Chapter 9 Trace Examination

The sun sets and the sun sets.

The old police dog Heizi, who had been running outside all day, dragged his tired body back to his kennel, quietly waiting for tonight's beef, chicken legs and vegetable risotto.

He is a meritorious dog with second-class merit. He has food subsidies and food subsidies jointly provided by the police and citizens. The average daily meal standard is 75 yuan, rain or shine.

Hou Lejia patted Heizi on the head and dragged his tired body back to the office of the Criminal Police Brigade. He boiled a pot of water, made a bowl of instant noodles, tore up a piece of ham, and ate it hungrily.

Halfway through the meal, the phone rang.

"Hello?" Hou Lejia frowned.

On the other end of the phone was a plain female voice: "Captain Hou? I'm at the fingerprint post of the Criminal Police Corps, and a fingerprint association from your county has found the results. I'll send you the details now, please accept it..."

Hou Lejia responded blankly, hung up the phone, and then quickly opened the police channel to read the content.

After just two glances, Hou Le's family dropped the instant noodles, stepped out in a few steps, and ordered people: "Lao Ping, order a few people and arrest them."

He has the habit of leading by example, both when he was a squadron leader and when he became a group leader.

Lao Ping, who was called, stuffed two mouthfuls of noodles into his mouth, called for the criminal police of his team to set off, grabbed his coat, and asked as he walked: "What case?"

"Last year's July 15th robbery. According to the co-investigation results reported back by the province, the person was at Tuoshan Forest Farm. He was a forest farm worker. There was a check-in record this morning." Hou Lejia said while walking: "The road over there is not easy to walk, so drive the pickup truck superior."

"Okay!" Lao Ping responded, and clicked his tongue twice: "This guy is playing tricks on us under the light. Is this forest farm a fingerprint of the Internet this year or something?"

Nowadays, many industrial and mining enterprises are required to install and network biometric identification systems, such as coal mines, and even to the extent of installing iris systems.

Hou Lejia shook his head: "The fingerprints have been online for a long time, and they were compared today. We will arrest the person first."

A few people ran downstairs in small steps. Lao Ping, who had been running all day, started the pickup truck. He took a breath and asked, "Would you like to take Heizi with you? Maybe we can use it when we go to the forest farm?"

The Hou Le family looked in the direction of the kennel. Heizi was chewing the chicken legs and was eating deliciously. He couldn't help but hesitated and said: "Forget it, Heizi is quite tired. Let him rest. Let's go and check the situation first."

Lao Ping rubbed his sore waist, smiled, turned the key and drove.

Pickup truck and run through the mountains.

People run for the hills.

Early morning.

It was already dawn, and the suspect signed the interrogation transcript.

The forestry workers in their twenties had little awareness of anti-reconnaissance, which they learned from movies and TV shows. The initial sense of luck dissipated, and the rest of the time they could only be led by the detectives.

The Hou Le family, who had been watching all night, breathed a sigh of relief, and finally felt a little optimistic in their tired mood.

Robbery is one of the eight major felonies stipulated in the criminal law, and the name of the so-called serious crime team comes from this. The police department has always attached great importance to such cases. In order to solve the case last year, the Hou Le family ran around day and night for several days, but no useful clues were found...

Being able to solve the case this time and successfully arrest the person is a great sense of accomplishment for Hou Lejia, the criminal police captain.

After thinking about it, Hou Lejia took out his mobile phone and called Huang Qiangmin from the Ningtai County Criminal Police Brigade next door.

The bell rings three times.

"Thank you, Captain Huang." Hou Lejia's voice was sincere.

Huang Qiangmin was a little stunned: "Did I offend you again?"

"No, to be honest, thank you sincerely." Hou Lejia's voice became more sincere. This is a thank you call, so don't get into the usual mutual hostility.

Huang Qiangmin chuckled: "Thank you for what?"

"You don't know?" Hou Lejia was stunned for a moment, and then he laughed inexplicably. After laughing, he told Huang Qiangmin about the results of the fingerprint analysis and the arrest of the person, and said: "Speaking of this case, It was also very close. The victim only called the police the next day, but it rained that night, so a lot of evidence could not be found. Of course, the suspect also relaxed his vigilance and thought we had forgotten about the case, ha..."

This time, it was Huang Qiangmin's turn to be silent.

After a few seconds, Huang Qiangmin slowly said: "So, you solved a robbery case?"

"Yes. I caught it with my own hands. Thank you for the trace inspection. I'll treat you to dinner when you have time." Hou Lejia ended the call with a smile.

Huang Qiangmin held his cell phone, put it back in his pocket, turned around and went up to the fourth floor where the Criminal Science Squadron was located.

He wanted to see how the trace inspectors, who were always complaining about it, hunted wild food.

Trace inspection room.

Yan Ge held a steaming teacup and drank hot tea while commenting on the fingerprints in front of him: "It's too blurry. There's paint on the leather. What do you think? They are collecting fingerprints now." …”

"Strict! Wang Zhong! You have become more capable!" Huang Qiangmin looked around, his eyes as sharp as a stray cat.

"Team Yellow." The two trace inspectors were shocked and stood up.

"You guys are too busy every day?" Huang Qiangmin's tone was stern.

A group of two trace inspectors panicked. What did we do that was inappropriate? We usually do this often, and we don’t get scolded...

The policemen of the Criminal Investigation Team, who conduct trace inspections all year round, have received less time from Huang Qiangmin's "military training", but precisely because of this, they are even less accustomed to Huang Qiangmin's severity.

"It's a good thing that the fingerprints matched, but I don't know if you should report to your superiors first? What about your organizational discipline?" Huang Qiangmin frowned, as fierce as if he was going to kill a rat.

Yan Ge and Wang Zhong were both confused and shook their heads.

Yan Ge whispered, "What fingerprints did we match?"

Huang Qiangmin was really confused this time. After thinking for a moment, he said, "Longli County solved a robbery case, a backlog case, and found the suspect through fingerprint matching. Lao Hou called to thank you. Didn't you two do it?"

"No." Lao Yan and Xiao Wang shook their heads again, a little difficult.

"Ask someone." Huang Qiangmin simply sat down.

He now felt like he had solved the case, and he was eager to get the result, or find a suitable path.

Yan Ge and Wang Zhong had to make their own phone calls.

Trace inspectors often have cooperative investigation tasks, and it is normal to ask questions.

After a while, the two hung up the phone and returned to Huang Qiangmin.

Huang Qiangmin looked at the eyes of the two and his expression became serious. The two looked so serious that Huang Qiangmin had to make a lot of associations.

"The news I received here." Lao Yan coughed twice, came to Huang Qiangmin, and his eyes unconsciously drifted to the position of the forensic office, saying: "The one who did the fingerprint comparison should be Xiao Jiang from our team. Jiang Yuan."

"Jiang Yuan... Which team?" Huang Qiangmin didn't know who he was for a while. He is the captain of the criminal police brigade. His subordinates include multiple criminal police squadrons, as well as police dog squadrons, criminal science squadrons, and anti-drug squadrons. There are hundreds of people and dogs in the team, and they are not sensitive to newcomers.

Xiao Wang said: "It's the new forensic doctor who is very tall."

"I know it when you say that." Huang Qiangmin matched the person with the name. It is true that he has more than a hundred criminal police under his command, but the forensic doctor is always one or two. On the other hand, Jiang Yuan's height is always impressive.

After talking about the person, the three fell silent again.

Yan Ge and Wang Zhong, who have been doing trace inspection for a long time, are confused. It is one thing to help other units to check fingerprints, and it is another thing to make fingerprints that other units cannot make.

In short, checking fingerprints does not necessarily mean that the fingerprints are difficult. It may also be that the fingerprint database of other units does not cover enough. Nowadays, there is actually no such thing as a national fingerprint database. Including each province, they only have a fingerprint database that covers a part of the fingerprints.

Therefore, most police officers who do trace inspections check fingerprints first check the criminal fingerprint database of their own city. If they cannot find it, they will check the vehicle management office or the database of identity information. If they still cannot find it, they will find the provincial department, send a joint investigation, and ask other units for help.

This kind of fingerprint that cannot be matched due to databases and other reasons is the fingerprint trace that Lao Yan and Xiao Zhao are familiar with. And they have rarely seen fingerprints that are matched by "brute force".

"Go and see it." Huang Qiangmin got up and walked out, and Lao Yan and Xiao Wang followed without hesitation.
