  In this paper, we present a Virtual-Suspect system which can be used to train
inexperienced law enforcement personnel in interrogation strategies. The system
supports different scenario configurations based on historical data. The
responses presented by the Virtual-Suspect are selected based on the
psychological state of the suspect, which can be configured as well.
Furthermore, each interrogator's statement affects the Virtual-Suspect's
current psychological state, which may lead the interrogation in different
directions. In addition, the model takes into account the context in which the
statements are made. Experiments with 24 subjects demonstrate that the
Virtual-Suspect's behavior is similar to that of a human who plays the role of
the suspect.
