Once Rivas invoked his right to counsel on March 18, however ambiguously, the detectives were required to clarify the ambiguity or cease questioning. The detectives did neither. Instead, the detectives interrogated Rivas for nearly six hours, eliciting a confession. After the improper interrogation and Rivas’s tainted confession -- a confession Rivas had reason to believe was lawful -- Rivas asked to see the detectives again. Those remarks cannot be fairly characterized as Rivas voluntarily initiating further communications with the detectives because the questioning never truly ceased. The interrogation and the request to speak again with the detectives were inextricably intertwined.
