California v. Marquez

In 2006, police arrested defendant Daniel Marquez in Ventura County on a drug possession offense. Without his consent, authorities collected Marquez’s DNA sample and entered his DNA profile into a statewide database. Marquez was never charged with the drug offense. In 2008, investigators retrieved DNA evidence from an Orange County robbery, and that evidence matched Marquez’s DNA profile in the database. Police contacted Marquez, and with his consent they collected a second DNA sample, which matched the DNA evidence from the robbery. The State filed two robbery counts and a related offense. The trial court denied Marquez’s motion to suppress the DNA evidence, and a jury convicted him of the charged offenses. The court sentenced Marquez to 25 years to life in state prison, plus an additional 15 years for three alleged prior serious felony convictions. The Court of Appeal held that the 2006 collection of Marquez’s DNA sample was unlawful under the Fourth Amendment; the prosecution failed to prove that Marquez was validly arrested or that his DNA was collected as part of a routine booking procedure. However, the trial court properly admitted the 2008 DNA evidence under a well-established exception to the exclusionary rule: the attenuation doctrine. Additionally, due to a recent statutory change, the Court remanded for the trial court to consider striking the additional punishment for Marquez’s three prior serious felony convictions. The Court also ordered the trial court to modify Marquez’s custody credits. In all other respects, the judgment was affirmed. View "California v. Marquez" on Justia Law
