Liang Yi let out a long sigh.

I didn't expect that this time I would visit Qin Peng's home to see such a scene. Whether a person is good or evil, when that person dies, everything will be finalized.

No matter what, we must find the real culprit.

Liang Yi put on light thread gloves in order not to leave 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 and clear, “We have collected everything, there is no preliminary identification, there is no valuable information!”

Zhou Haiyang pointed to the open door of Qin Peng's residence, "Fingerprints were also collected on the door and the door handle. The result was beyond my expectation. There were no fingerprints at all, not even Qin Peng's. Qin Peng lives here every day

Living here, going upstairs and downstairs, on the door handle

How come there are no fingerprints on it? The only reasonable explanation is that the person who killed Qin Peng did it. The murderer should have done some processing. It is very professional. We currently have no way of knowing what he used to remove the fingerprints. Preliminary

It is suspected to be a hydrochloric acid compound."

Liang Yi turned his attention to Zhao Minghui to collect evidence from Zhao Minghui. Is what Zhou Haiyang said true? There were no fingerprints, and it was also treated with hydrochloric acid compounds.

Zhao Minghui has been working with Liang Ji for many years, so he certainly understands what Liang Yi means when he sees him, "Zhou Haiyang is right. Since Han Qi left, this kid can finally concentrate on studying trace science and criminal investigation."

"My preliminary conclusion is that the murderer used a hydrochloric acid compound spray! This compound is not highly corrosive, so there are not many traces left behind. The spray was sprayed on the door handle and erased all fingerprints.

clue."

Liang Yi noticed that the small red dot on Qin Peng'an's particularly hidden micro camera at the door turned dark, which meant that the camera was turned off and the power supply should not be turned on.

"Where's this camera?"

"I've checked it too!" Zhao Minghui pointed at the camera and said, "I discovered as soon as I came to the scene that the camera had been turned off and the hard drive used for storage had been taken away! There are no clues."

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

"Liangtou, except for a cigarette butt found in the stairwell, this cigarette should be our Haigang City's Fireworks brand cigarettes! I didn't find anything else! The community where Qin Peng lives is considered a high-end community, and the property fee per square meter per month is

It can reach three yuan. The cleaning work is good and there is nothing. The cigarette butt is still being processed and the test results will be released tomorrow."

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

Qin Peng has completed preliminary evidence collection at home. There are many physical evidence labels with numbers written on them on the ground.

"How did Qin Peng die?" Liang Yi initially found that the living room was very clean and tidy, with no traces of a fight. He looked at the door lock and door handle and found that they had not been pried. The person who killed Qin Peng should be an acquaintance.

"Qin Peng's death place was in his study. His throat was cut! Preliminary identification by the forensic doctor showed that the person should have been standing behind Qin Peng. Qin Peng was sitting on the chair next to the desk at the time! The knife was cut and the trachea was cut at the same time.

And arteries, blood spurted all over the table!" Zhou Haiyang said.

Several people came to Qin Peng's study. Qin Peng's body has been transferred to the forensic studio of the Haigang City Police Station for further examination and demonstration. It is also necessary to test whether there are alcohol components, toxic components in Qin Peng's body, and whether there are any special blood routines.

A series of inspections such as excessive indicators and so on.

Liang Yi felt like something was hanging on the ceiling, giving him a strong sense of oppression. When he looked up, he saw, as expected, it was the yellow paper cinnabar talisman of the North Mosai tribe.

A large area of ​​dark red blood spattered on Qin Peng's desk, and there were also scattered traces of blood on the white wall opposite.

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

We can only acquit Tian Tian!"

"One night late at night, I think it was about one o'clock! I suddenly received a call from Qin Peng. Qin Peng said that someone wanted to kill him! This man was pacing back and forth in the corridor, and he was in front of Qin Peng's house.

Qin Peng could hear his footsteps while waiting. Qin Peng said it was the wronged soul of the Beimosai tribe that locked his life! Qin Peng asked our police for protection! At that time, I thought there was something wrong with this Qin Peng? I listened to him

He sounded like he had drunk too much."

"When did Qin Peng call you?" Liang Yi looked at Qin Peng's study. It was very clean and tidy. The only thing that was dirty and unsightly was the few blood stains left. There was no sign of any struggle.

"It should have been the night before yesterday!" Zhao Minghui recalled, "Actually, Qin Peng expressed his desire to request the protection of our police 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. A set of desks are all made of solid wood."

Liang Yi held his chin with one hand and squatted down to observe, "My opinion is that an acquaintance committed the crime. This person should have stayed in the house for a while after killing Qin Peng. All places where fingerprints may be left will be processed.

Has the ground been treated as well?”

Liang Yi smelled a very slight smell of August 4th disinfectant. The ground should have been dragged with the absorbed August 4th disinfectant, in order to destroy some footprints or hair.

"The ground has also been treated! And it was very serious. I didn't find anything valuable on the ground." Zhao Minghui turned his head with sadness, "Now Qin Peng is dead too! Zhang Yaxin's case and Du Yan's case? Yes

It’s not meant to be a mystery!”

"How is the preliminary investigation of Qin Peng's interpersonal relationships? And with the permission of the telecommunications department, we can investigate Qin Peng's mobile phone call records and text message records."

"All of this is already being done! Qin Peng doesn't use his cell phone very much." Zhao Minghui smiled helplessly, "We really have 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 just so happens that Han Qi doesn't want to do it at this time. What a hell."

"Liang Tou, you met Han Qi in the ancient city. How is Han Qi's condition? I always wonder if the Beimosai people have brainwashed Han Qi!" Zhou Haiyang was also very worried about Han Qi, a girl.

I lost contact in other places for more than a few days.

"Han Qi's condition..."

Liang Yi paused for a moment, "It's not bad. Han Qi wants to be alone, which is understandable! This is her freedom."

"Did the nearby residents ask? Are there any witnesses or anyone who heard the noise?"

"No!" Zhou Haiyang had done this a few hours ago. "No one saw anyone suspicious."

Liang Yi remembered that when he walked into the unit door, he needed a password or an access card to come in. "The first thing we have to do now is to check! Qin Peng's interpersonal relationships. Look for anyone suspicious!"

Zhao Minghui's cell phone rang.

It was a colleague from the Third Criminal Investigation Detachment who received feedback from the telecommunications department. In the past few days, who had Qin Peng contacted on his mobile phone and who had called Qin Peng.

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

Only records for the last few days.

Zhao Minghui looked at his phone, "The people who contacted Qin Peng in the past two days are He Biao! Lin Weishan, Sun Kun, the director of the Academic Affairs Office of Harbor University. There is also an unknown number."

"Why is it He Biao again?" I never remembered the scene of interrogating He Biao for the first time and trying to use hypnosis on He Biao. "Is there really something wrong with this He Biao? He has alibi evidence every time.

Could it be forgery?"

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

"After the on-site evidence collection was completed, the cordon downstairs was removed, the police cars were also withdrawn, and we told the property management staff of the community that we should leave completely."

"Liang Tou? Isn't this right? The crime scene needs to be protected." Feng Wei asked rhetorically.
Chapter completed!
