Chapter 360 Clues of Conflict
Unlikely, it proves that he is not the same person in the unit.
However, the shoe prints of Wang Huifang’s husband Zhang Chao are basically printed on the top of all the shoe prints.
This means that Zhang Chao was the last person to enter the room.
Or is there something wrong with the time of death determined by the medical examiner?
Lu Chuan opened the case file again and read through it carefully.
According to the records, focused investigations were conducted on everyone whose fingerprints and shoe prints were found in the room.
Although the file does not record who is the key suspect and who is the subject of the investigation, but based on the normal way of handling the case, the husband of the wife who was murdered is basically one of the biggest suspects.
But in this case, there is relatively little investigation content about Zhang Chao, because Zhang Chao has a clear alibi.
Only four people’s confessions were recorded in the file, and they could all guarantee that Zhang Chao was not at home when the crime occurred.
How can we kill people when no one is here?
So, Zhang Chao’s suspicion was cleared from the beginning.
Of course, if Zhang Chao is really the murderer, then there are two possibilities.
First, the person who testified against him was lying.
But it is easy for one person to lie, but the possibility of four people lying is too small.
In other words, Zhang Chao was indeed not at home when the crime occurred.
According to the file records, Zhang Chao reported the crime on July 3, Monday at 6:32 pm. After returning home from get off work, he found that his wife had been murdered, so he called the police.
The time of death recorded by the forensic doctor was around 12 o'clock in the morning on July 3rd.
At this point in time, Zhang Chao participated in an internal discussion meeting at his unit, and four people collectively testified for him.
So, unless Zhang Chao’s colleagues collectively commit perjury, Zhang Chao must have been in the workplace when Wang Huifang died.
So is there a second possibility that the time of death determined by the medical examiner is inaccurate?
Of course this possibility exists, but the probability is not high.
According to the file records, an autopsy was performed on the deceased because he was murdered. The time of death obtained by the medical examiner was based on a variety of factors.
The autopsy report is attached to the file.
Although Lu Chuan was not a forensic doctor, he could only judge from the perspective of current investigation, rigor mortis degree records, corpse temperature records, etc., that the forensic doctor should have no problem in judging the time of death of the deceased.
However, there is no problem with the two inference questions. What is the final problem?
Thirty sets of superimposed footprints were found in the bedroom, the living room, and the bathroom. The top footprints all belonged to Zhang Chao.
Logically speaking, it is impossible for the murderer to sneak into Wang Huifang's home and commit the murder without leaving any traces.
The situation at that time was that the murderer did not clean up the scene after killing the people. This is very clear in the investigation report.
Fingerprints aside, if the murderer wore gloves, it would be normal for him not to leave any fingerprints, but what about the footprints?
There were no traces of cleaning on the ground at the crime scene, which meant that the murderer's footprints would definitely remain at the crime scene, and it was impossible for the other party to drift in.
Theoretically speaking, the footprints left by the murderer at the crime scene should be the latest and cover all other footprints.
Of course Zhang Chao found his wife dead after coming home from get off work and then reported the crime, so part of his footprints should have covered the murderer's footprints.
But it is impossible to cover them all, because according to Zhang Chao's transcript, he smelled the smell of blood when he returned home and opened the door, and then saw his wife lying in a pool of blood in the second bedroom at the door.
At that time, he did not even enter the second bedroom and reported the crime directly.
That is to say, Zhang Chao did not enter the second bedroom when he reported the crime.
His footprints will not cover the footprints left by the murderer in the second bedroom.
So, if Zhang Chao’s transcript did not lie, why were the superimposed footprints in the second bedroom his? After careful thinking and analysis, Lu Chuan felt that it didn't make sense.
On the one hand, judging from the analysis of the footprints, Zhang Chao is the murderer.
But he has a perfect alibi.
What on earth is going on?
After a while, Lu Chuan collected the materials and decided to report it.
As a technical criminal police officer, his work has been completed. Now if he has any doubts, he can just report them to the leader.
What is the situation? Is it a forensic problem or Zhang Chao's problem? Just pool everyone's wisdom and restart the case investigation.
Of course, it is not Lu Chuan's decision to restart the case investigation alone. His current investigation and analysis of the footprints can only be said to be indirect evidence, a piece of inferential evidence.
This evidence challenges the possibility that Zhang Chao was not at the scene, so it must be clarified.
There is also another possibility. If the murderer really did not leave any traces at the scene, it is not impossible that he used some special method.
Crunch.
Lu Chuan, who had just packed up the materials and was about to go out, saw the laboratory door open.
"Captain Qin?"
Lu Chuan was surprised: "Why are you here?"
Qin Chuan was followed by the office director, with drinks like Red Bull in his hand: "Xiao Lu, Captain Qin He said you've been working too hard these past two days, so I came here to express my condolences."
Qin Chuan looked at Lu Chuan with a very kind expression: "How are you? I've been under a lot of pressure at work recently. Can you stand it? If not, take some rest. , Don’t rush to solve the case, you have to combine work and rest.”
“Thank you, Captain Qin, for caring about me. I’m fine. It’s quiet here in the laboratory. It’s good to calm down and work on it. I can also master some of it.” Knowledge is consolidated and consolidated.”
"Haha, being young is good. When we were young, ah, it was common for us to go out to run cases and not sleep for days and nights. Now that we are older, our bodies are not forgiving."
"Captain Qin, you are But as the backbone of our detachment, we still need to learn from you."
"We can only hold on for the past two years, and the future of the detachment depends on you."
" No, they just called you about the case you helped Liangzhou City examine two days ago, saying that they had made a big discovery and wanted to thank you."
Lu Chuan was slightly surprised, that case of dismemberment?
I have been busy with the detachment's backlog of cases these past few days, and I almost forgot about that case.
"Has that case been solved?"
He only gave a guess at that time, and there was no substantive evidence.
Qin Yong shook his head: "We have a target of suspicion, and the other party may be involved in a different case. By the way, I just called over there and said there was a fingerprint. See if you have time to help take a look. . ”
“That’s no problem. I’ll take a look when the case in hand is finished. ”
Lu Chuan nodded. Identifying fingerprints was not a big deal to him.
"The case in your hand? What case?"
"Oh, just the backlog of murder cases in our detachment four years ago."
Four years ago?
As the captain of the detachment, Qin Yong is certainly aware of the backlog of murder cases in his family.
There is only one backlog of cases four years ago, the murder of Wang Huifang.
"The case of Wang Huifang's murder...do you have any clues?"
