Detective: Start with capturing and retrieving the dog

Chapter 64 Premeditated
"Mr. Han, don't be tempted by his words." Lu Wenbo frowned, "No matter how poor your experience is, it's not a reason to commit a crime. Don't think he is innocent just because you sympathize with him."

"Of course not." Han Xin shook his head: "There are three bases for my judgment that he is not the murderer."

As he said that, Han Xin raised his first finger: "First, what does it mean that there is no DNA on the victim's body? The suspect took insurance measures, probably using a condom. In other words, this crime should have been premeditated. But if Tao Wei is the murderer, then this crime is an impromptu crime, and it is impossible for him to prepare this thing in advance."

"Then what if he happens to have it in his car?" Lu Wenbo shrugged, "Maybe he usually goes out to find a lady, or uses it at home with his wife?"

Han Xin turned his head and looked at Tao Wei on the other side of the glass: "He has to work ten hours during the day, and he has to drive an online car-hailing car after work. He can only sleep for four hours a day, and he is still short of money. I don't think he has extra money and energy to find the lady. As for him and his wife, they are expecting a child now, so they probably wouldn't prepare this thing? Even if they did, they wouldn't put it in the car."

Everyone at the scene looked at each other in blank dismay, and Wei Bin said lightly from the side: "Based on this alone, it's a bit far-fetched, right?"

"Of course it's more than that," Han Xin said, holding up his second finger. "Second point, the victim was violently beaten before she died. According to the forensic doctor's judgment, she was beaten at least 30 times by the murderer...Why did you do this?"

"To control her? To prevent her from resisting during the invasion." Hu Chen came to a conclusion.

"The unreasonable thing is," Han Xin shook his head, "If you want to control the other party, there is no need to fight like this. Especially the victim is still a anchor, basically relying on her face for food. After her face is attacked a few times, she should compromise. But look at the victim's face..."

Han Xin picked up the photo and looked at the highlights marked by the eagle eye: Zhang Shiyu's entire face was swollen from the beating, and he couldn't even open his eyes.

"Excessive violence..." Lu Wenbo held his chin and said, "Is it possible that the murderer has a tendency to abuse?"

"Unlikely in this case." Han Xin shook his head. "The biggest characteristic of impromptu crimes is that the murderer usually completes the crime as soon as possible. If he abuses the other party in this way during the assault, his crime will last for a very long time, increasing his risk of being discovered. Judging from the time Tao Wei came and went, it is impossible for him to have so much time to do this."

"So, the only possibility of this kind of excessive beating is to vent your anger." Huo Gang sighed.

"Exactly." Han Xin nodded, "This kind of venting behavior shows that there is obviously some contradiction between the murderer and the victim. They should have known each other before and had a long-standing grievance. If we contact the pre-work of preparing condoms before, we can prove that this case cannot be an impromptu crime."

"It's reasonable." Zhao Linshan nodded seriously, "What about the third point?"

"Fingerprints." Han Xin looked at the highlights on the scene report, "Don't you think the distribution of fingerprints is strange? One of the reasons why the police determined that Tao Wei was the murderer was that the door lock was intact, which indicated that the victim opened the door on his own initiative. At that time, Tao Wei told Zhang Shiyu that he was going to return the watch, which created the conditions for him to open the door."

"Fingerprints..." Wei Bin mused, "If the victim opened the door on his own initiative, then there should be no fingerprints of Tao Wei on the outside of the door. And the courier who found the body saw that the door was open, which means that the murderer didn't close the door when he left. Therefore, there should be no fingerprints of Tao Wei on the handle outside the door."

"There is Tao Wei's fingerprint on the handle outside the door, which means that he opened the door himself, not the victim." Hu Chen suddenly realized, "He said that the door was open when he went, so he was telling the truth!"

"Also." Han Xin continued, "The victim's house is full of Tao Wei's fingerprints, but her clothes are not. Isn't that strange? If Tao Wei didn't wear gloves, fingerprints would definitely be left on the clothes during the sexual assault."

"It means that the murderer wore gloves and gloves, but this kid didn't." Lu Wenbo looked at Tao Wei in the detention room and said, "It's really not this kid..."

"But these cannot be used as evidence of his innocence. At present, he is the most suspected." Huo Gang glanced at Tao Wei in the detention room and said, "If you want to clear him of suspicion, you still have to find key evidence or catch the real murderer."

"From [-]:[-] a.m. to [-]:[-] a.m. the next morning, Tao Wei was the only one who entered and exited that building. How can this be explained?" Hu Chen frowned, "This is an ironclad proof."

"What kind of ironclad evidence is this?" Han Xin laughed, "What if it's someone in this building? The murderer was already in the building before two o'clock in the morning. After committing the crime, he returned to his home, so he didn't have to go in and out?"

"I'm such an idiot!" Hu Chen slapped himself on the forehead.

"Everyone's thinking is constrained by the existing evidence." Han Xin explained, "Because everyone has already identified Tao Wei as the prisoner, under the habit of thinking, they subconsciously guide the existing evidence to him. This is a very common mistake in profiling. Using profiling to compare someone you have already suspected will lead to too narrow results."

"It means that you can't first find someone you think is suspicious, and then force him to profile him." Hu Chen had an enlightened expression, "I really learned it, Teacher Han!"

What is this woman doing?Is it your turn to lick other people's fiancé all the time?If I want to lick, I will lick... Zhao Linshan thought sourly on the side, and vigilantly pulled Han Xin to her side.

"So the murderer is someone from the building. This can explain why the victim opened the door on his own initiative, but... what is his motive?" Lu Wenbo asked in puzzlement, "I usually don't look up and look down, can't I?"

"She is a female anchor." Han Xin reminded, "There are many possibilities. Maybe someone in the building discovered her identity as an anchor; it may also be because she usually broadcasts live broadcasts at night to disturb the people; or it may be that the big brother lurks in the building in advance."

Immediately, Han Xin paced back and forth: "But what confuses me the most is that Tao Wei didn't see anyone in the room when he came to return the watch. Logically speaking, the murderer should have controlled the victim at that time. Why was there no one?"

After thinking for a while, Han Xin raised his head: "The crime scene is not Zhang Shiyu's home, but the murderer's home."

"I always feel like it's getting more and more chaotic?" Huo Gang rubbed his temples irritably, "Shouldn't your job be to make our investigation easier?"

"My job is to help you catch the real culprit." Han Xin smiled slightly, "Hurry up and investigate, Captain Huo."

(I'm going to test the waters next week, please follow up. The grades of this book are not good, and the test is only a month old, and criminal investigation is unpopular. Follow-up is very important, please everyone.)
