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.
