Court finds courthouse arson defendant competent, robbery trial delayed to June

Stephen Paul Paiment, the McKinleyville man accused of torching his car on the Humboldt County Courthouse lawn, was found competent to stand trial, keeping one of Eureka’s most visible cases on a criminal track while other matters slipped deeper into delay.

Paiment’s arrest began the night of Aug. 23, 2025, when Eureka police and Humboldt Bay Fire responded at about 7:51 p.m. to the 800 block of 5th Street. Officers said Paiment drove a white sedan onto the front lawn of the courthouse, got out and deliberately set it on fire. Several witnesses identified him, police said, and no one was hurt. He was booked into the Humboldt County Correctional Facility after the fire, which left damage on county property and turned the courthouse itself into the scene of the crime.

The arson case has carried extra weight because it was tied to Paiment’s protests over an alleged police use-of-force incident and to anti-nuclear-power messages found at the scene. The District Attorney’s Office charged him with three crimes tied to the fire, including felony arson and littering, with the damaged property identified as the courthouse lawn belonging to the County of Humboldt. A competency ruling does not end the case, but it does determine whether the court can move forward with the charges as a trial case instead of pausing for treatment or more evaluation.

That question of whether the system can keep moving is now part of the larger story in Humboldt County Superior Court. A disbarred attorney failed to appear in a separate matter, another sign that not every case is advancing on schedule. And a robbery trial involving WinCo Foods was pushed into June, extending the wait for victims, defendants and witnesses who have already been drawn into the county’s crowded courtroom calendar.

The pace has been uneven before. In March, another Humboldt jury deadlocked 7-5 in favor of acquittal after 12 days of testimony and nearly a week of deliberations, forcing Judge Killoran to declare a mistrial. Taken together, the rulings, no-shows and continuances show a courthouse handling serious criminal cases under strain, where accountability can still be reached, but often only after long delays.
