According to the Okanogan County Sheriff’s Office, on Saturday, May 30, 2026, private citizens conducting a search along the Okanogan River located a deceased individual in the river who was later positively identified as Matthew Brown. The Okanogan County Sheriff’s Office has stated that Matthew Brown was recovered and transferred into the custody and care of the Okanogan County Coroner. The cause and manner of death remain under investigation.
The United Cajun Navy extends our condolences to Matt Brown’s family, friends, and loved ones during this difficult time.
The O-SAR team, composed of representatives from Find 911, United Cajun Navy, Sparks SAR, Team Texas K9, Black Flag Response, and Sentinel Overwatch, rapidly mobilized to support the search for Matt Brown.
Within hours of activation, Unified Command established Command, Operations, and Intelligence functions, coordinating personnel and resources from Louisiana, Texas, Utah, Wyoming, and Florida.
Team members immediately gathered and analyzed information, developed a common operating picture, and prepared assets for deployment.
The Intelligence Branch worked with Subject Matter Experts from participating organizations to collect, organize, and analyze available information. In coordination with partners, the team developed an Incident Action Plan (IAP), identified priority search areas, and produced actionable intelligence for field operations.
Simultaneously, K9 teams, surface vessels, search personnel, and Incident Command staff were mobilized and en route to Washington State.
Using intelligence products and operational plans developed by Unified Command, the O-SAR Forward Assessment Team rapidly integrated analysis and field operations, successfully locating Matt.
Thank you Chay Moore for your dedication to the mission and the outcome. You have done good work and it’s appreciated.
Although many additional field resources were ultimately not needed, the operation demonstrated the speed, professionalism, and coordination of every organization involved. This mission highlighted the strength of partnership.
Find 911, United Cajun Navy, Sparks SAR, Team Texas K9, Black Flag Response, and Sentinel Overwatch each contributed unique capabilities, enabling the team to quickly develop intelligence, plan operations, and support successful field efforts.
Most importantly, Matt was found—the outcome everyone was working toward.
