Amber Alert issued for missing 3‑year‑old Joshua Ovalles in Beaverton

Missing toddler spotted near Beaverton’s western corridor

At about 10 a.m. on Tuesday, October 6, 2026, 3‑year‑old Joshua Ovalles was seen in the vicinity of SW Western Avenue and SW Beaverton Hillsdale Highway, according to the Beaverton Police Department. He was last observed with a woman identified as Mari Martinez. Investigators believe the pair left the area in a white 2022 Mercedes GLB sport‑utility vehicle that carries the Oregon licence plate “MAMIII.”

Who is involved

• Joshua Ovalles – the missing child, age three.
• Mari Martinez – the adult seen with Joshua; police have not disclosed her relationship to the child.
• Beaverton Police Department – the agency that issued the Amber Alert and is coordinating the search.
• Mercedes‑Benz GLB (2022) – the vehicle described in the alert, registered in Oregon.

The alert was first released by the Beaverton Police Department and then amplified by local broadcasters KATU, KTVZ and KCBY. All three outlets repeat the same core details: the child’s name and age, the last‑known location, the woman’s name, and the description of the white Mercedes GLB with the plate “MAMIII.”

What authorities are asking the public

Police have activated an Amber Alert, a national child‑abduction notification system, to maximise the speed of information flow. They urge anyone who sees the described vehicle—or who may have any clue about Joshua’s whereabouts—to call 911 immediately or use the dedicated tip line 1‑866‑526‑2375 (also advertised as 1‑866‑5 AMBER 5). The tip line is staffed 24 hours a day.

“If you have any information, please call 911 or the Amber Alert hotline right away,” the Beaverton Police Department statement read.

The department has not released a photo of Mari Martinez, nor have they clarified whether she is a caregiver, a relative, or an unknown party.

How the Amber Alert works

When an Amber Alert is issued, broadcasters, highway‑change message signs, and wireless‑phone carriers broadcast the child’s description and vehicle details. In Oregon, the alert also appears on the state’s emergency alert system and on the National Center for Missing & Exploited Children website.

Next steps

Law‑enforcement officers are conducting a ground search in the neighbourhood surrounding the last‑known sighting, and they have dispatched units to monitor traffic for the white Mercedes GLB. Residents have reported heightened vigilance, with many checking their driveways and side streets for the vehicle.

The case remains active, and officials say they will update the public as soon as new information becomes available. Until then, the community’s eyes and ears are the best hope of bringing Joshua Ovalles home safely.
