Charlotte County deputies arrested the 37-year-old Port Charlotte High School teacher after alleging two encounters with a 17-year-old on school grounds in the past month.
Investigators said the case surfaced through the ParentSquare app, and the student told them contact began on Snapchat before she summoned him to her classroom and flirted.
Authorities said Mashburn-Smith confessed and was charged with unlawful activity with certain minors; the school district placed her on administrative leave, and the offence can carry up to 30 years in prison.
