Parents are suing McKinney Independent School District for allegedly enabling a female employee to sexually abuse their 14-year-old daughter.
The lawsuit, filed on February 26, also names McKinney North High School athletic trainer Lindsey Post as a defendant.
Post, 36, was arrested on January 28 after the student’s family discovered sexually explicit messages from the trainer to the girl.
The girl, identified in the lawsuit as Minor Doe, then revealed that Post had subjected her to sexual activity.
Post was charged with sexual assault of a child and improper relationship between educator and student—both second-degree felonies punishable by 2 to 20 years in prison.
The student’s family then hired attorney Paul Herz, who is also representing several families suing Celina ISD over a locker room recording scandal involving then-middle school coach Caleb Elliott.
In a statement released at that time, Herz urged McKinney ISD to “immediately reform its policies, procedures, and practices to protect its student body, which remains susceptible to the same abuse until something changes.”
According to the lawsuit, Post began grooming the student in 2025, both at school and by messaging the girl’s phone.
The suit alleges Post subsequently physically assaulted the girl on campus and while the student was in the trainer’s car being driven to school-sponsored events.
“Unbeknownst to the parents, this criminal pattern of taking the child away from the school to rape the child recurred multiple times,” the plaintiffs’ petition states. “Due to Post’s thorough manipulation and grooming of the impressionable child, Minor Doe did not believe it was safe or feasible to escape the car or otherwise to make an outcry.”
The lawsuit calls Post’s conduct “beyond all possible bounds of decency”—in particular, because Post “sought to be, and was, entrusted with the safety of young children” in a profession that “enabled personal and physical contact with children for legitimate purposes, but which trust and contact Post violated and bent to her own prurient interest, over the wellbeing of said children.”
The lawsuit also claims McKinney ISD was “grossly negligent” for failing to ensure supervised transportation to extracurricular events that students were expected to attend, and failing to have or enforce a policy against a school employee taking a student away from campus in the employee’s own vehicle, among other charges.
A new law passed in 2025 waives school districts’ immunity from civil liability if a district is grossly negligent or reckless in hiring or supervising a school employee who sexually abuses a student.
The plaintiffs are seeking actual and exemplary monetary damages.
McKinney ISD placed Post on administrative leave when the allegations arose. Trustees voted to terminate her contract during a special school board meeting on February 26.
Post does not hold a Texas teaching certificate. She is listed as “under investigation” in the state’s Do Not Hire Registry.
In just the past few years, hundreds of Texas school employees have been accused of sex crimes involving students and other minors. Thousands have been reported to the Texas Education Agency for sexual misconduct.
