The big pit on the construction site, Lao Wang heard Mr. Zhu's assistant Manager Chen telling Da Liu that Da Liu must fill in the pit today.

Before the pit could be filled, people died.

At the construction site of the branch complex of the Third Hospital of Chunyang City, a cordon was set up by the police around the large puddle on the left side of the building.

The deceased, Zhu Dahai, a native of Miancheng, was 55 years old at the time, and was the project leader of Yunxiao Group.

When the deceased Zhu Dahai was found, half of his body was exposed in the puddle, and he was scooped up by the workers on the construction site later and placed in the open space on the edge of the pit.

The report was made by Lao Wang, the janitor of the construction site, and Lao Wang said that when Zhu Dahai was fished up, his body was hard, and he must have been hopeless, so he did not report 120.

It was the second criminal investigation team of the Municipal Bureau that took over the case, because it was a stormy day before, and the scene was a construction site, when Xiao Mo and the team members arrived at the scene, there were many people watching the excitement on the edge of the puddle.

The already muddy ground was even more messy, and the scene was almost destroyed, and the old Liu of the trace department shook his head, saying that there were very few traces that could be collected.

Forensic doctor Zhu Miaomiao made a preliminary conclusion: "A large amount of white foam can be seen in the mouth and nose, the corpse spots are light red, and there is a small amount of sediment in the mouth, which is preliminarily judged to be drowning." The corpse stiffness appeared all over the body, the acupressure of the corpse spots faded slightly, and the time of death was judged to be 7~8 hours. ”

Qi Nandao: "The water in this puddle is not deep, the water depth in the middle is only 1.5 meters, Zhu Dahai is 183 tall, what is the cause of his death drowning?" ”

Zhu Miaomiao was wearing a mask and couldn't see her expression, but her voice was obviously not good.

"Auntie, can you calm down a little, haven't I finished talking yet?"

"What else is there to do?"

"Of course, the deceased suffered a swollen traumatic injury to the back of his head, and all his limbs were fractured and dislocated, so the possibility of falling from a height cannot be ruled out, and his head hit the ground. As for the possibility of internal organ damage, further autopsies are needed to draw conclusions. ”

Gao Yanan looked up at the building and said, "In other words, Zhu Dahai should have fallen somewhere in this building last night, and just fell into this big puddle." This height doesn't seem to be low, this big puddle has not been able to stop the determination of Lord Yama to kill him, and it is really that the king of Yama wants you to die in the third watch, and he will definitely not leave you until the fifth watch. ”

Zhu Miaomiao: "It's basically like this, but this big puddle does buffer Zhu Dahai's health value, and he still has vital signs when he falls, judging that he drowned in an unconscious state." ”

The first site is located in a room on the south side of the 15th floor of the complex.

At the edge of the south window sill, scratches were found.

In order to verify that Zhu Dahai fell from here, the police conducted an experiment and found a model of about the same weight as Zhu Dahai and threw it from here, which happened to fall into the big puddle.

In addition, from the hallway to the room, the Traces Section collected two sets of footprints.

Because it was a rainy day and a muddy construction site, one of the footprints was clearly visible.

Lao Liu said that this set of clear footprints matched the size 42 leather shoes worn by Zhu Dahai.

Another group of more vague shoe prints was judged to be size 43 shoes, and Lao Liu, who has many years of experience, judged that the person wearing this size 43 shoe was about 163 to 165 tall and weighed between 45 and 55 kilograms.

It's just that the pattern pattern of this sole is more peculiar, not an ordinary shoe.

In other words, last night, in addition to Zhu Dahai, there was another person in this room.

This man is also very special, a man who is less than 170 tall and weighs no more than 55 kilograms, but wears size 43 shoes.

That is to say, this person is not tall and weighs less, but he has a pair of big feet.

So the question is, did this person appear in the room at the same time as Zhu Dahai, or did the two people appear in the same place at different times?

Lao Liu said that he couldn't give an answer, the size 43 shoe print was lighter in color and had fewer mud marks, and the reason for excluding height and weight should have appeared before Zhu Dahai in this room.

Xiao Mo said: "Is it possible that person has been waiting for Zhu Dahai in this room?" ”

Lao Liu replied: "I can't give an opinion on this question. ”

On the windowsill of the room there is a popular brand mobile phone, on which Lao Liu's assistant did not extract fingerprints.

After Yanan's analysis, some selfies posted by his circle of friends, after Lao Wang's identification, confirmed that the owner belonged to Zhu Dahai's assistant Chen Yang.

Between 9 o'clock and 11 o'clock last night, there were several missed calls on the mobile phone, and after investigation, they were all called by Zhu Dahai.

Why didn't Chen Yang answer the phone? And why his mobile phone appeared at the scene is all questions.

Ma Heiniu pointed out the question: "Team Xiao, could the owner of the size 43 shoe print be Chen Yang?" ”

Xiao Mo shook his head, definitely saying that it was impossible.

"If that person is Chen Yang, it is impossible for him to leave his mobile phone on the scene, and he also wiped the fingerprints he left on the mobile phone, isn't this covering his ears and stealing the bell?"

Sure enough, after the narration of the security guard uncle Lao Wang, Chen Yang's height is definitely more than 170, and he is strong, and his weight is definitely more than 55 kilograms.

Qi Nan walked around the room with a compass, and came to Xiao Mo at this time.

"Brother, do you think this Zhu Dahai will commit suicide?"

Xiao Mo gave him a blank look: "Use your brain, think about it, okay?" ”

Two minutes later, the baby came to Xiao Mo again: "Brother, I still think that the possibility of Zhu Dahai's suicide cannot be ruled out." ”

"Then how do you explain the presence of another person at the scene?"

"So, could it be purely a coincidence? Could this footprint be left by the staff? ”

"Lao Wang said just now that after the building was capped, the follow-up secondary structure construction has not officially begun. Who would leave such footprints? How do you explain that phone that doesn't have any fingerprints? ”

Qi Nan suddenly felt weak: "Yes, when I didn't say it." ”

Zhu Dahai's X7 BMW was parked in front of the building, the window was open, and the cab was watermarked by a night of wind and rain.

Xiao Sun, the assistant of Lao Liu of the trace department, is extracting traces on the BMW, and Sun Yue, a girl who has just graduated from school, is working very seriously.

Seeing Xiao Mo, he said: "Although there are a lot of people early in the morning, the traces of the scene are almost destroyed. But there is still a gain. The rut marks of the BMW car, three marks back and forth from the entrance. Two came in and one went out. ”

"That is to say, Zhu Dahai drove in last night and went out again, and after going out, he came back here again, and then he got out of the car without having time to close the window."

"That's right."

"What caused him to go out and come back here? Did someone ask him to come back? And it must have been a very important matter, so he didn't even have time to close the windows, which was a key point. ”
