For the next time, Hu Shanquan said nothing, as if he was deaf. No matter what he was asked, he closed his eyes and seemed to refuse to speak.
At this point, the interrogation had to be temporarily terminated.
In another interrogation room, Shen Yu's behavior was almost exactly the same as Hu Shanquan's. She also said nothing. If she got tired of being asked, she would keep repeating a sentence.
"Evidence, need evidence."
Shen Yu knew very well that he could not escape the responsibility of instigating Hu Daodao to invade the national public information platform.
Therefore, she simply said nothing. Anyway, the weight of confession is not high. As long as the evidence chain is complete, the police can still convict her.
But that's all.
As for the two cases related to Xiao Huajun, they have nothing to do with her, at least that's what she thinks.
In those two cases, the first case in which Xiao Huajun's father fell from a building, she was not involved. She only helped Xiao Huajun cover up some things afterwards.
Although she was involved in the second 'Ma Yu case', after many inquiries, Xiao Huajun's current mental state is very bad.
Therefore, Xiao Huajun's testimony is not enough to convict her.
At eight o'clock in the evening, the office of the Crime Squad was still brightly lit.
"Team Leng, look at this."
Li Jie found an envelope containing photos from Shen Yu's belongings. When he saw the envelope, he immediately remembered where it came from.
The two dark red marks on the back of the envelope are enough to prove that Shen Yu got this envelope from the Hongguang Photography Studio.
Li Jie didn't expect that Shen Yu would keep this envelope.
Leng Xiaobing took the evidence bag with his gloves on and looked at the envelope carefully under the LED light. The words "Red Light Photo Studio" were printed on the front of the envelope.
After a moment, he said in an uncertain tone.
"Is this blood?"
Leng Xiaobing has been a police officer for more than ten years and has been active on the front line. He has seen many kinds of evidence. The dark red mark on the envelope looks like old blood stains.
"Chen Han, go and call Lao Gu."
Immediately, Leng Xiaobing asked Chen Han to invite forensic doctor Gu over. He had to ask Lao Gu if he could extract the DNA from it.
Generally speaking, DNA can still be extracted from blood stains even if they are more than ten or even twenty years old.
But the mark on the envelope was very faint, so he wasn't sure.
After a while, forensic doctor Gu hurried over in a white coat.
"Xiao Bing, what do you want from me?"
Leng Xiaobing directly handed over the evidence bag: "Lao Gu, look at this. I think it's blood. In this case, can DNA be extracted from it?"
Forensic Doctor Gu took the evidence bag, looked at it for a moment, and then gave his own conclusion.
"It does look like blood stains, and they are very old. According to preliminary judgment, they are at least ten years old."
Leng Xiaobing said bluntly: "Can it be extracted?"
After pondering for a moment, Forensic Doctor Gu frowned and replied.
"I'll try, it might be a little difficult."
"How long will it take to get the results?"
Normally, the entire process of detecting a set of DNA takes six hours, but this does not include the time of extraction.
Forensic Doctor Gu estimated the time and then replied.
"It will be tomorrow afternoon at the earliest."
…
…
…
In a blink of an eye, it was the afternoon of the next day, and most of the day had passed. The interrogation was not progressing smoothly. Both Hu Shanquan and Shen Yu were very resistant.
Fortunately for Shen Yu, with Hu Daodao's testimony and the testimony extracted from the mobile phone, it is basically not a problem to convict Shen Yu.
But it’s more difficult over Hu Shanquan.
The Haizhou case is an old case. The earliest case was more than 20 years ago. It has been so long that it is difficult to find direct evidence.
Just when Leng Xiaobing was frowning, forensic doctor Gu walked into the office of the serious crime team with the fresh test results.
It's just that his face looks a little weird.
"Lao Gu, has the report been released?"
Leng Xiaobing saw Forensic Doctor Gu walking towards him with a document and hurriedly greeted him.
"Yes."
Forensic Doctor Gu nodded: "The results are out, the extraction process went very smoothly, and the testing process went very smoothly as well."
"It's just that the blood stains on it are not from one person, but from two people."
"Two people?"
Leng Xiaobing took the report with a surprised look on his face and quickly read it.
Huh?
While flipping through the pages, Leng Xiaobing couldn't help but let out a sigh.
The DNA sequencing of the two blood stains on the envelope were completely inconsistent and clearly belonged to two people, one of whom was an unknown male.
Another blood stain matched Hu Shanquan's DNA.
After reading the test results, Leng Xiaobing frowned subconsciously.
Why is there Hu Shanquan’s blood stain on the envelope?
Moreover, the other blood stain belonged to an unknown man. Could it be that Hu Shanquan committed a crime in the photo studio?
But all the people he killed were women, and there were no male victims.
Whose is the other DNA?
At this moment, Forensic Doctor Gu's cell phone rang. When he lowered his head, he saw that it was a message from the identification center.
As soon as he saw this piece of authority, Forensic Doctor Gu immediately repeated the news to Leng Xiaobing.
"By the way, Xiaobing, the DNA comparison results about Shen Yu and Hu Shanquan are also out."
Leng Xiaobing came back from his thoughts after hearing this: "What is the result?"
Forensic Doctor Gu shook his head: "There is no parent-child relationship between the two."
No parent-child relationship?
In other words, Hu Shanquan's statement that Shen Yu is his daughter is all imaginary?
This result confirmed another guess in Leng Xiaobing's mind.
Hu Shanquan's illness did not heal, and he remained a mental patient from beginning to end.
"okay, I get it."
Leng Xiaobing nodded: "Lao Gu, you have worked hard these past two days. When you are done, I will treat you to dinner."
After saying that, Leng Xiaobing hurriedly left the office with the envelope.
He was going to the interrogation room to ask Shen Yu and when she got the envelope from Hongguang Photography Studio.
Perhaps, this envelope will bring him some unexpected gains.
However, many times, things develop differently than expected.
When Shen Yu saw the envelope, there was indeed an abnormal fluctuation in his eyes. Leng Xiaobing keenly captured this flashing abnormality.
But that’s it.
When Leng Xiaobing asked again, Shen Yu still remained silent.
Seeing Shen Yu's expression of indifference, Leng Xiaobing couldn't help but feel anxious in his heart.
If the stalemate continues like this, Hu Shanquan will be able to leave in forty-eight hours at most.
Thinking of this, Leng Xiaobing decided to take risks and staged a scene to arouse the enemy.
"Shen Yu, do you know Hu Shanquan?"
‘Hu Shanquan?’
When Shen Yu heard this name, she felt a little familiar, as if she had heard it somewhere, but she couldn't remember it.
