Overview
- Lindsey Elizabeth Post, 35, was arrested Wednesday and booked into the Collin County Jail on charges of sexual assault of a child and improper relationship between educator and student.
- Attorney Paul Herz says the student disclosed the allegations over the weekend and claims Post took the freshman off campus in her vehicle where assaults began in November; no civil lawsuit has been filed.
- McKinney ISD says it learned of the claims Tuesday, reported them to state education and child-protection authorities and police, and placed Post on administrative leave following law-enforcement clearance.
- District officials confirmed Post works at McKinney North High School and has supported Cockrill Middle School and Scott Johnson Middle School in the same role.
- Texas regulators say Post’s athletic trainer license expired Nov. 14, 2025, and TDLR has opened an enforcement investigation into potential licensing violations.
