Chapter 136 The One Who Disappeared?

Cen Lian and Tang Hua walked into the room where Wu Qiushan was.

This should have been Cheng Xiaoyan's room. Some traces of her past life were buried in various sundries. If you didn't look carefully, it would be difficult to notice.

"It can be seen that Cheng Yong doesn't care about his daughter as much as he imagined. This room has become a sundries room," Tang Hua looked at the messy room, "So what did you find?"

"Traces of high heels," Wu Qiushan's position was a bit tricky, just touching the window of the room.

Most of the other places in the middle and on the ground were piled with messy sundries, some of which were even covered with a finger-thick dust.

And next to where he was standing, there was a slightly blurred footprint.

"There are footprints, maybe fingerprints," Cen Lian squatted down to take a look, "This is obviously a female footprint, and it was left recently."

"Found it," Wu Qiushan stood in this position to try to find possible fingerprints, "The fingerprints are relatively complete and clear. If this person's fingerprints exist in the fingerprint database, I am 90% sure that I can match them."

Cen Lian praised Wu Qiushan's technology.

So Tang Hua helped Wu Qiushan to extract all the fingerprints and footprints.

Cen Lian looked up at the window that was close at hand.

According to the records at the time, Cheng Xiaoyan jumped from this window.

She jumped from the sixth floor of this old residential building and ended her young life.

No one knows what she experienced before her death.

"We overlooked a possibility," Cen Lian suddenly said when Wu Qiushan put the extracted fingerprints and footprints back into the investigation box, "Who said the murderer can't be a woman? If she hired a killer or there were other accomplices, then she didn't have to do the dismemberment herself."

"But Brother Yue said that this kind of knife mark was cut with great hatred and required considerable strength." Tang Hua was puzzled.

"What if two people took the knife at the same time?" Cen Lian had such a guess after seeing the female footprints.

Because he had already focused his suspicion on a person they had ignored before.

Cheng Xiaoyan's mother.

Wu Qiushan closed the investigation box and glanced at Cen Lian.

"You are suspecting Cheng Xiaoyan's mother." He asked in a positive tone, "This is also the object I am more suspicious of at the moment. Let's go back and compare the fingerprints first."

It takes very little time to compare fingerprints with a purpose.

After Wu Qiushan returned to the office, he turned on the computer and found the fingerprints of Cheng Xiaoyan's mother Qi Hongmei.

When he started to compare, Cen Lian had already determined that this was the correct answer from the text bubble that popped up in Qi Hongmei's photo.

It seems that this case is not so outrageous as to exceed common sense.

A father who commits domestic violence will not avenge his children, but a mother who disappeared a long time ago should not fade out of their sight.

Even if she divorced Cheng Yong when Cheng Xiaoyan was less than five years old, the reason was domestic violence.

"The fingerprints can be identified as the same," Wu Qiushan squinted his eyes and looked at the two fingerprints carefully. After there was absolutely no problem, he submitted them, "Qi Hongmei has been to Cheng Yong's house recently."

"Go ask Cheng Yong if he knows about this," Cen Lian was not sure why Qi Hongmei came, "We can't rule out the suspicion of husband and wife committing the crime."

Although Cen Lian said this, he actually ruled out the possibility that Cheng Yong was related to this case.

From the fact that he turned the room where Cheng Xiaoyan used to live into a utility room and never cleaned it, it can be seen that he did not have too deep feelings for his dead daughter.

Cheng Yong had been in the interrogation room since he was summoned. When Cen Lian went over, the police from Qinzhou City Bureau had already finished questioning him.

"This is the interrogation record," the criminal police officer in charge of the interrogation had a bad expression. When he saw Cen Lian and the others coming, he handed them the interrogation record with a forced smile, "In my experience, Cheng Yong has little to do with this case."

The criminal police officer in charge of the interrogation was already quite old and had a lot of interrogation experience. Cen Lian simply flipped through the interrogation record and guessed that this guy should be from the pre-trial.

Those who do pre-trial have a very keen sense of smell for criminals. Cheng Yong was ruled out of suspicion by him, which means that he really didn't get anything useful.

"We found a female fingerprint from his home. After comparison, it was confirmed that it was Cheng Xiaoyan's mother Qi Hongmei," Cen Lian immediately synchronized their latest findings to the criminal police, "Let's go in and ask about Qi Hongmei now."

After watching them walk into the interrogation room, the criminal police called Wei Guohua's mobile phone.

As for Qi Hongmei, they did ignore her before.

Cheng Yong was already sitting in the interrogation room very impatiently.

"Why are you here again!" He saw another policeman walk into the interrogation room, and he was waiting for them very impatiently, "I have already said that this matter has nothing to do with me, what else do you want to ask me!"

Cen Lian sat down calmly, "This time we are going to ask about your ex-wife Qi Hongmei."

Cheng Yong was stunned for a moment, as if he didn't expect to hear this name from Cen Lian.

"I have been divorced from her for almost 20 years. What's the point of you asking me about her?" Cheng Yong's expression was a little gloomy, and it was obvious that he didn't want to mention this person.

Cen Lian looked at Cheng Yong, whose face was not good, and was basically sure that he had not seen Qi Hongmei.

"Have you seen her recently?" Wu Qiushan asked.

"She can still come to see me?" Cheng Yong's expression was a little sarcastic, "It was this woman who caused me to be imprisoned for two years. How dare she show up in front of me?!"

Cen Lian remembered that this guy was imprisoned for domestic violence, and looking at his expression, he felt that there was no need to talk any more.

"Tell me what you did last week." Cen Lian did not expect him to say anything useful, so he simply planned to determine when Qi Hongmei came to his house based on the time he was not at home.

Cheng Yong reluctantly explained his general life trajectory half a month ago.

In fact, he was also afraid that this case would really have something to do with him. After all, it was a big case of murder and dismemberment. He had been in prison before and knew that it would be very troublesome if he was involved in such a case.

"Okay, wait a little longer and someone will take you away." Cen Lian was too lazy to look at him any more. After confirming the time, he went out with Wu Qiushan.

Tang Hua was standing at the door. When he saw them coming out, he quickly raised his phone and said, "Look in the group chat. There's a new clue!"
