State v. Villanueva, 352 Conn. 439

Defendant Davis Roman Villanueva was convicted of murder, carrying a pistol without a permit, and criminal possession of a firearm following a deadly shooting outside Mr. Bentley’s Café in Meriden, Connecticut, in 2020.
The incident was captured on surveillance cameras, and an eyewitness, Diana Baez, provided statements and a photographic identification of the defendant.
Police investigation included DNA evidence from a beer can, video footage, and out-of-court identifications by Baez and another witness who knew the defendant.
At trial, defense counsel requested a jury instruction on alleged inadequacies in the police investigation (e.g., failure to investigate other suspects or perform a victimology), challenged the admissibility of Baez’s out-of-court identification, and objected to certain medical examiner testimony.
The trial court denied the requests and objections; the defendant was convicted and appealed on grounds tied to the right to present a defense, due process, and confrontation clause violations.

Issue	Defendant Argument	State Response	Held
Right to jury instruction on police investigative inadequacy	Police failed to investigate alternative suspects or conduct key procedures, justifying an instruction to the jury	No record evidence that investigations were inadequate; defense provided no substantive support for claims	Denied; no evidence supported giving the instruction
Admissibility of out-of-court eyewitness identification	Identification was suggestive due to lack of mandated instruction and prior police threats to witness	Eyewitness was not pressured during identification procedure; proper instructions were substantially given	Denied; procedure was not unnecessarily suggestive, identification was reliable
Admission of medical examiner testimony (not the autopsy performer)	Substitute examiner’s opinions relayed conclusions of nontestifying examiner; confrontation clause violation	Substitute testified only to own conclusions based on photographs, not on former examiner’s report	Mostly denied; testimony about photographs was allowed, any errors held harmless
