In the early morning of the next day, Lu Chuan hosted a case analysis meeting in the conference room No. 3 of the Interpol Brigade.
"I now introduce the fire situation at the scene."
After the fire broke out yesterday, when the preliminary judgment given by the firefighter side was the artificial arson, Chen Jiang rushed to the scene first, so the investigation of the starting point of the arson was relatively clear.
In addition, after Lu Chuan completed his assignment last night, Chen Jiang had another communication with the firefighters, sorted out the situation at the scene again, and conducted tests on some remaining burning materials. Determine the composition of the combustion aid.
"The fire started at the crime scene at the curtains on the balcony of the living room. We extracted some combustion accelerants from the residue of the curtains and determined that these combustion accelerants were gasoline. The suspect started at the crime scene from the balcony to the gasoline and extended to the living room. inside, but no gasoline was poured into the master bedroom, second bedroom, or kitchen.”
Chen Jiang opened the photos taken at the crime scene and explained them one by one.
"From the perspective of the entire fire point, the way to get angry was very violent, and the match should be ignited. We found two matches at the scene of the crime, but these matches have been burned, and only some are still left."
"The fire was basically burned in the living room, and then spread to the master bedroom and second bedroom bed, as well as the clothing in the wardrobe, and the quilt on the bed burning, but relatively speaking, the burning of the kitchen was weaker. The retaining is slightly more complete. "
You have to introduce the different situations of every burning room in the entire room while turning the projector.
Judging from the pictures, the burning situation in the living room was the worst. The sofa, TV coffee table, TV cabinet and a small cabinet in the living room were all burned to rubble.
"The suspect poured gasoline on all the furniture and appliances in the living room, and there should be gasoline residue on the deceased. The forensic doctor may give an introduction later, but I won't go into details here."
Lu Chuan looked at the forensic doctor.
After the corpse was pulled back to the Interpol Brigade last night, the forensic doctor began to dissect the body.
At more than eight o'clock this morning, the relevant autopsy report finally came out.
"After we pulled the corpse back yesterday, we first conducted a check on the surface of the corpse. It was found that some plastic melting products were left on the wrist and ankle of the corpse of the corpse last night. Things should be a lust belt, which means that the deceased should be limited to personal freedom before death. "
Forensic doctors took out a few comparison photos of some capitals and ankles on their wrists.
"At the same time, we also found some severe scars on the head of the deceased, which should be blunt. Therefore, the deceased should basically lose its ability to move before death."
"In addition, we have a large amount of ashes from the throat of the deceased and the lungs, which means that the cause of the direct death of the deceased was indeed burned to death. Although his head was attacked and the ability to move was basically lost, people still people still lost their ability to move. No death. "
“How is incapacity determined?”
Wang Zhaokai asked.
"That's right, we only found traces of ligatures on the deceased's ankles and wrists. But even so, the deceased could not stand completely, but the other party could still roll on the ground. If the suspect was released If there is a fire, then the other party is fully capable of rolling from the living room to the door or the kitchen, or other places where they can easily escape. However, when we found the body at the crime scene, it was basically burned to death where it fell to the ground. Traces of struggle.”
The photos on the projector can clearly show the deceased. The floor under the body is relatively complete and has not been burned. This means that the deceased basically stayed in place when he died and did not move much. .
“所以我们从法医解剖的角度来确定的话，死者在面临火灾的时候没有发生较大距离的移动，那就意味着对方不是不想跑，因为从一个正常人来讲，面对火灾的时候，只要He has the ability and will do his best to escape from the source of the fire. The other party does not move a large range of movement, that is to say, the other party is likely to be burned to death when he was in a semi -coma or lost his ability to move. >
"Do you find a weapon at the scene of the crime?"
Lu Chuan suddenly asked.
At this time, everyone turned their attention to the detective investigating the scene.
The other party quickly got up.
"Bureau Lu, we have discovered this."
Although the scene of the crime has been burned by a fire, and the reasons for fire spraying, the entire scene of the entire case has actually no large on -site survey value, but after Lu Chuan left, the on -site surveyer on the Interpol Brigade was still on the scene to the scene. A survey was conducted.
"We picked up an iron hammer next to the coffee table. There were some brown blood stains on it. Although it was not very clear after being smoked and burned, the test last night confirmed that it was indeed blood stains, and we have learned from the forensic department. It has also been confirmed that the injuries caused by this hammer are consistent with the injuries on the skull of the corpse.”
"However, we did not collect relevant fingerprint information and footprints at the scene of the incident. In this regard, the incident did not have relevant conditions, but we focused on checking the households."
There is no mistake in every song, one post, one content, one 6 one, one book, one book, take a look!
Survey the operation of the Criminal Police.
A close-up photo of the entry door appears.
"Because the inside of the department faces the living room, it has basically been burned. However, because the entrance door is made of flame-retardant material, the outside is relatively intact. We extracted the fingerprint information on the outside of the entrance door. Only one of the fingerprints was found, but the fingerprints did not belong to the suspect. His fingerprints were collected in the deceased's household registration information. We compared them and found that the fingerprints belonged to the deceased and not to anyone else. ”
"Another thing is that although the door lock of the door -to -door door has been burned from the inside, it has not been pried open outside. That is to say, the suspect entered the deceased's house. The door. "
"From this point of view, either the suspect disguised as a delivery or a person who cheated the owner to open the door, or the two parties knew it."
"How about the survey of interpersonal relationship between the dead?"
Lu Chuan looked at Wang Zhaokai.
This is one of the work arrangements he made yesterday. (End of chapter)
