RESPONDENT: Carl Mathiason
LOCATION: Oregon State Police

DOCKET NO.: 76-201
DECIDED BY: Burger Court (1975-1981)
LOWER COURT: Oregon Supreme Court

CITATION: 429 US 492 (1977)
DECIDED: Jan 25, 1977

Facts of the case

An Oregon state police officer suspected Carl Mathiason of burglary and asked him to come to the police station for questioning. Mathiason came freely, spoke with the officer, and was not arrested at the time. He was arrested later and a trial court used evidence obtained during the questioning to convict him. Mathiason moved to suppress the evidence since he was not read his Miranda rights before the questioning. The court admitted the evidence since Mathiason was not in custody during the questioning. The Oregon Court of Appeals affirmed. The Supreme Court of Oregon reversed since it found that Matianson was in a "coercive environment" when questioned and therefore deserved to hear his Miranda rights.

Question

Can incriminating evidence obtained from a suspect during a voluntary interview be used if the police did not read Miranda rights to the suspect?
