Marty Duwayne Griego, 52, a former elementary school teacher for the Northwest Independent School District in Denton, has been convicted of sexually abusing a girl who lives with autism. The abuse occurred over a period of one year, according to prosecutors.
Griego is now facing a potential sentence of 50 years in prison as a result of the conviction. Denton is located approximately 11 miles southwest of Aubrey.
While the conviction relates specifically to the abuse of the minor, separate federal charges have been filed against Griego. Prosecutors allege that child pornography was discovered on his mobile phone. The source does not specify if these federal charges are part of the same case or a distinct legal proceeding.
Details regarding the specific timeline of the federal investigation or the current status of those separate charges were not provided in the available reporting. Further information on the sentencing proceedings or Griego's legal representation is not yet clear.
