The forensic wife is very nice to me

When I returned to the police station, it was already two o'clock in the afternoon. Qiu Lan hurried back to the office to get the autopsy report from the morning, and rushed to the meeting room.

Because so far, the forensics department and the forensic department have already made a preliminary determination of the oil drum murder case, so they need to pass all the information to the serious case team.

At 02:30 in the afternoon, the basic situation of the murder case was projected on the big screen in the conference room.

"The deceased Tan Yinsheng, aged 37, was from City A. He lived in Daming City, Dongcheng District, and worked as an accountant in a small business." Xu Chengyan pursed his lips lightly, with a serious expression. He turned on the infrared light and focused on each item. information.

"The circumstances of the murder case are all here. Because the situation of the garbage dump is complicated, we have not obtained any direct relevant evidence so far, so I hope everyone can help."

After finishing speaking, he glanced sideways at Qiu Lan who was sitting on the right, nodded slightly, and said in a calm tone, "Expert Cao, please project your identification results now."

"Yeah." Cao Fan stood up slowly, picked up a thin layer of documents in his hand, with a frosty expression on his face, "This time we brought back a total of [-] pieces from the garbage dump. potentially related items."

"We have inspected more than 400 cases yesterday and today, and have not found any new findings yet. Others are still being inspected, so let Dr. Qiu come first."

"Okay." Qiu Lan nodded, opened the document in her hand, and switched the projection on the screen.

She told everyone about the many problems and specific circumstances of the autopsy results in detail, and at the same time raised her own doubts and guesses.

"When I dissected the body, I found that the scars on the neck of the deceased were caused after death, so I suspect that the murderer may have a deep hatred for the deceased, or that another hater strangled the deceased after his death. broke his neck."

In the photos projected on the screen, there was a deep scar on the neck of the deceased. The wound had begun to rot, and the bones and muscles inside were clearly visible.

After seeing this photo, everyone at the meeting couldn't help but frowned, looking solemn.

Broken neck after death.

If it weren't for the deep hatred, it would definitely be impossible to be so cruel.

"One more thing." Qiu Lan pressed the controller in her hand and switched the content on the screen, "I found a mark on the chest of the corpse, which is very strange."

"This mark is a spotted red circle with a diameter of thirteen centimeters, and the ribs L3 and L4 corresponding to the skin are broken." She paused, her brows moved slightly, and a trace of doubt flashed in her eyes.

"I've thought about it for a long time, but I can't think of any necessary items that can cause such strength."

"Could it be caused by a racket?" Peipei frowned and asked doubtfully, "This shape and size are very similar to a table tennis racket."

"Impossible." Qiu Lan pursed her red lips, shook her head slightly, and denied Peipei's speculation without a moment's hesitation.

The subcutaneous rupture, the degree of tearing is equivalent to the impact force of throwing a person directly from the fourth floor.

A ping-pong racket was thrown from the fourth floor, and it had already been torn to pieces. How could it have formed such a regular shape, and she found no trace of sawdust on the corpse.

At the meeting, people from the forensics department and the serious crime team discussed for a long time, but they did not come up with a hypothetical possible answer.

Common items on the market are either out of shape or not strong enough to cause such a blow.

A circular scar became a mystery in the case.

However, the case of hiding corpses in oil barrels is not the only mystery that cannot be solved.

Qiu Lan opened the information in her hand, found a page, browsed it roughly, and remembered the content in her heart.

"Please read page 23 of the information in your hand. This is the phenomenon of corruption on the corpse." She lowered her eyes and said indifferently, her voice was cold.

"However, when we found the corpse, it was only three to four hours before the death of the deceased, and there was no rotten wound that would be formed three to five days later."

"According to the report of expert Cao, it is also confirmed." Qiu Lan frowned thoughtfully, analyzing all the cases in her mind and reorganizing the case.

"The oil barrel in which the body was found was filled with gasoline, and it was also filled with a concentration of [-] percent of Bill's hydroxyacid. This substance can keep heat, has a high strength and is corrosive, and can achieve the effect of disturbing our sight .”

"For example, it interferes with our judgment of the time of death, corrodes some small traces, for example, the skin flakes left by the murderer on the corpse."

Qiu Lan pursed her lips lightly, with a heavy expression on her face.

A strange oil barrel appeared in a waste disposal site with extremely complicated environmental conditions. The forensics department tested more than 400 items, but none of them were related.

And the strangeness of this case, if the staff hadn't discovered it by accident, the corpse might have disappeared without a trace.

The modus operandi is so meticulous, and the murderer also knows how to use a rare chemical to interfere with the police's sight.

This is definitely not a simple murder case, but a murder, a carefully planned murder.

And the murderer behind this must be a very terrifying person,
She has a hunch.

The atmosphere of the meeting reached zero in an instant.

This case seemed a bit tricky, and everyone present felt invisible pressure.

"One more thing." Henry put down the pen in his hand, stood up slowly, with sharp eyebrows, "The blood on the copper wire with green copper oxide we found at the scene is indeed not the deceased's, but it is the same as the deceased's." There is a blood relationship."

She switched the projected screen to the DNA comparison chart and spoke indifferently.

"There are fifteen pairs of DNA images that are the same, and the blood on the copper wire is XX chromosomes, that is to say, this is the deceased's biological mother or biological sister."

After hearing her words, the members of the serious crime team all looked at each other, and a trace of doubt flashed in their eyes.

"But." Xu Chengyan stood up, frowning, "According to the information we investigated, the deceased's mother passed away, and the younger sister also has an alibi."

Another mystery!
The meeting lasted less than 10 minutes, and the progress of the case was basically struggling.

Qiu Lan lowered her eyes, her eyes fluttered, and she kept thinking.

"Actually, it's not impossible at all." She raised her black eyes and looked at the people in the meeting room with heavy eyes, "Officer Xu, the appearance of the copper wire does not necessarily mean that the murderer killed, it may mean that the murderer has been there. "

In the phrase.

After hearing her words, all the people present nodded silently in agreement.

Xu Chengyan, who was caught in the mystery, suddenly became enlightened, his eyes flickered, "Doctor Qiu said, Zhigao, Xiaotiao, our next investigation direction should be in places where both the deceased and the deceased's sister may go."

Qiu Lan's words dragged the whole case out of the mud and brought it to a new direction.
