Background
Miguel Angel Santana was charged in Charles County with murder and related offenses arising from the 2016 killing of Lydell Wood. Before the first trial (Santana I, 2019), the parties agreed to exclude evidence of firearms, ammunition, and marijuana recovered during a search of Santana’s home. The jury convicted on two counts but hung on four others, resulting in a mistrial on those counts. Santana received a life sentence on the conspiracy conviction.
At the retrial on the four remaining counts (Santana II, 2023), the State again called Corporal Stephen Cartwright of the Charles County Forensic Science Unit. While questioning Cartwright about photographs from the search, the State asked what he had collected from the master bedroom. Cartwright responded that he had collected “firearms and marijuana”—the very evidence the parties had agreed to exclude. The State acknowledged it had not specifically instructed Cartwright to avoid mentioning those items, though it had prepared him generally. Defense counsel moved for a mistrial, which the circuit court granted over the State’s preference for a curative instruction.
Facing a third prosecution, Santana moved to dismiss, arguing that Maryland’s common law double jeopardy prohibition should bar retrial when the State’s reckless conduct—not merely intentional goading—caused a defendant to successfully move for a mistrial. He contended the State was reckless in failing to instruct Cartwright to avoid the excluded evidence and in asking open-ended questions that foreseeably invited a harmful answer. The circuit court denied the motion, finding the State’s conduct was neither intentional nor reckless. The Appellate Court of Maryland affirmed.
The Court’s Holding
The Supreme Court of Maryland affirmed, resolving the case on the narrowest available ground. The Court assumed—without deciding—that Maryland’s common law double jeopardy prohibition bars a third prosecution where the State’s reckless conduct caused a defendant to successfully move for a mistrial. Even under that assumed standard, the Court held that the circuit court’s factual finding that the State did not act recklessly was not clearly erroneous, and therefore Santana’s motion to dismiss was properly denied.
The Court emphasized the demanding nature of the clearly erroneous standard: a factual finding must stand if any competent evidence supports it. Here, the record showed the State had prepped Cartwright to testify about a cellphone, had instructed him to put away his supplemental report after using it only to confirm an address, and had reasonably relied on the fact that Cartwright had successfully avoided the excluded evidence throughout Santana I. The State’s surprise at Cartwright’s answer was consistent with an absence of recklessness. While Santana’s dissatisfaction with the State’s preparation was understandable, that dissatisfaction did not render the circuit court’s contrary finding clearly erroneous.
The Court expressly declined to resolve two significant open questions: whether Maryland’s common law double jeopardy doctrine applies to mistrials at all (as distinct from acquittals or convictions), and, if it does, whether recklessness—as opposed to intentional goading—is the correct trigger for barring retrial. Three justices (Watts, Biran, and Gould) dissented.
Key Takeaways
- The Supreme Court of Maryland assumed without deciding that reckless prosecutorial conduct causing a mistrial can trigger Maryland’s common law double jeopardy bar—but declined to formally adopt that rule, leaving the question open for a future case.
- Appellate review of a trial court’s finding on prosecutorial mental state is highly deferential: the clearly erroneous standard requires affirmance if any competent evidence supports the finding below.
- On these facts, the State’s failure to explicitly instruct its witness to avoid previously excluded evidence did not constitute recklessness where the State had prepared the witness on the relevant topic and reasonably expected testimony consistent with the prior trial.
- Two additional threshold questions remain unresolved under Maryland common law: whether mistrials implicate double jeopardy at all absent a factual finding on guilt or innocence, and what mental-state standard governs if they do.
Why It Matters
This decision is significant for what it leaves unanswered. Maryland is one of a handful of states that grounds double jeopardy protections in common law rather than a state constitutional provision, giving its high court latitude to develop those protections independently of federal doctrine. Under federal law (Oregon v. Kennedy), only intentional prosecutorial goading bars retrial after a defendant-requested mistrial. By assuming—without endorsing—a broader recklessness standard, the Court signals that Maryland may eventually go further than the Fifth Amendment requires, aligning with states that have already expanded their double jeopardy protections beyond the federal floor.
For practitioners, the case is a reminder that preserving the record on prosecutorial state of mind is critical when seeking dismissal on double jeopardy grounds after a mistrial. A circuit court’s finding on recklessness or intent is a factual one, entitled to substantial deference, and a defendant who cannot show clear error on appeal will be bound for a third trial. Defense counsel who suspect recklessness should develop a detailed evidentiary record—covering witness preparation, prior pretrial agreements, and the foreseeability of the harmful testimony—before the motion to dismiss is heard.
