Former McKinney North trainer arrested again in child sex abuse case

A former McKinney North High School athletic trainer was rearrested March 25 on new child sex abuse charges, deepening a case that has already led to her firing, a civil lawsuit and fresh scrutiny over how McKinney ISD handled the warning signs.

Lindsey Elizabeth Post now faces two counts of indecency with a child by sexual contact and a charge of violating a protective order that had been imposed as a bond condition. Her first arrest came Jan. 28, when McKinney police said she was booked on charges of sexual assault of a child and improper relationship between an educator and a student, both second-degree felonies. She later bonded out of the Collin County Jail.

The allegations center on a 14-year-old McKinney North student who was a first-year high schooler. Court filings and reporting on the family’s civil case say the abuse happened multiple times between early November 2025 and early January 2026, with contact both on and off campus. WFAA reported that the trips included rides in Post’s car to school-related events and other locations investigators believe were tied to the abuse. Text messages cited in court records allegedly included, “I miss you baby” and “I love you baby.”

McKinney ISD said it was notified Jan. 27 of inappropriate text messages and/or conduct involving Post and a McKinney North student. The district said it reported the matter to the Texas Education Agency’s State Board for Educator Certification, the Texas Department of Family and Protective Services and McKinney police. The district later said Post worked not only at McKinney North, but also supported Cockrill Middle School and Scott Johnson Middle School. On Feb. 26, the school board voted to approve her mid-year termination effective that day after a special meeting earlier that month considered notice of proposed termination.

The family’s lawsuit, reported in early March, accuses McKinney ISD of gross negligence and says the district’s failure to take preventative action, including termination, helped enable the abuse. Attorney Paul Herz has said the case is meant to hold adults and institutions accountable, discourage similar conduct in schools and encourage other possible victims to come forward. NBC 5 also reported that Herz questioned whether Post was properly licensed in Texas at the time of the alleged incidents.

The case now reaches across multiple campuses in a district serving thousands of children. McKinney North High School enrolls more than 2,500 students in grades 9 through 12, a reminder that the trust placed in athletic trainers and other school staff can shape safety far beyond one locker room or training table.
