подозреваемый

Also known as crime suspect, suspects, crime suspects, criminal suspect, suspect of a crime, alleged perpetrator, suspected perpetrator

In law enforcement jargon, a suspect is a known person accused or suspected of committing a crime. By definition, a suspect is distinct from the perpetrator of the offense (perp, in dated U.S. slang), though in the United States, the word suspect is often used as a jargon when referring to the perpetrator. The term is also related to the terms defendant, the accused, person of interest, and prime suspect.
