Chapter 276 Unexpected, How Could It Be...
An unexpected discovery?
Chen Yan was slightly startled and looked at Wang Meng: "What unexpected discovery?"
"It's a blood reaction!" The report Wang Meng handed over was a blood reaction to the murder weapon.
"We found two different blood reactions on sharp knives."
Gan!
"Different blood reactions?"
Chen Yan hurriedly took the report and began to read it.
The so-called two different blood reactions mean that the blood stains on the sharp knife belong to two people!
A blood reaction to the murder weapon is a routine examination.
The blood attachment will gradually weaken over time, but it will not disappear.
Especially the buried murder weapon, if it is not carefully cleaned with detergent before burial, after being buried in the soil, the murder weapon will be sealed to a certain extent, and while it is oxidizing, some blood components will also be preserved.
"Can you analyze the specific blood information?"
One of the blood information on the sharp knife at the crime scene was definitely that of Qiao Shouhe.
What about the other one?
Is it possible that he is the murderer?
Of course, even if not, then this person must be present.
This is a major clue to solving the case!
However, Chen Yan knew that although this blood reaction could detect two different types of blood, extracting specific information was not that easy.
Sure enough, Wang Meng shook his head: "We are already conducting further blood analysis."
“But now, it’s unlikely that complete information can be extracted.”
Not very likely...
"Try your best..."
After leaving the autopsy room, Chen Yan returned to the conference room.
The investigation of the case is now at the most critical stage.
If Wang Meng could extract detailed blood information, it would be possible to directly solve the case.
Without any further information, this lead is discontinued.
In front of the whiteboard, Chen Yan was deep in thought.
It has been confirmed that Qiao Shouhe was killed on the Tianqiao Road returning home.
So, why?
Who will kill him on the way?
Zhao Dongfeng?
It was unlikely. Since he had already ambushed Qiao Shouhe at the gate, there was no need to chase him down the field road.
What's more, it is impossible for Zhao Dongfeng to know Qiao Shouhe's whereabouts in such detail.
Is it possible that Zhao Dongfeng was actually waiting for Qiao Shouhe at the door of Qiao Shouhe's house.
Then he killed the person and buried him in the woods...
Is this possible?
Of course!
However, there is a problem here, and that is the first crime scene.
If Zhao Dongfeng really waited for Qiao Shouhe in front of Qiao Shouhe's house and killed Qiao Shouhe, then the first scene would be in front of Qiao Shouhe's house.
However, the investigators who were in charge of the traffic accident case five years ago went directly to Qiao Shouhe's house after receiving the video given by Zhao Dongfeng on the 5th.
No abnormalities were found.
In this regard, Chen Yan believed in the professionalism of the investigators at that time.
If Zhao Dongfeng killed someone in front of Qiao Shouhe's house, there would be no clues and no trace of blood would be left.
And it was impossible for Zhao Dongfeng to clean up the scene in the dark at night.
As for daytime on the 4th, it is even more impossible.
Qiao Shouhe's house was right on the roadside, with people coming and going, and Zhao Dongfeng had no time at all.
Another point, if it was Zhao Dongfeng who really killed someone, why would he hand over the video to the police?
After all, he didn't know that Fang Xiaohu had already watched the video.
Without this video, the traffic accident case would not have anything to do with Qiao Shouhe.
In this way, whether Qiao Shouhe died or not, there would be no suspicion of Zhao Dongfeng at all.
Therefore, it now seems that the possibility of Zhao Dongfeng being the murderer is indeed very small.
Of course, it is impossible to completely rule out suspicion, because if it was Zhao Dongfeng who spread the suspicion, it might be possible.
After knocking his head, Chen Yan still didn't have a clear idea.
Zhang Songlin and Zhang Runsheng had suspicions, but they had no motive.
Qiao Shanhe had a motive, because he might have been the driver at the time, but killing his son... was unlikely.
Qiao Shoushan had a motive, and Qiao Shoushan said that he was sleeping at home, but no one could prove it.
The last person was Zhao Dongfeng, who had both motives and actions, but he said he did not kill anyone.
It doesn't make sense logically.
Who is it?
boom!
The conference room door suddenly opened, interrupting Chen Yan's train of thought.
It's Wang Gang.
Although all the bones of Qiao Shouhe have been found, some pieces of clothes are still being discovered one after another.
Therefore, the excavation of the bushes has continued without stopping, and Wang Gang has been watching the scene.
"Team Chen, we made an unexpected discovery."
oh?
"What discovery?"
"Look at this!" Wang Gang handed over an evidence bag: "This is it."
Taking the evidence bag, Chen Yan observed it carefully.
"Is this... a ring?"
The outside of the object is covered with soil, but the occasionally exposed parts are golden yellow.
Wang Gang nodded: "This should be a ring."
"Moreover, the inner diameter of the ring is very small, and there is a raised part, so it should be a pattern..."
"A ring that a woman wears?"
"Yes!" Wang Gang nodded with excitement on his face: "It's a ring worn by women!"
"Let's go, send it to be cleaned and inspected immediately!"
Chen Yan's face also showed joy.
The discovery of the ring in a deep hole in the woods clearly cannot be a coincidence.
And it was a ring worn by a woman, so it couldn't be worn by Qiao Shouhe.
So, this ring is likely to belong to the murderer, or it was left by the murderer.
This is a major clue!
Identification team.
There is a detective who is responsible for cleaning up the evidence, and it is Song Lingxuan.
In the tray, Song Lingxuan gently clamped the ring with tweezers in her left hand, and slowly flushed it with a water pipe in her right hand.
But the flushing liquid is not water, but a special liquid.
The reason for such meticulousness is that it is unknown whether the ring covered by the mud is intact.
In addition, if the ring is worn on the hand for a long time, it is very likely to extract items or information such as dandruff and fingerprints.
Half an hour later, the ring was finally cleaned.
"The ring is intact, and there is a red line wrapped around it. It is very likely that the dandruff tissue of the ring owner can be extracted."
Song Lingxuan is not only good-looking, but also has good business skills.
Seeing the red line exposed, Chen Yan secretly breathed a sigh of relief.
The red line is wrapped around the ring because it is afraid that the ring will fall out of the hand.
Some people's fingers are so thick that no matter what number of rings they choose, they can't match them well.
The larger the number of circles, the looser it is; the smaller the number of circles, the tighter it is.
Therefore, many people can only buy rings with a large number of circles, and then wrap them with red thread, so that they can wear the rings firmly.
"Xiao Song is responsible for the test and extracting the residue in the red thread."
"Wang Gang," Chen Yan pointed to the ring: "Check the origin of this ring."
"Look at the pattern of this ring, the lines are clear, and there are hollow carvings. This is not a craft that a small workshop can do."
"It should be purchased through a formal channel. See if you can find the purchase information."
This clue is very important.
Chen Yan let out a long breath.
A gold ring worn by a woman...
Qiao Shouhe's death does not seem to be simple.
Could it be that the person who killed him was a woman?
However, among Chen Yan's current suspects, there is no woman.
"Captain Chen," shortly after Wang Gang left, Wang Meng received a message: "The blood analysis on the sharp knife has been completed."
"How is it? Have you extracted detailed information?"
If Wang Meng makes progress, the investigation of the case is likely to be completed immediately.
But Wang Meng shook his head: "Captain Chen, it's been too long. With current technology, there is no way to extract complete blood information."
"We tried our best, but we only determined the blood types of the two bloods on the sharp knife."
"One of them is AB type blood, which should belong to the deceased Qiao Shouhe."
"The other is O type blood."
O type blood?
Chen Yan frowned.
This is impossible!
How could it be O type blood?
Qiao Shanhe is A type blood, Qiao Shoushan is AB type blood.
Zhao Dongfeng is B type blood, and Zhang Songlin and Zhang Runsheng are also B type blood.
None of these suspects are O type blood.
What does this mean?
This means that the person who killed Qiao Shouhe may not be anyone that Chen Yan has suspected.
It is a person with O type blood who has never entered Chen Yan's suspicion.
Who is it!
Click!
A flash of lightning suddenly flashed through Chen Yan's mind.
A person's resume information suddenly appeared in front of Chen Yan, shocking Chen Yan.
"How is this possible?!"
