The old lady's body leaned on an old-fashioned rocking chair, and when the body was found, the rocking chair was still swaying in the silent and closed room, and the creaking sound made Li Ming tremble with fright. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"Mom......"

The middle-aged woman finally showed the expression she should have, but Xu Tian still felt that this woman's reaction was abnormal, because the middle-aged woman paused for a full five seconds before screaming after seeing the old lady's corpse.

Xu Tian understands this psychological reaction, and in psychology, this is a manifestation of lying.

If a person pauses for two seconds and then reacts to surprise when faced with a lie, it is undoubtedly lying, not to mention that this middle-aged woman paused for a full five seconds, and Xu Tian immediately had doubts in his heart.

The middle-aged woman wanted to break into the room, but Team Leader Chen moved very quickly, grabbed the middle-aged woman's arm, and dragged her into the corridor.

"Protect the crime scene, you can't go in." Team Leader Chen said to the middle-aged woman with an indifferent face.

"It's déjà vu again." Xu Tian said, "The same sealed space, but this time there is no table in front of the old lady's body." ”

"I'll call the team and the forensic doctor over immediately, and when the investigation equipment is delivered, you and I will go in together." Team Leader Chen said to Xu Tian.

Group ...... Team leader, what do we do now? Li Ming stammered.

"Find the interrogation room immediately, the girl who came on the day of the crime, and the girl's boyfriend should also be found." Team Leader Chen shouted at Li Ming.

Li Ming hesitated for a moment, and then ran back to the police station, leaving Xu Tian and Team Leader Chen at the scene.

Twenty minutes later, other policemen quickly came to the scene of the crime, Xu Tian put on a white investigation equipment, and followed Team Leader Chen into the scene of the crime.

"It's not been cleaned for at least a month, it's dusty on the floor, it's on the sofa, there's dust in the corners of the windows, it doesn't look like a city resident." Xu Tian said.

"Why is the rocking chair still shaking? The smell of this corpse is rotten, it has been almost three or four days since she died, even if this rocking chair was shaking when the old lady died, it should have stopped by itself for so long, right? Team Leader Chen said suspiciously.

"Humph!" Xu Tian sank his face and said with a dark smile. "It's very simple, when we opened the door and came in just now, we must have touched something that made the rocking chair shake, or there were people here before we came, except for these two cases, it is impossible to have a third case."

"It's a bit impossible that we opened the door and touched something, I didn't hear anything other than the sound of the door opening, it looks like someone came in before." Team Leader Chen said categorically.

"But there are only the footprints of the two of us on the ground, but this does not mean that no one has come, this kind of case is very worthy of the challenge, how did the rocking chair shake, why did the murderer let the rocking chair shake? Was it before we came, what happened when the murderer returned to the scene of the crime and accidentally touched the rocking chair? Or did the killer deliberately let the rocking chair shake in front of us? These are all criminal minds worth investigating. ”

"Is there any difference?"

"Of course it's different, if the murderer deliberately made the rocking chair shake in front of us, it means that the murderer is provoking us, and it can also be understood that the murderer is laughing at us, which means, you are here to arrest me? I'm here to show off my criminal modus operandi before you. ”

"Isn't that ridiculous? Does the criminal still have time to think about these things? ”

"If the deceased had just died, perhaps it was an impromptu attempt to kill, and then a secret room that seemed to have no loopholes was arranged. But the opposite is true, you can tell from the smell of the corpse that the deceased has been dead for three or four days, and to be honest, I have great admiration for your professionalism, but again, if the deceased has really been dead in this closed house for three or four days, then the murderer has three or four days to complete the secret room, and the method of setting up the secret room will definitely be more perfect than the impromptu setting. ”

"The only one who can kill can be the daughter who lives next door, right? When the locksmith opened the lock just now, I found that the room was locked outside with a key, and the old lady did not lock it indoors. ”

"No, this is indeed a secret room, because the naturally formed dust on the ground is enough to say everything, the rocking chair is placed in the living room near the window, the window is locked inside, there is no furniture around the rocking chair, the only sofa is leaning against the corner of the living room, and it is full of naturally occurring dust, looking at this dust through the sun, absolutely no one has stepped on it."

"Does this mean that the crime scene is a secret room? The door is locked from the outside, so as long as you have the key to the old lady's house, anyone can do it, right? And even if you don't have a key, it's not impossible to open the door, for example, a locksmith uses a tool to open the door. ”

"You forgot the main question, I guess, you don't usually live at home, and spend most of your time at the police station and crime scene, right?"

"You...... What do these do, you ask? Does it have anything to do with the case? ”

"It's very related, because your professionalism is very good, and it is a very powerful skill to distinguish the time of death of a corpse from the smell, and the first thing people feel when they smell the putrid smell of a corpse is disgust and horror, but you are still thinking about the problems related to the case, and you actually told the time of death of the corpse. But you don't know much about life, and if you think about it simply, don't you think there's too much dust in this house? ”

"So what? The old lady's legs and feet are not dexterous, so it's normal not to clean them, right? ”

Speaking of this, Team Leader Chen suddenly understood something, the pupils of his eyes had spread very widely, and his eyeballs were about to fall out.

"Do you understand?"

"This ...... No way...... How could such a thing happen? ”

"No matter how incredible you think, this absolutely perfect secret room has indeed succeeded, because there is no trace of the old lady's life in the room, and the dust on the floor must have accumulated for more than a month, but there are only our footprints, and there are no footprints of the old lady herself, even if the old lady's legs are not dexterous, there must always be some traces of activity, right? But judging by the dust generated by this room, the old lady has not been active in this house for at least a month. It's been less than a month since the last apartment dumping incident, right? The police questioned the old lady when the apartment dumped the body, and if the old lady lived in the room at that time, there would not be any traces of activity in the house, if I guessed correctly, the last time the police questioned the old lady, it should have been in her daughter's house, right? But now that the old lady is dying in her rocking chair at home, how did the old lady get put in front of the window opposite the security door without stepping on the dust on the floor? So it's a perfect room murder. ”
