Wang Zhi wiped his fingerprints, which was definitely a fatal mistake. If it weren't for the fact that the door was too clean and abnormally clean, maybe Luo Chuan wasn't so sure that there must be something wrong with him. Initial suspicion is just a normal reflex reaction. The first discoverer, the person closest to the deceased, is the first suspect target. But later, Luo Chuan saw something different in Wang Zhi's eyes. Especially when he said that people are already dead, and it doesn't make a difference whether they solve the case or not.

The innkeeper saw that Luo Chuan and the three of them were chatting hotly, so he looked at the Pixiu with blank eyes, and cautiously pointed and said, "This...... Is it confiscated? ”

Chen Xi smiled helplessly: "Don't worry, we don't want it." I just need to bring it back to have my fingerprints taken, and if there is a corresponding, it may be used as a crop certificate first. But you baby, you'll definitely get it back in the end. ”

The boss was relieved when he heard this, and quickly nodded and said, "Okay, okay, you can do whatever you want, take it away!" ”

If you really talk about it, this guy is still quite heavy, and there must be at least a hundred or so coins in it. Each one needs to be carefully checked for fingerprints, which is really not an easy job.

Thinking that the process of comparing fingerprints was a bit cumbersome, Luo Chuan walked out of the hotel and said to Chen Xi: "Let's go back and control Wang Zhi first, and then confirm the forensic wound report." You hurry up and check the fingerprint results. Once it is consistent with our reasoning, then take Xu Lan and the evidence to me together. Because it was Wang Zhi's first case, we had to start with him and investigate the case together. ”

Chen Xi said confidently: "Don't worry, I think this case should be as good as you think." I'll get it done as soon as I can, and you guys wait for my news. ”

"Okay, no politeness, we'll go back in a while, no need to send it, let's get busy!" Luo Chuan was afraid that Chen Xi would be embarrassed to go directly, so he simply opened his mouth first and asked him to go back.

As expected, Chen Xi happily left with the Pixiu in his arms. Luo Chuan likes his style of doing things very much, not false, not polite, case first, and resolute.

Turning his head to look at the second captain, it seemed to be quite heavy at this moment.

"What's the matter, you're starting to worry about that bitter man?" Luo Chuan asked deliberately.

The second captain did not fight back angrily, but sighed and said, "If this grandson is really a cross-city exchange killing, I will be the first to spare him...... I believe in him so much! But Luo Chuan, you can listen well, I'm not a woman's brainless, I'm looking at the evidence first! The evidence does prove that he didn't have time to commit the crime! And looking at him crying, it doesn't look like he has a motive for committing the crime, does it? ”

Luo Chuan did not continue to ridicule the second captain, but said very seriously: "When we solve the case, the most important thing is the evidence. In court, the most important thing is evidence. All our reasoning investigations are based on evidence, without which everything is empty talk. But, second team, you have to know that evidence can sometimes deceive us. When we encounter cunning criminals, they will use the evidence to prevent us from solving the case. At times like these, you can't just rely on evidence, you have to see beyond the evidence. For example, these inexplicable coincidences, such as the inseparable husband and wife relationship between Wang Zhi and Zhang Tong. ”

The second captain was also a rare one to listen to Luo Chuan quietly, and then he sighed and said, "Hey, maybe what you said is right, but I still don't want Wang Zhi to be the murderer." The second captain was affectionate and serious, with a hint of sadness and disappointment.

"We don't want to, okay, let's go back first! If we rush back now, we can all rest for a few hours. By the way, Guan Shan, if they meet and don't admit it, it will be up to you at that time. After getting in the car, Luo Chuan said to Guan Shan.

Guan Shan was looking at his phone at the moment, and when he heard Luo Chuan call his name, he came back to his senses and said: "If the fingerprints match, it can only prove that Xu Lan went to the hotel and used a fake identity, but it can't prove that the two of them know each other, which is indeed a problem." But I think, Luo Chuan, if you want to exchange killing, you must need absolute trust. Either they have each other's handles, and they have to do this thing to kill. When the time comes, you are responsible for the bitter male protagonist, and I am responsible for the heroine of the dual identity, as long as you can hear the relationship between them through their subtle facial expressions and verbal loopholes, it will not be difficult to break their trust. I still don't believe that there are two absolute strangers in this world who bet on this. After Guan Shan finished speaking, he looked down at his mobile phone again, as if he was busy with something.

Luo Chuanzhi, who was driving, glanced at Guan Shan, and then asked casually: "Is it the patient who relies on you a lot?" I don't seem to have seen you go to the hospital much in the last few days. How's that patient doing? ”

Guan Shan put away his mobile phone, smiled faintly and replied: "Fortunately, some diseases cannot be cured overnight." ”

Hearing this, Guan Shan still didn't want to say more, so Luo Chuan didn't ask more. What's more, the second captain is still in the car, but on the way back, he has been silent and sullen. He usually has a bold personality, and this will not happen.

It took more than two hours to return to the police force, and it was already late. Luo Chuan patted the second captain on the shoulder and persuaded, "You, don't think about it so much!" Tomorrow, you go and pick up Wang Zhi, and the truth will soon be revealed. Go sleep and recharge your batteries, there's so much more to do! ”

The usual relationship is like two people who are incompatible, and the atmosphere is quite harmonious at this time. The second captain nodded, said "You guys should rest too" and walked towards his office.

Luo Chuan asked Guan Shan again: "Are you going home to rest, or are you here?" Looking at your absent-minded appearance, is something going on? ”

Guan Shan looked at Luo Chuan for a while, and then said as he walked: "It's just that some things make people feel very uncomfortable, even if they have seen too much, they will still be very uncomfortable." I'm fine, I'll wake up tomorrow. I know, you should go to the medical examiner's office by now and ask about Zhang Tong's death, right? I'll go back first, and I'll come back to you tomorrow. ”

"Okay, be careful on the road."

Luo Chuan looked at Guan Shan's back and frowned slightly. What secrets Guan Shan has, he doesn't know. But he was sure that it was a very important secret, so important that Guan Shan was a little troubled. But since Guan Shan didn't want to say it yet, Luo Chuan couldn't help if he wanted to. In the end, just shaking his head, Luo Chuan walked to the forensic office.

After knocking lightly on the door twice, Luo Chuan walked into the forensic office. Tian Zhen, who was immersed in work, heard someone come in, so he raised his head. Seeing Luo Chuan, she greeted with a smile and said, "Team Luo, you are still in the police force so late!" Didn't you say you went to a neighboring city? Didn't Professor Kwan come back with you? Tian Zhen said, and looked behind Luo Chuan.

Luo Chuan shook his head and said, "He just left, he should have gone home to rest." Why are you the only one here, Xing Lao? ”

The old man said, there was no complicated autopsy work, and he went home. He hasn't had a good rest for more than half a month in order to write some forensic science textbook materials here. We were all worried about him, and kept persuading him to go home and rest, didn't we, so we persuaded him. Tian Zhen sighed, looking worried that Xing Lao's fatigue would not be good for him.

Luo Chuan also agreed: "It's right, Xing's old age is too big, and it will be dangerous to overwork like this." By the way, there is a case on the second captain's side, and the autopsy of the corpse ......"

Before Luo Chuan finished speaking, Tian Zhen took out a report and handed it to Luo Chuan and said, "This is what the old man left before he went home, saying that if the second captain really can't handle this case, let me transfer it to you." This is the death report of the deceased in the case of the second captain. The old man said that the murderer was very stupid, and even a few stabs in the chest failed to give the deceased a fatal blow. The deceased's chest was covered with shallow scratches and stab wounds, only the last knife pierced the artery, but it was not too ruthless, and it seemed that the murderer should not have much strength. The deceased had two resistance injuries on his arms and some dander was found in his fingernails, but they were too few to be identified. The old man said that if it weren't for the deceased being timid and scared, it would not be easy for such a stupid murderer not to be killed. ”

"Really? The murderer must be a novice with no experience in killing, right? Luo Chuan asked.

Tian Zhen replied: "Yes, I also discussed this issue with the old man. I heard that the murderer was a criminal who robbed and killed people, but the depth of his stab wounds was too sissy. By the way, the deceased's scalp had several minor breaks, and it looked like he had been scratched by the hair. Look, isn't it like a woman fighting? ”

Luo Chuan smiled: "Maybe, the murderer is a woman?" The time of death has been set, no problem, right? ”

"There is no problem, I have already told the second captain during the on-site autopsy before. In addition, the deceased had an abrasion on the ring finger of his left hand, which was probably caused by the murderer violently snatching the ring. Team Luo, I don't understand, why did the murderer snatch that ring? I heard that it is a small diamond ring, but if it is not carated, it can't be sold at all, no one recycles it, and it can't be sold for money. It can be said that ...... Ordinary gold is not worth much. Did the murderer snatch it so hard for money? Tian Zhen held his cheeks and looked at Luo Chuan very puzzled.

However, this sentence gave Luo Chuan some ideas. Although it is normal for robbers to snatch jewelry, as Tian Zhen said, a diamond ring that is too small is worthless and cannot be sold. In this case, snatching the ring may also be psychological. Was it the murderer who hated the wedding ring that was on the hand of the deceased? Still is...... Hate the marriage of the dead?

I still remember that Guan Shan once said that although it is a good idea to exchange killing, it is more difficult to gain mutual trust than killing itself! But if you say ...... The two people who exchanged killings have some kind of emotional entanglement, then that kind of trust can be explained!

Could it be ...... Wang Zhi and Xu Lan...... Aren't they just strangers exchanging murders?

Through Xing Lao's autopsy report and Tian Zhen's detailed description, Luo Chuan has now basically overturned the initial judgment. The murderer is not a man, but a woman is more likely to be. Only a woman with no experience in committing crimes would make the unwise choice of "asking for directions" before killing. This kind of mistake is exactly the same as Wang Zhi's practice of wiping fingerprints.

Leaving the forensic office, Luo Chuan returned to the office and sorted out the details of the entire case again. Before saying goodbye to Chen Xi, Luo Chuan also specially asked Chen Xi to help investigate that Liu Quande to see if the time when he could testify for Wang Zhi was within the time of Gao Dawei's death. In short, there are more and more evidence against the contrary, and Wang Zhi's iron-clad alibi is completely untenable.

Early the next morning, as soon as Luo Chuan opened his eyes, the second captain came.

Looking at his haggard appearance, he probably hadn't slept all night.

"What's wrong? So early, what's the matter? Luo Chuan sat up and asked the second captain.

The second captain said awkwardly: "It's five o'clock this morning...... A police officer said that Wang Zhi had left home with a travel bag. I...... He was taken down, and he was in the interrogation room. You've packed up in a moment, so let's go over together. The second captain was reluctant to say these words in his heart, but there was no way, the facts were in front of him, and Luo Chuan's reasoning seemed to be getting closer and closer to the truth.

Luo Chuan didn't say much, only responded with a "yes", and then went to wash and change clothes.

When Luo Chuan and the second captain walked to the interrogation room, the second captain glanced at his watch and asked, "Wait for Guan Shan?" ”

Luo Chuan also looked at the table below and replied, "No, he will come when the time comes." Let's go inside. ”

"That'...... Wait for Chen Xi's call? "The second captain is still not sure, after all, they don't have definite evidence in their hands now, and everything is still Luo Chuan's inference. In case this reasoning is wrong...... If you suddenly ask Wang Zhi, it may not be good. In any case, until the evidence is conclusive, he is the family of the victim.

But Luo Chuan said: "There are a lot of coins, and it will take them some time to investigate overnight." Don't wait, let's talk to Wang Zhi first. After speaking, Luo Chuan pushed the door and walked in.

See Wang Zhi again today, he is no longer the loveless look. On the contrary, there was a faint indifference in his expression, as if he was not very satisfied with what the police had done to him.

It has always been the second captain who asked for a confession before, and later it was the second captain who has always defended Wang Zhi. Today, it was the second captain who detained him at the door of his house. Wang Zhi looked at the second captain's eyes, and he was also a little puzzled and dissatisfied.

Luo Chuan didn't want to embarrass the second captain, so he took the lead in asking Wang Zhi, "Are you planning to go out today?" ”

Wang Zhi didn't have a good impression of Luo Chuan, and replied coldly: "Officer, please consider my feelings." My wife had just passed away, and everywhere here there are shadows of my life and my wife's life. If I stay here, sooner or later I'll be driven crazy by pain! I want to go out for a walk and leave this sad place for a while, can't I? ”

Luo Chuan smiled indifferently: "Yes, is there a goal?" Where do you want to go, neighboring city? ”
