On February 7 this year, Chimou, a resident of Yanji City, reported that his wife Jin Hong (a pseudonym) and his stepdaughter Jin Xiaoli (a pseudonym) lost contact after leaving home. The preliminary investigation by the public security organs found that Chi's statement was seriously inconsistent with the investigation. The evidence shows that Jin Hong's mother and daughter are likely to be killed, and Chi is suspected of committing a major crime. On February 1 1, the public security organ put on record for investigation. After several contests, the suspect Chi confessed that on February 5, he quarreled with Jin Hong at home because of trivial matters and killed him, and then killed his stepdaughter Jin Xiaoli, and then destroyed his body.
Only the confession of the criminal suspect is far from being able to effectively accuse the crime. On the second day after the public security organs filed a case for investigation, Yanbian Prefecture Procuratorate intervened in accordance with the law to guide the investigation and evidence collection, held seven case analysis meetings successively, carefully studied the nature of the case, determined the investigation direction, actively guided the public security organs to find evidence according to the trial standards, searched more than 30 garbage dumping sites in the city, visited dozens of garbage dump owners, sanitation workers, local residents and so on, cleaned the septic tanks of the first and second stations, and arranged for more than 40 people to collect at Yanji's largest garbage landfill.
Five people, including investigators, DNA appraisers and garbage dump workers, appeared in court successively. The prosecutor produced 13 sets of evidence including expert opinions, investigation and experiment transcripts, videos, telephone calls and WeChat records. The defense lawyer and the defendant did not object to the evidence.
