Defendant voluntarily went to the police station to give a witness statement. At the police station, defendant was interviewed twice. During his first interview, defendant was not in custody and thus not yet owed Miranda warnings. The factors set forth in O’Neill therefore do not need to be considered to assess the admissibility of the second interview. And before police interviewed defendant the second time, they properly administered Miranda warnings. With his rights in mind, defendant executed a knowing, intelligent, and voluntary waiver. During his second interview, defendant confessed. Neither the Fifth Amendment nor state common law calls for suppression of defendant’s statements.
