Athletic trainer accused of sexually assaulting a high schooler fired by McKinney ISD
An athletic trainer charged with sexually assaulting a 14-year-old student has been fired by the McKinney ISD Board of Trustees.
In a meeting on Thursday, the district's board "voted to terminate" Lindsey Post's immediate employment.
McKinney Police arrested Post on Jan. 28 after investigators accused her of grooming and then raping a first-year student at McKinney North High School.
"The district felt it was important to immediately and purposefully act regarding the alleged conduct underlying Ms. Post's arrest," officials said in a statement.
Earlier Thursday, the family of the teenager filed a $1 million civil lawsuit against Post and the district.
Post faces two charges, including sexual assault of a child and improper relationship between an educator and student. She was booked into the Collin County Jail and later posted $125,000 bond.
In addition to the assault allegations against Post, the suit claims McKinney ISD was grossly negligent in supervising Post.
Suspect worked at several schools
Post worked as an athletic trainer at McKinney North High School and also provided support at Cockrill Middle School and Scott Johnson Middle School, according to the district.
"This is a case of the grooming and serial rape of a 14-year-old first-year high schooler," the suit said.
Court documents allege that during the 2025-26 fall semester, Post worked to build trust with the student while "exceeding clearly established norms and boundaries for school employee-student interaction."
"When Post had the child in her clutches, Post purported to confess her feelings for the 14-year-old, and began messaging the child's personal telephone number," the suit said.
Physical contact alleged
The suit also alleges Post hugged and kissed the teen at school and later lured the student into her car, where the assaults occurred.
"Unbeknownst to the parents, this criminal pattern of taking the child away from the school to rape the child recurred multiple times in that month and thereafter," the suit said.
The suit was filed by Dallas attorney Paul Herz, who is also representing other Collin County sexual‑abuse plaintiffs, including those who allege abuse by former Celina ISD coach and teacher Caleb Elliott.
McKinney ISD response
McKinney ISD said it has hired an independent third-party investigator to assist in the investigation of the areas unrelated to the criminal investigation.
"The investigation includes, but is not limited to, questions related to Ms. Post's licensure," the district said.
In a letter sent to parents shortly after Post's arrest, McKinney ISD Superintendent Shawn Pratt said the district immediately notified McKinney police, the Texas Education Agency's State Board for Educator Certification, and the Texas Department of Family and Protective Services.
"The safety and well-being of our students is our highest priority," Pratt said. "Following clearance by law enforcement, Ms. Post was placed on administrative leave pending investigation."
