Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 338 Autopsy Results Report
Qin Yong sighed: "Let's do the basic work first, the visits must continue, and the identity of the deceased should be determined as soon as possible."

This is not a formal occasion, and Qin Yong just wanted to get an overview of the situation.

After a brief report, Liu Guodong grabbed Ren Qiang.

"Old Ren, you just said that the deceased sometimes went to work with his colleagues and rode an electric car?"

Ren Qiang nodded: "It's only three kilometers away from the cotton factory. This couple usually rides electric bikes to work."

Riding an electric bike to work?

This detail attracted Liu Guodong's attention.

There are not many clues found at the scene. A sharp knife with a scorched handle, and no burnt tire marks on the ground after the closet fell.

It now appears that this tire mark is the electric car that the deceased usually rode to work.

But no remains of the electric car were found in the house.

So, where did this electric car go?

Liu Guodong reported to Qin Yong immediately.

"Electric car?"

"You mean, the murderer left on a scooter?"

"It's possible, otherwise, where would the electric car go?"

Lu Chuan is still doing surveys.

Since the tire marks found in the house belonged to the deceased's electric car, the most likely reason for the electric car disappearing is that it was ridden away by the murderer.

What Lu Chuan is doing now is to check whether the tire marks of electric vehicles can be found outside the fire scene.

The tire marks of the electric vehicle in the house should have been left when the vehicle was empty.

But the traces outside may be the traces left by the murderer riding an electric car.

In this way, by comparing the two traces, Lu Chuan can analyze the approximate weight of the person riding the electric bike.

On the other hand, the murderer's fingerprints and shoe prints in the room have now been destroyed by the fire and fire sprinklers, and nothing has been found.

But what about the other party's traces outside?
Half an hour ago, Lu Chuan was asked to look for it, but he still had nothing to do.

After all, after the incident, the scene was on fire, too many people arrived at the scene, and the ground was full of messy footprints. No one knew if there was a murderer here.

Or even if there was, which one belonged to the murderer?

Well now, with the inference that the murderer left by riding an electric car, it is possible to find the murderer's footprints based on the spatial distance of the electric car's tire prints.

04:30 in the afternoon.

Criminal investigation detachment meeting room.

Wang Changjiang began to report the results of the autopsy.

Two corpses, the female corpse on the bed is marked as No. [-], and the male corpse on the ground is marked as No. [-].

"Corpse No. [-], a female, had a wound stabbed in the chest with a sharp object, right in the middle of the heart. There were no obvious traces of smoke and carbon deposits in the throat, respiratory tract, and nasal cavity of the deceased. The color of the internal organs was normal. It can be judged that before the fire, the victim The signs of life have been lost."

"In addition, there were knife wounds on the abdomen, back waist and other parts of the corpse, three of which were wounds before death, and six of which were wounds after death."

"Although the lower body has been scorched by the fire, according to the anatomical examination, it should not have been violated."

Wang Changjiang reported in detail the situation of No. [-] corpse.

"There was no violation, but there were postmortem stab wounds on the body. Were they at the fatal parts?"

Ren Qiang grasped the most important point.

Under normal circumstances, there are two situations in which the murderer still uses the knife after the deceased dies.

One is to make up for fear that the opponent is not dead.

The other is retaliatory killings, where one stabbing does not relieve one's anger, and one continues to slash a few more times.

These two situations also have their own characteristics.

In most cases, the location of the supplement knife is more important on the body, such as the abdomen, chest, neck and other parts.

Because the purpose of making up the knife is to kill the opponent completely and ensure the success of the kill, so all the people rushing are the vital parts, and the main way of injury is stabbing.

The post-mortem injuries of venting anger and retaliation are mostly slashing and slashing. The main way of using a knife is to slash with a knife, which is more common on the limbs, face, and chest.

"Not in fatal parts, no burnt parts of extremities, postmortem wounds on abdomen and face."

Wang Changjiang looked around and saw that everyone was frowning. Knowing that no one asked any more questions about the situation of the No. [-] corpse, he continued to report.

"Next is corpse number two."

Wang Changjiang switched the projection, and what appeared was an overhead photo of No. [-] corpse at the scene.

"When the No. [-] body was discovered, it was in a state of lying on the ground, and its limbs were in a crawling motion. Here..."

Wang Changjiang pointed to the ground in the photo: "We have checked carefully over there, and there are traces of digging and blood on the ground."

"Although the hands of Corpse No. [-] have been charred and carbonized, the traces have not completely disappeared."

"In addition, corpse No. [-] showed carbon and oxygen saturation, and obvious red spots appeared on the unburned parts of the corpse. The characteristics of carbon monoxide poisoning were obvious."

"In addition, we found obvious smoke burn marks and carbon dust deposits in the respiratory tract of the corpse."

In fact, generally speaking, the corpses that died in the fire will inhale high-temperature gas during the breathing process, and the entire respiratory mucosa will be red, swollen and congested.

In severe cases, it may even completely block the airway, causing oppressive suffocation.

However, the throat area of ​​Corpse No. [-] was exposed while lying on its stomach. Most of it had been burnt and carbonized, and no redness or swelling could be detected.

Wang Changjiang still found redness and swelling in the nasal cavity and bronchi.

Autopsy identification does not mean that a unique conclusion can be drawn after seeing the traits of a certain part of the corpse.

It is also necessary to combine the anatomical results of other parts to make a comprehensive judgment.

For example, if you die from suffocation in a fire, you need to look at the condition of your lungs and organs, as well as check for dissolved substances in the stomach, and then combine with the body surface and environment before you can finally make a conclusion.

Seven years ago, the forensic doctor of QZ City was criticized by the whole province because of the wrong judgment of the autopsy.

The deceased first died of carbon monoxide poisoning, then was carried away, and the body was set on fire.

During the forensic examination, they ignored the results of the respiratory examination and focused on the carbon-oxygen saturation reaction, and concluded that the body was burned to death.

Later, the murderer brought the case out because of other things, and the truth came out.

Therefore, Wang Changjiang was more careful during the autopsy of the burned corpse.

Only when every anatomical result is consistent can a conclusion be drawn.

"In addition, corpse No. [-] has obvious stab wounds on the abdomen. The shape of the wounds is the same as the stab wounds on corpse No. [-]. It should be the same murder weapon."

"Is the No. [-] corpse injured by chopping?"

Ren Qiang asked again.

"No, the No. [-] body only had stab wounds on the abdomen, and no stab wounds were found in other parts."

After Ren Qiang confirmed, he shook his head, indicating that he was fine.

Qin Yong looked at Wang Changjiang, who nodded, meaning that his report was over.

"Okay, let's talk about your views."
