Luo Yanlin received a message from Lu Xiaotang, through the QQ video to Lu Xiaotang and Murong Yuchuan said: "From what you told me, the body has a variety of scars, and all appear irregular state, as you guess, this is a typical abuse injury."I would also like to ask Murong Yuchuan, is these injuries left before or after death?”

"All injuries left behind before death, and not a murder weapon, unfortunately, the police on this side have not found any murder weapon."This is not the first crime scene.”Murong Yuchuan said.

“Where are the victims’ injuries?”

“There is no single fatal injury, and the comprehensive analysis is due to the functional failure of important tissue organs such as the liver under mechanical damage.”

"That is to say, the murderer did not have a clear purpose of killing, and what he did to the victim Tian Xiaoxia was completely a kind of xie-like destruction/disamination."This is a sadistic act, the murderer is pure pleasure in abuse, the victim's life is not on the heart, as for the killing, is only the result of the abuse, or simply the murderer's simple desire to extermination.”

“Do you think the killer could be a child?”

"Child?" in the video, Luo Yanlin's expression was slightly shocked, "How do you ask this, have you already caught the murderer, is it a child?"

"Now the police have detained four high school students, all of whom are in the same school as the victims.Because witnesses have seen them take the victim in the car.”

In general, teenagers are impulsive, and it is possible to create sudden cases that can be violent, but it is rare for you to describe this purely abusive purpose.Usually sadistic crimes occur in adults, autistic people, people with neurological problems, or people with sexual yu inverted people will show a tendency to violence during adolescence or earlier in their early years, arson, folding/brasting animals, etc., but these lines are temporarily in the development stage and will not immediately cause substantial harm to others.Until these mentally abnormal people enter adulthood, and after entering society, the pressure that usually adults face often becomes a trigger for their criminal yu.As you have just described to me, in my usual experience, the murderer's age should be relatively old, male between the ages of 30 and 50.

“That means teenagers can be excluded, right?”

"It can't be said that everything is an accident, I just say according to the past situation, I can't be 100% sure."Since the South City Branch determined that the murderer was a child, there must be a reason for them.You may wish to investigate and make a conclusion.”

Lu Xiaotang hesitated for a moment and asked Luo Yanlin, “Then can you give a picture of the suspect now?”

“My present picture cannot be accurate, and the information you gave me is too simple.But I can give you a few directions to investigate and help you identify the suspect’s characteristics.First, you have to determine whether the relationship between the murderer and the victim is a stranger or an acquaintance.This requires understanding the victim's address, daily arrangements, habits, hobbies, and whether there are any special manifestations before and after the victim's disappearance, etc., so as to determine whether the murderer's understanding of the victim is a stranger or an acquaintance.If it is an acquaintance, it is necessary to further understand each other's relationship."

"The second is the 'ficrant's familiarity with the crime scene', including whether there are houses, buildings, and companies nearby."There are also instruments of crime and criminal methods.This can help you determine whether the offender is planning a crime or a random crime, or even more useful clues.”
