The Invocation and the Second Detective
At 1400, Officer Diaz arrests Marcus for assault-family violence. At the station, Diaz reads Miranda warnings from a card. Marcus says, "I don't want to talk to you." Diaz stops and books him. At 1630, Detective Lee, who is investigating an unrelated burglary, learns Marcus is in custody, brings him to an interview room, reads Miranda again, and asks about the burglary. Marcus says, "I'll talk about that." He confesses to the burglary. At 1700, Lee asks about the assault, and Marcus says, "I already told you I don't want to talk about that."
1. Is Marcus's burglary confession admissible? Analyze the invocation, the break in interrogation, and the fresh warnings.
Read the worked answer
It depends on whether Marcus unambiguously invoked his right to remain silent and whether the officers scrupulously honored that invocation. "I don't want to talk to you" is a fairly clear invocation of silence as to Diaz. Once invoked, interrogation must stop. Under Michigan v. Mosley, police may later re-interrogate the suspect about a different offense if they honor the invocation, wait a significant time, and give fresh Miranda warnings. Here there was a 2.5-hour break, a different detective, a different offense, and fresh warnings. Those facts favor admissibility.
If Marcus had invoked his right to counsel, Edwards v. Arizona would bar further interrogation unless counsel was present or Marcus initiated the contact. He did not ask for a lawyer. The stronger argument is that the burglary confession is admissible under Mosley, but the court will scrutinize whether the first invocation was honored and whether the second interview was genuinely about a different matter.
2. Can Detective Lee use the burglary confession as leverage to question Marcus about the assault? What should he do when Marcus re-invokes?
Read the worked answer
Lee should not use the burglary confession as a wedge to override Marcus's re-invocation about the assault. When Marcus says, "I already told you I don't want to talk about that," that is a renewed invocation as to the assault. Lee must stop questioning about the assault immediately. He may not continue to wear him down, and he may not tell Marcus that talking is the only way to help himself in a way that undermines the invocation.
Lee can book him and document the invocation. If investigators later want to question Marcus about the assault, they should wait, give fresh warnings, and ensure that Marcus initiates the contact. Using the burglary admission to pressure him into discussing the assault risks suppression of the assault statement and may taint the burglary statement as well.
3. What is the significance of the magistrate warnings under Texas law, and could the delay affect admissibility?
Read the worked answer
Texas law requires that an arrested person be taken before a magistrate without unnecessary delay, generally within 48 hours, and receive statutory warnings about the right to remain silent, the right to counsel, and the right to an examining trial. A delay in magistrate warnings does not automatically suppress a confession. Courts ask whether the delay was unnecessary and whether it produced the statement or otherwise caused prejudice.
Here Marcus was arrested at 1400 and interviewed at 1630, so the 48-hour window had not run. The more important issue is Miranda, not the magistrate warning. Lee should still document when Marcus was magistrated and ensure the statutory warnings were given. If the magistrate warnings were delayed and used to obtain the confession, defense counsel could challenge admissibility, but the facts here do not show that.
