The assistant nodded.

Together with the other policemen, she packed the body and carried it away.

When she passed by Chu Feng, she glanced at Chu Feng distressedly.

There was no monitoring at the construction site, and there was no way to tell how Sun Qionghua and Chu Yucheng got in, and there were only a few bricks next to the cement pillars, and only one had blood stains on them.

It must have been bloody, accidentally stained.

Jiang Qingrui's eyes flickered, and she took out the luminol reagent, which is specially used to detect blood stains, as long as there is a little blood stain, no matter how many times it is diluted, it can be detected.

Soon, there was a blue reaction on the ground.

Xu Shu slowly spoke: "These are all bloodstains?" ”

The blood spilled all the way to the side of the cement pillar.

It seems that the murderer killed Sun Qionghua's mother and son here, and then destroyed the body on the spot.

He may have felt that as long as the body was hidden in a cement pillar, no one would ever find it.

But he miscalculated.

However, Sun Qionghua's mother and son, what enemies can they have?

Moreover, I hate it so much that I don't even let go of children.

Xu Shu collects evidence at the scene.

Most of the places were lime and stones, which made it more difficult to collect fingerprints, and after searching for more than an hour, he decided to take all the workers back to the police station for interrogation.

The workers were quite reluctant at first, but Xu Shu also said that he just asked about the specific situation, and if he hadn't done it, he would be able to leave soon.

As soon as everyone summed up, they didn't do anything wrong, and they weren't afraid of ghosts knocking on the door in the middle of the night, so they went to the police station.

Xu Ying and Jiang Wu were interrogated together.

Jiang Wu was originally investigating the situation of Sun Gui's family, and after learning the news of the death, he hurried back to the police station.

The two were still betting when they entered the interrogation room.

Xu Ying said: "I don't think they are murderers, they obviously have nothing to do with this mother and son." ”

After the murder occurred, Xu Shu had already told them about the case through his mobile phone.

Jiang Wu didn't think so.

"Dare to kill people at the construction site, it may also be because he can handle corpses well, after all, this place is familiar to him."

The two people said that the public was reasonable, and the mother-in-law said that the mother-in-law was reasonable.

Before he could go in for interrogation, he almost got into a fight outside.

Or Xu Shu coughed lightly: "Are you two too idle?" ”

Xu Ying snorted lightly and took the lead in entering the interrogation room, followed by Jiang Wu.

There were twenty-three workers in total.

More than a dozen police officers were in charge of the interrogation, and after more than two hours, it was concluded that none of them had a motive for the crime.

They are all familiar with Sun Qionghua's mother and son, after all, most of the shopping is in her family's small supermarket, mixed around, they are all familiar, and Sun Qionghua is very good, sometimes when the weather is hot, they will cook some mung bean soup for them, and send it over after being chilled, they are also willing to consume in her supermarket, which is a virtuous circle.

Really, there is no motive for the crime.

In the end, he let them all go.

Moreover, they did not provide any effective clues, but they knew that Sun Qionghua had been missing for a long time, and occasionally went to the small supermarket to inquire about the situation, but they all ended up in vain.

Jiang Wu glanced at Xu Ying proudly: "Look, what I said before is right." ”

"I can tell you, the relationship between Sun Qionghua and Sun Gui is really bad, and she has rarely come back since she left home in high school."

Xu Ying wrung her eyebrows, "Rarely come back?" Then after she went to the hospital this time...... How can you sign a donation agreement? I think this Sun Gui must know something. ”

Xu Shu walked out of the office at this time and glanced at them: "What are you two doing in a daze?" Come to the meeting. ”

"Yes, master."

In the forensic office, after getting the autopsy consent signed by Chu Feng, Jiang Qingrui began to dissect.

First of all, all the cement on the surface of the corpse should be removed.

It had already taken more than an hour to remove them, because they had to be careful to minimize the damage to the corpse.

The back of Sun Qionghua's head was sunken, obviously he was hit with a lot of stones, but there were no stones at the scene, because they were sealed with cement, so the corpse was not decomposed, and many wounds could still be seen.

The assistant is dissecting Chu Yucheng's body.

She exclaimed: "Forensic Doctor Jiang, this deceased's hands and feet were broken alive. ”

Knock it off hard, how painful it is.

The assistant couldn't imagine the pain.

Jiang Qingrui's face was ugly.

In the beginning, she had all felt it all by sharing.

Pain, despair with no way to turn for help.

Finally, it is sealed directly in cement.

If it weren't for Chu Feng's insistence and Jiang Wu's unremitting investigation, I am afraid that in this life, there would never be a bright day.

"Sun Qionghua has traces of being tied up in her hands, she may have been imprisoned before she died, what about Chu Yucheng?"

The assistant also found out.

She said in a deep voice: "There are marks, and there are tooth marks, which look like the deceased bit himself." ”

"What did they go through before they died?"

Jiang Qingrui could only judge that the deceased had died ten days ago, while Chu Feng said that they had been missing for half a month, and it had been exactly fifteen days since the day Sun Qionghua and the two left the hospital.

For five days in between, the mother and son were imprisoned.

But who will be the one who will imprison them?

Jiang Qingrui didn't find any traces of drugs in their bodies, and their stomachs were empty.

She furrowed her eyebrows, a hint of solemnity crossed her eyes.

This......

She recovered the body, left the autopsy room, and began writing the autopsy report.

On the surface of the corpse, the friction injuries on the wrists and ankles, followed by the impact wounds on the top of Sun Qionghua's head, this is a real fatal injury, and Chu Yucheng has a lot more injuries on his body, the murderer seems to be trying to vent his anger, he is extremely ruthless, there are whipping wounds on his body, and the flesh and blood on his back are blurred.

He was still breathing when he was finally put into the cement.

The real cause of death is asphyxiation.

Finally, when the autopsy report was handed to Xu Shu, after reading it, he also had doubts in his eyes.

He spoke slowly: "Looking at the autopsy report, I can only conclude that Sun Qionghua has enemies, and to a large extent, he is a man. ”

Xu Shu suddenly remembered someone.

He glanced at Jiang Qingrui and said, "Let's go find out about Sun Qionghua's social relations, I learned from Chu Feng's words before that Sun Qionghua's mother introduced her to a man." ”

Jiang Qingrui hesitated: "Then let's act separately?" ”

"Well, you go to Sun Qionghua's mother."

"Okay."

Jiang Qingrui called Qiao Linlin away.

She felt that with Qiao Linlin's temper, she might be able to restrain Sun Qionghua's mother.

The grandmother was still in the hospital, and when she saw Jiang Qingrui, a trace of impatience crossed her eyes.
