A former elementary school teacher in the Northwest Independent School District has been convicted of sexually abusing a student who lives with autism. Marty Duwayne Griego, 52, was found guilty of the offenses, which prosecutors stated occurred over a period of one year. The Denton resident now faces a potential sentence of 50 years in prison.
In addition to the abuse conviction, Griego is confronting federal charges related to the possession of child pornography on his mobile device. Prosecutors indicated that law enforcement officers discovered the illegal material during their investigation.
The case highlights the legal consequences for educators who violate trust within school districts. Griego’s conviction marks a significant development in the prosecution of crimes involving vulnerable students. Details regarding the specific timeline of the federal charges or the current status of those proceedings were not provided in the available reports.
Further information about the sentencing date or the specific conditions of Griego’s confinement remains unclear at this time. The case underscores the ongoing efforts to protect students with special needs from exploitation.
