Carl Horning, 47, was found dead the morning of Tuesday, January 2, 2024, at Horning’s Hideout in North Plains, Oregon. A lieutenant with Tualatin Valley Fire and Rescue, he had sustained multiple gunshot wounds. Deputies responded to reports of a shooting around 9:35 a.m.; attempted aid was made but he was pronounced dead at the scene.

Carl’s older brother, Robert Horning, was present when deputies arrived and was briefly detained before being released that day. The Washington County Sheriff’s Office later named Robert a person of interest as the investigation uncovered a long-running family dispute over control of Horning’s Hideout and the care of the family matriarch, Jane Horning. Court filings show Carl and a sister had sought conservatorship for their mother, alleging memory loss and financial exploitation, while Robert opposed the move.

A Washington County grand jury indicted Robert Horning on July 29, 2024; he was arrested and charged with second-degree murder and unlawful use of a weapon and pleaded not guilty. The trial ended in a mistrial after jurors reported they were deadlocked in November 2025, and the District Attorney’s Office announced plans to retry the case. Does anyone have information about the family business, court fight, or the day Carl was killed?
