Investigators say the victim threatened to expose the relationship if the Dickinson ISD teacher didn't buy him a gun and give him $2,000.
Kara Hernandez, a former Ronald Thornton Middle School teacher, is facing charges for allegedly having sexual contact with a student in 2022.
The student, who was 17 years old at the time, reported the encounter to another teacher, who notified Nimitz Senior High School administrators in January 2025.
The 39-year-old teacher faces several charges after allegedly sexually assaulting at least six students in his classroom at KIPP Houston High School.
The former teacher, facing charges of soliciting a minor and sexual performance of a child, is also the son of the Edna ISD superintendent.
Authorities say that after the student gave permission for the teacher to pick her up, he took her to a location in Polk County and engaged in sex acts with her in the back of his vehicle before dropping her off at her residence.
