What evidence is needed to prove that the suspect has committed a crime in criminal detention or investigation of criminal responsibility?

2. As long as there is certain evidence, criminal detention can be taken. For example, to identify or find the victim at the scene, please refer to Article 6 1 of the Criminal Procedure Law. To bear criminal responsibility, there must be enough evidence to prove it, that is, there must be enough evidence to form a chain of evidence in order to be convicted and sentenced and bear criminal responsibility. Arrest is a more severe criminal compulsory measure than detention. According to the Criminal Procedure Law, "a criminal suspect or defendant who has evidence to prove that he has committed a crime and may be sentenced to more than fixed-term imprisonment is not enough to prevent social danger, but if it is necessary to arrest, he should be arrested according to law." There is no hard and fast rule for this evidence. In practice, there must be at least multiple evidences to prove it. Follow-up: the chain of evidence is a material chain that can confirm each other, exclude other possibilities and finally prove the crime. For example, fraud: 1, the materials confessed by the suspect himself; 2, the victim's statement materials; 3. Other witness materials; These materials can prove each other, conform to the objective reality and prove the crime. Because a single evidence can't convict. For example, if the suspect does not confess, this kind of crime can only be identified by the victim, unless there are other witnesses to prove that it is consistent with what the victim said, plus physical evidence or documentary evidence. Follow-up: The fact is that the customer received RMB30,000 from the customer and delivered 1.6 million, of which 1.4 million was not delivered in time. Last month, on the 7th, when the client went to see him, something happened. What happened is still unclear. The next day, he told his family that he had been cheated and should bear legal responsibility. And return the payment of 1.4 million to the customer on the 8th of the next day. The client dropped the lawsuit and found the client. The customer said not to pursue it, because it was nothing serious. The unit came forward for bail and was not allowed. Then the police station introduced an intern lawyer, without telling his family the specific situation or saying how to defend himself. Just say you want money to pay off. Later, a second lawyer was sent, and the client was not seen. Today is a month. He also said that people can pay 30 thousand in 37 days. Otherwise, let him give 20 thousand a few months ago Other evidence is nothing. Anyone with a discerning eye can see that if he deliberately defrauded the payment, how could he go to see the customer? And he didn't take out the money to spend. Our family already knows that this is a scam. We estimate that it does not constitute fraud at all, but a general civil contract dispute. But the public security organs just won't let people go, which makes us very helpless! ! ! Follow-up: What should I do? We believe that if the inspection agency is fair, people should be released without being arrested. But if they all collude, it's over. I am very anxious at home, but because of family reasons, no one can afford such a thing. Ordinary people, the client's father died, his mother was seriously ill, and his brother had to support his family. Tens of thousands is not a small number. I really don't know what to do. If the family is really guilty, it will be punished by society, but you know it is wrong to do so, but you don't know what to do. Ask friends to give some advice or suggestions, thank you! ! !
