"Well! Let's first figure out the time when his life changed, and then we can investigate in depth."
Wu Rui thought for a while and nodded.
Chen Luo and Ding Xiuyong both nodded in agreement.
"In this case, Xiu Yong, you stay in the institute, while Xiao Chen and I go to Yuan County to learn about his situation before he moved to the city."
Wu Rui then made arrangements.
Zhang Yuanbai and his wife bought their house in the city eight years ago.
And his eldest daughter is already twelve years old.
Basically, it can be inferred that Zong Yuanbai's living situation has improved for the better when he was in the county.
"Okay Master."
Chen Luo naturally had no objections to this arrangement.
What was the purpose of what he said before? It was to guide Master to check forward.
What Chen Luo didn't expect was.
How could my master be so cooperative?
Follow his lead and infer.
At the same time, I sighed in my heart, Master is indeed a veteran policeman who has been in the police for many years.
Rich experience, can tell at a glance.
If it were Ding Xiuyong, this senior brother who came in only two or three years before me.
It was designated that it would take a lot of effort to guide him there.
Of course, Chen Luo also knew that the main reason was that his position was established and his master trusted him.
Otherwise, I'm afraid it wouldn't be so easy.
Ding Xiuyong naturally had no objection to Wu Rui's arrangement and immediately nodded in agreement.
Wu Ruixian then contacted the police station personnel in Yuan County.
Then he took Chen Luo to Yuan County.
It takes about forty minutes to take the expressway from the city to the county seat below.
But it takes almost forty minutes to get from the city to the highway entrance.
After arriving at the Yuan County Police Station, I met with the police here and immediately went to Zhang Yuanbai’s village committee to learn about the situation.
Zhang Yuanbai's family was originally relatively poor.
Two brothers.
Zhang Yuanbai dropped out of school early to work.
At first he worked in the county town, and then when he was twenty-one years old, he went to work far away.
But I only worked for more than a year and came back around October of the next year.
When he came back, the highway happened to pass through the village, and his family's land was expropriated, so he came over with some money.
then!
Zhang Yuanbai began to tinker with business.
He is also quite talented in business. He gets better and better as he gets better and better, and his living standard improves linearly.
Then he married a wife soon after.
Then a daughter was born.
After a few years, I moved to the city.
The village committee didn't know much about what happened next. They just knew that he was living a good life in the city and had opened a company.
After learning about these situations.
Wu Rui and Chen Luo thanked them, said hello to the police at the police station, and drove directly back to the city.
"Xiao Chen, it seems that the murder that Zhang Yuanbai was carrying was probably committed while he was out working."
Wu Rui said speculatively while driving.
"Well, I also think the murder should have been committed at that time, and it was most likely committed during the period before he came back."
Chen Luoying agreed and gave a more specific time point.
Although Zhang Yuanbai's voice only mentioned fifteen years ago, he did not mention the specific point in time.
But judging from the situation.
Basically it can be inferred.
When I went out to work more than ten years ago, unless something happened to my family, I would basically never come back.
And when Zhang Yuanbai came back halfway, there was no change at home, so it was probably because of the change on his side.
"Well, that's very possible. After I get back, I'll contact Yangshi first to see if there are any unsolved cases there that have been pending until now."
After hearing this, Wu Rui spoke in agreement and made arrangements for the next step of investigation.
"Uh-huh."
After hearing this, Chen Luo responded twice in agreement.
It took the same amount of time to return to the institute.
Wu Rui took advantage of the time before getting off work and immediately went to check the contact number of the person responsible for the backlog of cases at the sheep market.
It took some effort to get in touch.
Then explain the situation relatively simply.
Of course it is processed.
It's just that a person was found here who probably committed a murder in Yangshi fifteen years ago.
I want Yangshi to check if there are any pending murder cases during that time.
The person in charge of the backlog of cases in Yangshi was just slightly stunned after hearing Wu Rui's call, and immediately said he wanted to check it out.
He is responsible for the backlog of cases, and the calls he makes are basically related to the backlog of cases.
I just didn't expect that this call actually came from Longsheng City.
After ending the call, Wu Rui, Chen Luo, and Ding Xiuyong were waiting in the office.
It's past the time to get off work.
Waiting for a call back.
In the time period before Zhang Yuanbai returned to his hometown, there were two murder cases pending until now.
There are two other cases that occurred in the same year, three and five months respectively after Zhang Yuanbai returned home.
Two murders during that time period.
Together they are indoors and together they are outdoors.
There was a home invasion and robbery inside, which happened late at night. The female owner was killed, while the male owner was away on a business trip due to work requirements.
Outside, in an alley, around nine o'clock in the night, a young woman was killed and her belongings were lost.
No fingerprints were left in either murder case, but the killer's skin was found in the victim's fingernails and DNA was detected.
Although DNA data is available, no suspect has been found, and the case remains unsolved until now.
The circumstances of the two previous murder cases were roughly similar.
"One was an indoor robbery and the other was an outdoor robbery. Both are possible. We only need to take Zhang Yuanbai's DNA and compare it to confirm."
After listening to the four materials, Ding Xiuyong was the first to express his opinion.
"If it's one of these two murders, that's fine. If it's not, it will definitely alert the snake."
Wu Rui shook his head and said.
"We have to find a way to get his living DNA without being discovered by Zhang Yuanbai."
Chen Luo thought for a while and gave his opinion.
"Well, this is the safest way to do it, but it's not easy to do so."
Wu Rui agreed, then frowned slightly and said.
"Master, it's not difficult."
Chen Luo shook his head and said.
"You have a solution!"
Wu Rui asked with eyes brightening upon hearing this.
Ding Xiuyong immediately set his sights on Chen Luo.
"Zong Yuanbai has children, and they all go to school. We can definitely start from this aspect."
Chen Luo smiled and expressed his thoughts.
"That's right! Why didn't I think of this method?"
Wu Rui's eyes suddenly brightened even more, and he said in agreement, and finally patted his forehead with some annoyance.
Ding Xiuyong's eyes lit up after hearing this, and a look of annoyance appeared on his face.
I blame myself for not thinking of this.
Chen Luo smiled when he saw the two of them like this and said nothing more.
"School is over now, so it's hard to move. So, tomorrow morning, we will go to the school to ask the principal for help."
Wu Rui then looked at the time, shook his head, and then made a decision.
Chen Luo and Ding Xiuyong naturally had no objections to this and nodded in agreement.
