Casillas v. ColoradoAnnotate this Case
In 2008, a juvenile probation officer swabbed the cheek of Petitioner Ismael Casillas, then a juvenile, to collect a DNA sample. The probation officer’s collection of Casillas’s DNA violated C.R.S. 19-2-925.6(1) because Casillas had been granted a one-year deferred adjudication and he was not otherwise required under the statute to submit a DNA sample. His genetic markers were nevertheless uploaded to the federal Combined DNA Index System (CODIS). Several months after Casillas successfully completed the terms of his deferred adjudication and his juvenile case had been dismissed, law enforcement investigators matched DNA evidence recovered from a stolen vehicle with the sample in the CODIS database taken from Casillas during his juvenile deferred adjudication. As a result of the DNA match, Casillas was identified and charged in connection with a carjacking. Before trial, Casillas moved to suppress all evidence derived from the DNA match, arguing that evidence derived from the unauthorized cheek swab should be excluded as the fruits of an unlawful search in violation of his Fourth Amendment rights. The trial court denied the motion, and a jury later convicted Casillas of criminal mischief. The Colorado Supreme Court granted Casillas’s petition for a writ of certiorari to review whether the exclusionary rule required suppression of the evidence derived from the juvenile probation officer’s unauthorized collection of Casillas’s DNA in this case. The Court concluded that it did, and accordingly, reversed and remanded this case with instructions to vacate Casillas’s conviction.
