With the help of Fisher Discriminant Analysis method and Criminal Network Core-figure Discovery (CNCD), a threshold discriminating non-conspirators from conspirators and the leader of the crime network can be obtained. The paper starts with a small network model, the result may even be used for other fields´ network mining and core determination, which has important theoretical significance and application value.
