Crime and investigation The
respondent Michael Alvarado agreed to help his friend Paul Soto steal a truck in the parking lot of a shopping mall in
Santa Fe Springs,
California. Soto pulled out a gun and approached the driver of the truck, demanding the keys, while Alvarado hid by the driver's side door. The driver refused and was shot and killed by Soto. Afterwards, Alvarado helped hide the gun. Los Angeles County Sheriff's detective Cheryl Comstock led the investigation of the crime. During the investigation Comstock contacted Alvarado's parents, saying that she wished to speak with Alvarado. Alvarado's parents brought him to the police station to be interviewed. Comstock brought Alvarado into an interview room and questioned him for two hours. Alvarado's parents asked to be present during the interview but were not allowed in by police. This would form part of the basis for Alvarado's legal defense.
Trial and conviction The State of California
charged Alvarado and his friend with
first-degree murder and
attempted robbery. Alvarado attempted to
suppress his statements given during the Comstock interview on the basis that he was not read his
Miranda rights. The trial court denied the motion on the basis that Alvarado was not in police custody at the time he gave his statement. Alvarado was subsequently convicted, primarily based on statements Alvarado made during his police interrogation. Alvarado's conviction was reduced by the trial judge to second-degree murder for his comparatively minor role in the offense. The
Supreme Court of California declined discretionary review. Much of Alvarado's trial focused on whether Alvarado was in custody or not during his police interview. According to
Thompson v. Keohane, to determine whether someone is in custody the courts apply a reasonable person test: whether a reasonable person would have felt free to leave or not.
Petition for habeas corpus After his conviction, Alvarado filed for a writ of
habeas corpus claiming that the custody analysis was incorrect because the court had not considered Alvarado's age in its reasonable person test. Under the
Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), a federal court can grant
habeas corpus to a person held due to a state court judgment if the state court judgement "resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States". Alvarado's habeas corpus petition thus depended on demonstrating that the state court's custody determination was more than debatable, but objectively incorrect. The
United States District Court for the Central District of California agreed that the state court rulings were correct; however, the
Court of Appeals for the Ninth Circuit reversed. The Court of Appeals held that the state court made a mistake in not accounting for Alvarado's youth and inexperience when evaluating custody. ==Oral argument==
