Michigan v. Mosley

Richard Mosley (defendant), arrested for robbery, was given Miranda warnings and invoked his right to remain silent, after which the officer immediately stopped questioning him. Later, a different detective gave Mosley fresh Miranda warnings and questioned him about an unrelated murder; this time Mosley did not invoke his right to silence and made incriminating statements, leading to a first-degree murder charge. Mosley moved to suppress the statements, arguing the later questioning violated Miranda because it occurred after he had earlier invoked his right to silence, but the trial court denied the motion and he was convicted.
