A former McLoud High School teacher is facing charges for allegedly sending illicit text messages to students. 43-year-old Serena Cator is accused of sending nude pictures and sexually-charged messages to at least three teenagers between the ages of 14-to-18, and requesting nude pictures from them. According to officers, Cator said two of the students had previously been in a relationship with her daughter. McLoud Public Schools says Cator was placed on administrative leave after the district learned of the allegations last September, and hasn't been an M-P-S employee since December.
