Commonwealth v. Gumkowski

Summary

The Massachusetts Supreme Judicial Court affirmed Matthew Gumkowski’s conviction for murder in the first degree on a theory of extreme atrocity or cruelty. The court held that law enforcement obtained the defendant’s cell site location information through state action without a warrant, but concluded that admission of the information was harmless beyond a reasonable doubt and that the challenged evidence was not fruit of the poisonous tree. The court also rejected the defendant’s challenges to seven aspects of the jury instructions and declined to exercise its authority under G. L. c. 278, § 33E.

Holdings

1. Individuals have a reasonable expectation of privacy in more than six hours of CSLI, and law enforcement must obtain a warrant before acquiring such CSLI. When law enforcement initiates the acquisition by requesting records from a cellular provider, the acquisition constitutes State action even if the request is made under the voluntary-disclosure provision of the Stored Communications Act.
2. Admission of the defendant's CSLI was harmless beyond a reasonable doubt.
3. The call logs and the defendant's arrest, including clothing and other evidence seized after the arrest, were not fruits of the unlawfully obtained CSLI because they were not derived from or obtained through exploitation of that CSLI.
4. The challenged instructions, considered as a whole, did not create a substantial likelihood of a miscarriage of justice. Although the circumstantial-evidence hypothetical was erroneous because it closely mirrored the prosecution's evidence and illustrated how a defendant could be found guilty, the error was not prejudicial in the context of the entire charge and the strong evidence of guilt.

Questions Presented

1. Whether law enforcement's warrantless acquisition of the defendant's CSLI under the voluntary-disclosure provision of the Stored Communications Act violated the Massachusetts Declaration of Rights or the Fourth Amendment.
2. Whether the call logs and evidence seized following the defendant's arrest were fruits of the unlawfully obtained CSLI.
3. Whether admission of the CSLI was harmless beyond a reasonable doubt.
4. Whether seven challenged jury instructions created a substantial likelihood of a miscarriage of justice, including instructions concerning factual questions, witness bias, exhibit-versus-testimony conflicts, a videotaped statement, circumstantial evidence, reasonable inferences, and proof of the elements.
5. Whether relief was warranted under the Supreme Judicial Court's plenary review authority under G. L. c. 278, § 33E.
