Wang Qin was stunned for a moment, and hurriedly took out the phone and dialed Xiao Shang, who said that there were a few ribs and no bone sticks.

Wang Qin hung up the phone and breathed a sigh of relief, and Zhou Wang also breathed a sigh of relief and said: "He shouldn't dare, the difference between human bones and pig bones is still very big, a little more careful will find that if he dares to sell, once he is discovered, it will be troublesome." ”

At this time, Xiao Cai, who was in the slaughterhouse, stood at the door and said to Zhou Wang: "Old Zhou, I found blood stains in the cracks, but the minced meat was not found, but there were some bone residues." ”

"Bone scum?" Zhou Wang turned his head to look at Wang Qin and said: "His knife skills are so good, and he has professional knives, although I only saw one jar, I can also tell that it is deboned and removed meat, why is there so much bone residue?" ”

Wang Qin blinked, as if he remembered something, turned his head and ran out of the courtyard.

Xiao Cai asked again: "This room is basically like this, there are a lot of samples, we will bring it back for testing first, and the report will be given to you as soon as it comes out." ”

Zhou Wang said: "Hard work! ”

Xiao Cai asked again: "You don't need to look at other houses, right?" If it's a big project like this one, then let's talk about it tomorrow, and the inspection materials will have to be sent back to the team as soon as possible......"

Zhou Wang didn't hear the latter words, he stood in the courtyard and stared at the main house in a daze, until Wang Qin came back and patted him, and said excitedly: "When I went out before, the villagers said that there was a pig in the village, the old two, usually the brothers collected pigs from his house, and his family asked the brothers to help buy pig feed, and the old couple had no car, so that a lot of things were saved, and the pigs sold to the brothers were slightly cheaper, and both families were suitable!" ”

"Pig feed?"

"Yes, pigs eat everything, and those who raise one or two don't need to deliberately buy pig feed......"

"I forgot, there's bone meal in pig feed!"

"Yes!" Wang Qin's eyes lit up: "I just asked the old couple, and they said that Chen Qingsong had just sent them a few bags of pig feed the day before yesterday!" They also complained that there was a lot of bone residue this time......"

"What the hell is he broken? I'll check it out first! Zhou Wang walked to the gate of the courtyard and suddenly turned around and said, "Think about what is in this main room?" ”

"What do you mean?"

"He's cleaned up!"

……

Chen Qingsong would never have thought that the evidence that he thought the police could not find in a short period of time would be defeated by his sudden diligence.

At dusk, Zhou Wang sifted out a lot of bone residue in the pig feed.

Wang Qin and the police searched the house over and over again very carefully, and almost picked up the kang, the house is full of old furniture, kang cabinets, standing cabinets, wine cabinets, bookcases, not to mention anything else, there are so many drawers!

They searched for the suitcase on the top of the cabinet and the gap at the bottom of the furniture, but they didn't find anything, but Wang Qin knew that Zhou Wang was right, Chen Qingsong wouldn't clean up the house for no reason, if it was just hiding something, was it necessary to clean up the house?

There must be a reason.

Wang Qin stood in the middle of the room and looked at it again.

Bookcase!

Wang Qin finally saw that something was wrong!

One side of the wall behind the bookcase reveals a slightly darker color, and the high mark on the side of the bookcase, to be honest, if you don't look carefully, you really can't see it, the original wall has not been refreshed for many years, and the white wall is about to become a black wall, and this slightly deeper imprint may indicate that this bookcase has been passive!

The police searched here, and there were a few books on raising pigs and killing pigs on the upper floor of the glass door, and the complete works of Sherlock Holmes, Conan, the code of the detective and other books were neatly placed on the lower floors, and the police didn't care about it after looking at it.

Wang Qin hurriedly worked with the police to lift the bookcase out together, and turned his head to see that there was a baffle on the wall, and there was actually a mezzanine on the wall!

"What the hell is that I've watched too many movies!" Wang Qin shouted in surprise.

Removing the baffle on the interlayer, Wang Qin couldn't wait to take a look, inside were two sealed brown jars, faintly smelling of wine, he had a premonition of what was inside, and took a deep breath.

Wang Qin and the police took out the jar together, and then looked inside, it was a pothole.

"Dig deeper, and this wall will be cut through!" Wang Qin muttered.

A policeman said: "Why else would he clean up the house, remove the bookcase, and dig out such a big hole, don't clean it well, we can see it when we come." ”

Wang Qin nodded.

Then several people studied how to open the jar, which was sealed as if it was not going to be opened again, and the groove of the jar was sealed with wax.

Wang Qin decided to bring it back to the team and find someone from the technical department to open it.

The cans were loaded into the car, Xiao Shang's phone also called, and the nearby auto repair shops did not find Chen Qingsong's van.

Wang Qin said: "Let's go back to the team and talk about it first." ”

……

The bone residue and the two jars were sent to the technical department, and Dalong and Lao Niu were still doing the comparison of the six jars.

Zhou Wang followed Wang Qin back to their office, and Xiao Shang and Liu Bing had just returned.

"If nothing else, the bodies of the two victims should have been found." Wang Qin said when he entered the house.

Xiao Shang hurriedly asked how he found it, Wang Qin's eyebrows danced and described, and Xiao Shang and Liu Bing's mouths didn't close.

After Wang Qin finished speaking, the office was quiet for a while, drinking water and smoking.

Liu Bing suddenly asked: "What I can't find now is Chen Zixuan and the van, and there is another doubt, why did Chen Qingsong throw the corpse?" ”

"Yes!" Wang Qin pulled the clipboard, wiped it clean, and began to rewrite: "Cheng Qingsong should have moved his hand on Tuesday, after Chen Zixuan went to school, before the store opened, that is, between seven and nine o'clock, because the murder process was in the living room, and there was blood, so the sofa was replaced......"

"Wounds!" Zhou Wang suddenly shouted.

Wang Qin and the three looked at him at the same time.

"There are no wounds on the body parts of the abdomen!" There was light in Zhou Wang's eyes: "If there was a sudden quarrel, and it was with a knife, why did he have a knife in his hand?" If you use a knife, you should be stabbing in the abdomen, and you can't stab you in the heart because of a slap, right? ”

"What's inside, Lao Zhou, don't get excited first, let's push the cause of death later, now let's make the timeline clear."

As soon as Wang Qin's voice fell, the mobile phone rang, and Wang Qin couldn't hide his excitement after connecting: "Found it?" ”

Zhou Wang's face was almost on Wang Qin's face, Wang Qin hung up the phone and pushed Zhou Wang away: "Can't wait for these two minutes?" ”

"Found the couch?" Zhou Wang asked excitedly.

Wang Qin sighed before he said:

"The police on Luoxia Street are really powerful, and they followed the collection of waste in the afternoon, but fortunately they were not sent to the garbage station, and they were bought for thirty yuan halfway, but the sofa was found outside the community on Wednesday morning when the waste was collected, and it was sold in the afternoon of the same day, and the buyer bought it back and cleaned it, and it could be delivered in a while."

"I'll sympathize with my colleagues in the technical department for a few seconds!" Xiao Shang said.

"Not a big problem! Blood stains on the fibrous tissue are difficult to remove with household cleaners and can seep into the sofa...... Wait a minute, when did you pick up the garbage and pick up the sofa? Zhou Wang asked hurriedly.

"Wednesday!" Wang Qin frowned: "Why is it Wednesday?" ”
