The members of the task force were still a little confused, but Lin Chuan had already mentioned the first suspect, so it was reasonable.
The murderer's actions showed that he was very familiar with the victim's family. Since he was familiar with them, it was mostly among his relatives and friends.
However, Wu Lin was just a street vendor. Most of his friends were street vendors, and his relatives were thousands of miles away.
He only had one family member who spent his summer vacation here. A month of summer vacation was enough for him to get familiar with this family. However, he had returned to his hometown after the summer vacation. If his travel records showed that he had returned to Hanzhou City a few days before the crime, then why would he come back? Moreover, Wu Lin's neighbors had confirmed that no one had come to Wu Lin's house these days. If he could not explain himself, he would be even more suspicious!
Qin Yin naturally understood the situation immediately. He immediately got someone to investigate Wu Lin's younger brother, Wu Hang. It was easy to check the train ticket purchase records based on his identity information.
When Wu Hang's ticket purchase information appeared, Qin Yin's gaze was already firmly locked on the ticket purchase record from a week ago. The record showed that Wu Hang had taken a train to Hanzhou a week ago, and he had never left since he arrived!
However, when the police arrested Wu Lin's family, it took Wu Hang a day to appear in front of the police!
Why did he lie? Most people who lie have something up their sleeves!
After he left, Qin Yin looked at Lin Chuan in disbelief and smiled.""If I wasn't there, Lin Chuan, I really wouldn't believe that you have such an excellent mind to solve cases. Especially your logical thinking, it's even more amazing.”
"I'm definitely not as good as Sister Qin. I've only just started criminal investigation. But now that the suspect had appeared, the relationship between the suspect and the murderer was uncertain. Therefore, whether Wu Hang was the murderer or not could only be confirmed after interrogation.”
As Lin Chuan said this, Qin Yin could not help but look at him in a new light.
A qualified criminal police officer should not be so excited when the suspect appeared and say that the murderer had been found!
Even Deputy Director Wu said with a smile,"To be honest, when I heard that someone who wasn't from the branch office had joined the task force, I was extremely disgusted. But now, I don't think so anymore. I really can't help but look at him in a new light.”
Lin Chuan just smiled and didn't say anything.
He knew very well that if he had not been baptized by the library, he would not have been able to capture the problem of the case so keenly with his previous experience.
Not long after, a police officer came over and said that Wu Hang had been brought to the interrogation room.
"Lin Chuan, come with me. You opened the gap in this case, so you should come with me.”
Qin Yin sent out an invitation, and Lin Chuan smiled and nodded as they went to the interrogation room together.
Wu Hang was sitting inside with his head lowered, deep in thought. When he heard the door open, he looked up and quickly asked,"Captain Qin, is there any news about my brother's case?”
Qin Yin did not show any emotion. After sitting down, he took out his cell phone and placed the ticket booking record in front of Wu Hang. He said,"There are indeed some new discoveries in your brother's case, but during our investigation, we found something very strange. Mr. Wu, you went back to your hometown at the end of summer vacation at the end of August. Why did you come to Hanzhou a week ago? According to our inquiries, your brother's neighbors didn't see you.”
Looking at the ticket booking record and hearing Qin Yin's words, Wu Hang's expression changed drastically. He shouted,""What do you mean? Are you suspecting me of being the murderer? Why didn't you investigate the real murderer? Why did you come to investigate me, the victim's family?”
One of the reasons why he suspected Wu Hang was because of what Wu Hang said.
The victim's family members were often the ones who were pitied. No one would suspect him, let alone investigate his travel records. If Lin Chuan hadn't mentioned it, Wu Hang would definitely have been forgotten!
As someone who relied on efficiency and iron-blooded methods to get to the top, Qin Yin would not be intimidated by Wu Hang's words. She continued to say calmly,"We are not saying that Mr. Wu is the murderer, but you have to give us a reasonable explanation. Why did you come to Hanzhou City a week ago?”
"Why should I answer your question?" Wu Hang asked coldly. Don't I have the freedom to go anywhere?”
"Bang!"
Without warning, Qin Yin's palm slammed on the table, but her tone was still very calm as she asked,""For the last time, Mr. Wu, why did you come to Hanzhou City a week ago?”
Wu Hang's eyes widened in fear. Lin Chuan looked at Qin Yin in surprise and said to Wu Hang,"If you can't explain this ticket booking record, you'll become the first suspect in this case. Remember, you still have one chance now. Otherwise, my Sister Qin will really treat you as a suspect later!”
"I…I…My brother called me here. He told me that he wanted to kill my sister-in-law and nephew. I was worried, so I secretly came to Hanzhou!”
As soon as Wu Hang's words came out, Qin Yin's gaze suddenly turned sharp. Even Lin Chuan's face was filled with disbelief.
Wu Hang's appearance was called by Wu Lin?
As for Wu Lin, one of the deceased, he actually said to his younger brother that he wanted to kill his wife and child?!
