A 14-year-old Washington state student’s detailed massacre plot was thwarted only because a vigilant citizen in Florida spotted his TikTok video showing a color-coded school map with tactical annotations.
Story Snapshot
- Teen posted TikTok video with color-coded Kamiakin High School map labeled with “targets,” “gear up,” and “exit” points
- Florida resident’s FBI tip led to discovery of 24 firearms, manifesto, and detailed attack plans at suspect’s home
- Mason Bently-Ray Ashby, 14, charged with attempted murder but cannot be tried as adult due to Washington juvenile laws
- Case demonstrates critical role of public vigilance and social media monitoring in preventing school violence
Social Media Tip Prevents Potential Massacre
Mason Bently-Ray Ashby filmed himself inside Kamiakin High School on September 19, 2025, displaying a meticulously crafted color-coded map of the building. The map contained tactical annotations including “gear up,” “potential targets,” “targets,” “glass,” “be wary of,” and “exit.” A concerned Florida resident who saw the TikTok video immediately contacted the FBI, triggering an interstate investigation that likely prevented a catastrophic attack.
Extensive Arsenal and Planning Materials Discovered
FBI agents and Kennewick police executed a search warrant at the teen’s grandparents’ home on September 30, uncovering a shocking cache of evidence. Investigators seized 24 firearms, a detailed manifesto outlining the suspect’s motivations, and additional tactical research materials. The suspect had been living with his grandparents, who were reportedly unaware of his deadly intentions and extensive planning activities.

Juvenile Justice System Limits Prosecution Options
Benton County Prosecutor Eric Eisinger charged Ashby with attempted murder and multiple weapons offenses, setting bail at $1 million. However, Washington state juvenile laws prevent prosecutors from charging the 14-year-old as an adult for attempted murder, highlighting significant gaps in the justice system’s ability to handle serious juvenile crimes. This limitation underscores the need for legislative reform to ensure appropriate consequences for would-be mass shooters regardless of age.
Case Highlights Critical Role of Citizen Vigilance
This incident demonstrates how ordinary citizens can serve as America’s first line of defense against domestic terrorism. The Florida resident’s quick thinking and immediate reporting to authorities exemplifies the type of vigilance needed to protect our schools and communities. Law enforcement officials emphasized that public awareness and rapid reporting of suspicious online activity are essential tools in preventing violence before it occurs.
