Advocate for the deceased

Chapter 723 Characterization of Crime
Another policeman with glasses hurried forward.

"After checking, the total deposit of the deceased was about 300 million, which were stored in three accounts in three banks, and were deposited in three to four times every month. There were very few records of cash withdrawals.

The ownership of the house of the deceased was purchased by his son Bi Haitao in full in 2003.

The bank transfer records are basically to Bi Haitao, each time is only a few thousand yuan, and the rest of the month is the transfer to the hired driver, nothing else, the records are very clean, no loans or credit cards! "

Zhou Hai once again crossed out an option on the form he analyzed. After Lu Guangwen listened to the report, he looked at Zhou Hai.

"The current investigation is basically like this. I followed the surveillance team. I have intercepted the surveillance on the night of May 5 and scanned it one by one. However, the quality of the video is not high and some people can't see it clearly.

Forensic doctor Zhou, tell me about the results of your autopsy! "

Zhou Hai got up, looked around for a week, and waved at Fatty. According to the photos selected by Zhou Hai, he had created a separate folder for them, opened them in order, and photos began to appear on the projection cloth.

"I'm directly talking about the results of the autopsy. After we measured and calculated the maggots, we concluded that the time of death of the deceased Bi Jianrui was after nine o'clock in the evening on May 5."

The policeman wearing glasses who was speaking just now trembled. He probably didn't go up to the scene. Seeing these photos was really shocking, especially the magnified insects that filled the screen.

"maggot?"

Zhou Hai nodded. Seeing several police officers looking at each other, he suddenly realized that forensic doctor Yang rarely used this method to make inferences.

Turning around and pointing to the live photos behind him, he said:

"The fly is a very regular small insect that smells blood, can find the corpse within 15 minutes, and lay eggs in the wound of the corpse within an hour.

According to the temperature we surveyed, the highest temperature in the three days from the 15th to the 18th in Yongan exceeded 38 degrees, which is the fastest year since records began to enter summer.

However, the eggs of flies will accelerate their development when the temperature is higher than 35 degrees Celsius, and they can develop into maggots within 12 hours.

The growth rate of maggots is very fast, at a rate of 0.2 cm per day. Of course, there are some rigorous formulas in it. After calculation, we finally got the result that the death of the deceased was about 2.8 days from the time we found it. "

A few younger policemen looked dazed, and their affection for Zhou Hai increased instantly. With a few words, they explained the obscure way of observation clearly.

"I went on to talk about the results of the autopsy. The wounds on the deceased were all cuts and cuts, totaling more than 80 cuts, and there were no fatal injuries.

During the autopsy, there was almost no blood in the heart, and the deceased died of systemic hemorrhagic shock.

Comparing the contents of the stomach of the deceased with the extracts from the glass found at the scene, we found two identical substances, one was methanol, and the other was an ingredient of the same type of sleeping pills.

The fingerprint of the deceased was found on the cup, and there was another fingerprint that was not identified. However, there was no blood or sleeping pills on the cup, so even if the owner of the fingerprint was found, it could not be concluded that it was the murderer.

On-site investigation found that the hands of the deceased were bound three layers.

The outermost layer is the power cord, and the innermost layer is a male threaded vest. The innermost layer has a trace of binding with a red glass silk rope, but the rope was broken, and the wrapped part also had cut wounds on the wrist.

On the wrist of the deceased, traces of a power cord binding were also found.

There were bloodstains on the soles of the feet, and there were traces of trampling, kicking and slipping with bare feet on the floor of the bedroom, and these traces were connected with pools of blood.

And a wavy slipper footprint spread all over the scene, from the bedroom to the living room, and then to the bathroom, back and forth many times, we deduce that this is the footprint left by the murderer.

Looking at the scars on the deceased's body, the scars on the upper torso and arms have obvious vertical columnar blood drops.

In other words, the deceased got up and moved after being injured.

As for the first red glass fiber rope on the wrist, it was broken at this time. The cross section of those glass fibers was very rough, and they were all silky and stretched a lot.

However, due to blood loss or sleeping pills, the deceased staggered and slipped.

While the murderer took advantage of his slipping or fainting, he shot him again and attacked the deceased for the second time. This time the deceased struggled and just climbed onto the bed without getting up again.

And the place where he fell down for the first time was at the end of the bed, where several large pools of blood appeared on the ground.

From the above analysis, it is not difficult to see that the murderer was obviously weaker than the deceased.

The deceased was taller and heavier than ordinary people, and he was also a cart driver. The murderer was very afraid, so he prepared wine, drugged, and tied up.

Moreover, the murderer was acquainted with the deceased, or very familiar.

Because the head of the deceased was covered with a towel, this is a manifestation of guilt, which is often seen in crimes committed by acquaintances.

As for the murder weapon, based on the shape and length of the wound, we judged it to be a right-angled blade without sharp corners, that is, a kitchen knife.

However, at the first scene, no murder weapon was found, and the murderer took it away.

This also shows that the murderer planned carefully and was fully prepared for the overall plan, and did not commit crimes of passion.

No information has been found on the ignorant fingerprint on the glass, but it can be used as evidence for investigation.

The vest has already been sent for extraction. As for the DNA test results, it will not come out until tomorrow morning!
My description of the suspect is:
Gender: Female;

age: adult;

Relationship with the deceased: acquaintance;

Time of committing the crime: the evening of May 5;

Mental state: Mature in thinking and stable in committing crimes.

There's only so much information I can analyze here, Team Lu! "

Lu Guangwen patted Zhou Hai's arm, motioned him to sit down quickly, and wrote down all Zhou Hai's analysis just now, and then looked at everyone.

"The characterization given by the forensic doctor Zhou has a clear goal. This analysis is well-founded. I agree very much. The next step of the work will mainly focus on investigating the social relationship of the deceased. If there is contact, there will be traces.

Xiao Pang led the team to continue to investigate the communication information of the deceased, and checked all the people who had called or exchanged information with the deceased within a month.

Da Wang'er followed to check the monitoring. On May 5th, all the women who entered and left the community after 15:[-] pm were screened, and all the suspects were taken screenshots. If there is a problem with the picture, we will find the information center to help restore the picture quality.

Daming took people to investigate the surrounding neighbors. Some things cannot be seen by surveillance, but the neighbors can get some information.

Xiaochun went to the bus station and took Bi Haitao directly back to the bureau to verify the time information in detail.

All suspects or objects that need to be investigated must leave fingerprint information to find the anonymous person.

Just before the meeting, I received a call from the leader of the bureau, asking us to solve the case within 48 hours.

The task is very difficult. At this time, no one should let me down the chain. I will bear the pressure. However, this case is related to the honor of our detachment. I hope you all weigh it carefully.

Well, stop talking nonsense, let's move! "
