Jonatan Biyembika, who is autistic and non-speaking, has been reported missing in SeaTac. An alert activated by the Washington State Patrol on September 15 identifies Biyembika.
The Endangered Missing Person Advisory, posted by WSP Missing Person Alerts
The advisory describes Biyembika as autistic and non-speaking, and notes he may have difficulty navigating independently. Anyone who spots him is urged to call 911 immediately.
The alert identifies SeaTac without naming a requesting agency. The surrounding area includes transit service, but the alert does not specify the relationship of nearby facilities or access to other cities.
A Pattern of Wandering Across South King County
A prior report by MyNorthwest documented Biyembika's disappearance in Kent in July 2025. The report also discussed his familiarity with public transportation.
Earlier reports mentioned Biyembika's familiarity with Metro buses and travel as far as Bellevue. Those reports drew attention to his movements across the region.
Why No Phone Alert Went Out
Washington has an Endangered Missing Person Advisory system for certain missing-person cases. That distinction matters for how the public learns about cases like this one.
Washington EMPA advisories can be distributed through media, emergency-management agencies, and highway signs. Public awareness therefore depends in part on those channels.
A Nationwide Safety Risk for Autistic Youth
Elopement among autistic youth can create serious safety risks. Communication challenges can compound those risks during these incidents.
Such incidents can be fatal, particularly when they involve water or traffic.
Part of a Broader Wave of South King County Alerts
Biyembika's case comes amid other searches in South King County. Hoodline previously reported on searches for 35-year-old Raughshee Nelson in Kent. The searches illustrate the challenges local authorities face when trying to locate vulnerable missing people.
Anyone who sees Jonatan Biyembika is asked to call 911 immediately. Other information should be reported to authorities.
