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

Chapter 241 Lock down the suspect

An hour later, Lu Chuan had arrived at the refrigerator.

"Xiao Lu, it's here, take a look."

There was a trace of excitement in Zhang Xiao's dignified face.

Just an hour ago, when Zhang Xiao was about to leave the refrigerator, he accidentally glanced at the supporting legs of the shelves against the wall.

On the side of the supporting leg, a brown scar was found.

The front of the scar is normal, but there are some marks on the back side next to the wall.

If you look at it from the front, you can't find this brown spot.

The reason why Zhang Xiao was able to find it was because his position was parallel to the shelf, and the angle of the light was just right, so he could find the scar at that position.

Then, Zhang Xiao checked it carefully, but in the end he was still not sure if it was the trace left by something he guessed.

So Zhang Xiao immediately called Xiankan.

Lu Chuan squatted next to the shelf, opened the inspection box, and took out the LSK fluorescent lamp.

When the lights were turned on, the floor, walls and shelves, which were originally colorless, were covered with traces of earthy brown.

"Blood!"

Zhang Xiao was just not sure just now, but now that there are large areas of earthy brown traces under the fluorescent light, he is finally sure that what he found is blood!
It's just that someone has cleaned up the bloodstains on purpose, so nothing can be seen on the surface.

However, the blood stains can be wiped off, but the hemoglobin in the blood is difficult to remove.

It is difficult to clean the protein substances in the blood with water. Even if it seems to be gone, there will actually be residues.

And this protein has a strong reflective effect on fluorescence, and it will emit earthy brown light under fluorescence irradiation.

Lu Chuanxia's research on the bloodstain is obviously much more in-depth than Zhang Xiao's.

Fluorescence can detect the presence of bloodstains, but it cannot prove whether the bloodstains are human blood.

Any trace of animal blood can emit fluorescent reflections.

"I'll take some residual substances and go back for analysis, and the results will be available in about half an hour."

Lu Chuan just heard Zhang Xiao mention that this cold storage room was leased by a fruit merchant.

It is usually used to store some fruits that are not easy to preserve.

If this is the case, then there should be no blood stains.

So, where did the bloodstains come from?

More importantly, the reason why Zhang Xiao checked these cold storages was that Lu Chuan found that the corpses might have been refrigerated.

"Okay, let's split up and report to Team Leader Ren right away. This Zhao Wenjun...see where he's going!"

Zhao Wenjun is the owner of the leased refrigerator, and only he has the key in his hand.

Moreover, this refrigerator is behind the freezer that Zhang Xiao inspected just now, and has a separate entrance and exit, which is relatively hidden.

Zhao Wenjun transported fruits in and out through his own truck, which was completely convenient for transporting corpses.

Criminal Investigation Detachment.

Qin Yong's office.

"found it?"

Ren Qiang nodded heavily: "I found it, a cold storage by the Bailan River."

"Zhang Xiao found traces of suspected blood inside. Lu Chuan went to the scene and found a large area of ​​blood that had been cleaned up with fluorescent lights."

"The bloodstain identification on Lu Chuan's side has just been completed, and it is confirmed to be human blood."

The blood of any mammal is red and contains hemoglobin.

Blood is red because hemoglobin is the physical carrier of blood that transports oxygen.

However, there are subtle differences in the composition of hemoglobin in different species.

The current survey can detect this difference through experiments. After comparing the standard ingredient list, it can be determined which animal left the blood stains.

"Are you sure the bloodstains belonged to the deceased?"

"It's not certain yet," Ren Qiang shook his head.

Lu Chuan has the ability to identify and analyze bloodstains, but it is impossible to determine the attribution from bloodstains that have no activity or have even been wiped off.

Moreover, due to the severe corruption of the rotting corpse, the blood in the body has long since disappeared, and it is impossible to extract effective marking information.

It is even more impossible to make a judicial comparison.

"However, I suggest that Zhao Wenjun be investigated now, and even summoned."

Qin Yong nodded.

A carrion corpse was found on the bank of the Bailan River. The corpse may have been refrigerated. A large amount of blood was found in the refrigerator rented by Zhao Wenjun.

These findings are connected, of course Zhao Wenjun may be the murderer.

"Moreover, when the manager of the cold storage called Zhao Wenjun and said that the police were going to check the cold storage, the other party did not respond for two or three breaths."

When making a phone call, Zhang Xiao asked the other party to use the hands-free conversation.

"The other party said it was because they entered the elevator and the signal was not good."

"But Zhang Xiaoming clearly heard the horn of a car on the phone."

"At first, Zhang Xiao didn't pay much attention to it, but after discovering the blood, Zhang Xiao thought that Zhao Wenjun must have been frightened at the time, so he hesitated and didn't speak immediately."

This is often the case when solving a case. There seems to be no abnormal behavior, but combined with some clues, it can be determined that there is a problem.

"Well, summon Zhao Wenjun immediately, and conduct a thorough investigation of his social relations!"

With the target person, the rest of the work is much easier.

In less than a day, all the information about Zhao Wenjun was presented to Qin Yong.

Zhao Wenjun, male, 38 years old, native of Haizhou City, has been doing fruit business.

"Zhao Wenjun started his business ten years ago, when durian production was reduced due to natural disasters, and the price was very expensive. Zhao Wenjun had a distant relative in Malay, who helped him order a large number of foreign durians. After they were shipped back to China, Zhao Wenjun earned the first barrel. gold."

"After that, Zhao Wenjun became a first-class fruit wholesaler in Haizhou City because of the large amount of funds in his hands."

"This is why Zhao Wenjun needs to rent a cold storage room to store precious fruits."

"Because of the fruit wholesale business, Zhao Wenjun's interpersonal relationship is relatively complicated, and he knows a lot of people, but after sorting out and checking, he found nothing abnormal."

Dozens of people under Ren Qiang's command were all mobilized to carefully investigate Zhao Wenjun's social relations.

However, no one is missing from relatives, friends, and the fruit wholesaler that Zhao Wenjun often cooperates with.

Qin Yong looked carefully at the report in his hand, frowning.

The results of the investigation about Zhao Wenjun were somewhat beyond Qin Yong's expectations. This person can be said to be very clean.

Although he has money, he has no bad habits, doesn't even smoke, and rarely drinks alcohol.

Not to mention gambling, this person usually doesn't even play poker, and his family relationship is relatively harmonious, so there is no trace of Zhao Wenjun having an affair.

"How about the interrogation room?"

Just two hours ago, Zhao Wenjun had been summoned from Tianzhou City to Haizhou City.

Qin Yong personally called the Tianzhou City Criminal Investigation Detachment, who sent someone to find Zhao Wenjun immediately.

Now, people are already waiting in the interrogation room.
