's friends, Lin Liang never left everyone's sight for more than an hour, which meant that Lin Liang still had to create an alibi for himself.

"I'm not interested in Lin Liang now," Bai Song said: "His IQ is such that he would never come up with such a plan, and if he was smarter, he wouldn't be killed. There must be someone behind this matter, And this person is the real mastermind.”

"Indeed, but if Lin Qing has been dead for half a month, Lin Liang will not be so afraid at that time, and it is normal to go to the bathing center to take a bath." Sun Jie also nodded.

"Bai Chu, you people are really powerful. If we stupid people were to think about this kind of thing, we would never think of it. If we continue to study the fake death time, then" the deputy detachment is really impressed , His thinking in this regard is completely locked, and he can't think of anything he can't think of.

And for devices like smart speakers, the generation detachment has never been exposed to them. This should only start to be launched in large quantities this year. There were before, but less so.

"It just happened to me," Bai Song said, "What I said may not be correct, but our thinking should be open now. However, you don't have to worry, acting detachment, we still have several clues to investigate this case. The murderer himself He thinks he is awesome and thinks he has all the answers, but no matter how professional he is, he is still afraid of us, not to mention that we have solved a big mystery now.”

"I don't have a problem with that," the acting detachment was full of fighting spirit: "To be honest, as a police officer, handling this kind of case is what the police should do. Compared with this case, the previous cases are really nothing!"

The acting detachment was a little excited. He had experienced so many murder cases over the years, and none of them had made him so headache and excited. If this case could be solved, he could be proud of it until he retired!

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

In less than five minutes, the acting detachment immediately called Bai Song again: "The soil where Lin Liang was buried at that time has been found in the construction garbage dump. Bai Chu, would you like an expert to take a look?"

"Okay, I'll tell him, and we'll go too," Bai Song said immediately.
