The term 'TYPE OF SUSPECTS' can be summarized as referring to the USUAL suspects in a criminal investigation. This term is used to describe the people who are most likely to be involved in a crime, based on their past behavior or other factors. These suspects are usually the first people that law enforcement looks at when trying to solve a crime. The term 'USUAL' is often used to refer to these suspects, as they are the ones that are most commonly associated with criminal activity.
