Du Dayong listened to Du Wei's words and tilted his head to glance at him.
"Du Wei, as a criminal policeman, you must be able to calm down, hold on to your weaknesses, let go of your thinking, fight on your patience, and show your intentions."
"Although I haven't been a criminal policeman for a long time, I have always asked myself so much. This is what an old detective said to me when I was internship in Guangdong Province."
After hearing this, Du Wei nodded thoughtfully.
Chen Wei, the assistant police officer driving in front, nodded after hearing this.
Du Dayong knew that this auxiliary police officer who drove was also preparing to take the police examination this year, two years older than him.
Three days passed in a flash. During these three days, each group basically got up early and touched late, but there were very few clues.
On the morning of the fourth day, it was still the same small conference room. In addition to the members of the three groups, there were six additional six auxiliary police officers who visited and investigated together.
Du Dayong invited them to come, and wanted these auxiliary police to make up for the time when the team members might have omissions.
Xue Tianhang was the first to conduct a survey and report.
"Great use! In the past three days, our team has basically surveyed all the emergency centers and ambulances with first aid qualifications in the city and surrounding counties, but no ambulances have been found to have tracks that went to Xiaohe Village on the night of New Year's Eve."
"In addition, we also conducted visits and surveys along the way. On New Year's Eve, no village or town had any families in need of first aid along the way."
Du Dayong nodded, letting Xue Tianhang understand that he knew.
"Team leader, Luo Xin and I also retrieved all police cars from all cities and suburban counties on New Year's Eve. There was no record of police dispatch near Xiaohe Village. However, along the way, there were households in Jinwei Village, not far from Xiaohe Village, who called the police."
"But we also checked it. It was because there was a conflict between the two sisters-in-law on New Year's Eve, so the police were sent out. We have copied and brought back the entire police call. Apart from this situation, no other abnormal police call was found."
Du Dayong still nodded.
"I am the same as you. In the past few days, I have visited all crematoriums in the city and suburbs that are formally engaged in the funeral industry and those with specific business licenses with the qualification to pick up and drop off the body. I have not found any records of driving to Xiaohe Village on New Year's Eve."
"So I consulted people from related industries, and they said that the funeral industry is actually very chaotic. Sometimes a van pulls a little black cloth and can instantly turn into a hearse."
"I was wondering, could there be such cars and people pretending to be people from this industry and throwing corpses through such means?"
"So, we have basically ruled out ambulances and police cars now, so we will focus on this and start a comprehensive visit and investigation. I believe that people in the formal funeral industry must have some inside information that we need to visit and investigate seriously."
"So I'm short on the story. It's still three days to divide it into three groups and conduct investigations and visits in different parts, especially in grassroots police stations to ask some old police officers. They all have some ways to understand these situations. Understand?"
"I understand!" "I understand!"
The entire three groups have been visiting and investigating this week, but after three days, they still failed to find effective clues.
At this time, Du Dayong had to focus on Wei City, Yandao City and Nikko City near Qinglu.
However, this investigation scope is a bit wide.
Du Dayong decided to survey the permanent population of Xiaohe Village and several villages near Shanghe Village who have been engaged in the funeral industry or who have temporarily lived here.
This investigation really found out the trick.
In the census of nearly 100,000 people, three groups screened out seven families familiar with the local terrain and later moved to other cities.
Among them, there is one in Liao City, two in Yandao, two in Wei City, one in De City, and one in Jicheng.
At this time, Du Dayong had to ask for help from the brigade because there was not enough manpower.
