Criminal investigation crime night stealth

First, Fu Ju led people to bring back the corpse in the Black Water Forest.

Taking advantage of this time, Shen Zhinan and others rushed to the No.3 deceased's home to check the situation.

The deceased, Ms. Chen Damei, was 30 years old. She had three sons and a daughter. Her husband was working outside and was still on her way back to the city.

A yellow cordon was pulled outside the room of the deceased, and the smell of blood still lingered in every corner of the house, lingering.

In order to better protect the scene of the first crime, Ms. Chen's children were placed in a shelter in the city, so the scene was not damaged.

The situation at the scene was similar to that investigated by the police station. However, when several people were about to leave, Lu Yao suddenly discovered a suspicious point. There was a small and fresh groove on the beam of the deceased's bedroom.

Like wire marks.

Continue to look down along this trace, and find an inconspicuous groove on the uneven wall.

She glanced at Shen Zhinan, reached out and touched the groove, "What is this?"

"Have you found the murder weapon?" Shen Zhinan stared at the groove, and said in a deep voice, "It seems to be caused by the impact of a hammer."

Zuo Sandao shook his head, trying to recall the details of the case, "The murder weapon has not been found yet, there are too many such hammers."

After a pause, he continued: "There are two market days in the county every week. There are a lot of this kind of hammers in the market. Trying to find clues from them is like looking for a needle in a haystack."

He was right, every household would have one of this kind of hammer, and it would be unrealistic to find the murder weapon and the murderer from it.

"Squeak" Lu Yao pushed open the window and poked his head out.

Behind the window is the most common "yang gutter" in the farmhouse. There is still rainwater in the ditch, and the yellow and rotten leaves are soaked in the sewage, giving off a strange smell.

Is it possible for the murderer to come in here?
Shen Zhinan patted Lu Yao's shoulder, but before Lu Yao could react, the next second, Shen Zhinan jumped sideways and jumped out of the window.

Lu Yao: "!!!"

Shock!

Shen Zhinan can jump out from here with such a big man, so why can't the murderer come in from here?

just
How exactly is this done? !

Shen Zhinan patted the dust on his body calmly, "Have you seen the army training? Don't be surprised, these are all small scenes."

This made Lu Yao fall into deep thought.

Shen Zhinan, who is so big, can pass by, but with a bit of ingenuity, the murderer can also come in from the outside and hide in the room waiting for an opportunity?

Thinking of this, she knelt down to check the situation under the deceased's bed, and quickly rejected this idea.

Because this bed has no bottom at all.

The stone bed surface was only covered by the sheets, so she didn't recognize it at first.

Headache.

"Is there a possibility that it was a mechanism killing?" Qian Duoduo walked in from the door, his eyes fell on the groove.

Organ killing?
The two looked at him suspiciously.

Qian Duoduo thought for a while, "There was a murder case in a secret room abroad. The murderer set up a trap in the secret room in advance. After the victim entered the bathroom, he locked the door and touched the trap after entering the bathtub. After the trap stunned the deceased, the murder weapon melted in the water. , a perfect secret room murder case."

Hearing this, Lu Yao couldn't help but pause.

If so, then.
Wire marks on beams, grooves on walls
She reacted abruptly, "Who found the body?"

Fu Ju has other things to do, so Zuo Sandao and the others are currently following. Hearing Lu Yao's words, Zuo Sandao stepped forward.

"It's the hostess of the family on the slope. She wanted to borrow some potato seeds, but when she entered the door, she saw that the person was dead."

Lu Yao gently rubbed his chin with his fingers, "Did she see anyone else, or something extra in the room?"

Zuo Sandao shook his head, "No, I was so scared."

While the two were talking, Shen Zhinan followed the Yanggou all the way to the path behind the house.

People here seem to like to plant a bamboo grove in front of their house. The bamboo grove covers most of the house structure, and sister Chen's house is no exception.

In the afternoon, the road connects to the crop field in the back mountain. The crop field not far away has just been half renovated, and there is a ravine about ten meters between the bamboo forest and the crop field.

In addition to the rustling of the bamboo forest, you can also hear the sound of running water.

It appears that this ditch was once a river.

Lu Yao and Qian Duoduo followed, and seeing Shen Zhinan standing by the edge of the bamboo grove, she said, "Do you suspect that the murderer threw the murder weapon down here?"

"It's possible." Shen Zhinan murmured, frowning as he looked at the ravine covered in weeds.

"The children of the deceased left home for school around [-]:[-] in the morning, and they could not return until the evening. The deceased would have prepared brunch the night before, and the reporter found the deceased in the afternoon. It took at least six hours to die."

"Suppose the deceased wakes up at seven o'clock, the murderer has already arranged the mechanism, the bedroom room is not well lit, and the deceased wants to get dressed, what is the first thing to do?"

Lu Yao suddenly realized, "Turn on the light!"

Qian Duoduo has a different opinion, "In order to save electricity bills, the deceased may not turn on the lights."

"What if the murderer put something in the room in advance, forcing the deceased to turn on the light?" Shen Zhinan added.

Looking at the bamboo forest in front of him, Lu Yao instantly understood what Shen Zhinan meant.

"The murderer set the mechanism on the pull rope of the electric light. As long as the deceased turned on the light, the mechanism on the beam of the house would be touched. The deceased could not dodge in time and was knocked unconscious by the shaking hammer. Under the action of inertia, the hammer struck back and forth, eventually causing death. The dead die."

If this is the case, no matter whether the deceased finished his farm work, turned off the lights at home, or turned on the lights early in the morning, he would not be able to escape death.

The murderer patiently hid in the gutter, or hid on the mountain, and after everything was over and took away the murder weapon, he would be able to commit this murder without anyone noticing.

"But there is no trace of the hammer handle on the fatal wound." Li An hurried over.

Lu Yao curled his lips into a smile, which made it even simpler.

"Is it possible that the murderer only used a hammer without a hammer handle?"

Li An immediately understood that as for the murder weapon, the most dangerous place is the safest place.

The murder weapon is very likely to be near the deceased's house, most likely in the bamboo forest in front of him.

"Then what are you waiting for, search." Li An shrugged, and said to Zuo Sandao: "Everyone is going to work hard."

Zuo Sandao patted his head in embarrassment, "What are you talking about, if it weren't for your help, we wouldn't have thought of this level."

"It's very similar to that person's handwriting." Qian Duoduo said in a deep voice, "Could it be done by him?"

will not.

Lu Yao immediately denied this idea, "Even if he did it, he wouldn't do it himself."

Qian Duoduo was taken aback, "I actually forgot that K is best at deceiving people. He is an excellent psychiatrist. Even if he wants to kill someone, he won't get a drop of blood on his hands."

"There will be a murderer in any case." Shen Zhinan turned around, "Let's go, check the relationship of the deceased, don't be affected by serial murders, there are so many unsolved cases in this world, look in another direction, and you will find out, but Human nature is ugly.”
