A high school mathematics teacher in Florida has been arrested following allegations of engaging in a sexual relationship with a student. The investigation was triggered when vigilant parents tracked their son’s whereabouts to an unexpected location.

Kirsten Rose, aged 37, who teaches at Cocoa Beach Jr./Sr. High School, was apprehended by the Brevard County Sheriff’s Office in connection to these accusations.

The inquiry commenced in March after a male student’s parents suspected an improper affair with a teacher. Their concerns arose when their son returned home late from work and was evasive about his whereabouts, as detailed by the sheriff’s office.

Upon checking his location, the parents discovered he had been at an unfamiliar residence. Initially, the teenager claimed to have been at a girlfriend’s house, but later confessed to being involved with his teacher, according to investigators.

Kirsten Rose, 37, has been charged with five counts of unlawful sexual activity with a minor, based on allegations of a sexual relationship with a male student.

Investigators revealed that Rose and the student began exchanging private messages on Instagram starting in November 2025. The relationship reportedly became sexual in February and persisted into March, authorities stated.
