The Dublin Police Department has charged 17-year-old Emery Toth with threatening a school shooting.
Toth, a student at Dublin Coffman High School, was charged with aggravated menacing and making false alarms. Both charges are first-degree misdemeanors.
According to an anonymous tip to the Dublin City Schools helpline, Toth had made comments about shooting other students.
Police determined there was no immediate threat to any Dublin schools or students, but say there is "sufficient evidence" that Toth threatened others with physical harm.
