On 11/3/2023, at about 5:39 p.m., Humboldt County Sheriff’s deputies were dispatched to the 39000 block of State Hwy 299 near Willow Creek for the report of a male subject waving a knife.

The deputy arrived on scene and located a male subject in the Coast Community Credit Union parking lot. The deputy observed 36-year-old Andrew Mianecki brandishing a large knife and threatening a nearby individual. The deputy requested assistance and held Mianecki at gunpoint, directing him to drop the knife. Mianecki refused and concealed the knife in his front sweatshirt pocket. The deputy continued giving commands to Mianecki until additional deputies arrived on scene. After about 10 minutes, Mianecki complied with deputy commands and was detained without further incident.

Upon investigation, the deputy learned Mianecki had threatened to kill the victim with the knife. The deputy also learned Mianecki had threatened an additional victim and attempted to stab them with a knife. Neither victim was injured during the incident.

Mianecki was taken into custody and booked for attempted murder (PC 664/187(A)), brandishing a deadly weapon (PC 417(A)(1)), criminal threats (PC 422(A)), resisting arrest (PC 148(A)(1), and assault with a deadly weapon (PC 245(A)(1)).
