AUSTIN, Texas — A former elementary school teacher in Austin has pleaded guilty in federal court to possession of child pornography. Carl David Innmon, a 51-year-old former fifth-grade teacher, was found with over 16,000 files depicting child sexual abuse material on a laptop and an additional 349,728 files on an external hard drive, according to court documents.

Innmon, who was arrested in April 2025, had previously worked as a substitute teacher at approximately 20 other schools within the Austin Independent School District. He faces up to 20 years in prison, with sentencing to be determined by a federal district court judge after considering the U.S. Sentencing Guidelines and other statutory factors.

The announcement was made by U.S. Attorney Justin R. Simmons for the Western District of Texas. The case is being investigated by the FBI and the Texas Department of Public Safety Criminal Investigations Division, with Assistant U.S. Attorney Grant Sparks prosecuting.

This case is part of Project Safe Childhood, a nationwide initiative launched by the Department of Justice in May 2006 to combat child sexual exploitation and abuse. The initiative aims to locate, apprehend, and prosecute individuals who exploit children via the Internet and to identify and rescue victims. For more information, visit www.justice.gov/psc.
