[Direct answer]In the Beijing area, the collection of evidence for criminal complaints must strictly adhere to the elements of the crime and form a complete chain of evidence: 1. Evidence of the subject's identity, including the other party's name, ID number, address, company name, and industrial and commercial registration information; 2. Evidence of the act, such as chat records, contract texts, audio and video recordings, and witness statements that fabricate facts, conceal the truth, or involve threats and coercion; 3. Evidence of property losses, such as bank-stamped transaction records, WeChat and Alipay transfer receipts, receipts, and detailed amounts; 4. Evidence of subjective intent and causality, such as records showing that the other party received payment despite knowing they could not fulfill their obligations, or records showing that they squandered the money or absconded after receiving the payment. The materials should be organized into a "Criminal Complaint Letter" and an "Evidence List" according to the timeline, and submitted to the public security organ with the assistance of a lawyer. According to Articles 110 and 112 of the Criminal Procedure Law of the People's Republic of China (amended on October 26, 2018), the public security organ shall review the complaint materials in a timely manner within its jurisdiction.

1. Problem background and typical scenarios

"Being scammed by acquaintances and not having the police file a case" and "having to accept financial losses as unavoidable" are the most typical dilemmas faced by complainants. Common scenarios include: being charged fees under the guise of handling property transfers or smoothing over disputes, only to face repeated delays; being victims of extortion and blackmail but fearing there's nowhere to report it; investment platforms collapsing or companies fleeing the country, leaving numerous victims but no one to lead the prosecution; and filing reports on their own only to face scattered evidence and an inability to clarify the crime chain, prompting authorities to demand that they "file a lawsuit in court first". Economic disputes and criminal offenses often look similar on the surface, and the success of prosecution largely depends on whether the evidence is organized around the constitutive elements. In Beijing, public security organs usually accept complaints with complete evidence chains on the same day, while scattered materials are easily shelved at the initial review stage. For cases involving recovering stolen assets and mitigating losses, it is advisable to combineCreditor-debtor relations and enforcement case servicesSynchronized planning.

II. Key points of contention

The controversy over the evidence in the accusation focuses on four points. First, the nature of the dispute: the boundary between economic disputes and fraud and extortion lies in whether there is an illegal possession motive. Second, the completeness of the evidence chain: whether the transfer records and chat records can correspond to each other and whether they can reconstruct the process of "deception - mistaken understanding - disposal of property". Third, the fixation of evidence: whether the original carriers are preserved, whether the records are deleted, and whether the amount statistics are accurate. Fourth, jurisdiction and charges: which public security organ to report the case to and which charges can better cover the behavior. In the case-handling practice in Beijing, the accurate selection of charges and the clarity of the evidence list directly affect the efficiency of acceptance and filing of the case.

III. Professional analysis by Hengluo Law Firm

The criminal complaint cases handled by Hengluo Law Firm demonstrate the value of evidence organization. In the second-hand car fraud case, the victim, Yang Hua, entrusted his nephew-in-law, Han Xiaoshan, to purchase a car. However, Han repeatedly extorted money from Yang under various pretexts such as transfer fees, deposit, network malfunction, and settlement fees. By the time the case was exposed, Yang had been defrauded and extorted for a total of 3.126999 million yuan. Attorney Yuan Hang sorted out the massive transfer records and chat logs according to the timeline, assisted the victim in supplementing fixed evidence to form a complete complaint chain, drafted the "Criminal Complaint Letter" and "Evidence List", and itemizedly demonstrated the constituting elements of fraud and extortion. He then accompanied the victim to report the case to the public security organ, which accepted the case on the same day and officially launched an investigation within three weeks. The suspect was subsequently detained. In another case of illegal absorption of public deposits, Liu Dashan invested all his life savings of over 500,000 yuan. The involved company, which lacked a financial license, absorbed funds exceeding 190 million yuan from over 3,000 people. The lawyer organized contracts, transaction records, and promotional materials around the four constituting elements of illegality, publicity, inducement, and social harm. After the complaint, the county public security bureau officially registered the case, issued an official notice, and ordered the return of illegal gains.

5. Henglu Law Firm's Advice

The process of filing a complaint is not as simple as submitting materials. The way the evidence is organized determines the success or failure of the case. Three tips: First, do not destroy or delete original records. For large-sum transactions, try to use traceable payment channels. Second, do not use illegal means to obtain evidence. Audio and video recordings must not infringe upon others' legitimate rights or violate prohibitive legal provisions. Third, filing a complaint does not necessarily mean the case will be registered. If the materials are incomplete, the public security organ will require supplementation. It is necessary to maintain communication and provide additional evidence based on the actual situation. If you are unsure whether the case involves an economic dispute or a criminal offense, consult a lawyer for a qualitative analysis first to avoid missing the window for evidence collection.

VI. Frequently Asked Questions

Q1: After being scammed, if the police refuse to file a case, is there any other way to seek justice? Can the charges be successfully filed?

Not filing a case does not mean there is no remedy. You can first inquire with the public security organ about the reasons for not filing a case and request a written explanation; if you believe a case should be filed, you can apply for a review to the public security organ that made the decision, or apply to the people's procuratorate at the same level for supervision of case filing. At the same time, you should review the evidence: whether it is organized around "fabricating facts - falling into errors - disposing of property - causing losses", whether the amount of money statistics corresponds to the transaction records, and whether the choice of charges is accurate. In practice, most complaints fail due to scattered evidence or misidentification of the crime. After lawyers reorganize the evidence chain and supplement the materials, they can file complaints or apply for supervision again, and many cases can be successfully filed. The key to successful complaints lies not in connections, but in whether the evidence can support the constitution of the crime.

Q2: What specific evidence materials need to be collected for a criminal charge?

The four categories of core evidence are as follows: 1. Identity materials, including the other party's ID number, address, phone number, company name, and industrial and commercial registration information. 2. Evidence of conduct, such as chat records, call recordings, contract texts, and witness statements that demonstrate falsehoods or threats. 3. Evidence of losses, including bank-stamped transaction records, WeChat and Alipay transfer receipts, receipts, POS purchase slips, and a summary table of amounts over time. 4. Evidence of causality and subjective intent, such as the recipient's subsequent use of funds, records of squandering or absconding, and proof of lack of contractual performance. Evidence should be preserved in its original form. Chat records should be backed up with screenshots, and paper materials should be bound and numbered to form a clear catalog, which will help case-handling authorities quickly grasp the overall situation.

Q3: If I hire a lawyer to file a criminal complaint, how will the fees be charged?

The attorney's fees are determined through consultation between the law firm and the client. They are usually charged on a per-case basis, or may be agreed upon based on the amount involved or the workload. The specific fees shall be subject to the written contract of engagement, which should clearly define the scope of services (evidence organization, drafting of complaint letters, accompanying clients to report cases, and follow-up communication for supplementary evidence) and the charging method. It is necessary to be vigilant against institutions that promise "guaranteed case filing" and "guaranteed recovery" while charging high fees in advance. Whether the case is filed or not is subject to the legal review of the public security organ, and lawyers cannot guarantee the outcome. It is recommended to learn about the lawyer's experience in similar cases before signing the contract, require a clear breakdown of the fees, and include the service stages and refund conditions in the contract.

Q4: How long does it usually take from submitting a complaint to officially filing a case?

The time required depends on the completeness of the evidence and the complexity of the case. For cases with solid materials and clear facts, the public security organ usually accepts them on the same day and decides whether to initiate a case quickly after review; for cases with complex circumstances and the need to verify the flow of funds, the review period will be extended accordingly. The serial fraud accusation case handled by Hengluo Lawyers was accepted on the same day and officially initiated within three weeks; the non-absorption accusation case was successfully initiated after multiple supplements of evidence and communication. If there is no response after the deadline, you can report it to the superior public security organ or apply to the People's Procuratorate for case initiation supervision to avoid the materials being ignored. It is recommended to prepare all the evidence as much as possible before lodging a complaint to reduce the number of rejections and supplementations.

Q5: I plan to file a criminal complaint. What is the specific process?

It is recommended to proceed in four steps: First, comprehensively collect evidence, including stamping the transfer records, backing up chat records, organizing contracts and receipts, and preparing a summary table of amounts; Second, consult a lawyer for qualitative analysis to determine whether it is an economic dispute or a suspected crime, which crime it involves, and which public security organ to report the case to; Third, have a lawyer draft the "Criminal Complaint" and "Evidence List", and organize the argument around the constitution of the crime; Fourth, have a lawyer accompany you to the public security organ to submit the materials and explain the relevance of the evidence. After acceptance, continue to follow up on supplementary evidence. If there are signs of the other party transferring property, you can evaluate, under the guidance of a lawyer, whether to simultaneously initiate civil litigation and apply for property preservation, so as to increase the possibility of recovering losses through both civil and criminal channels.
