On Sunday, March 25, Du Jiazhi, the murdered girl, was about to go to her grandparents' house after lunch, and her father, Du Menghai, planned to drive her there as usual. The girl is precocious, although she is only 13 years old, she is one meter five or six tall, like a little adult, and she hopes to take the 202 bus by herself. Du Menghai disagreed at first, the child said that the No. 202 bus has a stop sign at the entrance of the community of his grandfather's house, and he can make a phone call first and let her grandparents pick her up at the gate of the community. Du Menghai didn't think it was inappropriate, so he agreed. ”

I have been to the scene and listened to the report of the criminal police brigade of the sub-bureau.

Later, the sub-bureau could not be broken, the city bureau intervened, and the case analysis meeting was held countless times, and the case file materials were almost rotten. Cheng Wenming introduced the facts of his case, not only did he not need to look at the materials again, but he didn't even have to deliberately recall.

He lit a cigarette and continued: "Du Menghai is a native of this city, doing stone business, there is a stone processing factory under the bridge diagonally opposite Xinhua Decoration City, I am sure that my daughter does not need to send it, and I drove back to the processing factory alone." As a result, when I went to my father-in-law's house in the evening, not only did I not receive my daughter, but my father-in-law and mother-in-law said that Zhizhi had not called them and did not know what Zhizhi was going to do.

He thought that the child was lying, that the child had secretly gone to play somewhere in the afternoon, and he didn't care much at the time, so he drove back to his home in Newport Garden. When I got home, I found that the security door was locked, and when I opened the door, I saw that it was empty. He hurriedly dialed the teacher's phone, and the teacher inquired about the contact information of the parents of the child's classmates, and confirmed that his daughter had visited the mall with the other two girls at about two o'clock in the afternoon, said goodbye at about half past three, and then left. ”

"Han Bureau, Du Menghai's house is here, the child's grandfather's house is here, this is the shopping mall that the child went to in the afternoon. Zhou Suying tacitly took out her mobile phone and opened the electronic map.

The South Port has changed a lot, and the old city has not changed much.

Looking at the electronic map, Han Bo had a general impression in his mind.

Cheng Wenming and Wang Jiefang glanced at each other and continued: "After contacting the parents of other children, and then contacting relatives and friends, Du Menghai waited while calling frequently, and even ran to the gate of the community to wait, but his daughter did not come back at 9 o'clock in the evening. He was so anxious that he hurriedly informed his wife Shan Rui, who was studying in Jiangcheng. Shan Rui felt that something was wrong and told him to go to the police station to report to the police, worried that the child had been abducted and trafficked. ”

"What does the child's mother do?" asked Han Bo in a low voice.

"The doctor, to be exact, should be a technician, who does X-rays, CTs, and MRIs for people, and works in the Second Municipal Hospital. Li Jiaqi was very saddened by the unfortunate murder of the little girl, and couldn't help adding: "Xuewen has seen Shan Rui, but he didn't talk much, and he has a little impression of her." ”

There is no doubt that this would have been a very happy family.

Han Bo was also saddened, nodded slightly, and motioned for Cheng Wenming to continue.

"The Korean Bureau, you know the overall law and order in Nangang, we attach great importance to trafficking cases, and this is the first case of a missing child in the past three years. For the loss of children, the police station will directly file a case for investigation and report it to the criminal police brigade of the municipal branch in a timely manner. The sub-bureau activated the plan and soon dispatched some volunteers, security personnel and police to carry out a carpet search in Xingang Garden, Red Star Shopping Mall and the child's grandfather.

After 11 hours of fruitless searching, the sub-bureau decided to expand the scope of the search and issued a notice of assistance to each sub-bureau through the municipal bureau. Lost for such a long time, at that time, there were two possibilities of being abducted and kidnapped, if it was a kidnapping, someone needed to wait for the kidnapper's call at home, and the sub-bureau asked Du Menghai and Shan Rui, who rushed back from Jiangcheng overnight, to wait at home, and at the same time recall whether they had offended anyone.

Minutes and seconds passed, and nearly 29 hours of searching were carried out, but no news came, and there were no phone calls for kidnapping and ransom. Until 4:21 p.m. on March 29, a walker called the police to report that a charred corpse was found in a small park near the Yonghe community in Nanzhou, the body was very petite, like a child. ”

Next is the matter of Nanzhou District, and Wang Jiefang, deputy director of the Criminal Investigation Bureau of the Nanzhou Branch, took over the conversation without giving up.

"After receiving the instructions from the 110 command center, we immediately dispatched the police, and because we had received a report from the investigation before, we also contacted the Chengdong Public Security Bureau and asked them to send someone to see if the body was the same person as the missing girl. The Chengdong Branch asked Du Menghai about the clothes the child was wearing on the day he lost it, as well as what features the child had, such as scars on the skin or characteristic hanging ornaments.

Du Menghai said that the child has a long scar on his abdomen, which was left by surgery for appendicitis when he was a child, and there is a cartoon electronic watch on his left hand, and the strap is pink. The criminal police of the Chengdong Branch rushed to the scene with these clues, and together with us, they found an unrecognizable watch on the charred corpse, which should be the children's watch that Du Menghai said, and the unburned part of the strap was pink. As for the scar, Jiaqi later confirmed when she examined the child's body that it was indeed left by appendicitis surgery. ”

"In order to ensure that nothing is lost, we also extracted biological samples and did a paternity test, and the genetic marker characteristics showed that the victim was indeed Du Menghai's daughter Du Jiazhi. Li Jiaqi hurriedly added.

"This result was unexpected by everyone, and it could not be concealed, so parents could only be informed of the news of their child's death. According to the criminal police of the Chengdong Branch, hearing the bad news, Du Menghai cried loudly, and Shan Rui fainted on the spot. ”

The criminal police of the Chengdong Branch only thought about trafficking and kidnapping, and never thought that there would be a murderous result, perhaps they thought of it and did not want to mention it, but these are no longer important.

Cheng Wenming sighed secretly and said solemnly: "Because Shan Rui's spirit suffered a major blow and he was unable to answer the question normally, the police of the special case team of the sub-bureau only asked Du Menghai at that time, and basically ruled out the possibility of vendetta through questioning, but it cannot be completely ruled out that the death of the deceased was related to his classmates or the parents of his classmates. In order not to delay the investigation, we waited for the results of the forensic examination while conducting an investigation around the deceased.

The task force is divided into a number of 'Liaison Investigation Teams' (Interpersonal Investigation Teams) to investigate the entire class and their parents. After a week of investigations, no list of suspects was drawn up, because none of them had a motive to commit the crime, and almost all of them had an alibi at the time of the crime. ”

"We have also done a lot of work," Wang Jiefang said helplessly: "The child's body was found in our jurisdiction, and a deputy captain of the criminal police brigade of our sub-bureau and 16 police officers joined the special case team to participate in the investigation, and 519 copies of the interrogation records were made alone, and all the people related to Du Menghai, especially the murdered girl, were investigated and confirmed with alibi, and even the activities of the sweeping aunt and the security guard at the gate of Xingang Garden were implemented.

It is easy to do with a clear witness, but if there is no clear witness, you can only go to the monitoring, and then cross-compare and verify the testimony of other indirect witnesses who cannot directly prove the person under investigation, until it can be determined that the person's alibi. To put it mildly, we did our best to find the murderer of the child. ”
