The police officers took Sun Daqing to a closed room, and Qin Ranran stained his hands with some red ink.

"Let's go." Qin Ranran said to Sun Daqing.

Sun Daqing took a step, and the red ink fell down his hand to the ground, continuing to the door, pushing the door and closing it.

His series of movements were all done according to Qin Ranran's instructions, strictly simulating the actions of the crime scene.

After calculation, Qin Ranran came to the conclusion that this Sun Daqing was the murderer.

Whether it is from the height of the blood stain or the bloody handprint on the door, the height of the form is very consistent with his physical characteristics.

"It's almost finalized!" Xiao Wang let out a sigh, "Fortunately, I caught this old boy, otherwise I don't know how many girls would have been killed." ”

"Waiting for money, why do you have a bitter and hateful expression? Victory is in sight, are you not happy? Guo rebelled against Wu Dao.

Wu Dao said, "It's a little too early to draw conclusions, so let's wait for the appraisal results." ”

His words left those present scratching their heads.

Qin Ranran even felt that he was questioning his professionalism, Wu Dao said that he didn't mean that, but he just felt that it was too smooth and wrong.

Guo Rebellion felt that his nerves were too tense and he should go back to rest.

Two days later, Gen Hao found Wu Dao with the identification report, and the results showed that the DNA was more than 99% similar, and the fingerprints also matched.

Guo rebelled and put his arms around Wu Dao's neck, "Facts speak louder than words, the case is solved." ”

"A few things missing." Wu Dao calmly pushed his hand away, "Chen Xue's fingers and underwear." ”

Everyone calmed down and looked at Wu Dao in unison.

He continued, "Now the evidence we have can only determine that Sun Daqing is related to Pan Lili's death, but it cannot confirm that Chen Xue's death is related to him, and the finger and underwear that Chen Xue was taken away were not found in Sun Daqing's room, and these details still need to be explained by him before he can draw conclusions." ”

Soon, the second arraignment of Sun Daqing began.

The facts are in front of him, but he resolutely refuses to admit that he killed Pan Lili and Chen Xue, and even gets a little emotional, wanting to try to prove his innocence by dying.

"If all this is acted, then this Sun Daqing's acting skills are really superb." Xiao Wang sighed.

Wu Dao walked towards Sun Daqing, "Regarding Pan Lili's death, we have enough evidence to prove that you are the murderer, and someone has witnessed you in Chen Xue's case, you can't quibble, but we want to know where are the fingers and underwear of Chen Xue that you took away?" ”

Sun Daqing gritted his teeth, "I didn't kill anyone!" I plead not guilty! I don't know Pan Lili and Chen Xue! What am I doing with my fingers, it's just a piece of stinky meat! I'm not a pervert! Don't try to wronged me! ”

"Use some other tricks, it's useless to spend it with him." Xiao Wang said to Wu Dao.

After Ling Hai's approval, the police officers took Sun Daqing to the alley where Chen Xue was killed and asked him to identify the scene.

Under normal circumstances, suspects usually have an emotional breakdown when they return to the crime scene and tell the truth, because that kind of memory will always stimulate their sensitive and fragile nerves, and gradually break down their psychological defenses.

Sun Daqing is an exception, he walks around the alley with a very natural expression.

"Either he's a bloodless antisocial personality, or he's really not involved in the case." Wu Dao said.

Xiao Wang was also confused, now all the characteristics and clues point to Sun Daqing, all of them match, but he does not admit guilt when he dies, and the crime scene is so calm and calm, and completely unfamiliar, very strange.

In Pan Lili's house, he felt even more frightened when he saw the blood stains all over the ground, and refused to go in, and the whole person was in a trembling state.

If he was a brutal man by nature, sadistic and bloodthirsty, who would molest corpses after death, would he be so afraid of blood?

At Wu Dao's suggestion, a criminal psychoanalyst conducted a psychological test on Sun Daqing, which showed that he had certain psychological problems, but found no abnormalities in terms of violent tendencies and antisocial personality.

At the case discussion meeting, Wu Dao expressed his doubts for everyone to discuss.

Guo Meng felt that it should be the reason why Sun Daqing was a habitual offender, so he had super high psychological quality and also understood the police's case-handling process.

Qin Ranran agreed with Guo Ranran's statement, "Fingerprints, bloodstains, and movement trajectory simulations, each of which shows that it is Sun Daqing, these are the most intuitive evidence, and it cannot be said that he is innocent because he does not admit it." ”

Zou Lianya glanced at Wu Dao, "Do you think it is necessary to uphold the principle of never suspecting guilt?" ”

Wu Dao nodded, "There are too many suspicions, it seems that there is no problem with the chain of evidence, but there are many things that cannot be justified, such as Zhao Weiguo and Sun Daqing After communicating, they made an appointment to find Pan Lili, during which the two left each other's phone numbers, but this number is not Sun Daqing's, it is currently shown that it is no longer in the service area, Sun Daqing's number is still available, secondly, Sun Daqing's family did not find the murder weapon and Chen Xue's finger, the physical evidence is not right, and there is a little confirmation from the hotel owner who Sun Daqing does odd jobs, His hands were indeed scratched when he was washing dishes due to broken porcelain. ”

Gen Hao, who was sitting in the corner, proved this, "I have seen his wounds, and the wounds on Pan Lili's body are not caused by the same murder weapon, Pan Lili's wounds were left by sharp blade wounds, and his characteristics are indeed consistent with the scratches of porcelain pieces." ”

"Sun Daqing shouldn't be a murderer." Wu Dao said suddenly.

Ling Hai was stunned, "Wait for money, this matter can't be joked, who else can he have?" Fingerprints, blood, and DNA are all his! ”

Wu Dao sighed, "I don't know what's going on at the moment, but there must be something wrong here." ”

Ling Hai asked, "You said that Sun Daqing only relied on your intuition?" ”

"There is a significant difference between Sun Daqing and the murderer." Wu Dao looked at the root number, "Whether it's Pan Lili or Chen Xue, judging from the formation of the scars, they are all caused by the right hand, and Lao Jiang's head is also on the upper right, right?" ”

Nehao replied, "Yes, without a doubt. ”

Wu Dao looked at Xiao Wang again, "In the interrogation room, he asked me for cigarettes, how did he take it when I handed it to him?" ”

Xiao Wang recalled, "I took the cigarette with my left hand, and he called out when he pulled the wound." ”

"The murderer is a right-handed person, how can he scratch his right hand with a knife in his right hand when he commits the murder?" Wu Dao asked everyone a question.

Qin Ranran took the pen and gestured, "This is very difficult to do." ”

"The murderer should have injured his left hand." Wu Dao speculated, "If Sun Daqing is not the murderer, and we put all our attention on him, it is likely that we will miss the opportunity to capture the real murderer, and innocent people will be killed." ”
