Four days later, there was a new discovery in the case.

Li Xueming came to the Criminal Police Brigade to report the situation. Tian Chunda and Hao Dong received him.

"What do you have to report?" After the three of them sat down, Tian Chunda asked Li Xueming.

"Teacher Tian," because Tian Chunda was over forty years old, Li Chunming politely called him teacher. "I thought about it carefully, this murderer and the person who framed me should be by my side, and I thought about using a fishing bait to lure him into appearance."

Tian Chunda and Hao Dong both stared at Li Xueming with interest when they heard this.

"What bait did you use?" Tian Chunda asked.

"Three days ago, I was playing poker with three of my classmates, two of whom were from our dormitory, Du Hui and Qian Yongjin. The other is Xin Ran from the dormitory next door.

In the course of playing poker, I seemed to inadvertently mention that I had some thoughts about this recent case. Several students were very interested. Let me tell them about it. I said that my thoughts and analyses were written in a journal. I haven't fully considered maturity yet, and when I think about it, I have to show it to the criminal police first, and then you will see it after getting affirmation. At this point, I had locked the diary with a strand of hair and wiped the smooth plastic cover clean, if someone peeked at the diary, the hair lock would be broken and fingerprints would be left. I think the murderer has already peeked at my diary, and when he hears what I say, he is likely to peek at my diary again to understand my thoughts and analysis of the case, and to be prepared. ”

"Sure enough, the murderer acted." Tian Chunda looked at Li Xueming and said.

"Yes." Li Xueming nodded. "After lunch today, I went back to the dormitory, checked the diary I had put in my bag, and found that the hair that was coded had been torn open, indicating that someone had stolen the diary and opened it. Then, this murderer is most likely among the three classmates who played poker with me. ”

"Did you bring the diary?" Tian Chunda asked.

"Brought. I was holding a gloved diary, and I was holding it on the edge, for fear of destroying my fingerprints. Li Xueming put on his gloves again and carefully grabbed the edge of his schoolbag and took out the diary.

Hao Dong also put on gloves at this time, carefully grabbed the edge of the diary, put it in a plastic bag, and then took it to the technical appraisal room to identify fingerprints.

Soon the identification came out. The murderer also stole the diary with gloves on, leaving no fingerprints.

Li Xueming, Tian Chunda, and Hao Dong were all disappointed.

Li Xueming shook his head and said, "This criminal is really cunning!" ”

Tian Chunda said: "It's like a college student, a person with a high IQ who commits a crime. ”

Hao Dong said: "However, he still couldn't hold his breath and showed his feet. Now the search for the culprit has been narrowed down to a small one, among the three poker players. ”

Tian Chunda said: "We must make persistent efforts and strive to win as soon as possible." He shook Li Xueming's hand again and said, "You are very smart, and your thinking and arrangement are very helpful to us." ”

Li Xueming said: "As soon as there is a new situation, I will report it again." ”

"Okay, thank you for your help." Tian Chunda clasped his hand and said.

"Is this also to free me as soon as possible?" Li Xueming said.

On Sunday, Tian Chunda's wife said that her chest was a little stuffy and she wanted to go out for a walk. Tian Chunda hasn't rested for more than a month, and he hasn't gone out with his wife for a few months. He felt a little guilty in his heart, and said to his wife, "I have some time today, let's go out with you for a walk." ”

When his wife heard this, she was very happy: "Can you go out with me for a walk?" It's a rarity. Let's go for a walk in the park. ”

"Good. We can go wherever you want. Tian Chunda tried his best to make his wife happy.

"Which park are we going to?" The wife asked.

"Let's go to Starlight Park."

The husband and wife came to Starlight Park. The two of them walked for a while, and Tian Chunda led his wife to the big tree where Minin was attacked. The two sat on a bench under the tree and chatted for a while, and Tian Chunda stood up.

"What are you going to do?" The wife asked.

"This is the location of a case, and I want to check around again to see if I can find any more suspicions and traces." Tian Chunda said.

"You, even when you are resting, don't forget to solve the case. I said why did you want to go to Starlight Park, it turned out that I still wanted to solve the case. The wife laughed and complained.

"You sit down and rest, and I'll look around here. It's also equivalent to accompanying you. Tian Chunda said with a smile.

"Look, look, if you don't watch, you'll be restless." The wife laughed and complained again.

Tian Chunda carefully looked around, carefully observing step by step. At this time, he felt that someone was watching him, and when he looked up, a man a few meters away turned his head around. This action caught his attention, and he walked over to the man, a park sweeper, in his fifties, dark and thin, dressed in overalls and holding a broom in his hand.

"Hello, I'm a police officer." Tian Chunda took out his ID and showed it to the sweeper. And he said, "You know that there was a case here the other day, right?" ”

The sweeper nodded slightly, "Yes." ”

"Have you spotted any suspicious objects or people in this area lately?" Tian Chunda stared at the other party's thin face and asked.

The other party hesitated for a moment, then hesitated and shook his head.

Tian Chunda saw all this in his eyes and thought to himself, this sweeper must know something. He asked, "Looks like you might know something." Please tell me what you know. We police are anxious to solve the case. You see, I was walking with my wife to the park on Sunday, and I was still here to search for clues. ”

"I ......," the sweeper wanted to say, but stopped.

"Please help us, thank you. If you can provide valid clues, there will be a reward, and the minimum reward can be more than 1,000 yuan. Tian Chunda said earnestly to the sweeper.

"You police are really hard, I saw your behavior just now. I was also quite impressed. I, I'll tell you. ”

Tian Chunda stared at the sweeper's eyes, expecting him to continue.

"I, when I was cleaning up the garbage the other day, I found a black plastic bag in the garbage bin, tied to the mouth, but there seemed to be something inside. I took it out and opened it, and there was a black hood inside, which was quite new. I thought of the notice issued by the Public Security Bureau, and thought to myself that maybe this hood was worn by criminals. ”

Tian Chunda's eyes lit up when he heard this, and he asked, "Why didn't you report to the police at that time?" ”

"I, I went home and told my wife, but my wife wouldn't let me report. Fear of causing trouble. She said that if you get into trouble, it will be troublesome, those people kill people without blinking, if they know that you have reported the crime, the accomplices may seek revenge on you. Me, I didn't report it. ”

Tian Chunda said: "Don't worry, we will not reveal the person who reported the case, and we will keep it strictly confidential." Where's that hood now? ”

"In the warehouse where we put our cleaning tools and tooling."

"Let's go, I'll go with you to get it."

Tian Chunda and the sweepers came to the warehouse where the cleaning tools were placed in the park. The sweeper opens a cabinet where the overalls are placed and takes out the black plastic bag.

Tian Chunda stopped him: "Slow down." He took out his gloves and put them on, took out the plastic bag, opened it to look at the hood inside, and said, "I'll take this back and identify it." If it's really a criminal's hood. You'll be rewarded. Thank you for your support of our work. What's your name, please? ”

"My name is Yang Changsheng."

"Thank you, Old Yang." Tian Chunda clasped Lao Yang's hand and said goodbye to him.

Returning to his wife, Tian Chunda said to his wife excitedly: "This trip is really not in vain, I have found important clues!" Let's go, I'm going to the Public Security Bureau right away. ”

"Look at you, you said that you were accompanying me to the park, but it turned out to be looking for clues, and when you find clues, you leave." The wife laughed and complained.

"Let's go, I'll go to the Public Security Bureau, and I'll buy you your favorite roast duck when I come back."

"You, with this advantage, will coax people." His wife laughed and walked away with him.

The Public Security Bureau's technical appraisal office removed some fingerprints from the black plastic bag sent by Tian Chunda, and removed a hair from the hood. The police then managed to obtain Xin Ran's fingerprints and hair. After fingerprint comparison and hair DNA comparison identification, it was proved that the fingerprints on the plastic bag were Xin Ran and the sweeper Yang Changsheng; The hair on the hood is spicy.

The police immediately arrested Xin Ran and interrogated him. In the face of conclusive evidence, Xin Ran had to tell the truth:

"I have a jealousy against Li Xueming. He was my main contender for graduate school. I have the feeling of 'both Shengyu and He Shengliang', if it weren't for Li Xueming, I would have grasped much more if I was admitted to graduate school. Later, I happened to look through Li Xueming's diary and found that he had a crush on Julie, and I also had a crush on Julie, and I loved it very deeply. Therefore, I am even more jealous of Li Xueming, because he is still my rival. After Julie's case came out, I was very angry at Minin for setting up a trap to kill Julie, and wanted to take revenge on Minin for avenging Julie. I just want to take the opportunity to frame Li Xueming. This kills two birds with one stone.

I went to the dance party on the evening of August 2, went to the toilet halfway, jumped out of the back window of the toilet, went to the balcony on the third floor of the student dormitory building opposite, stole Li Xueming's blue striped T-shirt, and then ran into Starlight Park, put on a hood, and hit Minin, who was sitting on a bench under a big tree, knocked him down with a hammer, and then tore off the small chest pocket of Li Xueming's T-shirt, stuffed it into Minin's hand, and closed his hand. After that, I threw the hammer into the lake in the park and put the hood in a black plastic bag and threw it in the garbage bin because I was afraid that if I threw the hood into the lake, it would float. Then I ran back to school, sent Li Xueming's T-shirt back to the balcony, and went back to the dance. ”

"How do you know Minin will be at Starlight Park on the night of August 2nd?" Tian Chunda asked.

"I followed him, and he went for a walk in Starlight Park every night and sat on a bench under that big tree to rest and review his English."

You continue. What about later? ”

"After that, I sent two anonymous letters to the public security department typed on the computer, leading the troubles to Li Xueming. When Li Xueming said that he had thoughts and analyses about the case and recorded it in his diary, I really wanted to see it as a precaution. So I peeked at Li Xueming's diary again. After reading it, I regretted it again, thinking that this might be the bait set by Li Xueming, but it was too late to regret it. Speaking of this, Xin Ran lowered his head.

After interrogating Xin Ran, Tian Chunda said to Hao Dong: "I saw a sentence in the book, 'Jealousy is the devil', it seems to be true." ”

Hao Dong nodded and said, "Competition is encouraged now, but unfair competition can also lead to tragedy." ”

"Hmm." Tian Chunda nodded.
