As Li Ang had guessed, the final murderers in this case were the father-in-law

    and mother-in-law who lived with the deceased.The father-in-law took advantage of his son’s outing to work, and he had been

    insulting the deceased for many times.The deceased asked her mother-in-law for help, but the latter kept her tacit

    attitude in order to "do not show off her family ugliness," and even

    cooperated with her husband to imprison her daughter-in-law.During an insult, the deceased claimed to inform her husband who was about to

    return from work. His father-in-law and mother-in-law panicked, strangled him

    to death, and tried to escape responsibility by pretending to be suicide by

    hanging himself.During this process, the two dared not look directly at the dead body, and

    they even used cloth to cover their faces.Watching the TV show, the two elderly murderers whose faces were mosaicked

    were crying and confessing in the prison. Li Ang couldn''t help but laughed,

    "Too funny these people.""Ok?"Wang Fengnian cast a questioning look.Li Ang spread out his hands, "I don’t think they’re crying because they are

    sincerely repenting.In the course of their crimes, they have countless opportunities to stop the

    victim.Did they stop? not at all,The tears of criminals who actively attacked innocent people after putting on

    their prison clothes are only remorse for doing evil and be caught, fearing

    the coming punishment.Scum, always scum. "Wang Fengnian nodded noncommitantly, and asked, "Xiao Li, you have good

    reasoning skills. I heard Shanshan said that you have seen a lot of detective

    reasoning before?"Li Ang, of course, could not tell the other party that he used Xinhua

    Bookstore to read a lot of reasoning when he was in junior high school.began to use the Internet to learn a series of books such as "Criminal Science

    and Technology", "Criminal Investigation", "Trace Inspection", "Investigation

    Law" (the electronic version is available online, and the physical version is

    also available for sale)immediately smiled and nodded, "Yes, my dream when I was a child was to be a

    crime nemesis, to maintain public order, and to protect the lives and property

    of the people.""Ok."Wang Fengnian nodded, suddenly remembering something, and went back to the

    study to get some documents.These documents are all cases recently received by Yin city officials. In

    recent months, various weird things have happened one after another, and the

    grassroots officials have been so busy.Front-line operators like Wang Fengnian have not returned home for a long time

    and have had a normal meal with their family members.He took out more than 20 photos from the document bag, "What do you think of

    these photos?"Li Ang took the photo and found that the crime scene taken by the photo was

    located in an ordinary residential building.In the two-bedroom and one-living room, the hostess and hostess lay the corpse

    on the floor of the living room. There were several deep stab wounds on the

    waist and abdomen. There was a pool of blood around the body.All the cabinet doors in the room were opened, and some debris was all piled

    on the sofa. There were no ** footprints or other blood stains on the

    ground.The murder weapon, located in the narrow, light-on toilet, was a steel Western

    knife with a short handle and a smooth curved blade. It was immersed in the

    sink.There is a string of dripping blood under the light switch box on the right

    side of the wall under the sink.Li Ang looked at the photo, and asked without looking up: "Robbery?""Correct."Wang Fengnian nodded, "There is a fire ladder standing outside the window. The

    murderer sneaked into the house at night and murdered the owner of the house

    during the robbery. The place of entry and exit happened to be in the blind

    spot of the surveillance, and he was not photographed.""Well...."Li Ang flicked the photo with his finger and said, "How long is this case?""Two days ago."Li Ang put the photo on the table and said, “I’m not sure, but I suggest you

    go to the hospital or clinic near the place where the incident occurred and

    look up recent admission records.Check if there is a deep scar on the palm of the right hand. ""Oh?"Wang Fengnian frowned, "Why?"Li Ang spread out the photos on a glass tea table with melons and tea leaves,

    and pointed to a few photos.said: "The toilet in this house is quite narrow and dark, especially the light

    switch box, which is located next to the wall on the right under the sink.The only blood spot here is under the light box, and the blood dripping track

    is vertical.The blood stains in this shape were obviously dripped on the ground when the

    suspect pressed the switch.The light box is located on the right side of the sink, which determines that

    it is difficult for a normal person to reach in with his left hand to press

    the switch, and can only use his right hand, indicating that the blood comes

    from the right palm of the suspect. "He glanced at Wang Fengnian and smiled: "So, does this blood stain come from

    the suspect himself? Or does it come from the victim?I prefer to be the suspect’s own blood.If it is blood stained by the murderer from the victim, then the trace of

    blood dripping should be from top to bottom, changing from thick to light;The concentration of these bloodstains at the scene was the same, and it could

    only be caused by the murderer''s own hand injury.According to the shape of the knife, I guess it was when the murderer

    committed the murder, because the Western knife has a shorter handle and a

    longer blade.When gripped the handle of the knife and stab forward, due to excessive force,

    the blade turned against the palm of his hand, cutting the right palm of the

    suspect.As for the crime scene, there is no blood stains, and all the sundries are

    stacked on the sofa...I guess the murderer went to the bathroom to deal with his palm

    urgently~~ returned to the living room to wipe the blood on

    the floor, and then escaped from the crime scene.Finally, according to the blood volume under the light switch box,I guess his hand injury is quite serious and he must go to a professional

    institution, that is, a hospital or clinic for sutures.As long as you check if there are any injuries with cut marks on your right

    palm recently, you can easily screen them out. "After that, Li Ang glanced at Wang Fengnian, who had a calm face, and smiled:

    "Uncle Wang, you must have passed the test by now. It has been found that the

    blood belongs to the third person in the room, that is, the suspect himself.As long as there is a DNA sample, it is only a matter of time before the

    suspect is captured. "Li Ang still hides a word without saying, that is, he speculates that another

    bizarre event has occurred on a large scale in Yin City recently——The robbery and murder case is actually quite simple.Even if you don’t follow Li Ang’s speculation to go to the hospital or clinic

    for investigation, or search based on DNA samples, the official can still find

    the killer by looking at surveillance data on a large scale and relying on a

    lot of manpower.Generally speaking, the homicide case must be solved. Two days have passed

    since this case, which is enough to prove that the official manpower of Yin

    City is probably already stretched.This situation is caused by extraordinary factors randomly generated by the

    killing game.Still, another reason?Li Ang still kept a flat smile on his face, and his thoughts kept surging.
