Chapter 758: Discovery of Clues
That night, the deceased's grandparents rushed over from their hometown.
In the conference room, the first thing the grandfather said when they met was that he wanted to take a last look at his granddaughter.
At this time, the chief police officer Huang Mao came out to coordinate, but he was very nervous at the moment and couldn't speak a word clearly in front of the victim.
Forensic doctor Lao Tang was still in the autopsy room communicating deeply with the corpse, and everyone subconsciously didn't want to disturb his work.
The expert Ma Rongcheng who came from the hall couldn't have direct contact with the family of the deceased, so in the end it was Chen Shu, a policeman from another province, who stood up.
"Old man, Xiaoli is in our forensic room. She just received our examination. Well, she suffered a little. Our forensic doctor is cleaning her up and making her clean and decent. Let you see her later, okay?"
The grandfather was dressed simply, his square face was full of sadness, and tears were rolling in the corners of his eyes.
He clenched his fists, suppressed his voice, and asked word by word with gritted teeth: "Leader, have you caught the person?"
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 to prove that someone else killed Xiaoli."
Grandpa stepped forward and pinched Chen Shu's upper arm with both hands, half of his body was shaking: "Leader, our Xiaoli will not commit suicide, and it is impossible to commit suicide! Someone must have killed her!"
Grandma cried out: "Wow, Xiaoli is such a good child, who can kill Xiaoli with such a heart of crime!"
Chen Shu paused for a while, letting the family of the deceased release their emotions for a moment, and comforted: "Please believe the police, if there is a murder case, then we will definitely give you, Xiaoli an explanation!"
After speaking, Chen Shu felt that the time was almost up, so he asked the eloquent Chen Chuan to take Xiaoli's grandparents to the forensic room to see their dead granddaughter.
With a bang, grandma fainted on the ground without any warning.
The forensic room was in chaos. Many police officers were busy carrying the old woman to the sofa while calling 110 emergency number.
Grandpa held his wife's hand tightly, tears kept falling down, and he was choking with sobs, and his emotions were also a little excited.
About ten minutes later, the sound of an ambulance came from the window, and then several medical staff rushed to the forensic room with emergency equipment and stretchers under the guidance of several police officers.
Grandma was sent to the ambulance, and grandpa followed. Before leaving, he asked the police to catch the criminal with a sad look.
After sending the two elderly people away, Jiang Hai asked in a daze: "Brother Shu, haven't we confirmed that the deceased committed suicide? Can't we just tell them directly? You still..."
"First of all, we are not 100% sure." Chen Shu remembered that when he was in the hotel, the deceased asked the hotel cleaner to come to the room to clean the next morning.
Would someone who wants to commit suicide care about hygiene?
Or did she want people to find her body as soon as possible?
But after the check-out time, someone will naturally come into the room to check, so why bother?
I feel that there is still some logic missing.
Chen Shu turned around and taught: "The two old people are old and can't stand the tossing. Before we get a sufficiently accurate result, we can't tell them the result casually. Moreover, we have to think of some way to give them spiritual sustenance.
"When the time comes, we will officially inform them of the result. No matter what, after so much time has passed, they will slowly accept the fact that their granddaughter has died emotionally. "
After that, Chen Shu went back to the forensic room.
Jiang Hai was thoughtful.
As a trace expert from the provincial department, Ma Rongcheng had actually prepared to go back to the scene for re-inspection before coming to the Criminal Investigation Department. However, considering that he was just a technician from the department who came to assist in solving the case, it was not convenient for him to go directly to the scene, so he went to the Criminal Investigation Brigade first.
But when Xiao Huang from the local Criminal Investigation Department spread the photos of the scene on the table one by one, Ma Rongcheng, who had worked in front-line criminal investigation and now focused on the study of traces at the scene, just glanced at it and was sure that the photography skills were solid and there was a high probability that he would not need to go back.
Old Tang is a forensic doctor, and he usually disdains to do this. Xiao Huang has only been in criminal investigation for a few months and doesn't know anything, so it's obvious who took these photos.
Although he was not very comfortable with the sudden intervention of criminal investigation colleagues from other provinces in local cases, 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, ready to do something practical to open everyone's eyes and know what technical work is.
After a while, when Xiao Huang filled the table with photos and enjoyed the attention of everyone for a while, Ma Rongcheng coughed a few times and looked at Jiang Hai, who was not very energetic.
"Young man, the show is about to start. "
Jiang Hai, who was slumped in a chair and doing nothing, heard this and wondered if he should jump up to cooperate with the expert from the provincial department. Then he saw the other party take out a telescopic ruler from the investigation box and started talking.
Ma Rongcheng pointed to several photos of footprints at the scene 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 varied. Generally speaking, our focus will be on other shoe prints left at the scene, extracting them one by one, and then checking them one by one."
"Yeah, this is a formal procedure." Jiang Hai touched his chin and said seriously. This kind of actual combat is not easy to come across for a student of the police academy.
Of course, the most important thing is that expert Ma gave him hope.
Ma Rongcheng deliberately paused and smiled: "But in this case, my suggestion is to focus on the shoe prints of the deceased and eliminate all other shoe prints!"
In terms of murder cases, the first thing the police need to know when they arrive at the scene is who else was there at the scene besides the deceased.
And comparing the shoe prints left at the murder scene can be said to be one of the basics and the first thing to consider. After all, shoe prints can represent people.
So Ma Rongcheng's proposal to go against the grain immediately attracted everyone's attention and curiosity, and this was also the result he wanted.
"The shoe prints of the deceased? What's so good about her shoe prints?" Jiang Hai was a little confused, but he seemed to have grasped something.
Chen Shu, who was standing by, followed his habit and put himself in the scene of the deceased's stay in the hotel. He imagined his habit of staying in the hotel these days, and then analyzed it in connection with the shoe prints mentioned by expert Ma.
Seeing Jiang Hai thinking hard, Chen Shu took the opportunity to remind him softly: "Try the substitution method."
"Substitution method" Jiang Hai changed his thinking and pondered according to Chen Shu's special teachings in the past few days, "If I were staying in a hotel, I would take off my shoes as soon as I got to the room, because it would be comfortable. Well! As a hotel resident, shouldn't she wear slippers?"
Jiang Hai's breathing became rapid, and he was sure that he had grasped the key point.
"I have 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 believe you all think that this is the mark left by the deceased, so this batch of shoe prints was first excluded during the on-site inspection, but the problem lies in this batch of shoe prints!"
