Tang Shouren thought with a painful expression on his face. Even though he had really wanted his mother to die, now that he knew that his mother had been killed, he felt extremely unwilling to do so.
Zhou Zhimo picked up a photo and showed it to Tang Shouren: "Do you recognize this?"
Tang Shouren looked at the button in the photo: "This is a button."
He thought: "I seem to have seen it somewhere."
Zhou Zhimo asked him: "Think clearly, is this a button on your clothes?"
Tang Shouren shook his head and denied: "No. This style is very fashionable. I never use such dazzling things."
Zhou Zhimo sighed softly: "Then let's wait for the test results."
Soon, the test results came out.
In the office, Liang Yinuo told Zhou Zhimo: "Master, there are two fingerprints on that button."
Zhou Zhimo asked him: "Whose do they belong to?"
Liang Yinuo told him: "One fingerprint belongs to the deceased Liu Yuqin."
"The other fingerprint belongs to someone I don't know yet, but Curry didn't compare it."
Zhou Zhimo asked him: "Do you compare it with Tang Shouren's?"
Liang Yinuo said: "We have compared it and ruled out that it is Tang Shouren's fingerprint."
Zhou Zhimo looked up at him: "Isn't it his?"
Liang Yinuo nodded: "Yes, it's not his."
Zhou Zhimo analyzed: "The button fell in the corner of the sofa. When I picked it up, I touched the ground and there was dust."
"But the button is very clean, which means it was newly dropped."
"I have seen Liu Yuqin's clothes. There are no such buttons, and there are no missing buttons."
"It turned out that the fingerprints were hers and someone else's."
Zhou Zhimo looked at Liang Yinuo and said seriously: "The other fingerprint may be the murderer."
He ordered: "Everyone, touch it and see if there is anything missing from the information at hand."
Liang Yinuo nodded: "Okay, I'll call everyone to the conference room now."
In the conference room, Zhou Zhimo presented the complete information on the big screen for everyone to see if there was anything missing.
It was also suggested that the button found at the scene of the crime had the fingerprints of the deceased and another person.
Zhou Zhimo asked: "Think about it, are there any missing clues at the scene?"
Everyone looked through the information in their hands, checked their footprints and fingerprints, and found no other clues.
The small town was very peaceful. There had been two death cases like this in a short period of time. Everyone was very alert and carefully inspected the scene.
Just when everyone was at a loss what to do, Xiao Qi came in with a mobile hard drive and a few photos.
He explained: "I just checked something, I came here late."
Zhou Zhimo nodded: "It doesn't matter. Tell me, what clues have you found?"
Xiao Qi projected the information in the hard drive onto the big screen and pointed to the photos above: "Liu Yuqin's yard is next to the house on the east side."
"From another road, you can enter the yard next door."
"This yard has been uninhabited recently."
"I just checked the surveillance on that road."
"You see, on the day of the incident, Wang Xuechan, the daughter-in-law of the deceased, appeared on this road."
"Enter at this entrance and disappear."
"When Wang Xuechan appeared in the video again, it was already forty minutes later. She was obviously dodging."
"And this time period happened to be after Tang Shouren left the yard and before the thief entered the yard."
"We went to check the courtyard wall of Liu Yuqin's house again. Unfortunately, the weather has been dry recently and there were no traces left at all."
Liang Yinuo suddenly realized: "Wang Xuechan sneaked back and killed the old lady?"
He was worried again: "But why did Wang Xuechan kill the old lady?"
Xiao Qi shook his head: "This clue has just been discovered. We haven't found out more about Wang Xuechan, and we don't know her motives."
Zhou Zhimo ordered: "Go and check the clothes Wang Xuechan wore that day to see if the button is from her clothes."
"Another group will visit and investigate to see how the relationship between Wang Xueqin and Liu Yuqin is between mother-in-law and daughter-in-law."
"Don't alarm her first. Find a way to extract her fingerprints and compare them with the fingerprints on the button."
After the meeting, Zhou Zhimo went to see Tang Shouren in person: "You go back first."
Tang Shouren asked him: "Have you found anything now?"
Zhou Zhimo looked at him: when he came in, he had a gentle face pretending to be calm; after learning that his mother was a homicide, his expression obviously changed a lot.
This means that Tang Shouren was very sure that his mother committed suicide at first, and it was expected.
However, he did not expect that his mother did not commit suicide, but was killed.
Thinking of this, Zhou Zhimo touched the tip of his nose, looked up at Tang Shouren and asked him: "Director Tang, why do you insist that your mother committed suicide?"
"What are you hiding?"
Tang Shouren looked around, holding his hands on the armrests and saying nothing.
Zhou Zhimo crossed his arms in front of his chest and leaned on the table: "Now that we know that your mother was killed, you also want to know who the real murderer is, right?"
"It is your obligation to cooperate with our investigation and solve the case as soon as possible. It is also your last filial piety as a son."
Tang Shouren raised his hand and touched his ears, and spoke slowly: "When I came back from a business trip, I learned that my mother had moved to the old yard."
"After I finished my work, I went to the yard to see her."
"The old man and the young man knocked on the door and begged my mother for help."
"It was then that I learned that my mother actually had an abandoned illegitimate daughter, and she came to her door."
"The next afternoon, I want to discuss it with my mother and ask her what she thinks."
"But when I went there, I saw that young man leaving the yard with an old woman."
"The young man also cursed: We are barefoot and are not afraid of those who wear shoes. I am afraid of what they will do."
"At that moment, I was angry and scared."
"Sure enough, poor people come from poor places. What my mother did back then undoubtedly laid the foundation for my troubles."
"The moment we walked into the yard and saw my mother, a heated argument broke out between us."
"You should have found out. I am raising the assessment period. Of course I don't want the matter to get too big and bad words to come out."
"To be honest, I am very concerned about my mother's incident back then."
Tang Shouren raised his head to prevent tears from rolling down: "I want her to disappear..."
"But at the last moment, I still couldn't make the move."
"In my heart, I hope she can commit suicide."
"When I found out she was really dead, I felt relieved. Finally, it was all over."
Tang Shouren wiped the tears from the corners of his eyes, and Zhou Zhimo asked him: "You don't let us investigate, is it because you are worried about what we will find out, and it will affect you, right?"
