David Smith, a 49-year-old Caucasian man, was found dead inside a Buck Street residence in Nashua, New Hampshire, just after midnight on July 8, 2018. Neighbors described him as a quiet man. Police initially called the death suspicious, and the Chief Medical Examiner’s autopsy the next day ruled the death a homicide from a single gunshot wound to the head.

Investigators from the Nashua Police Department and the New Hampshire Attorney General’s Office later developed evidence that the killing occurred during a robbery plotted by people from Connecticut. Indictments returned in March 2022 named Clinton Turner, then 30, of New Haven, Connecticut, on charges including acting as an accomplice to second-degree murder, conspiracy to commit robbery, and robbery; Diana Hazard, 32, of Connecticut, was indicted on accomplice and misdemeanor theft-related charges. Authorities identified 41-year-old Tramaine Poole, also of New Haven, as the shooter; Poole was itself killed about a month after Smith’s murder in a shootout with Virginia State Police while in a stolen vehicle.

Who among neighbors or anyone who knew David can add detail about his last days or about activity near Buck Street the night of July 8, 2018?
