She Lived Fiercely. He Took It Away: The Murder of Onyx Cornish

Hope “Onyx” Cornish was just 18 years old when her life was stolen inside her Caldwell, Idaho home. Bold, stylish, and unapologetically herself, Onyx was queer, trans, and known for her kindness, empathy, and fierce individuality. She was thriving—sober for over a year, in a new relationship, working shifts at Wendy’s—when her adoptive father, Delbert Cornish, carried out a plan he admitted he had been thinking about for more than a year. On August 18, 2025, Delbert shot his daughter in the head, then draped her body in a Pride flag in what he later claimed was a twisted gesture of “honor.” He wrote suicide notes on the walls, killed her cat, and confessed that he had wanted to kill all of his children before taking his own life. Onyx’s younger brother fought back, disarming him and escaping, saving his own life in the process. Now, Delbert faces charges of first-degree murder, aggravated assault, and animal cruelty. Prosecutors say their case is built on overwhelming evidence, including Delbert’s own confessions and notes. A trial date is set for January 2026. Meanwhile, Onyx’s family, friends, and community continue to mourn and demand justice—not just in the courtroom, but in how she is remembered: as an outspoken, radiant teen who lived authentically in a world that too often wanted her quiet.
