Police Chen Shu

That night, the deceased's grandparents came over from their hometown.

In the conference room, the first thing my grandfather said when they met was that he wanted to take a last look at his granddaughter.

At this time, Huang Mao, the police officer in charge of the scene, came forward to coordinate. However, he was very nervous at the moment and could not speak clearly even half a sentence while standing in front of the victim.

Forensic doctor Tang was still having in-depth discussions with the corpses in the autopsy room, and everyone subconsciously did not want to disturb his work.

It was impossible for the expert Ma Rongcheng who came from the department to have direct contact with the family of the deceased, so in the end it was Chen Shu, a policeman from other provinces, who stepped forward.

"Old man, Xiaoli is in our forensic room. She just underwent our examination. Well, she suffered a bit. Our forensic doctor is cleaning her up and making her tidy and decent. I'll let you see her later, okay? "

Grandpa was dressed simply, with a face full of sadness, and tears welling up in the corners of his eyes.

He clenched his fists, suppressed his voice, and asked through gritted teeth every word: "Leader, have you caught anyone?"

Chen Shu asked Huang Mao to pour two cups of hot tea and said slowly: "Old man, this matter is still under investigation. There is no conclusive evidence yet to prove that someone else killed Xiaoli."

Grandpa took a step forward and squeezed Chen Shu's upper arm with both hands. Half of his body was trembling: "Leader, our Xiaoli will not commit suicide, and it is impossible for her to commit suicide! Someone must have killed her!"

Grandma cried loudly on the side: "Wow, Xiaoli is such a good child, who is this person with such a gangster heart, how can he kill Xiaoli!"

Chen Shu paused for a while, allowing the family members of the deceased to release their emotions for a moment, and comforted: "Please trust the police, if there is a murder case, then we will definitely give you and Xiaoli an explanation!"

After saying that, Chen Shu felt that time was almost up, so he asked the eloquent Chen Chuan to take Xiaoli's grandparents to the forensic room to see his dead granddaughter.

There was a bang, and grandma fainted on the spot without warning.

The forensic room suddenly fell into chaos. Many police officers called 110 for emergency help and hurriedly lifted the old woman to the sofa.

Grandpa held his wife's hand tightly, tears kept falling down, his mouth was choked with ouch and ouch, and he was also a little excited.

After about ten minutes, the sound of an ambulance came through the window, and then several medical staff rushed to the forensic room carrying first aid equipment and stretchers, led by several police officers.

Grandma was put into the ambulance, and grandpa followed her. Before leaving, she sadly asked the police to catch the prisoner.

After sending the two elderly people away, Jiang Hai asked with a confused look on his face: "Brother Shu, haven't we confirmed that the deceased committed suicide? Just tell them directly. You still..."

"First of all, we are not 100% sure." Chen Shu recalled that when he was in the hotel, the deceased asked the hotel cleaner to come and clean the room the next morning.

Would someone who wants to commit suicide still care about hygiene?

Or did she want her body to be discovered as soon as possible?

But after the check-out time, someone will naturally come into the room to check, so why bother?

It feels like the logic is still lacking.

Chen Shu turned around and taught: "The two old people are too old to bear the trouble. Before we get sufficiently accurate results, we cannot inform them of the results at will. Moreover, we have to think of some way to let them There is a spiritual sustenance.

"At that time, we will officially inform the results. No matter what, after so long, they will slowly accept the fact that their granddaughter died emotionally."

After that, Chen Shu walked back to the forensic room.

Jiang Hai was thoughtful.

Ma Rongcheng, who is the trace expert of the provincial department, had actually made preparations to return to the scene for re-examination before he came to the Criminal University. However, considering that he was only a technician from the department who came down to cooperate with the case, it was not convenient for him to go straight to the scene, so I went to the Criminal Investigation Brigade first.

But when Xiao Huang from the criminal department under his jurisdiction spread out the photos of the scene one by one on the table, Ma Rongcheng, who had worked in front-line criminal investigation and now focuses on the research of traces at the scene, just glanced at it and determined that his photography skills were solid and passed the test. There was a high probability that it was There was no need for him to go back.

Old Tang was a forensic doctor and would not bother to do this kind of thing on weekdays. Xiao Huang just came to the criminal investigation department and knew nothing about it for a few months, so it was clear who took these photos.

Although he was not very comfortable with such sudden intervention in local cases by criminal investigators from other provinces, after seeing these photos of the scene, he felt that this was not a bad thing.

Ma Rongcheng picked up a few photos and looked at them, preparing something more practical to open everyone's eyes to what technical work is.

After a while, after Xiao Huang filled the table with photos and enjoyed being in the spotlight for a moment, Ma Rongcheng coughed a few times and looked at Jiang Hai, who had no energy at all, with a smile.

"Young man, the show is about to come."

When Jiang Hai, who was slumped in his chair doing nothing, heard this, he was wondering if he should jump up and cooperate with the expert from the provincial department. Then he saw the other person pull out a telescopic ruler from the survey box and start talking.

Ma Rongcheng pointed at a few photos with on-site footprints with a ruler and said: "As a hotel room, there will be many guests coming in and out, and the corresponding shoe prints will be diverse. Generally speaking, our focus will be It fell on other shoe prints left at the scene, extracted them one by one, and then investigated them one by one."

"Yeah, this is a formal procedure." Jiang Hai touched his chin and said seriously. This kind of actual combat was a rare opportunity for him, a student at the police academy.

Of course, the most important thing is that the horse expert gave him hope.

Ma Rongcheng paused deliberately and said with a smile: "But in this case, my suggestion is to focus on the deceased's shoe prints and eliminate all other shoe prints!"

Simply speaking, when it comes to murder cases, when the police arrive at the scene, the first thing they need to know is who else was present at the scene besides the deceased at the time of the crime.

Comparing the shoe prints left at the murder scene can be said to be one of the foundations and the first consideration. After all, shoe prints can represent people.

Therefore, Ma Rongcheng's contrary proposal immediately aroused everyone's attention and curiosity, and this was also the result he wanted.

"The deceased's shoe print? What is there to study about her shoe print?" Jiang Hai was a little confused, but he vaguely seemed to have caught something.

Chen Shu, who was standing on the side, followed his habit and put himself into the scene of the deceased's hotel. He imagined his habit of staying in the hotel these days, and then analyzed it in conjunction with the shoe prints mentioned by expert Ma.

Seeing Jiang Hai thinking hard, Chen Shu reminded him softly: "Try the substitution method."

"Substitution method" Jiang Hai changed his thinking and started thinking according to Chen Shu's special teachings these days, "If I stay in a hotel, I will take off my shoes as soon as I get to the room because it is comfortable. Well! As a hotel resident, she Shouldn’t it be better to wear slippers?”

Jiang Hai's breathing quickened, and he was sure that he had grasped the key point.

"We've touched the edge." Ma Rongcheng encouraged Jiang Hai with a kind face, and then said, "The shoe prints on the ground are consistent with the soles of the deceased's shoes. I think you will all think that these are the prints left by the deceased, so we conducted an on-site inspection I was the first to rule out this batch of shoe prints, but the problem lies in this batch of shoe prints!"
