John Ellsworth Hasselbrink, 41, a white male, died in the early hours of April 15, 2018, in Ewa Beach, Hawaiʻi, after a night that was supposed to end quietly at home. He was a Navy chief petty officer stationed in the Pearl Harbor submarine community, and in the small hours before daybreak he wound up at the wrong front door—close enough to his own place that the mistake would later be described as tragic and irreversible.
Police accounts and later court reporting described him trying to get inside a neighbor's townhouse, working the doorknob and pressing against the door as if he believed he was locked out of his own home. Inside, the resident—identified as Gregory A. Farr, an Army veteran—was jolted awake by the noise and the barking of his dog. Farr said he shouted to ask who was there and, getting no clear answer, feared an intruder was trying to force entry. He armed himself and, from behind the closed door, fired a single shot through it. Hasselbrink was struck and died at the scene, collapsing on the porch just outside the doorway he had been trying to open.
In the immediate aftermath, authorities treated the shooting as a serious criminal investigation. The resident who fired the shot was arrested at first, then released without charges while detectives continued gathering evidence. As the case developed, prosecutors later filed charges, accusing Farr of recklessly causing Hasselbrink's death. He was charged with felony manslaughter, along with two counts of possession of unregistered firearms, according to court records referenced in reporting at the time.
The prosecution did not move in a straight line. In 2019, reporting described the manslaughter case being dismissed on speedy-trial grounds after a judge found the deadline to bring the case to trial had been violated, including delays tied to missed submission deadlines for evidence. Even then, the door was not fully shut: a judge indicated the state could refile the case, leaving the possibility of renewed prosecution hanging over the shooting.
Years later, the case returned to a jury. By July 2022, jurors were deliberating on whether Farr was guilty of manslaughter for firing from inside his locked home at a neighbor who, according to the state's theory, was not an actual intruder but a man at the wrong door. The trial ended without a final resolution when a judge declared a mistrial after jurors could not reach a unanimous verdict, leaving the outcome unsettled in the public record available through the sources reviewed.
