Liang Yi sighed.

I didn't expect that this time I would be like this scene at Qin Peng's house. Whether it is good or evil, when this person dies, everything is finalized.

No matter what, we must find the real murderer.

Liang Yi wore thin wire gloves to avoid leaving traces on the items, and walked up the stairs step by step. "Have the footprints on the stairs been collected? There are also fingerprints and palm prints on the handrails of the stairs!"

Zhou Haiyang's voice was loud, "It has been collected, there is no preliminary determination, and there is no valuable information!"

Zhou Haiyang pointed to the open door of Qin Peng's residence, "The door and door handle were also collected. The result was too unexpected. There was no fingerprint at all, and Qin Peng's fingerprints were not available. Qin Peng lived here every day, going up and down the stairs, how could there be no fingerprints on the door handle? The only reasonable explanation is that the person who killed Qin Peng did it, and the murderer should have done it. It is very professional. We have no way to know what he used to remove fingerprints. It is initially suspected that it is a hydrochloric acid compound."

Liang Yi turned his attention to Zhao Minghui, just collecting evidence from Zhao Minghui. Is Zhou Haiyang true? There is no fingerprint, and he has also been treated with hydrochloric acid compounds.

Zhao Minghui and Liang Ji have been with each other for many years, so of course they understand what Liang Yi means. "Zhou Haiyang is right. Since Han Qi left, this kid can finally study traces and criminal investigations with all his heart."

"I initially concluded that the murderer should have used a spray of hydrochloric acid compound! This compound is not very corrosive, so there are not many traces left. The spray spray on the door handle wiped out all the clues of fingerprints."

Liang Yi noticed that Qin Peng'an was particularly hidden at the door, and the small red dot on it turned into a dark color, which means that the camera is in a state of off and the power supply should not be turned on.

"Where is this camera?"

"I have also checked it!" Zhao Minghui pointed to the camera and said, "I found out from the beginning that the camera was turned off, and the hard drive used for storage inside was taken away! There was no clue."

Liang Yi asked again, "Did you find anything abnormal in the stairwell?"

"Liangtou, except for a cigarette butt found in the stairwell, this cigarette should be a fireworks cigarette in our Haigang City! No other things were found! The community where Qin Peng lives is still a high-end community. The property fee can reach three yuan per square meter a month. The cleaning work is done well, and there is nothing. At present, the cigarette butt is called processing and testing results, and it needs to be tomorrow."

Zhou Haiyang put on disposable shoe covers and was the first to enter Qin Peng's home.

Qin Peng has completed the preliminary evidence collection at home, and there are many physical evidence tags filled with numbers on the ground.

"How did Qin Peng die?" Liang Yi initially found that the living room was very neat and there were no signs of fighting. After looking at the door lock and door handle, he did not pry it. The person who killed Qin Peng should be an acquaintance.

"Qin Peng's death was in his study, and someone cut his throat! The forensic doctor initially identified that the person should be standing behind Qin Peng. At that time, Qin Peng was sitting on a chair next to the desk! He cut off the trachea and arteries at the same time, and blood sprayed the table!" Zhou Haiyang said.

Several people came to Qin Peng's study, and Qin Peng's body had been transferred to the forensic studio of Haigang Police Department for further review and demonstration. A series of examinations were also required to test whether there were alcohol, toxic ingredients in Qin Peng's body, and whether there were particularly excessive blood indicators.

Liang Yi felt something hanging on the ceiling, and there was a strong sense of oppression. When he looked up, he saw that it was indeed the yellow paper cinnabar talisman of the Beimosai people.

A large piece of dark red blood splashed out from Qin Peng's desk, and there were also traces of blood on the white wall opposite.

Zhao Minghui paced back and forth in Qin Peng's study, "It's so evil! A few days ago, he admitted that he killed Ma Li from the mental hospital and was still detained in the detention center for this reason. Later, the lawyer hired by Qin Peng raised objections, and there was no way to accuse Tiankong! "

"One night, I thought it was over one night! I suddenly received it. Qin Peng called me, and Qin Peng said that someone was going to kill him! This man was walking back and forth in the corridor, waiting at Qin Peng's doorsteps for Qin Peng. Qin Peng said that it was the wronged soul of the Beimosai tribe who locked his life! Qin Peng asked our police for protection! At that time, I thought Qin Peng had something wrong? I heard his tone as if he had drunk too much."

"When did Qin Peng call you?" Liang Yi looked at Qin Peng's study, which was very clean and tidy. The only thing that had dirt and was more annoying was the only thing left with a few blood stains, without any trace of struggle.

"It should be the night before yesterday!" Zhao Minghui recalled, "Actually, Qin Peng had expressed his desire to ask our police for protection from the day he was acquitted."

"Qin Peng is sitting on this chair!"

Zhao Minghui pointed to the solid wood chair, "Qin Peng is really rich, and his desk is made of solid wood."

Liang Yi held his cheek with one hand and squatted down to observe, "My opinion is that an acquaintance committed the crime. After this man killed Qin Peng, he should have stayed in the house for a while. All the places where fingerprints might be left are processed. Has the ground been processed?"

Liang Yi smelled a very slight smell of Eight 4 disinfectant. The ground should be dragged by the absorbed Eight 4 disinfectant. The purpose should be to destroy some footprints or hair.

"The ground has also been processed! And I was very serious. I didn't find anything valuable on the ground." Zhao Minghui was so worried that he turned pale. "Now Qin Peng is dead too! Zhang Yaxin's case and Du Yan's case? Will it become a unsolved case!"

"How is Qin Peng's initial interpersonal relationship investigation? With the permission of the telecommunications department, we can investigate Qin Peng's mobile phone call records and text messages."

"All these are done! Qin Peng doesn't use his phone very much." Zhao Minghui smiled helplessly, "We really met our opponent! It's the yellow paper cinnabar talisman again. Now this murderer not only kills pregnant girls. What kind of mess are the Beimosai people?"

"It's just that Han Qi stopped doing it at this time. It's really a hell."

"Liangtou, you met Han Qi in the ancient city. How is Han Qi's condition? I always doubt whether the Beimosai tribesmen have brainwashed Han Qi!" Zhou Haiyang was also very worried about Han Qi. A girl lost contact in another place, and it has been more than a few days.

"Han Qi's state..."

Liang Yi paused for a moment, "It's pretty good. Han Qi wants to be alone, it's nothing wrong! This is her freedom."

"Did the residents nearby ask? Are there any witnesses or people who heard the news?"

"No!" Zhou Haiyang did this a few hours ago, "No one saw any suspicious person."

Liang Yi remembered that when he walked into the unit door, he needed a password or an access card to come in. "Now the first thing we need to do is to check it out! Qin Peng's interpersonal relationships. Find if there are any suspicious people!"

Zhao Minghui's cell phone rang.

He is a colleague of the Third Criminal Investigation Detachment. He received feedback from the telecommunications department. In the past few days, Qin Peng has contacted anyone on his mobile phone and who calls Qin Peng.

Some time ago, Qin Peng was detained in the detention center and his mobile phone was turned off.

Only records in the last few days.

Zhao Minghui looked at his cell phone, "The person who contacted Qin Peng these two days is He Biao! Lin Weishan, Sun Kun, director of the Academic Affairs Office of Haigang University. There is also a strange number I don't know."

"Why is it He Biao again?" I never remembered the scene of trying to use hypnosis on He Biao for the first time. "Will this He Biao really have a problem? He has evidence of being absent every time, will it be forged?"

"Old Zhao, Zhou Haiyang, you two hurry up and interrogate these people! Feng Wei, go back to the forensic doctor in the bureau and stare at me to see if there is any latest evidence."

"After collecting evidence on the spot, the cordons downstairs were removed, the police car was also removed, and told the property management staff of the community that we should leave completely."

"Liangtou? This is not right, the crime scene needs protection." Feng Wei asked back.

"There is nothing to protect. The crime scene was cleaned up too clean. Let the news go out." Liang Yi said, "I will hide in Qin Peng's house tonight, and I may have unexpected gains."
Chapter completed!
