Information gathering interviews for suspects were developed with the aim of preventing the risk of false confessions and false prosecutions embedded in the confession obtaining interviews. Information gathering interviews such as PEACE model, SUE, TIM, and GIS have the advantage of reducing the risk of false confession and instructing whether the suspect is the criminal or not, but in the case that the suspect continues to deny or refuse the statement, there is a limitation that it cannot show investigators the methods after that. In this paper, I propose the use of oratorical persuasion, appeal to interest, and minimization as a persuasive interview strategy for the suspects who continue to deny after using the information gathering interview. These three strategies are highly correlated with humanitarian interview strategies, induce ‘internal pressures', and do not imply generous penalties, so the risk of false confessions is low. When an investigator use the persuasive interview strategy, there are some precautions. It must be used only after the information gathering interview has been used. The suspect must be given the opportunity to deny. The details of the crime should not be mentioned. The time of persuasion should be limited. And it should not be used for vulnerable people.
