criminal mentality

Chapter 91 Xiao Yu's doubts

When analyzing the case of Wang Meimei and Qin Lanlan, Wen Mo focused on watching the video sent by the murderer several times.It is very important for the murderer to send the CD to the deceased's home so that the relatives of the deceased can see the reason why the murderer killed the deceased, otherwise the murderer would not have spent so much energy in making a mystery. However, the police at the murder scene of Zheng Yueru and Dong Ting did not No disc found.

There are two plausible explanations.First, the police found the rental house in Changsheng Garden, which made the murderer wary. In order to prevent the CD from recording any information that would allow the police to deduce his hiding place, the CD was not sent.However, this possibility is not high. The criminal methods of the Zheng Yueru case are relatively consistent with the previous two cases, but the Dong Ting case is quite different from the previous three cases. The evidence obtained by the police at this stage is not enough for them to join the investigation. The purpose of making the dead man himself known to be guilty is not accomplished.

The second reasonable explanation is that the latter two deceased had no very close relatives, or finding relatives would not be able to achieve the murderer's purpose.However, the murderer's criminal marks will not change substantially.Then, at the scene of the crime, that is, at the home of the two deceased, there must be a message left by the murderer!

Contrary to the previous two cases, both Zheng Yueru and Dong Ting died at home.Home should be a place where people feel safe.

Wen Mo stands in Dong Ting's rental house.Take several photos of the scene for comparison, trying to find the information left by the murderer.

In the first two cases, there was only the body of the deceased at the place where the body was abandoned, and nothing else was left. Even a large amount of blood was found in the murderer's rented house.In the latter two cases, the things placed beside the deceased. Bleach bottles.

The murderer washed the body of the deceased with bleach, so it is reasonable to stay at the scene. However, the positions of the murderer's bleach bottles at the two crime scenes are very consistent, and they are all on the opposite side of the wall where the body of the deceased is placed. Placed casually but carefully placed.

Wen Mo immediately called the forensics department and asked them to send a staff member to the scene to bring the luminol reagent.

Luminol reagent, also known as luminol, can identify bloodstains that have been scrubbed and aged for a long time, but it also has a disadvantage: it can produce a blue light that is suspected of a blood reaction after contact with chemicals such as copper or bleach.

After turning off the lights, drawing the curtains, and spraying luminol reagent on the wall, a neat line of writing appeared: In the name of the guardian angel, I sentence Dong Ting to death.

The same handwriting also appeared on the wall of Zheng Yueru's bathroom.

There is no doubt that the four cases were committed by the same murderer.

What is the murderer's motive for killing Dong Ting?
According to the police, the 22-year-old Dong Ting's career is indeed not well-known. She is a bar hostess, but she is unmarried. The autopsy results also proved that she had never given birth to a child. It is impossible to kill her own flesh and blood, right?It really doesn't fit the profile of a murder victim.Could it be that she has some hidden secrets that the police haven't found out yet?
Just as the police were staring at Dong Ting's past, eager to find out the eighteenth generation of her ancestors, her name appeared in a police accidental death investigation report.

Three years ago, when Dong Ting was 19 years old, she helped relatives watch a 6-year-old girl during the summer vacation in the second grade of junior college. When Dong Ting took the girl out to play, witnesses testified that she beat and scolded the little girl, which caused the child Crying and rushing to the middle of the road, he was hit and killed on the spot by a car that couldn't dodge.After this incident, the girl's mother couldn't bear the shock of losing her daughter, divorced and left her hometown. The girl's father, Dong Ting's relatives, almost beat her to death at the gate of the court and was sentenced to three years in prison.In the end, Dong Ting's family lost money and settled the matter.

In all four cases, victims were directly linked to the death or disappearance of a child.But these materials are not easily accessible to anyone.

Wang Meimei's fourth daughter has been dead for decades, only the local villagers' rumors and the accidental death report in the police archives; when Qin Lanlan's daughter died, everyone saw her crying and was heartbroken, and no one outside knew that it was her own hand. Selling her daughter is only in the police file, and even the procuratorate did not pursue Qin Lanlan's crimes when she filed a lawsuit later; Zheng Yueru gave up her own child before it was born, and gave away Xiaosan's illegitimate child secretly. No one knows the child's whereabouts; Dong Ting's beating and scolding of the child was recorded in detail in the police report, but only their relatives and friends knew about it.

It is not difficult to find that apart from the unexplainable death of Zheng Yueru, the police report is a common point that cannot be ignored.

The public security system of City C has forensic expertise, and there are only two people of suitable age, Xiao Yu and Fan Lu.

Luo Aimin was very angry when he saw the list of suspects given by Wen Mo, but after reading the explanation later, he had nothing to say. The reasoning of this report is rigorous and its credibility is not low.But to make him doubt his colleagues who have fought side by side, he resists in his heart.

Fan Lu was still unconscious in the hospital when Dong Ting died, and the only suspect became Xiao Yu.In the past two days, Xiao Yu's performance was abnormal, and he often missed his post for no reason. Dong Ting's autopsy was done by another 50-year-old forensic doctor from the city bureau.

Just as Luo Aimin was actively trying to find evidence to prove Xiao Yu's innocence, Xiao Yu called.On the phone, he was not as calm and calm as usual, with a voice that was about to cry: "Brother Luo, hurry up, come to my house quickly, something has happened!"

Luo Aimin drove away without saying a word, and soon arrived at Xiao Yu's home, on the L1 floor of Hongguang Lijing.The downstairs was already surrounded by people, and Luo Aimin was able to squeeze in after showing his ID.

The door of Xiao Yu's house on the third floor was open. After entering, Luo Aimin saw Xiao Yu holding a naked woman in her arms, covered in blood, in the middle of the living room.

Seeing Luo Aimin come in, Xiao Yu hurriedly put down the woman in his arms, struggled to stand up and grabbed his arm: "Brother Luo, you are finally here, my wife, she was murdered! You must replace me Catch this bastard!"

After seeing the appearance of the deceased and Xiao Yu, the people who followed couldn't bear to turn their heads away.

Luo Aimin hastily dragged Xiao Yu to another room, asked his colleagues in the forensic department to collect evidence for him, and ordered other people to do the work they should do.Then he turned around and asked Wen Mo, "What do you think of this case?"

The deceased was stabbed in the chest, and the knife was fatal. The clothes were neatly folded and put aside, and there was also a bleach bottle in the corner, and Xiao Yu's fingerprints were found on the handle of the bottle.
Luo Aimin doesn't want to believe that Xiao Yu is the murderer, but he understands that what he can do now is not to protect Xiao Yu, but to do what he should do, to find more evidence to prove Xiao Yu's innocence or to prove that he is indeed the murderer .
