A Feather Alert is a statewide notification issued by the California Highway Patrol for missing Indigenous people who are considered at risk due to age, disability or suspicious circumstances. The system, created in 2023 under California law, functions similarly to an Amber Alert but is specific to Native American and Indigenous individuals and was established in response to disproportionately high rates of missing and murdered Indigenous people.

He looks more like he’s associated with surenos than round valley based on his tattoo by his eye.
Crazy to me how being proud of being white in wildly racist yet the state votes to call a missing native American a “feather alert”
He’s a missing person.
You drastically misunderstand, Derp.
You’re conflating (blending what should not be) “pride in one’s heritage” (not racist, no matter the race and/or geographical origin) with White (or insert any other racial origin) Supremacy (hyper racist).
RedsAppleAle, does that matter? Not only is he a missing person, he’s a father and has several loved ones extremely concerned. His affiliation has nothing to do with his wellbeing.
So many people end up coming to the ocean/beach. Is this possible?
