After asking Zhang Xiaoyuan, he asked Ma Hui, and after asking Ma Hui, he asked Sun Dongxue...

Sha Haijian asked in Dongguang, and Su Haibing and other task force police officers in other places were asked in other places. They kept understanding and verifying each other, and further investigations were made from 21 women who had worked in the seafarers club that year to 67 men who had more or less related to them.

The word "investigation" sounds simple, but not so easy to do.

12.26 In the past eleven years of the case, a lot of evidence has disappeared over time. We cannot act rashly and cannot rashly contact those who are to be investigated.

To avoid alerting the enemy, we first understand where they were before and after the incident and whether there is time for the crime. After that, we will find various excuses to collect their fingerprints and even DNA for comparison.

This excuse is not difficult to find. Yesterday, a theft or a hit-and-run accident occurred in your unit or near your home. It is the obligation of every citizen to cooperate with the public security organs to handle the case. Find out some situation, make a record, and fingerprints. As for biological examination materials, those who smoke, pick up a few cigarette butts, and those who don’t smoke will think of other ways, such as helping you pull your hair white, etc.

There is no way to go, so I can only collect their parents' biological samples and the cells on the dagger for paternity tests. How much does it cost to travel on a trip? It only costs 200 yuan to build a DNA sample, which is easy to calculate.

The person who was going to collect samples today was special. My father died early, my mother lived at my sister's house in Donghai, and he himself was doing business in Zhangwan City, Jiangnan. If he hadn't found a relative of his 80th birthday, it would have been difficult to find him.

Can I drink birthday wine? Can I drink wine by driving?

Xiao Xu changed into a traffic police uniform, stopped him with the traffic police, signaled him to stop the fire, and saluted: "I am Qin Ming, a policeman of the Second Traffic Police Brigade, please show your driver's license."

Tan Haichao thought it was really unlucky. If he had known that the traffic police would check the car, he would go to the ferry from another road, take out the driver's license from the back of the sun visor, and take out a cigarette and say in a flattering manner: "Train Police Comrade, I have a certificate, I have a certificate, I have a certificate, I have a certificate, I have a certificate, I have taken the exam in my hometown, and I have a foreign license plate when doing business outside. This is not a foreign car, I am not a foreigner."

"Can local people violate the rules if they are local cars?" Qin Ming asked back and opened his ID to check the authenticity.

After drinking, my face turned red and my ears were red. The next work was ready. Xiao Xu took out the alcohol tester that he had prepared early: "Get out of the car first, get down and blow it."

"Comrade policeman, there is no need to blow. I didn't drink much. I'm not from outside, please help." Tan Haichao hurriedly fetched out a few boxes of cigarettes from the car, and stuffed them into their pockets regardless of the severity.

"Don't do this, put away the cigarette."

Xiao Xu's face turned up and he reached into the car to pull out the key: "I smelled alcohol all over my body, and I knew I had drunk a lot. I can't drive like this. Get in our car and go to the squadron first."

"Comrade Police, I have something to do or urgent matters. I can accept the penalty, and I can give it a ticket."

What a joke?

In order to find out your whereabouts, I ran and broke my legs in the past few days. I finally found an opportunity to stop you. Don’t say that you are indeed drunk driving, even if you haven’t drunk, you have to find an excuse to collect your fingerprints and DNA.

Xiao Xu is doing business, and Tan Haichao has no choice but to go with him.

After completing the procedures, you can only deduct the car but not the person. However, when to return the car and how to punish drunk driving is the traffic police. Xiao Xu only needs fingerprints and blood samples to test alcohol content, and send the fingerprints and blood samples to the Criminal Technology Center based on the list before finding a second person.

The technical police officers are too busy. Not only does the DNA comparison result have to wait for a week before they can come out, but they also have to queue up for fingerprint comparison. After all, this is an old case. What's the harm in waiting for eleven years or more days? The job cannot be affected by this.

Time passed day by day, and there was no news.

Wei Guoqiang was a little anxious when he waited. Half a month ago, he said "please" that means no longer interfering with the task force's investigation. I don't know the results of the scrapped Municipal Party Committee Car No. 8. I didn't know. A few days ago, I didn't have the nerve to ask at the wedding of the People's Hospital doctor Tian Xuewen and forensic doctor Li Jiaqi of the Technical Investigation Detachment. Today I couldn't help but call to find out the progress.

"Xiao Han, the drug addicts have almost finished checking. The comrades drawn from the branch will ask them to go back tomorrow. I can't just hold on to Zhang."

He was anxious, but Han Bo was also anxious.

Before I knew it, I had invested more than 100,000 yuan in the 12.26 case, mostly by the technical investigation detachment. If I couldn't find out a bunch of invoices, who would I ask to report it?

There has been so much noise these days. If Zhang still paid attention to the Xunli case, he would immediately know that the bureau is re-investing the 12.26 case after he came out of the drug rehabilitation center.

It's nothing if he did it. If he did it, he would definitely alert the enemy.

Han Bo was in a difficult situation, staring at the names on the white blackboard and pretending to be relaxed: "Wei Detachment, don't you finish the work? If you really can't find an excuse to spend a few more days."

"It's okay for a few days, what should I do after a few days?" I haven't moved for so many years, just because I'm worried about alarming the situation. Wei Guoqiang is somewhat unhappy when the case is handled like this.

"Give me another week."

Han Bo took a deep breath and explained: "Wei Detachment, now the population is so large, it is difficult for you to know how difficult it is for grassroots comrades. Until today, the basic information collection of the criminal personnel who had been inspected that year has not been completed, and only half of it has been completed. The fingerprints of many people who were surveyed later have not been compared."

Times have changed. In the past, criminal technology was mainly used in major cases, but now, major cases must be managed as common cases.

As long as the site is subject to conditions, all investigations must be conducted, and the criminal investigation departments of the district and county public security bureaus have been continuously sent for inspection. The fingerprint database of criminal personnel who had just started to build has played a role, successfully linking more than a dozen theft cases, assisting the Yangtze River Branch and the Development Zone Branch to crack down on seven cases and arresting nine suspects.

Like the hospital laboratory, he is busy from morning to night. Wei Guoqiang knows these situations. The key is that the situation in this case is even more special. Once the suspect is alert, God knows what will happen next.

Just as he was about to ask if he was sure, Han Bo suddenly said: "Wei Detachment, I have some urgent matters here. I will wait ten minutes to go back to you."

"First, it's not necessarily ten minutes, and you'll be able to call me if you have time." The "old coach" still knew the priority and ended the call simply.

Han Bo put down his cell phone and stared at the traces that had just walked into the psychological test room. Sun Zhongchen, director of the literary inspection room, asked: "Director Sun, what's the situation?"

"Han Detachment, I've compared it, look at this!"

Sun Zhongchen opened the folder and pointed to the two fingerprints on the material and said with excitement and a little disappointed: "The dozen or so feature points are exactly the same, but Hailong cannot match them."

Although DNA is not comparable, this is also a breakthrough.

Han Bo was ecstatic and held the material tightly and smiled: "The owner of the dagger is not necessarily the murderer, and the owner of the fingerprint is not necessarily the murderer. Bloodstains, fingerprints, dna, three related people we have found. When we find the third one, the truth will be revealed."

"That's right, it shouldn't be difficult to find a third person to find a sharpener."

“Beautiful job!”

Han Bo patted his arm, put down the appraisal report and checked the list of inspectors according to the number, and then found the relationship materials with the female staff of the Seaman Club that year based on the list.

"It turned out to be her, it turned out to be him. Fortunately, Haibing works hard enough, otherwise he might have kept going to be at large."

"Han Detachment, you mean..."

"I wasn't sure just now, but now I'm sure."

Han Bo looked at the materials again and quickly called Su Haibing's mobile phone: "Su Da, I, Han Bo, have a good news, and the fingerprints were successfully compared. Suspect No. 47 is a major suspect in the crime."

"How could it be him?"

"Why can't it be him? Although he was not in Nangang before the incident, he was not far from Nangang. From the materials, he had full motivation to sneak back to Nangang to commit the crime, and then crossed the river overnight to Jiangnan. Because of this, although he was a released prisoner, he had investigated so many criminal cases that year but missed him, allowing him to stay away from justice until today."

He had the motive for committing the crime and the conditions for committing the crime, but it seemed that he was the one who did not do his job in vain and his funds were not wasted. Su Haibing was very excited to think that an old case was about to be revealed.

Han Bo continued: "The fingerprint comparison is not available, which shows that he is very cunning. He not only wants to prove it without being present, but also premeditatedly committing the crime with someone else's dagger. The arrest time is not mature enough. Please adjust the direction immediately and divide it into three groups. The first group investigates who the dagger belongs to based on his social relations at that time, the second group implements the grudge between him and the person he really wants to kill, and the third group investigates the possible relationship between him and Zhang."

The range is getting smaller and smaller, so it should not be difficult to check next. Su Haibing smiled and said, "Yes, I'll make arrangements immediately!"

Han Bo hangs up his phone and becomes more and more excited as he thinks about it. Thinking that "Old Shopping" is waiting for news, he hurried back.

After listening to the introduction, Wei Guoqiang found it incredible, but when he thought about the case, he was very reasonable, and murmured: "It seems that I suspected that I was wrong. Zhang is really innocent."

"It's not certain yet. When you find the dagger master and wait until all other situations are implemented, you will know the role he played in the entire case. After all, the bloodstains were in the car he drove at that time."

"No matter what, I finally found out. Xiao Han, thank you."

"Thank you, this is what I should do. Wei Detachment, until now, Director Chen doesn't know that we are investigating this case. Do you report it to Director Chen?"

"It's time to report, I'll call him now."

Han Bo thought about it and suggested: "It was difficult to check before, but there was no direction. Now that there was direction, the next work would be unstoppable. At most, I can figure out other situations in three days. You can ask the old leaders of that year to come and watch the interrogation, and even invite Deputy Mayor Li Haiqiang to come over to uncover the mystery together and give them an explanation."

"This idea is good. I'll call the old director and the others, Li Haiqiang, please contact me." It's been more than ten years, and it's time to give someone an explanation. Wei Guoqiang sighed and felt relieved.
