No. The Prosecuting Attorney's office only authorizes a criminal complaint; the court authorizes an arrest warrant, and the police department that investigates the case has the responsibility to find and arrest the defendant. The Prosecuting Attorney's office may not know if an arrest warrant is still outstanding, because that information is known by the police and the court. The defendant (or anyone asking about whether a warrant is still open) must contact the police agency handling the case. That department may be able to answer the question.
If the Prosecuting Attorney's office told a defendant that an arrest warrant was still outstanding, the defendant might flee.
