A McKinney Independent School District athletic trainer was arrested Wednesday in connection with alleged sexual misconduct involving a student at McKinney North High School, authorities confirmed.
35-year-old Lindsey Post was booked into the Collin County Jail on charges of sexual assault of a child and improper relationship between educator and student, both second-degree felonies.
The McKinney Police Department said the arrest followed an investigation into inappropriate conduct and communications between Post and a student that were reported to law enforcement earlier in the week. McKinney ISD officials were notified of the allegations on Tuesday and immediately reported the matter to law enforcement and state education authorities, including the Texas Education Agency State Board for Educator Certification and the Texas Department of Family and Protective Services.
In response to the investigation, Post has been placed on administrative leave, the district confirmed. McKinney ISD said the safety and well-being of its students remain its highest priority and that it is cooperating with law enforcement while respecting legal confidentiality constraints.
Investigation details and district actions
According to police and district statements, McKinney ISD first became aware of the alleged inappropriate messages or interactions involving a McKinney North High School student on Jan. 27. After receiving the report, the district promptly notified authorities and placed Post on leave pending the ongoing investigation.
Officials have not publicly disclosed further details about the nature of the alleged conduct or the age of the student involved. Post was booked into the Collin County Jail Wednesday evening; bond information has not yet been released.
Community and legal response
In a communication to parents, McKinney ISD Superintendent Shawn Pratt said the district is fully cooperating with police and state agencies. The district encouraged anyone with information related to the case to contact McKinney Police, the Texas Department of Family and Protective Services, or the school district’s Title IX office.
Local law enforcement continues its investigation, and prosecutors will decide how to proceed as additional evidence is gathered and reviewed. No civil proceedings tied to the case have been publicly announced.
