Coming to the technical squadron, Peng Sijue told Chen Shi: "There are only two people's fingerprints on the packaging of Zhonghua Cigarettes, Teacher Liu and Teacher Yan, and Teacher Yan's fingerprints are distributed like this..." Peng Sijue showed him a simulated picture.
As a former smoker, Chen Shi could see that it was the fingerprints left when the cigarette was opened. He said: "Mr. Yan stole the cigarette. Are there his fingerprints on the trophy?"
"There are no fingerprints on the trophy. It is wiped cleanly, including blood stains. If it weren't for luminol reagent, even blood stains would not be found."
Chen Shi picked up the trophy on the table, with the structure of this thing, either holding it with both hands or holding it with one hand, Chen Shi said: "If this thing leaves spattering blood on the bottom, how do you do it? "
"Pick it up with one hand and swipe hard!"
"Where are you hitting?"
"According to common sense, such a dull and heavy object will only have so much blood when it is hit on the head. The blood vessels under the scalp are the most dense. If you use it to hit the body, you may only bruise and not bleed on the spot."
"The office is most likely the scene of the murder. Someone dealt with it afterwards... Teacher Yan has quit smoking for many years, why did he suddenly steal a colleague's cigarette to smoke, and the ashes fell on the blood."
"You can't be regarded as evidence. The person involved can compose a hundred kinds of explanations, as long as there is no dead body now!"
Chen Shi's expression dimmed, and he muttered, "There must be a master to help, could it be him..." Then he walked away in despair, and Peng Sijue realized that he had taken the trophy a minute later.
Chen Shiman was thinking about it. When he drove the car to the house, he discovered two things. First, he forgot to pick up Tao Yueyue; second, there was a trophy in the passenger seat.
Once he fell into hard thinking, he would be like this. He patted his forehead, took out a cigarette from his arms, took a cigarette, hesitated again and again, but still did not point, and started the car to pick up Tao Yueyue.
When he came to the bureau the next morning, Chen Shi was a little sluggish. Lin Dongxue sniffed at him and said, "You have a hangover?"
"No... I had some wine last night."
"I thought you were both happy and angry, and this little thing made me depressed."
"Drinking was because I was so tired yesterday, not because of this." Chen Shi defended, "Any progress?"
"I was about to tell you that I received an anonymous call to the police last night. The other party deliberately lowered his voice and provided a clue, saying that he heard Teacher Yan and Teacher Lin quarreling on September 30. What was the'principal' mentioned in the quarrel. With words like'despicable', Teacher Yan's car didn't leave school until 8 o'clock in the evening, and there was no Teacher Lin in the car."
"Well, anonymously call the police? Maybe I called."
"No way!?"
"I mean, this police call can't be used as evidence. The other party doesn't even know his identity. The lawyers in the court can say that we forged it."
"But anyway, it gave me a clue."
"Actually, I suspected this teacher Yan last night, fingerprints, blood stains, soot, something must have happened between him and Teacher Lin on the evening of September 30th."
"Look for him now?"
"It's a bit early! A bit early..." Chen Shi considered, "Let's go to Teacher Lin's house."
Teacher Lin is worthy of being the daughter of the deputy director. Her family bought her an apartment near the school. The two of them came here with their father. The house is exquisitely decorated. The door is a sofa set, and the living room is tidy and clean. There is also a piano.
Father Lin said: "Xiao Xiao has loved music since she was a child. When she was a child, she won prizes in the city's children's music competition. Alas, if we can support her dream more, it won't happen today."
"What happened today, do you mean..." Lin Dongxue asked.
"Isn't there a rumor that she ran away with the rock ex-boyfriend? Didn't you investigate?"
"We are also following up on this clue. The boy is currently on tour and not in the local area. However, Lin Xiaoxiao's ID card information shows that she has not bought a ticket or air ticket in the past. Does she have a car?"
"She can't drive, the school is close, so it's not necessary."
Chen Shi asked: "Who said this rumor."
"In the school."
"How do you say it specifically."
"Some people say that because she was dissatisfied with the family's arrangements for her, she endured it for too long, and suddenly left without saying goodbye." Father Lin sighed again and shook his head.
"I have one more sentence, you see as a father, does she have a bad relationship with her current boyfriend Yan Ke?"
"Very good! That boy, although his family background is average, but he really worked hard to make progress. He has eaten at home several times. My wife especially likes him. I feel relieved to entrust my daughter to him. Last time he came. At that time, I also bought a lot of health care products, all of which were aimed at my wife’s disease."
"Your lover's disease?"
"She has high blood pressure and myocardial infarction. Alas, she can't help it when she is old. She has just had a stent operation a while ago and has been hospitalized."
"But you said earlier that on October 1, three people in the family are going to have a meal."
"Yes, on National Day, it is rare to have time. I went to the vegetable market early in the morning to buy some vegetables and came back to cook. Her mother also took time off and went home from the hospital to get together, but she didn't expect that she would leave when she said something was going on. …"
"September 30, are you at home alone?"
"right!"
The main purpose of coming today is to collect teacher Lin’s fingerprints and DNA. Chen Shi paid special attention to the shoe rack, entrance and bathroom. No outsiders should have come in here. Lin Dongxue made a discovery. She found an unopened one in the cabinet. Foot washing machine.
Father Lin said unexpectedly: "Why did she buy another one?"
"Is it exactly the same?" Chen Shi asked.
"Yes, it's exactly the same. I saw this brand on TV. One time I joked that I wanted one to try, but I didn't know that the kid wanted to write it down. She actually bought two."
From the various signs in the house, Teacher Lin did not leave suddenly. She did not take any clothes, turn off electrical appliances, or even a credit card or ID card.
After going downstairs, Chen Shi said to Father Lin, "Did you two use the footwashing machine?"
"Open it on the same day."
"Is the box still there?"
"Yes, make a den for the family dog!"
"I want to take the box back for inspection."
"What's so good about this, but if you insist..."
At noon, the two took back the packing box of the footwashing machine. It was verified that there was Lin Xiaoxiao's fingerprint on it, which made Chen Shi doubt his previous conjecture. Could it be that she was really alive on October 1st
At this moment, the sub-bureau called and said that a female body was found in the suburbs, and the entire second team rushed to the scene immediately...
