Amends the Juvenile Court Act of 1987 and the Code of Criminal Procedure of 1963. Provides that unreliable statements to law enforcement made during a custodial interrogation conducted at a police station or other place of detention by a defendant are inadmissible at trial in any criminal court proceeding or juvenile court proceeding. Provides that in any proceeding under this provision, the prosecution shall timely disclose at least 30 days prior to any relevant evidentiary hearing or trial its intent to introduce a statement made during a custodial interrogation conducted at a police station or other place of detention by a defendant. Provides that at that time, the prosecution must disclose any electronic recordings of the statement and any documents relating to the circumstances under which the statement was obtained. Provides that when deciding a statement's reliability, a court should consider: (1) whether the details in the statement fit with the evidence known before the interrogation, especially details that describe unusual or not easily guessed facts of the crime that had not been made public; (2) whether the statement provides any new details or any new evidence not known before the interrogation that can be independently corroborated after the interrogation; (3) whether facts of the crime were disclosed to the defendant rather than elicited from the defendant; and (4) whether a court has found evidence of coercion in making a prior determination about whether the statement is voluntary. Provides that the question of the statement's admissibility is solely for the trial court.
