Chapter 275: Unexpectedly, how could it be...

Chapter 276 Unexpected, how could it be...

Accidental discovery?

Chen Yan was slightly startled and looked at Wang Meng: "What unexpected discovery?"

"It's a blood reaction!" The report that Wang Meng handed over was a blood reaction to the murder weapon.

"We found two distinct blood responses on the sharp knife."

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 on the sharp knife belongs to two people!

A blood reaction to the murder weapon is a routine inspection item.

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 burying, the murder weapon will be sealed to a certain extent after being buried in the soil, and some blood components will be preserved while it is oxidized.

"Can you analyze specific blood information?"

One of the blood information on the sharp knife at the crime scene is definitely Qiao Shouhe's.

What about the other?

Could it be the murderer?

Of course, even if not, then this person must be there.

This is a major clue to solve the case!

However, Chen Yan knows that although this kind of blood reaction can detect two different kinds of blood, it is not so easy to extract the specific information.

Sure enough, Wang Meng shook his head: "We are already conducting further blood analysis."

"But looking at it now, it's unlikely that the complete information can be extracted."

unlikely...

"Do your best..."

After leaving the autopsy room, Chen Yan returned to the conference room.

The detection of the case is now at the most critical stage.

If Wang Meng can extract detailed blood information, it is also possible to detect the case directly.

Without any further information, this thread is interrupted.

In front of the whiteboard, Chen Yan was thinking deeply.

Qiao Shouhe has confirmed that he was killed on the road back to his home.

So why?

Who will kill him on the way?

Zhao Dongfeng?

It is unlikely that since he has already been ambushed at the gate of Qiao Shouhe's house, there is no need to hunt him down on the ridge 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 at the door of Qiao Shouhe's house, but he had already waited for Qiao Shouhe.

Then after killing people, they buried them in the dwarf forest...

Is this possible?

Of course there is!

However, there is a problem here, and that is the first crime scene.

If Zhao Dongfeng really waited for Qiao Shouhe at the gate of Qiao Shouhe's house, and killed Qiao Shouhe, then the gate of Qiao Shouhe's house would be the first scene.

However, the investigator who was in charge of the traffic accident five years ago went directly to Qiao Shouhe's house after getting the video given by Zhao Dongfeng on the 5th.

No anomalies were found.

On this point, Chen Yan believed in the professionalism of the case investigators back then.

If Zhao Dongfeng murdered at the door of Qiao Shouhe's house, there would be no clue, and there would be no trace of blood.

And at night, Zhao Dongfeng couldn't clean up the scene in the dark.

As for the day on the 4th, it is even more impossible.

Qiao Shouhe's house was on the side of the road, people came and went, Zhao Dongfeng didn't have time at all.

Another point, if Zhao Dongfeng really killed someone, why did he hand over the video to the police?

After all, he didn't know that Fang Xiaohu had seen the video.

Without this video, the traffic accident and Qiao Shouhe would not have anything to do with it.

In this way, Qiao Shouhe will not die, and he will not suspect Zhao Dongfeng at all.

Therefore, it now seems that the possibility that Zhao Dongfeng is the murderer is indeed very small.

Of course, it is impossible to completely rule out the suspicion, because if it was Zhao Dongfeng who made the suspicion, it might be.

After knocking on his head, Chen Yan still didn't have a clear idea.

Zhang Songlin and Zhang Runsheng had doubts, but they had no motivation.

Qiao Shanhe had a motive, because it was possible that the person driving the car at that time was him, but killing his own son...it was unlikely.

Qiao Shoushan had a motive, and Qiao Shoushan said that he was sleeping at home, but no one proved it.

The last person was Zhao Dongfeng, who had both motives and actions, but he said that he did not kill anyone.

Logically it doesn't make sense either.

Who is it?

boom!

The door of the conference room suddenly opened, breaking Chen Yan's train of thought.

It is 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 dwarf forest has been going on without stopping, and Wang Gang has been staring at the scene.

"Chen team, there is an unexpected discovery."

Oh?

"What did you find?"

"Look at this!" Wang Gang handed over an evidence bag: "It's this thing,"

Taking over the evidence bag, Chen Yan observed it carefully.

"This is... a ring?"

The outside of the item is covered with mud, but 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 are raised parts, because it is a decoration..."

"A ring worn by a woman?"

"Yes!" Wang Gang nodded, excited: "It's the ring worn by women!"

"Go, send it to clean up immediately!"

Chen Yan's face also showed joy.

The discovery of the ring in a deep pit in the dwarf forest clearly cannot be a coincidence.

And it's a ring worn by a woman, so it can't be worn by Qiao Shouhe.

So, is this ring likely to belong to the murderer, or is it left behind by the murderer?

This is a big clue!

identification group.

The detective who was responsible for clearing the evidence was Song Lingxuan.

In the tray, Song Lingxuan lightly clamped the ring with tweezers in her left hand, while a water tube in her right hand was slowly rinsing.

But the flushing liquid is not water, but a special liquid.

The reason why it is so detailed is because it is not known whether the ring under the mud cover is in good condition.

Also, if the ring is worn on the hand for a long time, it is very likely to extract items or information such as dander and fingerprints.

After half an hour, the ring was finally cleaned up.

"The ring is intact, with red threads wrapped around it, and it is very likely that the dander tissue of the ring owner has been extracted."

Song Lingxuan is not only good-looking, but also has good business skills.

Seeing that the red line was exposed, Chen Yan secretly breathed a sigh of relief.

The red thread is wrapped around the ring because I am afraid that the ring will fall off my hands.

Some people's finger thickness, no matter what kind of ring they choose, they can't match well.

Larger turns are loose, smaller turns are tight.

Therefore, many people can only buy rings with a large number of laps, and then wrap them around the red thread, so that they can wear the ring firmly.

"Xiao Song is in charge of testing and extracting the residues in the red line."

"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 regular channels, and 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 did 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.

"Team Chen," shortly after Wang Gang left, news came from Wang Meng: "The analysis of the blood on the sharp knife has been completed."

"How is it? Has the detailed information been extracted?"

If there is progress on Wang Meng's side, then the investigation of the case is likely to be completed immediately.

But Wang Meng shook his head: "Team Chen, it's been too long. With the current technical means, there is no way to extract the complete blood study information."

"We tried our best to determine the blood types of the two types of blood on the knife."

"One of them is blood type AB, because it belongs to the deceased Qiao Shouhe."

"The other is blood type O."

Type O blood?

Chen Yan frowned deeply.

This is impossible!

How could it be blood type O?

Qiao Shanhe has blood type AQiao Shoushan has type AB blood.

Zhao Dongfeng has type B blood, while Zhang Songlin and Zhang Runsheng are also type B blood.

These suspects are not type O blood.

What does this represent?

This meant that the person who killed Qiao Shouhe might not be anyone Chen Yan had already suspected.

It is a person with type O blood who has never entered Chen Yan's line of suspicion.

Who is it!

Click!

Suddenly, a flash of lightning flashed across Chen Yan's mind.

A person's resume information suddenly appeared in front of Chen Yan, and Chen Yan was stunned.

"how can that be?!"
