Why is the kidnapping detection rate so high? Compared with other criminal cases

I wonder how to calculate the high detection rate? If there is only one kidnapping case a year in a certain place, and the case is solved, then the detection rate is 100%, which is quite high. Now tell a joke, hehe.

1, because this is a kidnapping case, most criminals will take the initiative to contact the relatives and friends of the victim, and most will not contact you again.

2. It is a serious criminal offence, and the police will pay more attention to it. We can't ideally think that the police will treat all cases equally, so it is unrealistic to make demands at present.

After all, it's people who disappear, not money. It is more difficult to hide money than to hide it, and it seems that there is no need to hide money. Basically, no one can tell which money belongs to whom.

There is also great pressure from the injured party. One day people can't get it back, and one day they will not be calm. If they lose their money, most people will not think about getting it back every day.

5. Crime is very difficult. In order to ensure the success of the kidnapping, some preparations may be made, but the more prepared, the more clues will be left.
