(KCEN) -- In North Texas, after a year-long investigation, a former teacher is charged with having sexual relationships with four different students.
Investigators say the parents of a high school graduate reported their son was living with his former teacher Tonya Flink.
The young man told police he'd started a relationship with her after she offered to help him with his grades after school.
A warrant shows Flink pushed herself on the student and that their sexual relationship involved everything you could imagine.
Flink is currently free on bond.
