Chapter 463 Strange Fingerprints
On the day of the 100th blind date, arrest the blind date Chapter 463 Unfamiliar fingerprints
Regarding the background investigation materials of Han Long and Qin Lu, Zhang Chaoyang did a more detailed one.
Han Long didn't have any enemies in Yinglu City, and the foreign trade companies he opened were all completed with the support of his former father-in-law, Qin Jun, and from what he knew so far, Han Long was a well-rounded person, very smart, and never got along with him. People blush, let alone any enemies.
In fact, not only did Han Long have no enemies, he even had few real friends in Yinglu City.
After all, Han Long had only been in Yinglu City for five years, and except for Qin Lu's family, he knew people from foreign trade companies.
Qin Lu...
Sitting in the office, Chen Yan was thinking carefully about every detail during the interrogation of Qin Lu.
During the interrogation, Qin Lu's impression on Chen Yan was completely different from Zhang Chaoyang's investigation.
When they were studying at the police academy, Chen Yan's teacher had taught them that they should never bring their personal feelings and subjective assumptions into account when dealing with cases.
All reasoning and speculation must be based on the clues that have been discovered.
At that time, no one understood why the teacher said that.
It wasn't until Chen Yan had handled more than 30 cases that he understood the true meaning of the teacher's teachings.
The logic of investigating any case is very important, but not the most important.
Because many eucalyptus in reality do not follow logic.
Every murderer has a variety of reasons for killing.
Everyone also has multiple sides, not as good as Qin Lu.
When Chen Yan first saw Qin Lu in a wheelchair with disabled legs in the interrogation room, he would naturally put her on the weak side in his heart.
In fact, Qin Lu took advantage of this and concealed some facts during the interrogation.
Like how her legs were broken.
For example, how she treated Han Long after marriage.
As a result, after the entire interrogation ended, Han Long was labeled as ungrateful.
When a wage earner had nothing, he fell in love with the daughter of his company boss.
Then after a successful career, he ruthlessly abandoned his wife with disabled legs.
Turn your head and live happily with your childhood sweetheart.
But in fact, Qin Lu's disabled legs were caused by jealousy with other women.
After she married Han Long, she was still fooling around outside.
He even beat and scolded Han Long frequently.
The reason for the divorce of the two is not on one side.
Dong Dong Dong.
The knock on the door interrupted Chen Yan's thinking: Please come in.
It was Liu Qingshan: Chen Yan, we have almost checked the clues of the delivery staff and the restaurant.
oh?
Let's go to the conference room.
Liu Qingshan began to report the results of the investigation.
Through the support provided by the food delivery platform, we found all the food delivery orders from Hanlong's mobile phone account.
On the projection screen is a compiled summary cousin: Han Long started using this mobile phone account five years ago, and the first takeaway order was three and a half years ago.
Everyone, please take a look, this is all the orders of braised lion heads that Han Long has ordered.
The form on the screen has a total of 46 order numbers.
Since Han Long used this mobile phone number to order takeout, he has ordered 46 braised lion heads in total.
The first order for braised lion head was four years ago on September 28.
Han Long placed the first ten orders at different restaurants.
However, from the sixth to the last Lion's Head takeaway, Han Long's orders are all from Hongyun Sichuan Restaurant.
On the projection is a photo of the entrance of Hongyun Sichuan Restaurant.
Judging from the number of takeaway orders, Han Long himself should prefer to eat braised lion heads.
Besides, after the sixth takeaway order, the lion head takeaway ordered by Han Long was all from Hongyun Sichuan Restaurant, which means that after Han Long ate the braised lion head from this Sichuan restaurant, he should think it was more delicious, so the later orders The takeaways are all from this Sichuan restaurant.”
Let's look at the time distribution of Han Long ordering this takeaway.
Forty-six braised lion heads, the average time interval of the first 26 servings is once a month.
However, the takeaway order started at 11:28pm on May 1st, and the frequency of ordering food delivery has become almost three days.
And this time should be relatively close to the time when the deceased was killed, so we conducted a detailed investigation on the 20 takeaways after the evening of May 1.
The food delivery staff were all dispatched by the system immediately, and a total of 14 people took the food delivery order.
The deliveryman with the most has taken three orders.
The main basis for dispatching orders on food delivery platforms is distance.
Within the effective distance, the platform will give priority to dispatching the order to the delivery person closest to the seller's location.
Then wait for the other party to take the order.
If the delivery person is free, confirm the order, and the ordering process of the order at the delivery person is over.
As for the seller, there is another ordering process. When the buyer places the order, the seller will receive a notification from the system and just make it directly, and the delivery staff will come to pick up the meal.
The service of the delivery staff has a certain range, probably one or two blocks, and some delivery staff will stay near the popular restaurant street, or at the door of a certain store, waiting for the takeaway order from this store.
So there will be situations where someone sends orders continuously.
Except for one of the 14 people who left the job last week, we have not been contacted now, and the others have been contacted one after another.
There is also the owner of Hongyun Sichuan Restaurant, who has also been subpoenaed.
What is the specific result?
Based on the situation of the video investigation, Lan Feng had roughly reported the relevant situation to Chen Yan, but it was not as detailed as Liu Qingshan.
We have completed fingerprint information collection and compared the 36 packing boxes found on Han Long's dining table.
The result...is a bit strange.
Um?
Have you found any problems?
Liu Qingshan nodded: There are indeed some problems.
The first is the shape of the takeaway box.
The 36 packing boxes on Han Long's dining table, 20 of which are from Hongyun Sichuan Restaurant, with the logo of Hongyun Sichuan Restaurant on it.
The other 16 have no logo on them, and it is in these 16 unmarked packaging boxes that we detected Zhang Yao's tissue DNA information.
However, the appearance of these 36 boxes is exactly the same, the difference lies in the logo of Hongyun Sichuan Restaurant.
That means the boxes are all of the same type.
I sent someone to the market to see that there are many types of packing boxes on the market.
Is it a bit of a coincidence that the packaging box used by the murderer is exactly the same as that of Hongyun Sichuan Restaurant?
Also, among the fingerprints we extracted on the packaging box, the fingerprints on the packaging box from Hongyun Sichuan Restaurant can be matched with the delivery staff and restaurant packaging staff.
However, we also found another type of fingerprint.
It's on all the take-out boxes, but it can't match the packers, takeaway staff, etc. of Sichuan cuisine restaurants.
Apricot
Can't match?
Chen Yan frowned slightly looking at the fingerprints on the screen.
Is it possible that it was left by the murderer?
Hu Xueying guessed.
Chen Yan shook his head: This possibility is relatively small.
The murderer was very cautious during the whole process and did not leave any clues at Han Long's home.
Leaving your own fingerprints on the packing box...the murderer would not make such a low-level mistake.
Well, Qingshan, check the source of these packing boxes.
During the use of the packaging box, in addition to contacting the delivery staff and the packaging staff of Hongyun Sichuan Restaurant, it may also be touched by people during the production or transportation process.
Look up, where did Hongyun Sichuan Restaurant get these packed boxes.
Also, collect the fingerprint information of all the personnel in the Sichuan restaurant for comparison!
yes!
This is an important clue.
As Liu Qingshan analyzed at the beginning, there are many types of packing boxes on the market. Why is the shape of the packing box used by the murderer the same as that used by Hongyun Sichuan Restaurant?
Is it a coincidence or is there another reason?
Moreover, there was only one unfamiliar fingerprint collected on the packing box.
What does this mean?
This shows that if this fingerprint is not left by the murderer, it can also prove one thing.
The packing box used by the murderer is not only exactly the same as the packing box used by Hongyun Sichuan Restaurant, but it is also very likely to be purchased from the same channel!
***************
How about the investigation of the origin of the large grain of salt?
After killing Han Long, the murderer removed all his flesh and blood, and then pickled it in a jar with large grains of salt.
This is a good way to deal with the smell of decaying corpses.
It is also the most important reason why the neighbors did not find the abnormality.
But Liu Qingshan shook his head: The investigation in this area is progressing very slowly.
We surveyed several large supermarkets in Yinglu City, and each of them sold this kind of large-grain salt.
Although there are not many people buying in this season, there are more sales outside of large supermarkets and in some small supermarkets in the urban-rural fringe.
In large supermarkets, we can find the sales of large grains of salt based on the sales records, but in small supermarkets in the urban-rural fringe, there is no way to check at all.
Where's the wax?
The murderer sealed Han Long's head with wax to prevent it from being corrupted. There should be relatively few sales of such things. Have you found out the source of the sales?
There are some clues in this regard.
It turned out that although the oil wax used by the murderer was rather special, it was very common in Yinglu City.
The oil wax used by the murderer is a material used to make oil wax toys.
On the screen was a photo of a wax-sealed sand table.
So it's this thing, I've seen it before!
When Hu Xueying saw the photos played by Liu Qingshan, she suddenly said, There are toy stalls like this in shopping malls or by the side of the road.
It's an oil wax toy that children play with.
Yes, it's this kind of thing. I have also played with children.
It turned out to be this kind of thing. I took my children to play with it on the side of the road last week.
Many detectives from the Yinglu City Criminal Police Team agreed.
It turned out that this is a toy solidified oil wax.
Generally, put some sea sand and some small dolls in the glass bottle, and then seal it with this kind of oily wax with high transparency.
Immediately, it is like freezing in transparent water, which is good for viewing and easy to operate.
Children can operate it by themselves, and the temperature of the oil wax is not high, so there is no need to worry about burns.
We checked and found that this kind of low-temperature oil wax with high transparency can be purchased in several wholesale markets in Yinglu City.
There are a lot of people who buy it, and the sales volume is relatively large, so it is more difficult to track down.
Large grains of salt, oily wax...
These two leads are basically broken.
Now, there is only one clue left, which is the strange fingerprint.
After it was over, Chen Yan came to the monitoring room.
In the monitoring room, Lan Feng is interrogating the owner of Hongyun Sichuan Restaurant.
Han Long?
I don't know you. There are hundreds of people eating in our restaurant every day. I can't recognize them all.
The owner of Hongyun Sichuan Restaurant is Zhang Xu, a native of Sichuan Province, who has been in Yinglu City for ten years.
In the early years, I set up a street stall in Yinglu City. Because I cooked good dishes, it gradually became bigger. After I made some money, I opened Hongyun Sichuan Restaurant.
The business in the past few years has been good, and I have made a lot of money. I bought a house in Yinglu City and settled down.
Since Zhang Xu had no impression of the name Han Long, Lan Feng took out Han Long's photo.
This is the person, do you have any impression?
Before Zhang Xu took the photo, the expression on his face suddenly realized: You say this person, I have an impression of this person.
This person is a regular customer of our restaurant and often eats at our restaurant, but we are also nodding acquaintances. I didn't know his name was Han Long.
Judging from his accent, he is also from Sichuan Province. It seems that he came here to do business. The business should be doing well. I think he drives a good car. He used to come here basically every week, but these two days It seems that the month has not come, and I haven't seen him for a while.
Is there something wrong with him?
Let me tell you, comrade policeman, I really don't know him, he just often eats at my restaurant, but I really haven't seen him in the past two months.
Is he familiar with anyone in your hotel?
familiar?
Zhang Xu shook his head: He came here from Sichuan Province to do business. It must be better to be a mess. If you want to eat home food, you just nod to us. You definitely don't know our people.
Oh, by the way, when he used to come here, he often brought a woman with him.
Lan Feng took out Zhang Yao's photo: Is it this person?
That's right, that's the woman.
Are you sure no one in your hotel knows this Han Long?
Definitely not. If there is, I will definitely give him a discount.
Is there anything unusual about your hotel staff recently?
There is nothing unusual about us. Those who run restaurants earn hard money, and they get up early and return late.
The people who work in my restaurant are all from my hometown. The longest one has been working for three years, and the shortest one has been more than one year. They are all familiar people who know the basics.
Except for a while ago, I fired a helper named Wang Hongfei in our store, and everyone else is working here very steadily.
Fired?
Well, he also came from Sichuan Province to work, but it was introduced by others. He worked at my place for three months. I thought this kid was quite down-to-earth, but it turns out that his hands and feet are not clean.
I stole a lot of things in the back kitchen. About three months ago, I found out. I thought he was a fellow, so I didn't call the police, and then fired him.
In addition to the manager of the Hongyun Sichuan restaurant, Lan Feng interrogated the waiters and chefs of the Sichuan restaurant one after another, and the information provided by Zhang Xu was not different.
Han Long had acquaintances with Sichuan restaurants during his lifetime, but only for eating.
But the murderer obviously knew that Han Long liked to eat the braised lion head from this Sichuan restaurant.
So what does this person have in common with Han Long?
There is also Zhang Yao who has been killed with a high probability.
So far only some flesh and blood tissues of Zhang Yao have been found, but no skeleton or other parts of the body have been found.
Also, all the things that Zhang Yao used in Han Long's house disappeared. Why did the murderer do this?
Walking out of the monitoring room, Chen Yan called Li Hong directly.
Han Long was killed, Zhang Yao was killed, and all Zhang Yao's belongings in Han Long's house disappeared. There must be a very important connection here.
Chen Yan decided to investigate from the root cause.
For example, when Zhang Yao ran away from home, it was because her parents were in charge of her marriage.
So why did Zhang Yao not agree to the marriage her parents had arranged for her?
Also, Zhang Yao went straight to Yinglu City to join Han Long after leaving home.
Did the two have a close relationship when they were in the village?
Otherwise, why did Zhang Yao come to join Han Long?
What is the relationship between them.
And Han Long's ex-wife Qin Lu, when she was interrogated by Chen Yan, she deliberately concealed the information, just to preserve her image in front of outsiders?
Is there any other purpose.
Judging from the results of Zhang Chaoyang's investigation, Qin Lu is not a fuel-efficient lamp.
In the end, she allowed Han Long to cheat and then simply divorced?
Something is wrong!
There must be some secrets here that Chen Yan and others haven't discovered yet.
Li Hong put down Chen Yan's phone number and sent a letter of assistance to the Sichuan Provincial Criminal Police Department.
In fact, this thing can also be issued by the Yinglu City Police Department.
However, Yinglu City can only issue a joint investigation letter to the municipal detective team where Han Long's hometown is located, and because it is inter-provincial, on the one hand, it needs approval from the Liao Provincial Criminal Police Brigade, and the letter can only be sent after approval.
After receiving it, they also asked the Sichuan Provincial Criminal Investigation Brigade for instructions, and only after they agreed could the assisted investigation work begin.
In this way, there is no two or three days that can't be done at all.
Sending this letter through Li Hong is different.
The Sichuan Provincial Criminal Investigation Brigade will receive the letter immediately, and then directly forward it to the local criminal investigation team in Han Long's hometown. The investigation results will be reported as soon as tomorrow.
